Wireless networking is often known as WI-FI. It is a way of getting broadband without wires. Wi-Fi allows you to connect several computers at once, anywhere in the house or if you have a laptop, to even use your computer in the garden. You don’t need to install extra phone lines or cables.

Network Interface Cards (NIC)

A network interface controller is a computer hardware component that connects a computer to a computer network. Whereas network interface controllers were commonly implemented on expansion cards that plug into a computer bus, the low cost and ubiquity of the Ethernet standard means that most newer computers have a network interface built into the motherboard.
