5. Another approach to pushing beyond the limits of Ethernet is the development of Switching technology A switch works in the MAC address level bridging multiple Ethernet segments to prevent unnecessary network traffic from passing one another In a properly subdivided switched LAN the net result is a full and transparent bandwidth for each segment Switched Ethernet vs Legacy Ethernet is analogous to using private telephone lines vs party lines By connecting to a switched port each Ethernet segment has dynamic full performance or wire speed Therefore a switch effectively splits a physical shared access LAN into bridged multiple LAN segments Each segment supports a workgroup and even provides a dedicated connection to a desktop server The outcome is a multiplication of the overall available bandwidth and a more predictable performance under heavy network loads 10 100 Switching Technology Just as 100Base T is an extension of the existing 10Base T technology 10 100 Switching is merely an extension of 10Base T Switching The 10 100 Switch provides not only the 10 100Mbps high speed transmission rate per segment but it also bridges 10Base T and 100Base T into a harmonious network Combining Fast Ethernet and Switching technologies the 10 100 Switch provides enough bandwidth to satisfy the most demanding workgroups as well as a high speed backbone link Benefits of Switching From the technical point of view Ethernet switc
