NETWORK TOPOLOGIES

A__________ routes the data on a network.

• HUB

• ROUTER

• SWITCH

• NIC

What is network topology?

• The physical placement of network cables.

• The arrangement of nodes in a computer network to enable communication.

• The speed at which data travels through a network.

• The security protocols used to protect network data.

Which of the following accurately describes data transmission in a Bus Topology?

• All data is transmitted over a common transmission medium and can be received by all nodes simultaneously.

• Each node is connected to a central hub, and data travels through the hub.

• Data is transmitted in a circular path, passing through each node sequentially.

• Every node has a direct, dedicated connection to every other node.

How is data transmission managed in a Ring Topology?

• Data is broadcast to all nodes, and the intended recipient claims it.

• Nodes send data directly to their intended recipient, bypassing intermediate nodes.

• Data transmission occurs with the help of a token, and is always unidirectional.

• A central server manages all data flow and directs traffic between nodes.

• Yes

• No

Which of the following is a primary disadvantage of a Ring Topology?

• High security.

• Bidirectional communication.

• A single point of failure can disrupt the entire network.

• Performance improves with increased load.

What is a major drawback of a Star Topology?

• It is difficult to design and implement.

• It lacks centralized administration.

• A failure in the central node affects the entire network.

• It is highly scalable without additional cost.
