[Fall 2015] ASSIGNMENT
PROGRAM - Master of Science in Information
Technology (MSc IT)
SEMESTER - 2
SUBJECT CODE & NAME - MIT204– Data
Communication & Networking
CREDIT –
4 BK ID - B1389 MAX. MARKS - 60
Q1. List
and explain the major problems in transmission lines.
Answer:
Analog signal
consist of varying a voltage with time to represent an information steam. If
the transmission media were perfectly, the receiver could receive exactly the
same signal that the transmitter sent. But communication lines
2. Explain
the major criteria for a Data Communication Network
Answer:
The major
criteria that a Data Communication Network must meet are:
Performance
Consistency
Reliability
Recovery
Security
1.
Performance
Performance is the defined as the rate of transferring error
free data. It is measured by the Response Time. Response Time is the elasped
time between the end of an inquiry and the beginning of a response. Request a

3. Write
a note on a) 10Base2 b) 10Base- T
Answer:
10Base2:
10BASE2 (also known as cheapernet, thin Ethernet, thinnet,
and thinwire) is a variant of Ethernet that uses thin coaxial cable (RG-58A/U
or similar, as opposed to the thicker RG-8 cable used in 10BASE5 networks),
terminated with BNC connectors. During the mid to late 1980s this was the
dominant 10 Mbit/s Ethernet standard, but due to the immense demand for high
speed networking, the low cost of Category 5
4 List
the properties of Routing algorithm.
Answer:
properties
of Routing algorithm:
·
All packets should reach their destination
(unless prevented by other factors, e.g. congestion).
·
Data transfer should be as quick and efficient as
possible. Using the shortest or fastest route helps achieve this.
·
5 Explain the following
a)
Class A networks
b)
Class B networks [5+5] 10
Answer:
Class A
networks
Each Class A
network address has an 8-bit network-prefix with the highest order bit set to 0
and a seven-bit network number, followed by a 24-bit host-number. Today, it is
no longer considered 'modern' to refer to a Class A network. Class A networks
are now referred to as "/8s" (pronounced "slash eight" or
just "eights")
6.Explain
the following.
a) Open
loop congestion control
b)
Closed loop congestion control
Answer: Open Loop Congestion Control
• In this method,
policies are used to prevent the congestion before it happens.
• Congestion control is handled either by the source or by the destination.
• The
various methods used for open loop congestion control are:
1.
7. Explain
different categories of network security problems
Answer: Network security problems
can be divided roughly into four categories:
1) Secrecy:
2) Authentication
3) Non-repudiation
4) Integrity control
1) Secrecy: It is also called confidentially. It has
to do with keeping information out of hands of unauthorised users.
2) Authentication: It deals with determining who the
destination or recipient is before revealing sensitive
