The 10-Mbps Standard Ethernet has gone through several changes before moving to higher data rates. The new designs include:Fast Ethernet:Fast Ethernet Ethernet was designed to compete with LAN protocols such as FDDI or Fiber Channel Channel.IEEE created Fast Ethernet Ethernet under the name 802.3u.Fast Ethernet Ethernet is backward backward-compatible compatible with Standard Standard Ethernet Ethernet, but it can transmit data 10 times faster at a rate of 100 Mbps.The topology of Fast Ethernet is as shown:The goals of fast Ethernet include:Upgrading the data rate to 100 MbpsImproved error detection and correction rates of Ethernet.It is used in networks with Category 5 (Cat-5) copper twisted-pair cable and fiber-optic cable.Keeping the same minimum and maximum frame length.Other designs include:Bridged EthernetSwitched EthernetFull-Duplex EthernetGigabit Ethernet
