ISRO | ISRO CS 2007 | Question 21
An Ethernet hub
(A) functions as a repeater
(B) connects to a digital PBX
(C) connects to a token-ring network
(D) functions as a gateway
Explanation: A Hub is a network hardware device for connecting multiple Ethernet devices together and making them act as a single network segment.
A repeater is an electronic device that receives a signal and re-transmits it. Repeaters are used to extend transmissions so that the signal can cover longer distances or be received on the other side of an obstruction.
An Ethernet Hub or a Repeater Hub also acts as a repeater and regenerates the signal to avoid its loss.
Option (A) is correct.
