stackable hubs to increase the total number ports within each collision domain.
A switch uses store and forwarding technology to transfer data between collision domains at the MAC address level of the
Ethernet protocol. This means that data is transferred only to the data's destination collision domain. The data is not
transferred to other collision domains, which allows your total LAN capacity to be increased without the need to invest in new
media infrastructure.
By creating separate collision domains and communicating between them, a switch allows you to overcome the two-hub limit of
Fast Ethernet topology.
You can also use a switch to dedicate a full 100Mbps line to power workstation users and servers.
Switches with bridging technology are ideal for facilitating data transfer between your 10Mbps legacy devices and your new
100Mbps devices.
Switches have lower latencies than the previous generation of network bridges; they use your existing network and do not require
the use of software for installation.
These factors make switches the best solution for most of your LAN congestion problems.

Gigabit Technology

Gigabit Ethernet is an extension to highly successful 10Mbps and IEEE 802.3 Ethernet standards. Offering a raw data bandwidth
of 1000Mbps, Gigabit Ethernet maintains full compatibility with the huge installed base of Ethernet node. The 1000Base-X
Gigabit Ethernet standard was ratified In June 1998 after more than two years of intense effort Within the IEEE 802.3 Ethernet
Committee .The key objective of the 802.3z Gigabit Ethernet Task Force was to develop a Gigabit Ethernet standard that
encompassed the following:
u
Utilized the IEEE 802.3 Ethernet frame formats
u Utilized the CSMA/CD assess method
u Addressed backward compatibility with 10Base-T and 100Base-T technologies
u Allowed half-and full-duplex operation
Gigabit Ethernet common Cabling:
u 1000Base-SX ("S" for short wavelength)
u 1000Base-LX ("L" for long wavelength)
