We listen to the words megabyte, gigabyte, terabyte, etc., a lot, but do we really intuitively understand how much data it means to say a gigabyte?
When people use terms like these, they often do so in the abstract sense without having much of a realistic handle on what they actually mean in the real world, or what sorts of digital data sizes they actually correspond to.
Computers and storage devices (CD-ROM, hard drive, USB flash drive, DVD-ROM, Blu-ray Disc, etc.) need to hold much larger values than what a byte can hold (0-255). Thus, the terms kilobyte, megabyte, gigabyte, terabyte, petabyte, exabyte, zettabyte, and yottabyte were created to represent such large amounts of information.
The following tips by Focus translate in real-world terms how much data your storage devices can contain, with actual concrete examples.
