But... I don't think that's what that number means... let me look this up.
Ok here we go.
That number is the number of megabits, (not megabytes) of the capacity of the module.
So, it's 2048 megabits.
Well, how many bits are in a byte? You should know this. It's 8.
Side not for future knowledge:
2048Mb/8Mb = 256MB
The Module is 256MB.
You're the guy from that hamburger train, right?
