This unit deals with the application of networks in organisations. Learners will be introduced to
the subject through an understanding of the way in which networks enhance the activities
carried out in organisations.
Two main types of benefits to organisations are considered: the improvements in
communications that they can bring and the increased efficiency in the use of resources. The
significant benefits are reflected in the widespread use of network technologies however a
consideration is also given to disadvantages such as increasing complexity and the increased
potential for unauthorised access to information.
Key types of networks are considered from a number of perspectives. Networks that run locally
(local area networks) or over a wider physical area (wide area networks) are covered along with
other characteristics, such as whether the computers are of equal status or whether network
servers are used. Particular examples will be discussed — for example the use of peer-to-peer
technology in internet music file sharing. The internet can be considered as an example of a
wide area network. The differences and similarities are explored with reference to the needs, the
technologies and the services available.
The unit does contain practical activity; this provides opportunities for the application and
confirmation of theoretical understanding as well as providing the basis for learners to
appreciate the work of technical support. Learners will gain an understanding of the function of
individual hardware and software components and how they interconnect within a whole
system.
