Q

What is a Local Area Network (LAN)?

A

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

2
Q

Define Protocol

A

Set of rules established for users to exchange information.

3
Q

Define Topology

A

Architecture of a network.

4
Q

What are the most common architectures for LANs?

A

Ring, Bus, Star

5
Q

What is a token ring topology?

A

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

6
Q

What is token passing?

A

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

7
Q

What is IEEE?

A

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

8
Q

How does a deterministic network work?

A

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

9
Q

What are disadvantages of a token ring system?

A
  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.
