A network adapter is usually the only component within a computer for interfacing or connecting with a network. Typically, it is built on a printed circuit board with jumpers that connect it with the computer’s motherboard.
Wireless adapters connect with the network through a built-in or externally connected antenna. Both network adapters support popular LAN protocols such as TCP/IP
Example of usage – “A network adapter for wired networks has an RJ-45 port that uses twisted or untwisted pair cable for network connectivity.”
