A network adapter, also known as a network interface card (NIC), is a crucial component that allows a computer to send and receive data over a local network. Its primary function is to connect a computer to the network, enabling communication and data transfer.
In the past, different types of networks like Token Ring, LocalTalk, and FDDI were used, but nowadays, the term “network adapter” commonly refers to an Ethernet adapter. Additionally, a Wi-Fi adapter can also be considered as a type of network adapter.
Most modern desktop and laptop computers come with built-in Ethernet circuitry, eliminating the need for a separate network adapter. However, in certain cases, such as when a faster Ethernet standard is introduced and not widely supported, high-end computers may require a plug-in network adapter card (NIC).
Ultimately, a network adapter plays a vital role in computer networking by facilitating the transmission and reception of data over a local network, enabling seamless communication and connectivity.
