We've all heard about networking but what is it?
Put simply it is the connection or connectivity between different
items of hardware, i.e. a PC, printer, broadband modem and devices used
to allow connection of these items.
The basic elements of this connectivity are the hardware ( PC,
printer etc) and software ( usually part of the operating system in
Microsoft anyway).

So where do we start? first decide on what or where you
want to connect. So if you have 2 PC's and would like to share data,
printers or even a Broadband connection then you have the requirements of
a network. With 2 PC's in the same location you can use a cable to connect
from PC to PC. Both PC's would require a network Ethernet port, either
found on board or by an installed PCI card. With these installed a
'Cross-over' cable can be used. This is a simple cable that is plugged in
to each machine, and with a bit of configuration of the operating system
will allow each machine to share data and printers. So sharing Broadband
is just allowing the second PC to connect through the first, again a bit
of software configuration. |

That all sounds pretty simple but what about more than
2 PC's? This is a little bit more complex, but only a little bit. We
again start with the PC's again all requiring Ethernet ports, this time
instead of a crossover cable, we use standard straight through cables.
The cable from each PC needs to plug in to box know as a
switch, this switches data between each PC. These switches can also be
used to plug in a printer or a broadband modem which could then be shared
between all PC's. The printer or modem would need to have an Ethernet
connection. There are also switches that have built in
broadband modems these are called routers). There are print servers (
which allow a usb or parallel printer to connect to the network).
Routers are generally much cheaper than an individual modem and switch. Again a
bit of configuration of the software is required and hey presto you have
multiple PC's sharing data, printers, CD Writers, ability to play games
and use the internet.

What's next?
Well I mention that you required cables to connect your PC's well that is not
strictly true, you can buy network equipment that is connected wirelessly, which
within a house or office allows the same connectivity without the cables. A
wireless card can be installed in to a PC or laptop, and allow a wireless
connection. You can have a mixture of cable and wireless.
Lastly we have networks that work over a main ring.
This equipment is a main 13A style plug that has an Ethernet connector.
One would be placed by each PC requiring connection and again with a bit
of configuration a network without wires.

Well that is pretty much it, if you require more
information or advise on how to set up your own network or would like to
have a network without being hands on call PC Southwest on 01392
