Is 40 MB as much as 1 GB?

Answer 1

Sadly, no, 40 MB is not the same as 1 GB.

The basic unit of information storage is the byte (pronounced /ˈbaɪt/). Let's have a quick look at how this system works in practice:

The single solitary byte is usually shortened to just the letter "B", note this is a capitalised letter.

Let's imagine you have something 5 bytes long, this would be written like this: 5 B

Once we have a string of information, it starts to get a bit big, so after 1024 bytes we now have 1 kilobyte, or 1 kB. I won't go into the whole explanation of why we don't call 1000 bytes a kilobyte, it's just one of those things that computer geeks fully understand.

Next, at 1,048,576 bytes (1024 multiplied by 1024), we get 1 megabyte, or 1 MB (note the capital M used here).

At 1,073,741,824 bytes (again, 1024 multiplied by 1024 multiplied by 1024) we get 1 gigabyte, or 1 GB.

Next in line would be the terabyte (TB), then the petabyte (PB), and there are more in the list but unless you work with a super computer you're unlikely to encounter them.

Hopefully by now you'll have realised that 40 MB is quite small in comparison to 1 GB. (1 GB = 1024 MB)
