What is a fast Ethernet?
Fast Ethernet is a set of Ethernet standards for 100 Megabit per second (MBPS) of computer network. Using fast Ethernet, data can be transmitted via pairs of copper or longer optical fiber distances. Its low cost and relatively high speed often make it a good choice for daily network connection. They are often used by desktop and portable computers to communicate with network hubs, routers and switches.
over the beginning of the 90s. High -speed optical technologies, such as distributed fiber data interface, were often too expensive to implement. The institute of electrical and electronic engineers (IEEE) introduced Fast Ethernet as a cheap solution in 1995. Fans originally claimed that this 100 Mbps technology can be used without replacing existing network cables. In fact, many installations had to be re -connected with a newer cable standard to fully supportThe Theater was shown. IEEE 100BASE-T2 and 100BASE-T4 standards have introduced fast Ethernet through twisted paired cables. These standards used the same Cat 3 cables as older 10 Mbps networks. IEEE 100BASE-TX has become the most widespread standard using 5 or better copper cables. Like Cat 3, Cat 5 cables are limited to a maximum length of 328 feet (100 meters) and use the same type of connector.
Four other standards in the IEEE 100base family define 100 Mbps based on optics. Maximum cable length from 1 310 feet (400 meters) to more than 24 miles (40 kilometers). The type of optics and fibers used determines the permissible length and design of the cable.
To help relieve the transition from 10 Mbps to fast Ethernet, many devices have been sold to support both speeds. The so -called network interface cards "10/100", notebook interfaces and hubs can automatically negotiate the highest line speed. Routers, switches and other network devices may also include this ability as well as configuration of time of time.
The term Ethernet Fast is relative to network technology available at the time. In 1995 he operated a regular Ethernet at only 10 Mbps and Fast Ethernet was 10 times faster. Since the end of the 90s, however, the speed of Ethernet has increased significantly. 1 Gigabit per second (GBPS) Etherne - also known as Gigabit Ethernet - was introduced in 1999. This was followed by 10, 40 and 100 gigabit ethernet in 2000.
