What is Ethernet?
Ethernet
A network technology that enables computers and devices to communicate with each other over a wired connection. It uses cables and switches to send data packets efficiently, making it a fundamental part of local area networks (LANs).
Overview
Ethernet is a widely used technology for connecting devices in a local area network (LAN). It allows computers, printers, and other devices to communicate by sending data packets through cables. This technology works by using a protocol that defines how data is formatted and transmitted, ensuring that devices can understand each other despite being from different manufacturers. Ethernet operates through a system of cables and switches that connect devices within a limited area, such as a home or office. When a device wants to send data, it breaks the information into smaller packets, attaches a header with the destination address, and sends it over the network. The switches then direct these packets to their intended destination, allowing for efficient communication between devices. This technology matters because it provides a reliable and fast way to connect multiple devices, enabling activities like file sharing, internet access, and streaming. For example, in an office setting, Ethernet allows employees to share documents and access shared resources quickly, enhancing productivity and collaboration.
