We use a number system called Decimal (or Denary). This number system uses ten digits: 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. All numbers in Decimal are made up of these ten digits.
Computers, due to the type of electronics they use (digital), store numbers in a system called Binary. This number system only has just two digits: 0 and 1. All Binary numbers are made up of just 0s and 1s.
