- cache
- small amount of memory which is a part of the cpu
- more cache = more data
- Level 1 cache is usually part of the cpu chip itself and is the fastest to access
- L2 and L3 are bigger than L1 they are extra caches built between the cpu and the RAM
- small amount of memory which is a part of the cpu
- cores
- A cpu can contain one or more processing units.
- Each core contains an ALU, control unit and registers
- it is common for computers to have two cores (dual
- it is also possible that they can have four (quad) or even more
- the purpose of these cores are that they improve the power to run multiple programs

- clock speed
- indicates the speed at the Cpu can run at
- is possible to overclock which increases the overall speed of the cpu
- is possible to overclock which increases the overall speed of the cpu
- corresponds with how many instructions cycles the cpu can do within a second
- indicates the speed at the Cpu can run at
- I/o controllers
- allows an interface between a hardware device external to the motherboard
- examples are : mouse, keyboard, disk drive and vpu
