A binary number is a number expressed in the base-2 numeral system. In binary, each digit can be either 0 or 1, unlike our familiar decimal system (base-10), which uses digits from 0 to 9.

In binary, each position in a number represents a power of 2. For example:

  • 1 in binary is 1 in decimal (2^0 = 1)
  • 10 in binary is 2 in decimal (2^1 = 2)
  • 11 in binary is 3 in decimal (2^1 + 2^0 = 3)
  • 100 in binary is 4 in decimal (2^2 = 4)
  • 101 in binary is 5 in decimal (2^2 + 2^0 = 5)

And so on. Binary is fundamental in computing because computers represent data and perform calculations using sequences of 0s and 1s.
