What is network hardware?

Network hardware encompasses the physical components required for a computer network to operate. This includes devices such as routers, switches, hubs, network interface cards (NICs), modems, and cables. Routers connect multiple networks, switches manage network traffic within a single network, hubs connect devices in a network, NICs enable devices to connect to a network, and modems modulate and demodulate signals for data transmission over communication channels. These components facilitate communication and data transfer between devices on a network and between networks.
