Binary Arithmetic: convert a base 10# (not more than 255) to binary Form - 128 64 32 16 8 4 2 -12864321684213400100010-322-205100110011-3219-163 Bits (1’s & 0’s) combine in groups of eight, known as bytes. Each byte (8 bits) gives 2 (8 th power) = 256 possible combinations. The byte forms a common references for computing capacity: 1 kilobyte (KB) = 2 (10 th power) = 1,024 bytes 1 megabyte (MB) = 2 (20 th power) = about 1 million bytes 1 gigabyte (GB) = 2 (30 th power) = about 1 billion bytes Computing power evolved to process larger groups of bits. Eg. 16-bit, 32-nit, 64-bit processors. Note: 16-bit is not twice of 8-bit and 32-bit is not twice of 16-bit. 8 bit gives 2 (8 th power) = 256 variations 16 bit gives 2 (16 th power) = 65,536 variations 32 bit gives 2 (32 nd power) = 4,294,967,296 variations examples shown w. colors, Britney spears Bits and resolutions Natural light signal is represented by color variations
