Questions and Answers

Explain the benefits of full-duplex communication in networking.

Full-duplex communication increases bandwidth efficiency by allowing both ends of a connection to transmit and receive data simultaneously. This results in 100 percent efficiency in both directions, doubling the potential use of the stated bandwidth.

What is the difference between full-duplex and half-duplex communication?

Full-duplex communication allows for bidirectional communication, while half-duplex communication is unidirectional, leading to potential performance issues and collisions.

How are switch ports configured for specific duplex and speed settings?

Switch ports can be manually configured with specific duplex and speed settings using the respective interface configuration commands duplex and speed.

What is the default setting for duplex and speed for switch ports on Cisco Catalyst 2960 and 3560 switches?
