Decimal is base 10 — the everyday notation, and the one every other base is usually being translated back into. Octal is base 8 and groups bits in threes. It survives mainly in Unix file permissions, where 755 means three sets of read/write/execute bits. As a worked example, 255 equals 255 in decimal and therefore 377 in octal.
