    1. Information Systems What is an Information System? Data: raw facts and figures. DATA Data is PROCESSED INFORMATION Information: is the meaning we attach to the data when the data has been processed.

    2. Two Types of Information Systems Manual Information System: What are the problems with manual information systems? Example: a telephone directory. Computerised Information System: What are the advantages with computerised information systems? Example: the driver vehicle licensing authority.

    3. The Social Effects of Information Systems History: Before the industrial revolution nearly everyone worked in agriculture. People then started to work in factories, which needed administration and offices. More and more paper was needed to write orders, bills, legal documents. Typewriters were invented to save time writing, then telephones, faxes, and the computer.

    4. The Social Effects of Information Systems Now: This is the information age. Our society is very dependant on information storage and communication. Many people are employed in using some form of information technology.

    5. The Social Effects of Information Systems Is Information Technology a good thing?

    6. The Social Effects of Information Systems Arguments in favour: Repetitive jobs are now done by computers. Higher productivity, less work more leisure. Other countries use IT, need to be competitive in the world. Need technology for: Air traffic control, credit cards, space travel. New jobs created: programming, network management, IT teachers.

    7. The Social Effects of Information Systems Arguments against: Life without IT is slower and less stressful. Computers are cheaper than employing people, they are losing their jobs-higher unemployment. New jobs created are only for the higher skilled. The people who did the repetitive jobs don’t work anymore. Personal information is held on computers. There is a wider gap between some countries now.

    9. The Social Effects of Information Systems Changing Employment Patterns.

    10. The Social Effects of Information Systems Manual tasks in factories e.g. assembly work, and paint spraying are done by robots.

    11. The Social Effects of Information Systems Many industrial processes operate 24 hours a day, and are continually being monitored and controlled by computers. Computers are sometimes used to monitor the performance of the people using them, e.g. the supermarket till stores information of how many customers, how many items, what the items were, etc.

    12. The Social Effects of Information Systems More and more people work from home, decreasing travel to and from work, and ability to live anywhere in the world.

    13. The Social Effects of Information Systems There are fewer paper based systems in offices. Filing clerk jobs are decreasing, computer database operatives are increasing.

    14. The Social Effects of Information Systems There is a continual need to retrain people who can no longer spend a lifetime, or many years in the same job.
