What is the binary number system?
Binary (base-2) uses only two digits: 0 and 1. It is the fundamental number system used by computers and digital electronics.
Why do computers use binary?
Computers use binary because electronic circuits have two stable states (on/off, high/low voltage), making base-2 the natural representation for digital data.
How do you count in binary?
0, 1, 10, 11, 100, 101, 110, 111, 1000... Each position doubles in value from right to left (1, 2, 4, 8, 16, 32, 64, 128, ...).
