Description: Wired Ethernet is a commonly used wired networking technology for local area networks (LANs). It is based on a set of standards that define how data is transmitted over cables, allowing the interconnection of devices such as computers, printers, and servers. Ethernet uses a packet system to send information, ensuring efficient and reliable communication. Ethernet cables, which can be twisted pair, coaxial, or fiber optic, are essential for establishing stable and fast connections. This technology is known for its high transmission speeds, which can reach up to 100 Gbps in the most advanced versions, and its ability to support multiple devices on the same network. Additionally, Ethernet is scalable, meaning it can be easily adapted to different network sizes, from small offices to large data centers. Its simplicity in installation and maintenance, along with its robustness, has made it a standard in the telecommunications and computing industry, being the preferred option for most network implementations in both business and home environments.
History: Ethernet was developed in 1973 by Robert Metcalfe and his team at Xerox PARC as a way to connect computers in a local network. Initially, it used coaxial cable and operated at speeds of 2.94 Mbps. Over the years, Ethernet has evolved significantly, with the introduction of standards such as 10BASE-T, 100BASE-TX, and 1000BASE-T, which have increased transmission speeds and improved efficiency. In 1983, Ethernet was standardized by the Institute of Electrical and Electronics Engineers (IEEE) under the 802.3 standard, which solidified its use in the industry.
Uses: Ethernet is primarily used in local area networks (LANs) to connect computers, printers, servers, and other devices. It is common in business environments where a stable and fast connection is required for data transfer. It is also used in home networks to connect devices such as routers, gaming consoles, and entertainment systems. Additionally, Ethernet is employed in data centers and telecommunications infrastructure to ensure efficient communication between servers and storage devices.
Examples: A practical example of wired Ethernet is connecting a desktop computer to a router using an Ethernet cable, allowing access to the Internet and communication with other devices on the local network. Another example is the use of Ethernet in a business environment, where multiple computers and servers are interconnected through an Ethernet switch, facilitating file transfer and collaboration among employees.
