- Computer data storage can be regarded complex system, immediately a data is saved then;
- The first be converted to simple numbers of 1s and 0s , this number are very easy for a computer to store and these number are regarded as Binary Numbers and all letters as well as photographs are converted to numbers,
- The hardware will record this saved numbers inside the computer.
