Detailed explanation-1: -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.
Detailed explanation-2: -Switches are networking devices operating at layer 2 or a data link layer of the OSI model. They connect devices in a network and use packet switching to send, receive or forward data packets or data frames over the network. A switch has many ports, to which computers are plugged in.
Detailed explanation-3: -Router. A router directs data requests from one network to another. Routers examine incoming packets to determine the appropriate destination IP address and then forward the packet to that destination. A router can also enable internet access through its connection to a modem, or as a combined modem-router.
