What Is an Ethernet Network Adapter?
An ethernet network adapter is an essential device for connecting a computer to a network via LAN cables.
Also known as LAN adapters, network cards, or NICs, they convert data sent from the computer into digital signals and enable communication with other devices through LAN cables. The transmitted data is converted into digital signals and processed by the recipient’s adapter.
They are used in various locations such as homes, offices, data centers, and factories. They operate at the data link layer of the OSI reference model, using identification numbers called MAC addresses to communicate. Key features include high-speed data transfer rates, reliable connections, and scalability.
