Question

A network interface port has collision detection and carrier sensing enabled on a shared twisted-pair network. From this statement, what is known about the network interface port

Answer 1

Answer:

This is an Ethernet port operating at half duplex.

Explanation:

• This port can just send data in uni direction which means it cannot send and receive data packets at the same time.
• The nodes in the network communicates with the switch and not with each other directly.
• The network interface port has collision detection and carrier sensing enables which helps in detecting the collisions.
• These network interface ports utilize twisted pair network cables
• However Ethernet ports at half duplex are not being used anymore.

Answer 2

Answer:

This is an Ethernet port operating at half duplex.

Explanation:

Modern Ethernet networks built with switches and full-duplex connections no longer utilize CSMA/CD. CSMA/CD is only used in obsolete shared media Ethernet (which uses repeater or hub).
