Information Processes and Technology Preliminary Course - Tools for Processing

PROCESSING

A method by which data can be manipulated in different ways to produce a new value or result (eg calculating a total, filtering an email, changing the contrast of an image, changing the volume of a wave file).
Whenever you edit a word document, update data in a spreadsheet cell or alter an image, you are "processing data". Processing is often confused with the organising and analysing processes. Organising and alayising normally don not alter the original datat, while processing does.

TYPES OF PROCESSING
A personal computer is normally used as a single complete informatin processing system, it contains all the information all the information technology it needs to peform its tasks.

HARDWARE IN PROCESSING

  • Hardware with fast processors, a lot of RAM and large storage capacity for image, video and audio processing
  • Increased processing speed, by:
  • Increased clock speeds
  • Increased bus capacity
  • Historical and current trends in CPU development

• Social and ethical issues associated with processing
– Ownership of processed data
– Bias in the way participants in the system process data
