The regular decimal number system you use is base 10. This is because there are ten different digits that is used to represent numbers 0,1,2,3,4,5,6,7,8,9. If you want to count higher you have to start using two digits, 10,11,12,13, etc. Base 8 only use eight digits instead of ten. So you count 0,1,2,3,4,5,6,7 and then start using two digits 10,11,12, etc. This means that 10 in the decimal system is the same as 12 in base 8 and so on. Base 8 was used in some older computer systems because there is exactly three bits per digit. So it is very easy to convert between base 8 numbers and binary numbers. But base 8 lost out to base 16 which added another six digits by using letters from the alphabet and is exactly four bits per digit.
