COMPUTER NETWORKING

Detailed explanation-1: -Answer. 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: -Both Hubs and Switches are network connecting devices. Hubs are basic networking devices that operate at the Physical Layer and they are used to send the data packets to all the connected devices, without any filtration.

Detailed explanation-3: -A Hub is a networking device that allows you to connect multiple PCs to a single network, whereas a Switch connects various devices together on a single computer network. A Hub operates on the physical layer, whereas Switch operates on the data link layer.

Detailed explanation-4: -A network switch (also called switching hub, bridging hub, and, by the IEEE, MAC bridge) is networking hardware that connects devices on a computer network by using packet switching to receive and forward data to the destination device.
