Bits and Bytes

Bits and Bytes

At the deepest hardware level, computers only understand two states: Electricity ON or Electricity OFF. We represent these states as 1 and 0.

  • Bit: The smallest unit of data in a computer. It is a single 0 or 1 (Binary Digit).
  • Byte: A group of 8 bits. A single byte can represent 256 different values (from 00000000 to 11111111).

Everything on your computer—text, images, videos, games—is eventually broken down into billions of bits!
