PC Math Lessons

- Computers count in binary (base 2), and not in base 10. The smallest piece of data in a computer is a BIT, which can either be a 0 (or OFF) or 1(or ON).

- BITS vs. BYTES a byte is made up of 8 bits.

- The metric system in the PC world

o Bytes, Kilobytes(KB)

o Megabaytes (MB)

o Gigabytes (GB)

Because of the Base 2 computer counting system, a kilobyte is 1024 bytes not 1000 (like in a base 10 system)
