### Quiz

- 1, ON, LO, TRUE, CLEARED
- 0, OFF, LO, FALSE, CLEARED

What is a byte?

- A generic term for the smallest addressable amount of memory on a processor.
- A collection of exactly eight bits.
- Any collection of two or more bits.
- A digital system.

How can we change individual bits if the smallest addressable amount of memory is greater than one bit?

- We use operations that have the effect of reading and writing individual bits even though they are working with a larger data size.
- Even though we may have to address a memory block larger than one bit, there are always operators that allow us to address individual bits as well.
- By placing the processor in its bit-addressable mode.
- We can't - we have to live with the fundamental limits of the processor we are working with.
