NETWORKS
What you want . . .
. . . is for all your computers to be
able to:
●Communicate -- send
and receive e-mail, and
participate in
conferences
●Share information --
transfer files among
systems, and get
information from central
databases
●Share resources -- use
shared printers,
scanners, and servers
NETWORKS
The problem is . . .
. . . standalone computers have
no way to talk to each other, so
attempts at communication fail.
NETWORKS
The solution: a local
area network
A local area network (or LAN)
provides connections that tie the
computers together and allow
them to communicate. (The most
common type of local area
network may also be referred to
as an Ethernet LAN or an
Ethernet.)
Local area networks can be
either wired (as shown here) or
wireless. We will look at the
different types in the next few
pages.
NETWORKS
Wired LANs
As the name implies, a wired
LAN connects computers (and
other network devices)
physically, using wires. A typical
LAN uses twisted-pair wiring
(similar to telephone wiring) to
connect each computer to a
central hub. The hub transmits
network communications
between computers.
Wired LANs offer high-speed
communication, as well as
reasonable security and
reliability. In general, however,
they are not as flexible as
wireless LANs.
Most wired LANs conform to the
IEEE 802.3 standard. The most
common wiring schemes use
twisted-pair wiring or thin
coaxial wiring.

DETAIL
Wiring: twisted-pair
The most common wiring used
for LANs is twisted-pair wiring,
similar to the wiring used for
telephones. This wiring connects
the computers or other network
devices to a central hub. The use
of telephone-type wiring makes
it easy for the persons who
administer your telephone
wiring to administer the network
wiring as well.
RJ-45 connectors are used to
connect the twisted-pair wiring
to the computer and to the hub.
The wire for a network can be
graded in a number of
categories; Category 5 wiring is
the most popular grade. Category
5 wiring has superior electrical
characteristics, and we strongly
recommend it for all twisted-pair
networking applications. The
wire grade is usually marked on
the cable jacket.
The equipment for a twisted-pair
LAN commonly operates at a
data rate of either 10 Mbps
(megabits per second) or 100
Mbps. Category 5 wiring is
required for 100-Mbps
operation. A 10-Mbps LAN can
run on either Category 3 or
Category 5 wiring (though we
strongly recommend Category 5).
At either data rate, cables may
extend up to 100 meters (328
feet) from the hub to the
computer.
A twisted-pair network running
at 10 Mbps is called a type
10Base-T network. A twisted-
pair network running at 100
Mbps is called a type 100Base-T
network.
