What is Ethernet?
Ethernet is a protocol
that is used over Local Area Network (LAN). Basically
Ethernet is a LAN technology
that is used to communicate information or data between
different computers at 100Mbps and more. 10BASE-T Ethernet
can transmit information up to 100Mbps and Gigabit Ethernet
can transmit information up to 1000 Mbps. Ethernet is based
on bus topology but can also be used in star topology and
uses cables system to transmit information or data, most
common in LAN networks as well as WAN.
Today Ethernet has become
the most popular technology and widely used all over the
world due to its performance, easy to install and maintain.
Ethernet served as the basic for the IEEE 802.3 standard and
work on psychical and application layers. Ethernet uses the
CSMA/CD
(carrier-sense multiple access with collision detection)
technology for access.
In these days Ethernet used
advance mode for data communication called Full-duplex mode.
In Full-duplex mode data can be communicate in both
directions at the same time (send and receive). Because in
past data communication between systems in only one
direction at a time called half-duplex mode. But at the same
time there are some limitations with Ethernet for example,
Distance limitations of UTP cable, Network size limitation
and collisions likely as number of hosts increases.
