1.8 Multiples of Bit

✅ Multiples of Bit

bit, Byte, Kilo, Mega, Giga, Tera, Petta, Exa, Zelta, Yotta

  • 1b = 1bit = 0(0.5v) or 1(5v)
  • 1B = 1byte = 8 bits
  • 1KB(kilo) = 1024 bytes
  • 1MB(Mega) = 1024 bytes * 1024 bytes = 1024KB
  • 1GB(Giga) = 1024 bytes * 1024 bytes * 1024 bytes = 1024MB
  • 1TB(Tera) = 1024GB
  • 1PB(Petta) = 1024TB ➡️ does not exist yet ❌
  • 1EB(Exa) = 1024PB ➡️ does not exist yet ❌
  • 1ZB(Zelta) = 1024EB ➡️ does not exist yet ❌
  • 1YB(Yotta) = 1024ZB ➡️ does not exist yet ❌

📚 Rule of Multiples of bit

  • normally, bit is written on the right, YB on the left
  • If you pass from big ➡️ smaller (from left ➡️ right)
  • each step has a value of multiplying by 1024(2^10)
  • except the last step, which is byte ➡️ bit
  • which is multiplied by 8 = 2^3

  • If you pass from small ➡️ bigger (from right ➡️ left)
  • each step has a value of divide by 1024(2^10)
  • which is the same as multiplying by 2^(-10)
  • except the first step, which is bit ➡️ byte
  • which is divided by 8 = 2^3
  • which is the same as divided by 2^(-3)
