State the functions of i. Repeater ii. Switch iii. Gateway iv. Bridges
by

1 Answer

Answer :

i) Repeater:

Repeaters are used to take the distorted, weak and corrupt input signal and regenerate this signal at its output. It ensures that the signals are not distorted or weak before it reaches the destination.

It increases the signal strength.

ii) Switch: A switch is a small hardware device that joins multiple computers together within one Local Area Network (LAN). Network switches operate at

Data Link Layer of the OSI model. A switch is device that provides a central connection point for cables from workstations, servers and peripherals.

iii) Gateway: It is a device which connects two different dissimilar networks which has similar function of communication. It is also called as protocol convertor. It works in all layers of OSI model.

iv))Bridge:

A bridge device filters data traffic at a network boundary.

Bridges reduces the amount of traffic on a LAN by dividing it into two segments.

It inspects incoming traffic and decides whether to forward or discard it.

It sends packets between two networks of same type.
