WebBits vs. Bytes - A byte is simply 8 bits of memory or storage. This is the smallest amount of memory that standard computer processors can manipulate in a single operation. If you determine the number of bits of memory that are required, and divide by 8, you will get the number of bytes of memory that are required.
