How Binary Numbers Work
What is Binary?
Binary is a number system that only uses two digits: 0 and 1. Computers use binary because electronic circuits can easily represent two states: OFF (0) and ON (1).
Place Values
In decimal (base 10), we have place values of 1, 10, 100, 1000, etc. In binary (base 2), the place values are 1, 2, 4, 8, 16, 32, 64, 128, etc.
Example: 101 in binary = 4 + 0 + 1 = 5 in decimal
Fun Fact
With 8 bits (called a byte), you can represent any number from 0 to 255. That's 256 different values!
