Mega Byte This 

When you work with computers you see KB (or KiloBytes) and MB (or MegaBytes) 
all the time but what does it stand for? Basically it's a measurement of memory 
on a computer. To help you understand exactly what in means there is an example 

So What's a Byte anyway?

When you get right down to it computers only know two things off and on.  
That's it just OFF and ON. And a computer expresses OFF as a "0" and ON as a 
"1". Everything you see on the screen right now is just a specifically ordered 
combination of 1's and 0's to the computer that tell it exactly how to display 
this webpage. Now here's the confusing part. Each individual 1 or 0 is called a 
BIT and 8 BITS together is called a BYTE. When you type a 0 the computer 
actually recognizes that zero as the series of 8 BITS or "00000000" 

Here are some examples of what some other numbers and letters look like to the 

      0 = 00000000
     a = 01100001
     L = 01001100
      1 = 00000001
     v = 01110110
     p = 01110000
      2 = 00000010
     $ = 00100100
     z = 01111010

Here's a link to even more if you're curious: 

So, in really super simplified terms, when I type the letter "L" the computer 
translates that to be the BYTE "01001100."  If I typed the letter "L" 50 times 
that would be 50 BYTES of information. If I typed the letter "L" 1000 times 
that would be 1000 BYTES or 1 KiloByte or 1KB.  Actually Bytes are measured in 
powers of 2 so 1KB isn't exactly 1000 bytes, but it is close enough.  Below is 
a chart of common abbreviations and their actual values in bytes:

And here's some even more specific information about how bytes and mega bytes 
are measured:  http://www.t1shopper.com/tools/calculate/
