## Octal Number System

In early days octal number system was mostly used in minicomputers. The word “OCT” means eight. The octal number system says that it is a number system of base 8 which means that we require 8 different symbols in order to represent any number in octal system. The symbols are 0, 1, 2, 3, 4, … Read more

## Binary to Octal and Octal Binary Conversion

We know that binary and octal are two different kinds of number systems whose bases are 2 and 8 respectively, i.e. they use 2 and 8 digits respectively to represent their numbers and these numbers are 0, 1 (for binary) and 0, 1, 2, 3, 4, 5, 6, 7 (for octal). Now we can transform … Read more
