Question 1 of 10

1. Question
Why do computers use the binary number system?
- Only the digits 1 and 0 will fit into the registers of a CPU
- Computers are made up of switches which only have two states, they therefore cannot represent any more than 2 digits
- The number system enables calculations to be carried out far faster than that of denary
- Binary is a superior number system to all others
