INFORMATION PROCESSES
Collecting
It is the information process that involves deciding what to collect, locating and collecting it. Collecting involves 4 steps:
Organising
It is the process which arranges, represents and formats the data for use by other information processes. The organisation of data depends on the purpose of the information system. Organisation gives some structure to the data
Analysing
It is the process that interprets data transferring it into information. It involves examining data and giving meaning to it. When data has been ordered and given some meaning by people, it is called information.
Storing and Retrieving
Storing and Retrieving is a 2 step process for retrieving data: Storing saves data for later use; Retrieving data obtains data that had been previously saved. Before, during and after processing, data and programs are temporarily held in the memory
Processing
Processing is the manipulation of data and information. It occurs when data or information is modified and updated. It is carried out by the CPU(Central Processing Unit)
Transmitting and Receiving
Transmitting and Receiving is the transfer of data within and between information systems. Data is transferred between computers and derived in 2 ways:
Displaying
Displaying is the presentation of information for an information system. It must be well organised, attractively presented and easy to read and understand. It can be displayed via screens, printers, speakers and plotters

- defining the required data- deciding what is required
- identifying the source of the data
- determining how the data will be gathered

Transmitting and Receiving is the transfer of data within and between information systems. Data is transferred between computers and derived in 2 ways:
- serial transmission
- parallel transmission
