THE MORE RECENT AND FAST GROWING RANGE OF DIGITAL COMMUNICATION.

ICT refers to the communication of data by electronic means, usually over some distance. This is often achieved via networks of sending and receiving equipment, wires and satellite links. The technologies involved in communication tend to be complex. The aspects of digital communication relate primarily to the types of network and the ways of connecting to the internet.
Internal networks usually referred to as a Local Area Network (LAN), this involves linking a number of hardware items (input and output devices plus computer processing). The aim of LAN is to be able to share hardware facilities such as printers or scanners, software applications and data. This type of network is invaluable in the office environment where colleagues need to have access to common data or programmes. External networks often need to communicate with someone outside the internal network in this case, one will need to be part of ‘Wide Area Network’. The internet is the ultimate Wide Area Network (WAN). It is a vast network of networks.  
The nature of information covers topics such as the meaning and value of information; how information is controlled; the limitations of ICT.
Management of Information covers how data is captured, verified and stored for effective use; the manipulation, processing and distribution of information; keeping information secured; designing networks to share in formation.
Information system strategy considers how ICT can be used within a business or organisation as part of achieving goals and objectives.
