Question

A topology that involves Tokens.

(a) Star

(b) Ring

(c) Bus

(d) Daisy Chaining

I have been asked this question in class test.

The query is from Network Topologies in portion Data Communications and Computer Networks of Computer Fundamentals

Answer 1

The correct answer is (b) Ring.

In a Ring topology, data is transferred around the network in one direction (or sometimes both, in a bidirectional ring). A "token" is used in this type of network to control access to the network. The token is a special data packet that is passed from one node to another. A node can only send data if it holds the token, preventing data collisions. This method ensures that only one device can transmit at any time, which helps avoid data collisions and manage network traffic efficiently.

Here’s a quick summary of the other topologies:

• (a) Star topology connects all nodes to a central hub or switch, and there’s no "token" involved.
• (c) Bus topology uses a single central cable (the bus) to which all nodes are connected, and it doesn't use tokens for controlling access.
• (d) Daisy Chaining refers to a configuration where devices are connected in a linear sequence, but it doesn’t specifically involve tokens.

Thus, Ring topology is the one that involves tokens.
