NIC - GCSE Computer Science Definition

Reviewed by: James Woodhouse

Published

A Network Interface Card (NIC) is a piece of hardware in a computer that allows it to connect to a network, such as the internet or a local area network (LAN). It can be thought of as the computer's gateway to communicate with other computers and devices over the network. The NIC is responsible for sending and receiving data, and it can be either wired, using an Ethernet cable, or wireless, using Wi-Fi. Every NIC has a unique MAC address, which helps identify the device on the network. Understanding how NICs work is important for learning how computers and networks communicate with each other efficiently and securely.
