What is Ethernet?

Ethernet is a standard communication protocol built into software and hardware devices designed to build a local area (LAN). It was designed by Metcalfe Bob in 1973 and, through efforts, d Igital, and ntel and x Erox (for which Metcalfe worked), "Dix" Ethernet has become a standard LAN model.

• two or more computers to be connected together or connected.
• A network interface card (nothing) on ​​every computer.
• Ethernet cable for connecting to each computer.
• A network switch or network hub for direct network operation.
• network software.

Nothing is installed on every computer and a unique address is assigned. The Ethernet cable leads from each to the central switch or hub. A switch or a hub will function as a relay (although they have significant differences in how they process network traffic), receiving and rEžii data packets across LAN. This type of network is therefore created by a communication system that allows data and resources, including printers, fax machines and scanners.

These networks can also be wireless. Rather than using a computer for connecting computers, the wireless uses radio waves for bidirectional communication with a wireless switch or hub. Instead of ethernet ports, wireless, switches and rounds have a small antenna. Wireless networks may be more flexible to use, but also require special security for security configuration.

Alternative technologies include the Passse "Token Ring" protocol designed by IBM and much more recent asynchronous transmission mode (ATM). The ATM allows the device to be connected at a very wide range and creates Wans (wide nets) that behave like Lans. For a cheap network located in Singing LE, however, Ethernet is a well -established standard with solidIt boasts and boasts a reliable network environment for three decades.

Formal designation for standardization of Ethernet protocol is sometimes referred to as IEEE 802.3 . IEEE (Institut of Electrical and Electronics Engineers) proposed in February 1980 a working group - billing the designation [19] 80 2 [ND month] - Standardize network protocols. The third subcommittee worked on taste essentially identical to Ethernet, although there are negligible deviations. As a result, the general use of this term can refer to IEEE 802.3 or DIX.
