- 1CPUCentral Processing Unit
- 2Fetch Decode Execute cyclesIt fetches the data from the Cpu. Then the data is decoded. Then it is used (executed)
- 3Clock speedThe amount of fetch decode execute cycles are done per second
- 4HzWhat is used to measure Clock Speed
- 5Mother boardWhere all the components are connected
- 6CoresThe amount of fetch decode execute cycles are done at the same time
- 7CacheA bit of memory that is used for instructions. The data stored in it is closer to the CPU
