What is the primary function of a Network Interface Card (NIC)?

The primary function of a Network Interface Card (NIC) is to connect a computer to a network. A NIC acts as the interface between the computer and the network, enabling the computer to communicate with other devices on the same network. It allows data to be transmitted and received over wired or wireless connections, facilitating the exchange of information and network resources.

By providing this crucial connection, the NIC ensures that a computer can access the internet or communicate with other devices within a local area network (LAN), making it an essential component for any device that requires network connectivity. The ability of the NIC to handle network protocols and manage communications makes it vital for various tasks, such as browsing the internet, sharing files, or participating in online communications.
