This section showed that computers pervade our daily lives, but that many of them are invisible to us.
It investigated the information requirements of certain individuals, such as shoppers and doctors. You learned that their requirements can range from the simple and obvious to the complex and not so obvious.
You also learned that it is not just individuals who require information: it is also essential to the operation of organisations. The example of loyalty cards was used to demonstrate how the data associated with such cards could be used to derive information that could be put to subtle use.
The section also provided simple definitions of data and information, and noted that these will be developed further in this unit.
