depending on whether you are setting up a
network via a hub/switch or as a direct
connection between two computers:
•
Direct connection between two
computers
This type of connection requires a cross-
over cable. These often have a colour
marking. (Sandberg’s crossover cables
are always blue).
•
Connection via a hub/switch
This type of connection requires a stan-
dard UTP network cable (non-
crossover). These are typically white or
grey.
NB: When connecting to the internet via
ADSL/broadband, please refer to the user
guide for your internet connection or con-
tact your internet service provider for infor-
mation about setting up the connection.
TCP/IP protocol
The TCP/IP protocol identifies computers by
numbering them according to a system
similar to an international telephone num-
ber, known as an IP address. The number
consists of four sets of digits separated by a
full stop, similar to the way an international
telephone number consists of country prefix
+ area code + local subscriber
number. (The IP address also comprises a
subnet mask which must be identical for all
computers on the same network. Usually
255.255.255.0 is used.)
In order for computers to be able to com-
municate they must be on the same local
network. In this example the first three sets
of digits must be identical, and the last set
must be unique for each computer.
Example: The computers have the following
IP addresses (numbers):
1) 10.0.0.1
2) 10.0.0.2
3) 10.0.0.3
All the computers have the subnet mask
255.255.255.0 and are members of the
same ”Workgroup”.
These three computers in a network will be
able to communicate as they are all part of
the same local area network and have
unique IP addresses.
