What is network interface cards?

A network interface card (NIC) is a hardware component that allows a computer to connect to a network. It provides a physical connection to the network medium (e.g., Ethernet cable, Wi-Fi) and enables the computer to send and receive data over the network. NICs handle the low-level communication protocols required for network communication. They are commonly used in desktops, laptops, servers, and other network-enabled devices.
