Base Eight, also known as octal, is a numeral system that uses eight distinct digits: 0, 1, 2, 3, 4, 5, 6, and 7. Unlike the more common decimal system, which is base ten and uses ten digits, base eight represents values using only these eight symbols. Each position in an octal number represents a power of eight, making it useful in certain computing applications. In computing, base eight can simplify binary representations, as each octal digit corresponds to three binary digits (bits). This makes it easier for programmers to read and write binary data. Base eight is less commonly used than binary or decimal, but it still has its applications, particularly in older computer systems and programming languages.
