  1. GCSE ICT Information and Data: By the end of this, you should be able to state the difference between DATAand INFORMATION. Information

  2. GCSE ICT Information and Data – what’s the difference? • Information systems = hardware and software working together… • It will take DATA that has been INPUT and convert it into INFORMATION. • In other words, an information system processes the DATA to produce INFORMATION. In a diagram…

  3. GCSE ICT Information and Data – what’s the difference? DATA(Input) So, Data is taken from an input device and INPUT into the information system, it PROCESSES it and converts it to information so it can be OUPUT. Information System (Processing) INFORMATION (Output)

  4. GCSE ICT Information and Data – Define the difference? Example: This is a set of data: 85, 60, 65, 90, 70, 50, 40. As it is, it has no meaning, the numbers could mean anything (within reason). Data is raw facts and figures which have no meaning and have not been put into a context (given a purpose)

  5. GCSE ICT Information and Data – Define the difference? However, this DATA can be given a purpose or a context… 85, 60, 65, 90, 70, 50, 40 It will become INFORMATION when I tell you that they are percentages for this years ICT examination… 85%, 60%, 65%, 90%, 70%, 50%, 40%

  6. GCSE ICT Information and Data – Define the difference? The DATA has now become INFORMATION since it has been given a meaning… …INFORMATION occurs when DATA has been PROCESSED… *Processed means taking the values and manipulating them (doing something with them)…

  7. GCSE ICT Information and Data – Define the difference? When we have information we can come up with conclusions and answer questions about the data. Information is data which has been processed to give it meaning. From our data, we can now find out more!! Now that we know what it means…

  8. GCSE ICT Information and Data – Define the difference? • So, we now have percentages of the ICT exam… • 85%, 60%, 65%, 90%, 70%, 50%, 40% • …as it is now information, we can find out more! • What is the average class mark? • What do these marks tell the teacher?

  9. GCSE ICT Information and Data – Define the difference? If the average mark of the class is calculated, the data will give the teacher some useful information… … ICT systems produce information which has been formatted so that a user can make use of it (understand it)… …Information can be paper-based e.g. a report or electronic e.g. a chart shown on a screen.
