Assignment
Set -1
1 What are the criteria for a Data
Communication Network?
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 networks,
2 Explain the 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)
3 Write short notes on 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
staircase

2 What is the need for Protocol
Architecture?
Answer: The architecture of the TCP / IP protocol is the result of
protocol development and experimental packet-switched
3 Write short notes on 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 signa
