ISRO | ISRO CS 2013 | Question 38

  • Last Updated : 15 May, 2018

Ethernet layer-2 switch is a network element type which gives
(A) different collision domain and same broadcast domain
(B) different collision domain and different broadcast domain
(C) same collision domain and same broadcast domain
(D) same collision domain and different broadcast domain


Answer: (A)

Explanation: A switch is a multi port bridge with a buffer and a design that can boost its efficiency (large number of ports imply less traffic) and performance. Switch can perform error checking before forwarding data, that makes it very efficient as it does not forward packets that have errors and forward good packets selectively to correct port only. In other words, switch divides collision domain of hosts, but broadcast domain remains same.

Option (A) is correct.
