Basically, hexadecimal number system represents a binary data by dividing each byte in half and expressing the value of each half-byte. Hexadecimal numbers in computing is used for abbreviating lengthy binary representations. By convention, the letters A through F is used to represent the hexadecimal digits corresponding to decimal values 10 through 15. The digits in this system range from 0 to 15. So, the value of a given binary number is − The value of a binary number is based on the presence of 1 bits and their positional value. The following table shows the positional values for an 8-bit binary number, where all bits are set ON. Each position is power of the base, which is 2 for binary number system, and these powers begin at 0 and increase by 1.
