Binary Number System Explained
The binary number system uses only two digits: 0 and 1. Each digit is called a "bit". Groups of 8 bits form a byte, which can represent values from 0 to 255. All digital data — text, images, audio — is ultimately stored as binary.
Binary to Decimal Conversion
Each binary digit represents a power of 2. Binary 1101 = 1×8 + 1×4 + 0×2 + 1×1 = 13 in decimal.
