Binary

Basics:

  • It is a series of ONs and OFFs:
    • This is what makes electrical gadgets function.
    • Digital electronics only has these two states.
  • Bases:
    • A thousand is ten to the base 3:
      • 10^3.
    • A hundred is ten to the base 2:
      • 10^2.
    • Ten is ten to the base 1.
    • One is ten to the base 0.

Base 2:

  • Each successive base is equal to 2^(n-1):
    • n being the digit number counted from the right:
      • Say for instance the binary number 10:
        • Since the 1 is the second digit, 0 being the first, from the right.
        • 10 = 21 = 2.

Bits and Bytes:

  • When a flow of electricity is high we call it a 1 and when said flow is low we call it a 0.
    • Each 0 or 1 is a bit.
    • There are 8 bits in a byte.
  • Bits have only 2 possible digits, decimal has 10:
    • This is why it is so much easier to implement base 2.
