communications |
| |
| Data
communications equipment enables computers
to connect to each other and exchange information.These
computers may be in the same building, or
campus, or they may be sparated by large
distances. |
|
| |
| When
the computers are in the same building, or
campus, they are connected by a local area
network. This requires networking devices
in each computer, a communications link between
each computer (cable or radio) and a hub,
or switch, to control the transfer of data
between the computers. |
| |
| When
the computers are separated by large distances
they are connected by a wide area network.
This requires modems, ISDN adaptors or similar
devices in each computer, together with a
link to the telephone network or to dedicated
data communication circuits. |
| |
| The
hub or switch of a local area network often
has a device known as a router connected to
it. This gives all the computers on the local
area network access to a wide area network. |
| |
| The
Internet is an example of a wide area network
that enables connections between any computer
in the world that has access to a telephone
line. However, companies such as banks may
prefer to build their own wide area networks
for reasons of security. |
| |
|
We stock modems, ISDN adaptors, hubs and other
data communications equipment in our Edinburgh
shop or if you prefer you can buy from
our on-line shop. |
| |
|
We also stock data communications equipment
that enables laptops and PDAs to be connected
to a wide area network via a mobile phone. |
