- The Read Only Memory (ROM) chips
- hold information that has been built
- into them. The RAM chips can
- remember what you tell them. But
- the only thing these two kinds of
- chips can remember are "on" and
- "off".
- The memory chips are divided into
- thousands of little compartments
- called bits. Each bit is either
- "on" or "off." The bits are grouped
- together in eights.
- Each group of eight bits is
- called a byte.
- There are 256 possible
- combinations of "on" or "off" in a
- group of eight. You can see how you
- can count with these:
