3.5 Data payation 3.5.1 binary program settleation Computers economic consumption binary notation i.e. sottish 2. Numeric 1 and 0 only. Numeric data is mate by converting. Integers on existing number into sequence of 1s and 0s alphabetic data is represented by what is termed ASC11 8 second reckon on 16 sec Unicode. If we have n bits we deal represent 2^n various combinations. N=1 or 1;2^1 = 2 combinations N=2 [][]2^2 = 4 combinations 0 0n= 3; 2^3 = 8 etc 01 10 11 Applications 1.color, pixel density > 4 bits, we tin can represent 16 diametric colors. > [c] [o] [lo] [r] [brightness] [content] 16 colors x 2 levels of content x 2 levels of brightness. N=6; 2^6 = 64 unlike combinations. In general the much than bits the more RAM. Memory addressing N bits 2^n different memory locations. The number of locations you can address is a contain of the size of memory.
