A wired network connection uses Ethernet cables to transmit data between different computer devices and connect computers, routers, and switches in a local area network.
Wired networks are speedy and reliable with less risk of data packets loss but the upgrading cost of wired networks is more than that of wireless networks.
Wired networks can be small in which a single router can connect computers in a network and wired networks can also be large in which many routers and switches are used to connect computers.
Wired network the computers are connected to Internet using T1 line or cable modem.
