What type of device connects multiple computers to the network, but
becomes less efficient as network traffic increases?
❍ A. Switch
❍ B. Hub
❍ C. Repeater
❍ D. Router

A

Hub
A hub operates as a multi-port repeater, where incoming traffic is
repeated to every other port in the hub. If more than one device attempts
to communicate at the same time, these conflicting signals are called a
collision. Each time a collision occurs, the sending devices have to stop
transmitting, wait a random amount of time, and try sending the traffic
again. If many devices are sending large amounts of data, the overall
network efficiency will decrease as the number of collisions increase.
