How to Communicate with the Interviewer?

2008-10-13T23:40:00.000+05:30

Communication in the Job Interview – Essentials
In any organization, a good communicator is a positive assert and a long-term investment. Hence interviewers gauge the communication skills of the candidates. They may not be very particular about the accuracy of each answer but their primary target is fluently of expression, which you will have to demonstrate with utmost ease and facility while you respond to questions.
Your communication skills are one of the areas that an employer is looking at on the job interview. Many people will go into a job interview and say to the employer, “I have excellent communication skills.” But, if your interview suggests otherwise, then you’re just blowing hot air.
The interview gives you an opportunity to show off your communication skills. Communicating is more than just talking someone to death or listening to you talks. Communicating is a two part process. In an interview situation, you have to use active listening. Active listening basically means paying attention to what the other person is saying. Many people practice lazy listening. This is where you are not paying attention to the person speaking and you’re busy thinking about other things or what you’re going to say.
When the interviewer asks you a question, you can start off your answer by restating the question. This gives you extra time to form your answer.
For example, the interviewer asks, “How would your former employer describe you?”
Your answer would start off as, “My former employer would describe me as…”
When answering a question, keep your answers short and to the point. If you’re telling a story, keep it simple. The interviewer doesn’t need to know the life history of the people in the story. Don’t use slang or a bunch of ump’s and hubs.
Remember, you are trying to demonstrate to the interviewer that you have excellent communication skills. When you use umps and hubs throughout your answers, it signals to the interviewer that you aren’t sure of your answers or you don’t have excellent communication skills.
Practice your answers before the interview. You can’t know every question that he or she will ask you, but with the “most frequently asked questions” section of this website, you’ll be more prepared than most people.
During a job interview, a potential employer asks, “Can you take on more than one project at a time?” If you respond, “Yes,” you may want to rethink that answer. Be specific. Here’s a preferred answer to the question above, “In general, depending upon the type and length of projects, I believe I can efficiently handle more than one project at a time.” Active listening means two things: analysis and response to the message being communicated. An active listener maintains eye contact and good posture with a slight lean towards the speaker. Gestures, appearance, timing, voice responses, facial expressions, spatial distance – all affect how the speaker (or interviewer) interprets thelistener. So a person preparing for a job or work project interview should consider the cultural climate and norms of societyof the interviewer. In short, perceived active listening based on nonverbal signals can vary from culture to culture. Especially in this age of such great cultural diversity, be courteous of others regardless of cultural, sexual or societal backgrounds. If you are a woman and get to a door before a man, open it. If your interviewer doesn’t speak English very welland looks puzzled at your words, go back and explain yourself again in different words and re-establish a good communication exchange. A major part of active listening is paraphrasing. It’s not the same as summarizing. A summary is a shortened version of the original message, focusing on the main point. To paraphrase means to re-state the message in your own words. Active listeners take notes by paraphrasing or restating what the speaker said in their own words, and summarizing main points. A good listener is not the same thing as a silent listener. Good listeners ask questions, even something like, “Is this an accurate statement of what you have said?” to let the speaker know that you understand the message being communicated.

C, C++ Tech Aptitude Questions

2008-10-04T13:29:00.003+05:30

1. What is a modifier?
Answer:
A modifier, also called a modifying function is a member function that changes the value of at least one data member. In other words, an operation that modifies the state of an object. Modifiers are also known as ‘mutators’.

2. What is an accessor?
Answer:
An accessor is a class operation that does not modify the state of an object. The accessor functions need to be declared as const operations .

3. Differentiate between a template class and class template.
Answer:
Template class:
A generic definition or a parameterized class not instantiated until the client provides the needed information. It’s jargon for plain templates.
Class template:
A class template specifies how individual classes can be constructed much like the way a class specifies how individual objects can be constructed. It’s jargon for plain classes.

4. When does a name clash occur?
Answer:
A name clash occurs when a name is defined in more than one place. For example., two different class libraries could give two different classes the same name. If you try to use many class libraries at the same time, there is a fair chance that you will be unable to compile or link the program because of name clashes.

5. Define namespace.
Answer:
It is a feature in c++ to minimize name collisions in the global name space. This namespace keyword assigns a distinct name to a library that allows other libraries to use the same identifier names without creating any name collisions. Furthermore, the compiler uses the namespace signature for differentiating the definitions.

6. What is the use of ‘using’ declaration.
Answer:
A using declaration makes it possible to use a name from a namespace without the scope operator.

7. What is an Iterator class?
Answer:
A class that is used to traverse through the objects maintained by a container class. There are five categories of iterators:
 input iterators,
 output iterators,

 forward iterators,
 bidirectional iterators,
 random access.
An iterator is an entity that gives access to the contents of a container object without violating encapsulation constraints. Access to the contents is granted on a one-at a-time basis in order. The order can be storage order (as in lists and queues) or some arbitrary order (as in array indices) or according to some ordering relation (as in an ordered binary tree). The iterator is a construct, which provides an interface that, when called, yields either the next element in the container, or some value denoting the fact that there are no more elements to examine. Iterators hide the details of access to and update of the elements of a container class. The simplest and safest iterators are those that permit read-only access to the contents of a container class. The following code fragment shows how an iterator might appear in code:
cont_iter:=new cont_iterator();
x:=cont_iter.next();
while x/=none do
...
s(x);
...
x:=cont_iter.next();
end;

In this example, cont_iter is the name of the iterator. It is created on the first line by instantiation of cont_iterator class, an iterator class defined to iterate over some container class, cont. Succesive elements from the container are carried to x. The loop terminates when x is bound to some empty value. (Here, none)In the middle of the loop, there is s(x) an operation on x, the current element from the container. The next element of the container is obtained at the bottom of the loop.

9. List out some of the OODBMS available.
Answer:
 GEMSTONE/OPAL of Gemstone systems.
 ONTOS of Ontos.
 Objectivity of Objectivity inc.
 Versant of Versant object technology.
 Object store of Object Design.
 ARDENT of ARDENT software.
 POET of POET software.

10. List out some of the object-oriented methodologies.
Answer:
 Object Oriented Development (OOD) (Booch 1991,1994).
 Object Oriented Analysis and Design (OOA/D) (Coad and Yourdon 1991).
 Object Modelling Techniques (OMT) (Rumbaugh 1991).
 Object Oriented Software Engineering (Objectory) (Jacobson 1992).
 Object Oriented Analysis (OOA) (Shlaer and Mellor 1992).

11. What is an incomplete type?
Answer:
Incomplete types refers to pointers in which there is non availability of the implementation of the referenced location or it points to some location whose value is not available for modification.
Example:
int *i=0x400 // i points to address 400
*i=0; //set the value of memory location pointed by i.
Incomplete types are otherwise called uninitialized pointers.

12. What is a dangling pointer?
Answer:
A dangling pointer arises when you use the address of an object after its lifetime is over. This may occur in situations like returning addresses of the automatic variables from a function or using the address of the memory block after it is freed.

13. Differentiate between the message and method.
Answer:
Objects communicate by sending messages Provides response to a message to each other.
A message is sent to invoke a method. It is an implementation of an operation.

14. What is an adaptor class or Wrapper class?
Answer:
A class that has no functionality of its own. Its member functions hide the use of a third party software component or an object with the non-compatible interface or a nonobject- oriented implementation.

15. What is a Null object?
Answer:
It is an object of some class whose purpose is to indicate that a real object of that class does not exist. One common use for a null object is a return value from a member function that is supposed to return an object with some specified properties but cannot find such an object.

16. What is class invariant?
Answer:
A class invariant is a condition that defines all valid states for an object. It is a logical condition to ensure the correct working of a class. Class invariants must hold when an object is created, and they must be preserved under all operations of the class. In particular all class invariants are both preconditions and post-conditions for all operations or member functions of the class.

17. What do you mean by Stack unwinding?
Answer:
It is a process during exception handling when the destructor is called for all local objects between the place where the exception was thrown and where it is caught. 18. Define precondition and post-condition to a member function.

Answer:
Precondition:
A precondition is a condition that must be true on entry to a member function. A class is used correctly if preconditions are never false. An operation is not responsible for doing anything sensible if its precondition fails to hold. For example, the interface invariants of stack class say nothing about pushing yet another element on a stack that is already full. We say that isful() is a precondition of the push operation.
Post-condition:
A post-condition is a condition that must be true on exit from a member function if the precondition was valid on entry to that function. A class is implemented correctly if post-conditions are never false. For example, after pushing an element on the stack, we know that isempty() must necessarily hold. This is a post-condition of the push operation.

19. What are the conditions that have to be met for a condition to be an invariant of the
class?
Answer:
 The condition should hold at the end of every constructor.
 The condition should hold at the end of every mutator(non-const) operation.

20. What are proxy objects?
Answer:
Objects that stand for other objects are called proxy objects or surrogates.
Example:
template
class Array2D
{
public:
class Array1D
{
public:
T& operator[] (int index);
const T& operator[] (int index) const;
...
};
Array1D operator[] (int index);
const Array1D operator[] (int index) const;
...
};
The following then becomes legal:
Array2Ddata(10,20);
........
cout<Here data[3] yields an Array1D object and the operator [] invocation on that object yields the float in position(3,6) of the original two dimensional array. Clients of the Array2D class need not be aware of the presence of the Array1D class. Objects of this latter class stand for one-dimensional array objects that, conceptually, do not exist for lients of Array2D. Such clients program as if they were using real, live, two-dimensional arrays. Each Array1D object stands for a one-dimensional array that is absent from a conceptual model used by the clients of Array2D. In the above example, Array1D is a proxy class. Its instances stand for one-dimensional arrays that, conceptually, do not exist

21. Name some pure object oriented languages.
Answer:
 Smalltalk,
 Java,
 Eiffel,
 Sather.

22. Name the operators that cannot be overloaded.
Answer:
sizeof . .* .-> :: ?:

23. What is a node class?
Answer:
A node class is a class that,
 relies on the base class for services and implementation,
 provides a wider interface to te users than its base class,
 relies primarily on virtual functions in its public interface
 depends on all its direct and indirect base class
 can be understood only in the context of the base class
 can be used as base for further derivation
 can be used to create objects.
A node class is a class that has added new services or functionality beyond the services inherited from its base class.

24. What is an orthogonal base class?
Answer:
If two base classes have no overlapping methods or data they are said to be independent of, or orthogonal to each other. Orthogonal in the sense means that two classes operate in different dimensions and do not interfere with each other in any way. The same derived class may inherit such classes with no difficulty.

25. What is a container class? What are the types of container classes?
Answer:
A container class is a class that is used to hold objects in memory or external storage. A container class acts as a generic holder. A container class has a predefined ehavior and a well-known interface. A container class is a supporting class whose purpose is to hide the topology used for maintaining the list of objects in memory. When a container class contains a group of mixed objects, the container is called a heterogeneous container; when the container is holding a group of objects that are all the same, the container is called a homogeneous container.

26. What is a protocol class?
Answer:
An abstract class is a protocol class if:
 it neither contains nor inherits from classes that contain member data, non-virtual functions, or private (or protected) members of any kind.
 it has a non-inline virtual destructor defined with an empty implementation,
 all member functions other than the destructor including inherited functions, are declared pure virtual functions and left undefined.

27. What is a mixin class?
Answer:
A class that provides some but not all of the implementation for a virtual base class is often called mixin. Derivation done just for the purpose of redefining the virtual functions in the base classes is often called mixin inheritance. Mixin classes typically don't share common bases.

28. What is a concrete class?
Answer:
A concrete class is used to define a useful object that can be instantiated as an automatic variable on the program stack. The implementation of a concrete class is defined. The concrete class is not intended to be a base class and no attempt to minimize dependency on other classes in the implementation or behavior of the class.

29.What is the handle class?
Answer:
A handle is a class that maintains a pointer to an object that is programmatically accessible through the public interface of the handle class.
Explanation:
In case of abstract classes, unless one manipulates the objects of these classesthrough pointers and references, the benefits of the virtual functions are lost. User code may become dependent on details of implementation classes because an abstract type cannot be allocated statistically or on the stack without its size being known. Using pointers or references implies that the burden of memory management falls on the user. Another limitation of abstract class object is of fixed size. Classes however are used to represent concepts that require varying amounts of storage to implement them. A popular technique for dealing with these issues is to separate what is used as a single object in two parts: a handle providing the user interface and a representation holding all
or most of the object's state. The connection between the handle and the representation is typically a pointer in the handle. Often, handles have a bit more data than the simple epresentation pointer, but not much more. Hence the layout of the handle is typically table, even when the representation changes and also that handles are small enough to move around relatively freely so that the user needn’t use the pointers and the references.

30. What is an action class?
Answer:
The simplest and most obvious way to specify an action in C++ is to write a
function. However, if the action has to be delayed, has to be transmitted 'elsewhere'
before being performed, requires its own data, has to be combined with other actions, etc
then it often becomes attractive to provide the action in the form of a class that can
execute the desired action and provide other services as well. Manipulators used with
iostreams is an obvious example.
Explanation:
A common form of action class is a simple class containing just one virtual
function.
class Action
{
public:
virtual int do_it( int )=0;
virtual ~Action( );
}
Given this, we can write code say a member that can store actions for later
execution without using pointers to functions, without knowing anything about the
objects involved, and without even knowing the name of the operation it invokes. For
example:
class write_file : public Action
{
File& f;
public:
int do_it(int)
{
return fwrite( ).suceed( );
}
};
class error_message: public Action
{
response_box db(message.cstr( ),"Continue","Cancel","Retry");
switch (db.getresponse( ))
{
case 0: return 0;

case 1: abort();
case 2: current_operation.redo( );return 1;
}
};
A user of the Action class will be completely isolated from any knowledge of
derived classes such as write_file and error_message.

Interview Tips

2008-07-21T22:11:00.001+05:30

Great interviews arise from careful groundwork. You can ace your next interview if you:

Enter into a state of relaxed concentration. This is the state from which great basketball players or Olympic skaters operate. You'll need to quiet the negative self chatter in your head through meditation or visualization prior to sitting down in the meeting. You'll focus on the present moment and will be less apt to experience lapses in concentration, nervousness, self-doubt and self-condemnation.
Act spontaneous, but be well prepared. Be your authentic self, professional yet real. Engage in true conversation with your interviewer, resting on the preparation you did prior to coming to the meeting. Conduct several trial runs with another person simulating the interview before it actually occurs. It's the same as anticipating the questions you'll be asked on a final exam.
Set goals for the interview. It is your job to leave the meeting feeling secure that the interviewer knows as much as he or she possibly can about your skills, abilities, experience and achievements. If you sense there are misconceptions, clear them up before leaving. If the interviewer doesn't get around to asking you important questions, pose them yourself (diplomatically) and answer them. Don't leave the meeting without getting your own questions answered so that you have a clear idea of what you would be getting yourself into. If possible, try to get further interviews, especially with other key players.
Know the question behind the question. Ultimately, every question boils down to, "Why should we hire you?" Be sure you answer that completely. If there is a question about your meeting deadlines, consider whether the interviewer is probing delicately about your personal life, careful not to ask you whether your family responsibilities will interfere with your work. Find away to address fears if you sense they are present.
Follow up with an effective "thank you" letter. Don't write this letter lightly. It is another opportunity to market yourself. Find some areas discussed in the meeting and expand upon them in your letter. Writing a letter after a meeting is a very minimum. Standing out among the other candidates will occur if you thoughtfully consider this follow up letter as an additional interview in which you get to do all the talking. Propose useful ideas that demonstrate your added value to the team.
Consider the interviewer's agenda. Much is on the shoulders of the interviewer. He or she has the responsibility of hiring the right candidate. Your ability to do the job will need to be justified. "Are there additional pluses here?" "Will this person fit the culture of this organization?" These as well as other questions will be heavily on the interviewer's mind.
Find ways to demonstrate your qualities above and beyond just doing the job.Expect to answer the question, "Tell me about yourself." This is a pet question of prepared and even unprepared interviewers. Everything you include should answer the question, "Why should we hire you?" Carefully prepare your answer to include examples of achievements from your work life that closely match the elements of the job before you. Obviously, you'll want to know as much about the job description as you can before you respond to the question.
Watch those nonverbal clues. Experts estimate that words express only 30% to 35% of what people actually communicate; facial expressions and body movements and actions convey the rest. Make and keep eye contact. Walk and sit with a confident air. Lean toward an interviewer to show interest and enthusiasm. Speak with a well-modulated voice that supports appropriate excitement for the opportunity before you.
Be smart about money questions. Don't fall into the trap of telling the interviewer your financial expectations. You may be asking for too little or too much money and in each case ruin your chances of being offered the job. Instead, ask what salary range the job falls in. Attempt to postpone a money discussion until you have a better understanding of the scope of responsibilities of the job.
Don't hang out your dirty laundry. Be careful not to bare your soul and tell tales that are inappropriate or beyond the scope of the interview. State your previous experience in the most positive terms. Even if you disagreed with a former employer, express your enthusiasm for earlier situations as much as you can. Whenever you speak negatively about another person or situation in which you were directly involved, you run the risk (early in the relationship) of appearing like a troubled person who may have difficulty working with others.

Group Discussion Tips

2008-07-21T22:04:00.001+05:30

A group discussion (GD) is a simulated exercise, where you cannot suddenly put up a show, since the evaluators will see through you easily. In this page you can find tips on GD and how to handle them to ensure a positive outcome. Here's how most group discussions work :
Normally groups of 8-10 candidates are formed into a leaderless group, and are given a specific situation to analyze and discuss within a given time limit.

The group may be given a case study and asked to come out with a solution for a problem.
The group may be given a topic and asked to discuss on the same. A panel will observe the proceedings and evaluate the members of the group. OBJECTIVELets start from the basic.
One needs to know what one's objective in the group is. A good definition of your objective is - to be noticed to have contributed meaningfully in an attempt to help the group reach the right consensus. What does this essentially mean?The first implication is that you should be noticed by the panel. Merely making a meaningful contribution and helping the group arrive at a consensus is not enough. You have to be seen by the evaluating panel to have made the meaningful contribution. What does that mean in practice?
You must ensure that the group hears you. If the group hears you, so will the evaluator. That does not mean that you shout at the top of your voice and be noticed for the wrong reasons.
You have to be assertive. If you are not a very assertive person, you will have to simply learn to be assertive for those 15 minutes. Remember, assertiveness does not mean being bull-headed or being arrogant.
And most importantly, you have to make your chances. Many group discussion participants often complain that they did not get a chance to speak. The fact is that in no group discussion will you get a chance to speak. There is nothing more unacceptable in a GD than keeping one's mouth shut or just murmuring things which are inaudible.
Participate in as many practice GDs as possible before you attend the actual GD. There is nothing like practice to help you overcome the fear of talking in a GD.

The second important implication is that making just any sort of contribution is not enough. Your contribution has to be meaningful. A meaningful contribution suggests that, You have a good knowledge baseYou are able to put forth your arguments logically and are a good communicator.
The quality of what you said is more valuable than the quantity. There is this myth amongst many group discussion participants that the way to succeed in a group discussion is by speaking loudly and at great length. One could not be more wrong. You must have meat in your arguments. Therefore, think things through carefully.

Always enter the room with a piece of paper and a pen.
In the first two minutes jot down as many ideas as you can.
When you jot down points, keep these pointers in mind.
If it is a topic where you are expected to take a stand, say for example, "Should India sign the Comprehensive Test Ban Treaty?" note down points for both sides of the argument. It will be useful on two counts.

One, if you do not start the GD and are not amongst the first five speakers and find that everyone in the group is talking for the topic, then it makes sense to take the alternate approach and oppose the topic even if you initially intended to talk for the topic.
Second, it helps to have a knowledge of how group members who take a stand diametrically opposite to yours will put forth their argument and to be prepared with counter arguments.

Everybody else will state the obvious. So highlight some points that are not obvious. The different perspective that you bring to the group will be highly apprecaited by the panel.
Some pointers on being relevant while having a different perspective are:
Be careful that the "something different" you state is still relevant to the topic being debated.
Can you take the group ahead if it is stuck at one point?
Can you take it in a fresh and more relevant direction?
The last implication is that you must be clearly seen to be attempting to build a consensus.
Gaining support or influencing colleagues is the mantra adopted by many a successful Business Leaders.
Nobody expects a group of ten intelligent, assertive people, all with different points of view on a controversial subject to actually achieve a consensus. But what matters is "Did you make attempts to build a consensus?"
The reason why an attempt to build a consensus is important is because in most work situations you will have to work with people in a team, accept joint responsibilities and take decisions as a group.You must demonstrate the fact that you are capable and inclined to work as part of a team.

Standard HR Questions

2008-07-19T21:35:00.001+05:30

Fifty Standard Interview Questions

It is not enough to have solid answers only for the above questions. You need to be prepared for the full spectrum of questions that may be presented. For further practice, make sure you go through the required mock interview (see the "Competitive Interview Prep" Section) and for further review, look at some of the following questions:

Tell me about yourself.

What do you want to do with your life?

Do you have any actual work experience?

How would you describe your ideal job?

Why did you choose this career?

When did you decide on this career?

What goals do you have in your career?

How do you plan to achieve these goals?

How do you evaluate success?

Describe a situation in which you were successful.

What do you think it takes to be successful in this career?

What accomplishments have given you the most satisfaction in your life?

If you had to live your life over again, what would you change?

How much money do you need to make to be happy?

What kind of salary are you looking for?

Don't just read these questions--practice and rehearse the answers. Don't let the company interview be the first time you have actually formulated an answer in spoken words. It is not enough to think about them in your head--practice! Sit down with a friend, a significant other, or your roommate (an especially effective critic, given the amount of preparation to date) and go through all of the questions. Make the most of every single interview opportunity by being fully prepared!

The function of PAD (Packet Assembler Disassembler) is described in a document known as X.3. The standard protocol has been defined between the terminal and the PAD, called X.28; another standard protocol exists between hte PAD and the network, called X.29. Together, these three recommendations are often called "triple X"

7. What is frame relay, in which layer it comes?

10. What is redirector?
Redirector is software that intercepts file or prints I/O requests and translates them into network requests. This comes under presentation layer.

11. What is NETBIOS and NETBEUI?
NETBIOS is a programming interface that allows I/O requests to be sent to and received from a remote computer and it hides the networking hardware from applications.
NETBEUI is NetBIOS extended user interface. A transport protocol designed by microsoft and IBM for the use on small subnets.

12. What is RAID?
A method for providing fault tolerance by using multiple hard disk drives.

13. What is passive topology?
When the computers on the network simply listen and receive the signal, they are referred to as passive because they don’t amplify the signal in any way. Example for passive topology - linear bus.

14. What is Brouter?
Hybrid devices that combine the features of both bridges and routers.

15. What is cladding?
A layer of a glass surrounding the center fiber of glass inside a fiber-optic cable.

16. What is point-to-point protocol
A communications protocol used to connect computers to remote networking services including Internet service providers.

17. How Gateway is different from Routers?
A gateway operates at the upper levels of the OSI model and translates information between two completely different network architectures or data formats

18. What is attenuation?
The degeneration of a signal over distance on a network cable is called attenuation.

19. What is MAC address?
The address for a device as it is identified at the Media Access Control (MAC) layer in the network architecture. MAC address is usually stored in ROM on the network adapter card and is unique.

20. Difference between bit rate and baud rate.
Bit rate is the number of bits transmitted during one second whereas baud rate refers to the number of signal units per second that are required to represent those bits.
baud rate = bit rate / N
where N is no-of-bits represented by each signal shift.

21. What is Bandwidth?
Every line has an upper limit and a lower limit on the frequency of signals it can carry. This limited range is called the bandwidth.

22. What are the types of Transmission media?
Signals are usually transmitted over some transmission media that are broadly classified in to two categories.
a) Guided Media:
These are those that provide a conduit from one device to another that include twisted-pair, coaxial cable and fiber-optic cable. A signal traveling along any of these media is directed and is contained by the physical limits of the medium. Twisted-pair and coaxial cable use metallic that accept and transport signals in the form of electrical current. Optical fiber is a glass or plastic cable that accepts and transports signals in the form of light.
b) Unguided Media:
This is the wireless media that transport electromagnetic waves without using a physical conductor. Signals are broadcast either through air. This is done through radio communication, satellite communication and cellular telephony.

23. What is Project 802?
It is a project started by IEEE to set standards to enable intercommunication between equipment from a variety of manufacturers. It is a way for specifying functions of the physical layer, the data link layer and to some extent the network layer to allow for interconnectivity of major LAN
protocols.
It consists of the following:
 802.1 is an internetworking standard for compatibility of different LANs and MANs across protocols.
 802.2 Logical link control (LLC) is the upper sublayer of the data link layer which is non-architecture-specific, that is remains the same for all IEEE-defined LANs.
 Media access control (MAC) is the lower sublayer of the data link layer that contains some distinct modules each carrying proprietary information specific to the LAN product being used. The modules are Ethernet LAN (802.3), Token ring LAN (802.4), Token bus LAN (802.5).
 802.6 is distributed queue dual bus (DQDB) designed to be used in MANs.

24. What is Protocol Data Unit?
The data unit in the LLC level is called the protocol data unit (PDU). The PDU contains of four fields a destination service access point (DSAP), a source service access point (SSAP), a control field and an information field. DSAP, SSAP are addresses used by the LLC to identify the protocol stacks on the receiving and sending machines that are generating and using the data. The control field specifies whether the PDU frame is a information frame (I - frame) or a supervisory frame (S - frame) or a unnumbered frame (U - frame).

25. What are the different type of networking / internetworking devices?
Repeater:
Also called a regenerator, it is an electronic device that operates only at physical layer. It receives the signal in the network before it becomes weak, regenerates the original bit pattern and puts the refreshed copy back in to the link.
Bridges:
These operate both in the physical and data link layers of LANs of same type. They divide a larger network in to smaller segments. They contain logic that allow them to keep the traffic for each segment separate and thus are repeaters that relay a frame only the side of the segment containing the intended recipent and control congestion.
Routers:
They relay packets among multiple interconnected networks (i.e. LANs of different type). They operate in the physical, data link and network layers. They contain software that enable them to determine which of the several possible paths is the best for a particular transmission.
Gateways:
They relay packets among networks that have different protocols (e.g. between a LAN and a WAN). They accept a packet formatted for one protocol and convert it to a packet formatted for another protocol before forwarding it. They operate in all seven layers of the OSI model.

26. What is ICMP?
ICMP is Internet Control Message Protocol, a network layer protocol of the TCP/IP suite used by hosts and gateways to send notification of datagram problems back to the sender. It uses the echo test / reply to test whether a destination is reachable and responding. It also handles both control and error messages.

27. What are the data units at different layers of the TCP / IP protocol suite?
The data unit created at the application layer is called a message, at the transport layer the data unit created is called either a segment or an user datagram, at the network layer the data unit created is called the datagram, at the data link layer the datagram is encapsulated in to a frame and finally transmitted as signals along the transmission media.

28. What is difference between ARP and RARP?
The address resolution protocol (ARP) is used to associate the 32 bit IP address with the 48 bit physical address, used by a host or a router to find the physical address of another host on its network by sending a ARP query packet that includes the IP address of the receiver.
The reverse address resolution protocol (RARP) allows a host to discover its Internet address when it knows only its physical address.

29. What is the minimum and maximum length of the header in the TCP segment and IP datagram?
The header should have a minimum length of 20 bytes and can have a maximum length of 60 bytes.

30. What is the range of addresses in the classes of internet addresses?
Class A 0.0.0.0 - 127.255.255.255
Class B 128.0.0.0 - 191.255.255.255
Class C 192.0.0.0 - 223.255.255.255

Class E 240.0.0.0 - 247.255.255.255

31. What is the difference between TFTP and FTP application layer protocols?
The Trivial File Transfer Protocol (TFTP) allows a local host to obtain files from a remote host but does not provide reliability or security. It uses the fundamental packet delivery services offered by UDP.
The File Transfer Protocol (FTP) is the standard mechanism provided by TCP / IP for copying a file from one host to another. It uses the services offer by TCP and so is reliable and secure. It establishes two connections (virtual circuits) between the hosts, one for data transfer and another for control information.

32. What are major types of networks and explain?
 Server-based network
 Peer-to-peer network
Peer-to-peer network, computers can act as both servers sharing resources and as clients using the resources.
Server-based networks provide centralized control of network resources and rely on server computers to provide security and network administration

33. What are the important topologies for networks?
 BUS topology:
In this each computer is directly connected to primary network cable in a single line.
Advantages:
Inexpensive, easy to install, simple to understand, easy to extend.

Advantages:
All computers have equal access to network media, installation can be simple, and signal does not degrade as much as in other topologies because each computer regenerates it.

34. What is mesh network?
A network in which there are multiple network links between computers to provide multiple paths for data to travel.

35. What is difference between baseband and broadband transmission?
In a baseband transmission, the entire bandwidth of the cable is consumed by a single signal. In broadband transmission, signals are sent on multiple frequencies, allowing multiple signals to be sent simultaneously.

36. Explain 5-4-3 rule?
In a Ethernet network, between any two points on the network ,there can be no more than five network segments or four repeaters, and of those five segments only three of segments can be populated.

37. What MAU?

Virtual channel is normally a connection from one source to one destination, although multicast connections are also permitted. The other name for virtual channel is virtual circuit.

42. What is virtual path?
Along any transmission path from a given source to a given destination, a group of virtual circuits can be grouped together into what is called path.

43. What is packet filter?
Packet filter is a standard router equipped with some extra functionality. The extra functionality allows every incoming or outgoing packet to be inspected. Packets meeting some criterion are forwarded normally. Those that fail the test are dropped.

44. What is traffic shaping?
One of the main causes of congestion is that traffic is often busy. If hosts could be made to transmit at a uniform rate, congestion would be less common. Another open loop method to help manage congestion is forcing the packet to be transmitted at a more predictable rate. This is called traffic shaping.

45. What is multicast routing?
Sending a message to a group is called multicasting, and its routing algorithm is called multicast routing.

46. What is region?
When hierarchical routing is used, the routers are divided into what we will call regions, with each router knowing all the details about how to route packets to destinations within its own region, but knowing nothing about the internal structure of other regions.

47. What is silly window syndrome?
It is a problem that can ruin TCP performance. This problem occurs when data are passed to the sending TCP entity in large blocks, but an interactive application on the receiving side reads 1 byte at a time.

48. What are Digrams and Trigrams?

Operating Systems

2008-07-17T14:41:00.001+05:30

Following are a few basic questions that cover the essentials of OS:

1.Explain the concept of Reentrancy.
It is a useful, memory-saving technique for multiprogrammed timesharing systems. A Reentrant Procedure is one in which multiple users can share a single copy of a program during the same period. Reentrancy has 2 key aspects: The program code cannot modify itself, and the local data for each user process must be stored separately. Thus, the permanent part is the code, and the temporary part is the pointer back to the calling program and local variables used by that program. Each execution instance is called activation. It executes the code in the permanent part, but has its own copy of local variables/parameters. The temporary part associated with each activation is the activation record. Generally, the activation record is kept on the stack.
Note: A reentrant procedure can be interrupted and called by an interrupting program, and still execute correctly on returning to the procedure.

2.Explain Belady's Anomaly.
Also called FIFO anomaly. Usually, on increasing the number of frames allocated to a process' virtual memory, the process execution is faster, because fewer page faults occur. Sometimes, the reverse happens, i.e., the execution time increases even when more frames are allocated to the process. This is Belady's Anomaly. This is true for certain page reference patterns.

3.What is a binary semaphore? What is its use?
A binary semaphore is one, which takes only 0 and 1 as values. They are used to implement mutual exclusion and synchronize concurrent processes.

4.What is thrashing?
It is a phenomenon in virtual memory schemes when the processor spends most of its time swapping pages, rather than executing instructions. This is due to an inordinate number of page faults.

5.List the Coffman's conditions that lead to a deadlock.
a.Mutual Exclusion: Only one process may use a critical resource at a time.
b.Hold & Wait: A process may be allocated some resources while waiting for others.
c.No Pre-emption: No resource can be forcible removed from a process holding it.
d.Circular Wait: A closed chain of processes exist such that each process holds at least one resource needed by another process in the chain.

6.What are short-, long- and medium-term scheduling?
Long term scheduler determines which programs are admitted to the system for processing. It controls the degree of multiprogramming. Once admitted, a job becomes a process.
Medium term scheduling is part of the swapping function. This relates to processes that are in a blocked or suspended state. They are swapped out of real-memory until they are ready to execute. The swapping-in decision is based on memory-management criteria.
Short term scheduler, also know as a dispatcher executes most frequently, and makes the finest-grained decision of which process should execute next. This scheduler is invoked whenever an event occurs. It may lead to interruption of one process by preemption.

7.What are turnaround time and response time?
Turnaround time is the interval between the submission of a job and its completion. Response time is the interval between submission of a request, and the first response to that request.

8.What are the typical elements of a process image?
 User data: Modifiable part of user space. May include program data, user stack area, and programs that may be modified.
 User program: The instructions to be executed.
 System Stack: Each process has one or more LIFO stacks associated with it. Used to store parameters and calling addresses for procedure and system calls.
 Process control Block (PCB): Info needed by the OS to control processes.

9.What is the Translation Lookaside Buffer (TLB)?
In a cached system, the base addresses of the last few referenced pages is maintained in registers called the TLB that aids in faster lookup. TLB contains those page-table entries that have been most recently used. Normally, each virtual memory reference causes 2 physical memory accesses-- one to fetch appropriate page-table entry, and one to fetch the desired data. Using TLB in-between, this is reduced to just one physical memory access in cases of TLB-hit.

10.What is the resident set and working set of a process?
Resident set is that portion of the process image that is actually in real-memory at a particular instant. Working set is that subset of resident set that is actually needed for execution. (Relate this to the variable-window size method for swapping techniques.)

11.When is a system in safe state?
The set of dispatchable processes is in a safe state if there exists at least one temporal order in which all processes can be run to completion without resulting in a deadlock.

12.What is cycle stealing?
We encounter cycle stealing in the context of Direct Memory Access (DMA). Either the DMA controller can use the data bus when the CPU does not need it, or it may force the CPU to temporarily suspend operation. The latter technique is called cycle stealing. Note that cycle stealing can be done only at specific break points in an instruction cycle.

13.What is meant by arm-stickiness?
If one or a few processes have a high access rate to data on one track of a storage disk, then they may monopolize the device by repeated requests to that track. This generally happens with most common device scheduling algorithms (LIFO, SSTF, C-SCAN, etc). High-density multisurface disks are more likely to be affected by this than low density ones.

14.What are the stipulations of C2 level security?
C2 level security provides for:
 Discretionary Access Control
 Identification and Authentication
 Auditing
 Resource reuse

15.What is busy waiting?
The repeated execution of a loop of code while waiting for an event to occur is called busy-waiting. The CPU is not engaged in any real productive activity during this period, and the process does not progress toward completion.

16.Explain the popular multiprocessor thread-scheduling strategies.
 Load Sharing: Processes are not assigned to a particular processor. A global queue of threads is maintained. Each processor, when idle, selects a thread from this queue. Note that load balancing refers to a scheme where work is allocated to processors on a more permanent basis.
 Gang Scheduling: A set of related threads is scheduled to run on a set of processors at the same time, on a 1-to-1 basis. Closely related threads / processes may be scheduled this way to reduce synchronization blocking, and minimize process switching. Group scheduling predated this strategy.
 Dedicated processor assignment: Provides implicit scheduling defined by assignment of threads to processors. For the duration of program execution, each program is allocated a set of processors equal in number to the number of threads in the program. Processors are chosen from the available pool.
 Dynamic scheduling: The number of thread in a program can be altered during the course of execution.

17.When does the condition 'rendezvous' arise?
In message passing, it is the condition in which, both, the sender and receiver are blocked until the message is delivered.

18.What is a trap and trapdoor?
Trapdoor is a secret undocumented entry point into a program used to grant access without normal methods of access authentication. A trap is a software interrupt, usually the result of an error condition.

19.What are local and global page replacements?
Local replacement means that an incoming page is brought in only to the relevant process' address space. Global replacement policy allows any page frame from any process to be replaced. The latter is applicable to variable partitions model only.

20.Define latency, transfer and seek time with respect to disk I/O.
Seek time is the time required to move the disk arm to the required track. Rotational delay or latency is the time it takes for the beginning of the required sector to reach the head. Sum of seek time (if any) and latency is the access time. Time taken to actually transfer a span of data is transfer time.

21.Describe the Buddy system of memory allocation.
Free memory is maintained in linked lists, each of equal sized blocks. Any such block is of size 2^k. When some memory is required by a process, the block size of next higher order is chosen, and broken into two. Note that the two such pieces differ in address only in their kth bit. Such pieces are called buddies. When any used block is freed, the OS checks to see if its buddy is also free. If so, it is rejoined, and put into the original free-block linked-list.

22.What is time-stamping?
It is a technique proposed by Lamport, used to order events in a distributed system without the use of clocks. This scheme is intended to order events consisting of the transmission of messages. Each system 'i' in the network maintains a counter Ci. Every time a system transmits a message, it increments its counter by 1 and attaches the time-stamp Ti to the message. When a message is received, the receiving system 'j' sets its counter Cj to 1 more than the maximum of its current value and the incoming time-stamp Ti. At each site, the ordering of messages is determined by the following rules: For messages x from site i and y from site j, x precedes y if one of the following conditions holds....(a) if Ti
23.How are the wait/signal operations for monitor different from those for semaphores?
If a process in a monitor signal and no task is waiting on the condition variable, the signal is lost. So this allows easier program design. Whereas in semaphores, every operation affects the value of the semaphore, so the wait and signal operations should be perfectly balanced in the program.

24.In the context of memory management, what are placement and replacement algorithms?
Placement algorithms determine where in available real-memory to load a program. Common methods are first-fit, next-fit, best-fit. Replacement algorithms are used when memory is full, and one process (or part of a process) needs to be swapped out to accommodate a new program. The replacement algorithm determines which are the partitions to be swapped out.

25.In loading programs into memory, what is the difference between load-time dynamic linking and run-time dynamic linking?
For load-time dynamic linking: Load module to be loaded is read into memory. Any reference to a target external module causes that module to be loaded and the references are updated to a relative address from the start base address of the application module.
With run-time dynamic loading: Some of the linking is postponed until actual reference during execution. Then the correct module is loaded and linked.

26.What are demand- and pre-paging?
With demand paging, a page is brought into memory only when a location on that page is actually referenced during execution. With pre-paging, pages other than the one demanded by a page fault are brought in. The selection of such pages is done based on common access patterns, especially for secondary memory devices.

27.Paging a memory management function, while multiprogramming a processor management function, are the two interdependent?
Yes.

28.What is page cannibalizing?
Page swapping or page replacements are called page cannibalizing.

32.What are the key object oriented concepts used by Windows NT?
 Encapsulation
 Object class and instance

33.Is Windows NT a full blown object oriented operating system? Give reasons.
No Windows NT is not so, because its not implemented in object oriented language and the data structures reside within one executive component and are not represented as objects and it does not support object oriented capabilities .

34.What is a drawback of MVT?
It does not have the features like
 ability to support multiple processors
 virtual storage
 source level debugging

35.What is process spawning?
When the OS at the explicit request of another process creates a process, this action is called process spawning.

36.How many jobs can be run concurrently on MVT?
15 jobs

37.List out some reasons for process termination.
 Normal completion
 Time limit exceeded
 Memory unavailable
 Bounds violation
 Protection error
 Arithmetic error
 Time overrun
 I/O failure
 Invalid instruction
 Privileged instruction
 Data misuse
 Operator or OS intervention
 Parent termination.

38.What are the reasons for process suspension?
 swapping
 interactive user request
 timing
 parent process request

39.What is process migration?

40.what is mutant?
In Windows NT a mutant provides kernel mode or user mode mutual exclusion with the notion of ownership.

41.What is an idle thread?
The special thread a dispatcher will execute when no ready thread is found.

42.What is FtDisk?
It is a fault tolerance disk driver for Windows NT.

43.What are the possible threads a thread can have?
 Ready
 Standby
 Running
 Waiting
 Transition
 Terminated.

44.What are rings in Windows NT?

46.What are the sub-components of I/O manager in Windows NT?
 Network redirector/ Server
 Cache manager.
 File systems
 Network driver
 Device driver

47.What are DDks? Name an operating system that includes this feature.
