Computer Number System

The base-2 number system used by computers.

What is a 'bit'?

Short for "binary digit"; the smallest unit of data in a computer.

Why Binary?

Binary allows for simpler electronic circuits (on/off) and requires less memory.

What are bytes?

A group of bits (usually 8) that represents a character, number, or symbol.

Study Notes

Number Systems in Computers

  • Computers use the binary number system.
  • 'Bit' stands for Binary Digit.

Binary System

  • Computers use binary instead of the decimal system because it can be easily represented using electronic switches that are either on (1) or off (0).
  • Binary has only two possible states: 0 and 1.
  • In the context of a light switch, binary represents the on or off state.

Bits and Combinations

  • Bits are combined to create bytes in computers.
  • When bits are strung together in different combinations, they can represent different types of data, such as letters, numbers, and images.

Binary Code

  • Computers process and execute the binary code.
  • If computers used the decimal system instead of binary, it would be much more complicated and difficult to implement.

Digital World

  • Everything in the digital world is made up of binary code.
