Questions & Answers

Q: What is a hub in a network architecture?

A hub acts as a central controller connecting nodes in a network architecture, facilitating data transfer among devices within the network. It serves as a pivotal component for communication between various nodes.

Q: How do broadcast networks differ from switch networks in terms of data transmission?

In a broadcast network, data is broadcast to all network interface units, providing services to all devices. In contrast, switch networks segment data streams, offering more secure and selective data transmission.

Q: What role does the feeder network play in network architectures?

The feeder network between hubs and remote nodes allocates bandwidth for data transmission. It can either provide dedicated bandwidth to each network interface unit or shared bandwidth among multiple units.

Q: How do telephone networks differ from cable networks in terms of infrastructure?

Telephone networks typically use twisted pair copper cables, while cable networks utilize fiber optic cables for data transmission. Both networks offer varying bandwidth capacities and signal processing capabilities.
