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.

What is an information system?

  • People,  Hardware,  Software,  Procedures,  Data resources

What are the types of information systems and for what purposes are they used?
eg. operational information systems (TPS)
      GIS, Navigational System.
