I know i know most of you here, already know this... But I put it together for some, that may not.
What is KB, MB, GB? (Information)
You ever wonder how many bits in a byte, how my KB in an MB, or GB or gig, or do you really have no idea what they're talking about?
Ok, here's a little explanation to help make it a little easier
These measurements are based on the numbers 1,024. This was because of the binary system, which we won't get into. But as long as you can remember 1,024, you'll be ok.
The computer measuring, is no different then the weight system we use. (like Ounce, Pound, Ton, Kiloton, etc.) But do you really know how many ounces are in a ton??? No, because you really don't care.
Well these measurements are just like that, except they are used for computers to express the size of something. Weather it be a disk, a hard drive, the amount of ram, etc.
So if you can just remember that the sizes go in this order
b = bit = 0 or 1
B = byte = 8 bits
kb = kilobit = 1024 bits
KB = Kilobyte = 1024 bytes
MB = Megabyte = 1024 Kilobytes
GB = Gigabyte = 1024 Megabytes
TB = Terabyte = 1024 Gigabytes
PB = Petabyte = 1024 Terabytes
EB = Exabyte = 1024 Petabytes
So now when someone says to you, the file is 3,839 KB, they are also saying it's almost 4 MB.
Most everything is measured in bytes, which stands for (BinarY TablE) (clever huh?) So if you have an 60 gigabyte disk, it will hold approximately 60 billion characters. If you have a 256 megabyte disk, it will hold about 256 million characters. Now this only applies to simple text. Any graphics, or word processing document, would of course not be as much due to the formatting and details. But just to give you an example.
So, next time you read something like Yahoo Mail, and it tells you that you can only send up to 10MB attachments, then you look at your computer and the file size says 8,372KB, now you know if you can send it or not. You do, don't you? Ok, well, I'll give you this one. 10 MB = 10,240 KB. (remember we took 10 x 1,024).
So now you understand it all, right??? lol It's ok, just use the chart above as a cheat sheet, and no one will know the difference.
