Switches, hubs and
NICs are easy to install. Make sure you purchase switches and hubs that
feature installation wizards. These wizards enable you to install them
quickly and without technical expertise. NICs are easy to install and
require no ongoing administration. Many computers and printers come standard
with NICs.
Cabling

Cables are the wires that physically connect your computers, printers and
other devices together and provide the infrastructure upon which your data
will travel across your LAN. The proper cabling, correctly installed, is
essential to an effective and reliable computer network.
There are basically two kinds of cables you can use for your network –
coax and twisted pair. Coax resembles TV wire. It has the benefit of not
requiring a hub and can be used to connect large numbers of computers
together in a single “string.” But this configuration has its drawbacks;
if one computer goes down, the whole network is down. It is also less
flexible than newer twisted-pair cabling and does not support high-speed
technologies.
Twisted pair is the most common type of network cable used today. It
resembles the wire that connects your telephone to the wall jack and its
connector looks like a phone jack as well. Twisted pair cables are low
cost. They allow you to make additions and changes to the network easily,
and can support high-speed technologies such as Fast Ethernet.www.tartoos.com
For investment protection, we strongly recommend that you install cabling
that supports both Ethernet and Fast Ethernet speeds. Typically these are
called 10Base-T or Cat-5 wiring. Cabling is one of the more difficult
parts of your network to upgrade, so it makes good business sense to lay a
foundation that will grow as your network needs do. As your business and
its needs expand, you will be able to upgrade to Fast Ethernet performance
without replacing your network’s cables.
Although the term "network" has many definitions, most people would agree
that networks are collections of two or more connected computers. When
their computers are joined in a network, people can share files and
peripherals such as modems, printers, tape backup drives, or CD-ROM
drives. When networks at multiple locations are connected using services
available from phone companies, people can send e-mail, share links to the
global Internet, or conduct videoconferences in real time with other
remote users.

Every network includes:
-
At least two computers
-
A network interface on
each computer (a device that lets the computer talk to the network),
usually called a network interface card
(NIC) or adapter.
-
A connection medium,
usually a wire or cable, although
wireless communication between
networked computers and peripherals is also possible.
-
Network operating
system software, such as Microsoft Windows 95 or Windows NT, Novell
NetWare, AppleShare, or Artisoft LANtastic.
Most networks—even those with just two computers—also contain a
hub or
switch to act as a connection point between the computers.
