Appendix B - Introduction to LAN
& Ethernet Technologies
As communication and business applications become
increasingly complex, computer networking has evolved
as a very important part of the infrastructure.
Communication systems like Local Area Network (LAN)
evolved into sophisticated, powerful, yet flexible
technology. Among the different types of LAN
technologies, Ethernet represents the best in speed, cost,
ease of installation, and supportability.
LAN
Local Area Network (LAN) technology gave personal
computers the power to share resources of hardware and
software. LAN connects personal computers, file servers,
printers, etc. together within a geographical area, usually
a single building. Multiple, widely dispersed LAN
systems are referred to as a wide area network
(WAN).
Ethernet Technologies
More than 80 percent of all LANs utilize Ethernet
technology. The Institute of Electrical and Electronic
Engineers (IEEE) standardized Ethernet in IEEE 802.3,
which provides for configuration rules, interaction
requirements, types of media, and data rate.
