GIGABYTES, MEGABYTES, BYTES AND BITS

Bits = the zeroes and ones that make up data and commands in the computer world. The millions of transistors in computer chips can only be in two states: on or off (one or zero). So every number has to be translated into the binary numbering system.

Byte = a group of 8 bits, which is like a "word" in the computer world

Megabyte = 1 million bytes

Gigabyte = 1 billion bytes
