- Factors that Affect performance
- Clock speed
- Number of cores
- Each core is like a small CPU
inside the main CPU. The
more cores you have allows
your CPU to do multiple
things at once making it
respond faster and that'll also
make your computer run
faster.
- The more cores you have allows you to do
multiple things at once. For example if you're
playing a game and you have the internet in use
in the background and you have a single core
CPU your CPU will have to split its time between
the two tasks. So if you had a dual core
processor and would allow multiple tasks to all
run at equal speeds.

- Cache speed
- Clock speed
- How it works
- The CPU gets given instructions it then decodes it and
then executes this instruction. This process is refered to
by three key words: fetch decode and execute
