geographically dispersed may need to
become so called Wide Area Network (WAN).
Ethernet Technologies
More than 80 percent of all Local Area networks are
installed with Ethernet.
Electronic Engineers (IEEE) define the standard of
Ethernet as IEEE 802.3. The IEEE 802.3 provides rules
for configuring Ethernet LANs, specifies how elements
should interact with one another, and different types of
media that can be used, as well as data rate (10Mbps) of
Ethernet. Ethernet supports just about all kinds of popular
network protocols. It is one of the most ideal networking
technologies today.
Fast Ethernet
For networks that need higher transmission speeds, IEEE
has also established the standard 802.3u, which raises the
Ethernet speed limit from 10 Mbps to 100 Mbps. This
allows a network device to transmit data through media
such as category 5 UTP (Unshielded Twisted Pair) cable
or fiber optic cable at the rate of 100 Mbps instead of 10
Mbps. A number of other high-speed LAN technologies
are also available for high bandwidth and good client
server response time. However, Fast Ethernet offers the
best solution that provides smooth migration from 10Base-
T technology to 100 Base-TX. It requires only minimal
changes with existing cabling infrastructure. Fast Ethernet
and its successors have been said to be the most cost
