THEORY EXAMINATION (SEM–VIII) 2016-17 DATA COMMUNICATION NETWORK

Section A
 

Section A contains short questions that test basic concepts of data communication and networking. Students need to give brief definitions and short explanations related to networking models, protocols, transmission media, and IP addressing.

Example Questions from Section A:

What are the three generations of Ethernet?

What are the desired properties of routing algorithms?

What causes network congestion?

Define socket and its types.

Draw and explain communication model.

What is the relation between bandwidth and bit rate?

What are advantages of optical fiber?

List types of IP addresses.

Define flow control.

Explain types of cryptography.

Section B – Description (with More Questions)

Section B contains medium-length questions that require detailed explanations of networking protocols, routing algorithms, and transmission techniques. Students must explain working of protocols and compare networking methods.

Example Questions from Section B:

Explain Go-Back-N protocol and its limitations.

Describe HDLC frame structure.

Explain TCP transmission policy.

Explain IEEE 802.4 protocol.

Explain distance vector routing algorithm.

Explain leaky bucket algorithm.

Explain TCP header format and connection establishment.

Compare HTTP and FTP protocols.

Explain UDP protocol.

Section C – Description (with More Questions)

Section C contains long and advanced questions that require detailed explanations, derivations, and numerical problem solving. Students must discuss network protocols and perform calculations related to data transmission.

Example Questions from Section C:

Explain Slotted ALOHA and Pure ALOHA with efficiency derivation.

Explain IPv4 frame format and advantages of IPv6.

Describe ATM protocol layers.

Calculate CRC for given data sequence.

Explain OSI protocol hierarchy comparison.
