Network Topology (Suggested solutions)

Answer the following questions about “Bus Topology”

1.  What is “Bus Topology”?

Bus topology uses a common backbone to connect all the network devices in a network in a linear shape. All nodes (file server, workstations, and peripherals) are connected to the linear cable.

2.  How “Bus Network” connected? (Draw the network diagram, describe how it is connected)

Diagram:

Description:
A single cable functions as the shared communication medium for all the devices attached with this cable with an interface connector.

3.  How to send message in a “Bus Network”?

The device, which wants to communicate send the broadcast message to all the devices attached with the shared cable but only the intended recipient actually accepts and process that message.

4.  What is the disadvantage of “Bus Topology”?

The whole network will be down if the backbone is broken.


Answer the following questions about “Ring Topology”

5.  What is “Ring Topology”?

Each node is connected to exactly two other nodes, forming a ring.

6.  How “Ring Network” connected? (Draw the network diagram, describe how it is connected)

Diagram:

Description:
In a ring network, each computer is connected directly to two other computers on the network.

7.  How to send message in a “Ring Network”?

In a ring network, all the communication messages travel in the same directory whether clockwise or anti clockwise.

8.  What is the disadvantage of “Ring Topology”?

The whole network will be down if one of the client computers is down.


Answer the following questions about “Star Topology”

9.  What is “Star Topology”?

A star topology is designed with each node (file server, workstations, and peripherals) connected directly to a central network hub, switch or server.

10.  How “Star Network” connected? (Draw the network diagram, describe how it is connected)

Diagram:

Description:
Each node of the network is connected to a central node.

11.  How to send message in a “Star Network”?

To send a message from one end device to another, the message must be sent via the co-ordinator, which relays the message to the destination.

12.  What is the disadvantage of “Star Topology”?

The whole network will be down if the central node fails.
