Components of information systems

This section of the course is allocated 25 hours

Note: Use of practical tasks whenever and wherever appropriate (e.g. setting up a network, building a computer) is encouraged.
The major emphasis is to be how items of hardware and software are suitable in solving particular information problems, and comparing the suitability of alternatives.  It is not intended that a detailed mechanical/electronic knowledge of the operation of specific devices will be examined.
