Ethernet is a widely used networking technology that enables devices to communicate over a local area network (LAN). It operates using a protocol that defines how data packets are transmitted and received, ensuring reliable and efficient communication between computers, printers, and other devices within a network. Originally developed in the 1970s, Ethernet has evolved through various standards, including Fast Ethernet and Gigabit Ethernet, to support higher speeds and improved performance. Its versatility and scalability make it a popular choice for both home and enterprise networks, facilitating seamless connectivity in today's digital world.
