- How information is represented using electricity.
- How computers use circuits
- The 4 parts of a computer:
- input
- cpu
- memory

The pioneers of Computer science explord how to design a thinking machine thye realized that it had to perfome four tasks , take input store information process it and then output the results.
- first input : You can tell the computer what you want via the keyboard , the mouse , the microphone and the camera .
- storage and processing : All of these inputs and information are stored in the computer's memory ,a computer processor tasks information from memory it's changes is using an algorithm (serise of commands ) thin it sends the processed information again to memory this continues until the information is ready to be output.
