The binary system, based on 2, is just another special number system and is used by digital electronic devices because digital circuits work on an electrical ‘on or off’ two-state system, a number system based on 2 is therefore much easier for electronic devices to use. Each position represents a specific power of the base (10). For example, the decimal number 1234 consists of the digit 4 in the units position, 3 in the tens position, 2 in the hundreds position, and 1 in the thousands position, and its value can be written as a computer programmer or an IT professional, you should understand the following number of systems which are frequently used in computers.
