Document Summary
Represents something complex in an more simpler form (doesn"t have to relate to. E. g to represent fruit on a computer, what could be done is to use letters. One way to convert digital to analogue is through abstrction. Decimal (base 10) 09 (0 counts as a digit) The content of a file is organized in a certain way. Picking a numbering system for a computer (we pick phase 10) Can"t use 10 as a number because you don"t know if its 1 or 0 so you move on to. Some of the numbering systems have interesting feature which makes them useful for other things. Electrical circulates can be either off or on. So using the binary systems we can know for sure if its on or off. Number conversion power of the base and then add up the values. ^2 is the number of zeros after the digit.
