### What is a gigabyte?

A gigabyte is the equivalent of 1,000,000,000 bytes. Still, many fields of computer science will refer to this number as 1,073,741,824 (1,024^3) bytes. This second figure will often be used when speaking about different sizes of RAM within an operating system. To make sense out of this large figure, let's use it in reference:

- 1 gigabyte is 1,000 megabytes.
- 1 gigabyte is 1,000,000 kilobytes.

### What is a megabyte?

Most computer users are very familiar with the megabyte. As you might have already guessed, a megabyte is the equivalent of 1,000,000 bytes (or 10^6 bytes). We should point out that there is more than meets the eye here. While the SI definition is one million bytes of information, many computing professionals will instead use the more precise number of 1,048,576 bytes (1,024^2). This arises from the binary multiples that occur (each byte contains eight bits of information within its string).
