Answer: Communication Network is set of equipment or say facilities that provide a communication services like to transfer of data between two or more nodes located in any of its geographical point. Example of such networks includes computer networks (LAN/WAN), telephone

2 Elaborate about TCP/IP Protocol Architecture.

Answer: Two protocol architectures have served as the basis for the development of interoperable communications standards: the TCP/IP protocol suite and the Open Systems Interconnection (OSI) reference model. TCP/IP is the most widely used interoperable architecture, and has won the "protocol wars." Although some useful standards have been developed in the

3 Discuss in details about Delta Modulation (DM).

Answer: Delta Modulation (DM)

In delta modulation, an analog input is approximated by a staircase function that moves up or down by one quantization level ᵟ at each sampling interval (TS). An example is shown in figure below, where the

2 Outline the need for a Protocol Architecture.

Answer: The architecture of the TCP / IP protocol is the result of protocol development and experimental packet-switched networks, Apa, developed by the US Department of Defense’s Advanced Research Projects

3 Discuss in details about Pulse Code Modulation (PCM).

Answer: Pulse Code Modulation

Pulse code modulation (PCM) is based on the sampling theorem.

Sampling Theorem: It states that “If a signal f(t) is sampled at regular intervals of time and at a rate higher than twice the highest signal frequency, then the samples contain all the information of the original

SUBJECT CODE & NAME BIT201 – Object Oriented Programming – C++

Assignment Set -1

1 Elaborate about Polymorphism. Survey the different types of Polymorphism.

Answer: Virtual functions in C++ are important to implement the concept of polymorphism. Polymorphism means same content but different forms. In C++, polymorphism enables the same program code calling

2 Discuss the following functions of file operations

a) tellg()

b) seekp()

c) ignore()

d) getline()

Answer: A. tellg() – Returns an int type, that shows the current position of the inside-pointer. This one works only when you read a file. Example:

#include <fstream.h>

void main()

3 Discuss in details about sequence containers and different types of it.

Answer: Sequence Containers

There are three types of sequence containers in the STL. These, as their name suggests, store data in linear sequence. They are the

Assignment Set -2

1 Make a detailed comparison between an external variable and an automatic

variable with the help of an example.

Answer: Automatic variables is default variable in C++. All the variables we have created and used in programs are automatic variables. These variables can also be declared by prefixing the keyword auto. One of important characteristics of

2 What is “this pointer” in C++? What are the features of “this pointer”?

Answer: The this 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,

3 Do a detailed survey on destructor.

Answer: Destructors are usually used to deallocate memory and do other cleanup for a class object and its class members when the object is destroyed. A destructor is called for a class object when that object passes out of scope or is explicitly deleted. A destructor is a member function with the same name as its

SUBJECT CODE & NAME BIT202 – Basic Mathematics

Assignment Set -1

1 Integrate the following w.r.t. x

i) x √(x + a)

ii) x /√(a + bx)

Answer: a) x √(x + a)

∫x√(x+a) dx = I (say)

Put x+a = t^2 so x = t^2

2 If a = cos q + i sin q, 0<q <2p prove that {1+a}/{1-a} = i cot q/2

Answer: i. If a = cos q + i sin q,0 <q < 2p prove that 1+a/1-a = i cot q/2

L.H.S = 1+ cos q + i sin q

1 - cos q - i sin q

= 2 cos^2 q/2

Types of Graphs

Depending upon the vertices and edges and the weight associated to it, graphs can be classified as:

1) Undirected graph: In Undirected

Q2. Describe the following storage allocation:

2. Variable block

Answer:

Fixed block storage allocation

First block storage allocation is the simplest case of dynamic storage allocation. This is the straight forward method in which, all the blocks are of identical in size. The user can decide the

3. What is sorting? Discuss about merge sort with suitable example.

Answer:

Sorting

Sorting is the process of arranging a collection of items in some specified order. The items/records in a file or data structures in memory, consist of one or more fields or members. One of these fields is designated as the "sort key" which means the records will be ordered

Set 2

Q1. Give a detailed report about complexity of algorithm. Explain asymptotic

notations.

Complexity of Algorithm

To compare the efficiency of the algorithms we need some criteria to measure the efficiency. Time and space are two main measures for the efficiency of an algorithm.

Time is the number of time the basic operation is executed. For example in sorting and searching
