Curious why when you buy an iPod, computer hard drive, or memory stick there is less memory actually available then what was advertised? For example, you buy a new laptop, advertised having 100GB of hard drive space, actually only seems to have 93GB available? It almost seems as if there is false advertising involved. I'm sorry to say, this isn't the case, rather just a tricky usage of terminology used by memory manufactures. Let me try to explain... You see, digital data is of binary numbers. 1's and 0's, also called bits. A group of eight (8 bits) 1's or/and 0's describe what is known as a byte. There are hence, 256 different values for a byte. ie: 00000000, 00000001, 00000010, 00000011, ... 11111110, 11111111. Digital memory is measured in the number of bytes, although it can also be described in bits. This is where it gets a bit more confusing.... Just as with our decimal number system, when a very large binary number needs to be described, such as 123,456,7
