ICT APPLICATION: DATA HANDLING APPLICATION

Even if you don’t work for a huge business, It can be useful to use computers to keep track of data.

Data that is stored on a computer (as opposed to data written on paper) can be easily:

  • organised / sorted in different ways
  • displayed / printed in a variety of styles and layouts
  • searched for specific things
  • updated – adding / changing / deleting items
  • backed-up – a copy can be made with just a few clicks
  • stored / moved – a memory stick is much smaller than a cupboard full of paper!

What we can store on the Computer:

  • Your Address Book
  • Club / Society Records
  • Results of Surveys
  • Sales Records
  • School Reports
  • School Library Database
