What make a computer, a computer?

• the idea start from building a machine for thinking work rather than any physical work.
• the best four things common in all computers in the world are:
  • Input
  • storage
  • Processing
  • Output

How computer work?

### Data + Binary

• Inside a computer there are electric wires and circuits that carry information in the computer.
• the electricity flowing through the single wires
• the signal have two choices: YES(ON) or NO(OFF)
• This on/off state of a single wire called Bit ### circuits and logic
• To process the input into output we have to modify and combine the input signals.
• this done by circuits which are teeny electronic coponents comes togaher
• small circuits perform simple logical calculation
• complex circuits combined small circuits togather to perform complex calculation.
• the speciality of these calculation are Faster than human.
