Use of binary to represent and store data
Computers can represent and store data as the following:
- integers and real numbers
- characters
- instructions (machine code)
- graphics (bit-mapped and vector)
- sound
- video
Processors can only understand binary. Ultimately, everything that is processed by a computer is handled in one of two states, 1 or 0.
Many devices such as hair straighteners or games consoles make use of the following symbols:
The number 1 represents on and the number 0 represents off.
