If two computers are interconnected in such a way that data between both computers can be exchanged, you can already
speak of a computer network. Such a connection can be implemented either wirelessly, via copper cable or fiber optic cable.
These connections all differ in the speed in which data can be exchanged, in the costs arising to setup the connection,
and in the security and reliability of the connection.
Whenever two computers have to share common resources like a printer or an Internet connection, you certainly do not
want to stay off-line with your equipment anymore. May we give you a helping hand?
