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.
So, we can see how these numbers will exponentially add up. This should come as no surprise, as the typical storage capacity of a smartphone is now generally between 2 and 4 gigabytes. That is a lot of bytes!

What is a kilobyte?

As you might have guessed, a kilobyte is commonly defined as consisting of 1,000 bytes. We should point out that its actual value is 1,024 bytes (or 2^10 bytes). Still, most say that this value is very similar to 10^3. It is for this reason that the International System of Units (SI) generally equates the kilobyte with 1,000 bytes. This also helps to somewhat simplify multiplication factors when dealing with such massive numbers. To put this another way, one kilobyte is 10 x 10 x 10 bytes. Although this might seem like a large figure, let's recall that most operating systems contain gigabytes of data capacity!
