What are the advantage of hexadecimal numbering system?
Each hexadecimal digit represents four binary digits (bits) (also called a "nibble"), and the primary use of hexadecimal notation is as a human-friendly representation of values in computing and digital electronics. For example, binary coded byte values can range from 0 to 255 (decimal) but may be more conveniently represented as two hexadecimal digits in the range 00 through FF. Hexadecimal is also commonly used to represent computer memory adresses.
What is a hexdecimal system?
That is "hexadecimal". The decimal system we often used is based on powers of 10 (each place-value is worth 10 times as much as the one to the right); the hexadecimal system is based on powers of 16, and therefore needs 16 different digits. The "digits" commonly used are the digits 0-9, the "A" for 10, "B" for 11, ... "F" for 15.This is commonly used in computers, as a sort of shorthand for writing binary (base-2) numbers.
Who invented hexadecimal and when?
The first use of the term hexadecimal dates to 1954. It is unclear who invented the current hexadecimal notation - most likely IBM. Not all computers used hexadecimal until the end of the 70s or later. Hewlett-Packard continued to use octal instead of hexadecimal until after 1980.
