I have been using smokeless tobacco on and off for years. I thought I quit numerous times but I now realize that wasn't really the case. You can say that I merely stopped using for periods of time. The difference now is that I finally quit, meaning that I am done and will not start again. I'm well over the hump.
A megabyte is one thousand times larger than a kilobyte. The prefixes mega- and kilo- are used by a metric system of counting which is based on powers of ten. Mega comes from a Greek word megas, which translates as great. In metric systems, mega- denotes one million.
So one kilobyte is actually 1024 bytes, and 1024 of those is (1024 x 1024) 1048576 bytes. In short, one Megabyte is really 1,048,576 bytes. There is a difference of about 48 KB, which is a decent amount. If you have a calculator, you will notice that there is actually a 47KB difference.
