cache
1. small amount of memory which is a part of the cpu
2. more cache = more data
3. Level 1 cache is usually part of the cpu chip itself and is the fastest to access
4. L2 and L3 are bigger than L1 they are extra caches built between the cpu and the RAM

2. Each core contains an ALU, control unit and registers
3. it is common for computers to have two cores (dual
  1. it is also possible that they can have four (quad) or even more
    1. the purpose of these cores are that they improve the power to run multiple programs
clock speed
1. indicates the speed at the Cpu can run at
  1. is possible to overclock which increases the overall speed of the cpu
2. corresponds with how many instructions cycles the cpu can do within a second
I/o controllers
1. allows an interface between a hardware device external to the motherboard
  1. examples are : mouse, keyboard, disk drive and vpu
