Octal numbers can be represented in groups ofnumbers; typically, we humans do not. For one thing itthree bits and hexadecimal numbers can be representedtakes too many bits to represent a number. Remember,in groups of four bits. These groupings can then be usedin the binary number system, a bit is the smallestfor printouts or displays to represent the computer’s4-3
