Computer networks colloison domain

Question

What is number of colloision domains in following devices with x-interface???

A) Switch

B) Hub

C) Router

D) Repeater

E) Bridge

E) Gateway

Answer 1

Here we need to think in terms of collision domain separator for each of the cases..

A) Switch is a collision domain separator as it uses lookup table..Hence no of collision domains = no of interfaces = x

B) Hub is not a  collision domain separator..Hence no of collision domains = 1

C) Router is a collision domain separator as it uses routing table..Hence no of collision domains = no of interfaces = x

D) Repeater is a 2 port device only used to prevent attenuation of signal..Hence no of collision domain = 2(no of interfaces)

E) Bridge is an enhanced form of switch only..Hence no of collision domains = no of interfaces = x

F) Same with gateway also as it is multiprotocol switch..
