Octal became widely used in computing when systems such as the UNIVAC 1050, PDP-8, ICL 1900 and IBM mainframes employed 6-bit, 12-bit, 24-bit or 36-bit words. Octal was an ideal abbreviation of binary for these machines because their word size is divisible by three (each octal digit represents three binary digits).

The octal numeral system is the base-8 number system, and uses the digits 0 to 7. That means there are only 8 symbols or digits (0, 1, 2, 3, 4, 5, 6, 7) used to form other numbers. The main advantage of using the octal number system is that it uses fewer digits than the decimal and hexadecimal number system.
May 26, 2017 · An octal number like 0123 means send 001 to the first controller, 010 to the second controller, and 011 to the third controller. Older computers were not 16-, 32-, or 64-bit but instead were often 9-bit or 36-bit. In that case, octal makes more sense because each group of 3 bits was a digit.
Dec 2, 2023 · ‘OCTAL’ is derived from the Latin word ‘OCT’ which means Eight. The number system with base 8 and symbols ranging between 0-7 is known as the Octal Number System. Each digit of an octal number represents a power of 8. It is widely used in computer programming and digital systems.
