"Switches break up _______________ domains and routers break up _____________ domains."
mel-nik [20]

Answer:

Switches break up collision domains and routers break up broadcast domains.

Explanation:

  • Collision domain depicts the part within a network where a collision can happen.
  • Collision occurs when two hosts transmit data packet at the same time within a network. Theses packets collide and the hosts have to resend the data after some time.
  • Too many collisions can result in slow traffic speed and can effect network performance.
  • So switches break up collision domains between the devices on a network and each port in a switch depicts a collision domain. This reduces the chance of packet collisions between the devices or hosts.
  • When data is to be sent to a host, the switch keeps that data frame and waits for availability of the destination host before sending the data frame.
  • Moreover full duplex switch mode there is not chance of collision as the transmitting path on one host is the receiving path on other host.
  • Broadcast domain contains all the hosts that can reach each other at the Data Link layer via broadcast.
  • Routers break up broadcast domains as routers contain separate broadcast domains for each interface.
  • Routers do not forward broadcasts from one broadcast domain to other and drop the packet when they detect a broadcast address.
