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 terabyte?

The terabyte is the current heavyweight of all data storage. The terabyte represents 1,000^4 bytes. In other words, it is the equivalent of one TRILLION bytes of information. This can also be expressed in more technical terms as 1,024^4 (1,099,511,627,776) bytes. Thanks to advances in storage and processing power, the terabyte is now commonly seen in external hard drives and other systems which provide massive amounts of memory space. As the world of computing continues to advance, it will be interesting to see how far these massive figures will rise!
