fundamentals of a computer system

1. compurter systems

   • computer systems are everywhere because they are
     • cheap
     • versatile
     • small
   • what is a system
     • a collection of parts that work together for a common purpose
       • for a system to be useful, it must produce something (an output)
         • it needs to receive and proccess inputs to produce outputs
           • systems often interact with other systems
             • they can be made from many subsystems
               • interconnections between systems are called interfaces
                 • inputs ->
                   • processes ->
                     • outputs
   • a system boundry sperates what is not
     • this can be difficault to define when systems form part of other systems
   • examples of systems
     • it is easy to think of many examples of systems
       • some natural, some man made
         • natural systems such as the solar syatem may not seem to have a purpose
           • but all systems act together in some way
             • and are more than just the sum of individual parts that form them

2. why are computer systems important

3. Reliability

   • as we become more dependant on computer systems
     • we need to be able to trust their reliability
       • in fact, the computer systems that we interact with most of the time are so relatable that we do not give them much thaught

4. Testing

5. standards

6. ethical consideration

7. environmental considerations

8. legal considerations
