There's a practical reason:
octal and hexadecimal numbers are easily translated to binary numbers
and vice versa.
you take your binary number, take four (hexa)/three(octal) digits
and translate them and you get the right hexa/octal number right away.
cuz computers can handle bin-nums for technical reasons only,
it is easyer to take hex or oct nums instead of decimals.
