Explanation:
Detailed explanation-1: -Switches. A switch is a data link layer networking device which connects devices in a network and uses packet switching to send and receive data over the network. Like a hub, a switch also has many ports, to which computers are plugged in.
Detailed explanation-2: -The hub simply takes the pulse it receives and multiplies it – that is, sends it to all other ports. For example, if A sends a frame to B, the hub will send this frame to B, C and D – all ports except A’s port.
