Intro to Computer Networks

Question 1

What is a Local Area Network (LAN)?

Answer 1

Network of users that share computer resources in a limited area.

Question 2

Define Protocol

Answer 2

Set of rules established for users to exchange information.

Question 3

Define Topology

Answer 3

Architecture of a network.

Question 4

What are the most common architectures for LANs?

Answer 4

Ring, Bus, Star

Question 5

What is a token ring topology?

Answer 5

A network topology configured in a logical ring that complements the token passing protocol.

Question 6

What is token passing?

Answer 6

A technique where an electrical token circulates around a network— control of the token enables the user to gain access to the network.

Question 7

What is IEEE?

Answer 7

Institute of Electrical and Electronics Engineers, one of the major standards-setting bodies for technological development.

Question 8

How does a deterministic network work?

Answer 8

Access to the network is provided at fixed time intervals, ensuring access for transmissions.

Question 9

What are disadvantages of a token ring system?

Answer 9

1. If an error changes the token pattern, it can cause the token to stop circulating.
2. Ring networks rely on each system to pass the data to the next user. If a system fails, data traffic can cease.
3. If any system maintenance is required such as adding a system to the ring or replacing a system, the token ring path must be temporarily broken.
