Computing uses three number bases:- Binary (base 2), Octal (base 8) and Hexadecimal (base 16). Binary has been described before, although various catchphrases are used to describe their length.
4 bits e.g. 1100 is termed nibble 8 bits e.g. 11001111 us termed Byte 16 bits e.g. 1100111111001111 is termed Word 32 bits e.g. 11001111110011111100111111001111 is termed long word. Hexadecimal (Hex) is a common base; it uses 0 -> 9 and A -> F for 10 -> 15. Conversion to decimal is achieved by using weighted columns of 16n similar to binary.
