The term Ethernet refers to the family of
local-area network (LAN) products covered by
the IEEE 802.3 standard that defines what is
commonly known as the CSMA/CD protocol. Three
data rates are currently defined for operation
over optical fiber and twisted-pair cables:
• 10 Mbps—10Base-T Ethernet
• 100 Mbps—Fast Ethernet
• 1000 Mbps—Gigabit Ethernet
Ethernet has survived as the major LAN technology
(it is currently used for approximately 85 percent
of the world's LAN-connected PCs and workstations)
because its protocol has the following characteristics:
• Is easy to understand, implement, manage,
• Allows low-cost network implementations
• Provides extensive topological flexibility
for network installation
• Guarantees successful interconnection
and operation of standards-compliant products,
regardless of manufacturer
Over short distances, for instance, within a
small geographic area such as a building, you
can create a Local Area Network, which is called
a LAN. It's called a local area network because
we're connecting PCs in just one local location,
an office building for example.
Building a computer network means opening a
world of new opportunities for your business.
It means flexibility, efficiency, and immediate
access to information that will change the way
you work, communicate and serve your customers.

Wireless LANs enable users to establish and
maintain a wireless network connection throughout
or between buildings without the limitations
of wires or cables. At Eitech we are here to
help your business select from a family of wireless
LAN products that combine the mobility and flexibility
users want from a wireless LAN product with
the throughput and security they demand from
a business LAN.
A network that connects a LAN to a LAN across
a large geographic area such as city or country
is called a Wide Area Network or WAN. A WAN
can transmit information by telephone line,
microwave, or satellite.
LANs and WANs are private networks. They interconnect
people inside your organization.
Outside of LANs and WANs is the Internet - an
enormous, public WAN. The Internet links PCs
at universities, research centers, and companies
across the globe.
As networks become more powerful and more businesses
and homes become connected, the Internet serves
as a contact point between your company, your
suppliers, prospects, and customers.
