Q1.  What do you mean by addressing modes? List the different types of addressing modes. 3+7

Answer. Addressing Modes

In general, a program operates on data that reside in the computer’s memory. These data can be organized in a variety of ways. If we want to keep track of students’ names, we can write them in a list. If we want to associate information with each name, for example to record telephone numbers or marks in various courses, we may organize this

Q1. Write a note on replacement algorithms. 10

Answer. When a new block is to be  brought into the cache and all the positions that it may occupy are full, then the cache controller must decide which of the old blocks to overwrite. Because the programs usually stay in localized areas for a reasonable period of time, there is high probability that the blocks that have been referenced recently will be

Q2. Explain the concept of coprocessor. Also explain its functions. 4+6

Answer. Coprocessor

Coprocessor is a relatively new concept in the area of multiprocessing. A coprocessor refers to a computer processor which is utilized as an addition to the functions of the cpu (the primary processor). A coprocessor is also known as a math processor or a numeric processor. It is capable of carrying out large amount of computations, thereby

Q3. How CPU responds to an interrupt? 10

Answer. The CPU checks periodically to determine if an interrupt signal is pending. This check is usually done at the end of each instruction, although some modern machines allow for interrupts to be checked for several times during the execution of very long instructions. When the CPU detects an interrupt, it then saves its current state (at least the PC

Q1 Discuss the advantages and disadvantages of oral communication. Write a short note on the improvement of oral communication. 5+5=10

Answer. Advantages of oral communication:-

In oral communication there is a possibility of immediate response. This makes speedy interaction and immediate feedback possible. This is the biggest advantage of oral communication.

Another advantage is that the speaker can observe the listener's reaction to what is being stated.

Time saving: When action is

Q2. What is “this pointer” in C++? What are the features of “this pointer”? [3+7]

Answer. The pointer is used as a pointer to the class object instance by the member function. The address of the class instance is passed as an implicit parameter to the member functions. The sample below, in this section shows how to use it. It is common knowledge that C++ keeps only one copy of each member function

Q1. What is Polymorphism? What are the different types of Polymorphism? 3+7

Answer. Polymorphism means same content but different forms. In C++, polymorphism enables the same program code calling different functions of different classes. Imagine a situation where you would like to create a class shape and derive classes such as rectangle, circle, triangle etc. Let us suppose each of the classes has a member function draw() that causes the object to be drawn on the screen. You would like to write a common code as

Q2. Explain sequence containers. 10
