Probably another stupid question but GB,MB, KB Would anyone care to explain the difference or know of a web page that has a listing of just how much is what?
example: how many MB's equals a GB

Just think multiples of 1000.

1000KB = 1MB

1000MB = 1GB

1000GB = 1 Terabyte

well technically it is 1000's but if you look at 1 gb it always is more then a simple multiple of 1000.... but yes just think of 1000's and you will be fine

Yep. "Kilo-" means 1000, "Mega-" means million, and "Giga-" means billion, "Tera-" is trillion.

So a Kilobyte (KB) is 1000 Bytes, a Megabyte (MB) is 1,000,000 Bytes = 1000 KB etc.

If you think of it that way you will be fine. Technically its more like 1024MB = 1GB, etc because of the 8 bits per byte thing and binary and 2^10...something along those lines.

I just always think of 1000 though or else I go cross-eyed!

1 bit = smallest unit of information: true/false, on/off, yes/no. Usually represented as 0/1.
1 byte = 8 bits. About enough combinations of bits to represent one letter/digit/punctuation mark

And from then, it goes on up in powers of 1000 as described.

Except, often, when dealing with computers, it's easier to get powers of 1024x than exactly 1000x. So, 1KB is often 1024B; 1MB ends up being 1024K. The math is easier for computers that way.

Maybe this article can be more clear:
