Is 6.5 GB a lot

To answer this question we must start smaller. A basic unit is the byte (B), or character, of data. That is one unit of storage in a computer. It is followed by a kilobyte (KB), or 1,024 bytes of data. (The reason that is NOT 1,000 bytes should be explained another time.)

After this we may see the megabyte (MB), or 1024 X 1024 = 1,048,576 bytes of data.

Next, the gigabyte (GB), 1 MB X 1024 = 1,073,741,824 bytes of data! 6.5 GB = 6,979,321,856 bytes of data! That may be 'a lot' to many people. That may or may not be the population of our planet -- 6.5 billion people!
