CPU

1. Clock speed

   • Rate in which instructions are processed
   • Instructions are processed by transistors
   • Pulses are sent out to the other components to coordinate their activities and ensure instructions are carried out and completed
   • One instruction can be carried out with each pulse of the clock and so the higher the clock speed the faster the CPU will be able to carry out the program instructions
   • One clock cycle is one cycle of the fetch-execute cycle. The faster the speed the more instructions can be fetched and executed per second

2. Overclocking

   • The action of increasing a component's clock rate, running it at a higher speed than it was designed to run
   • People overclock there computing to improve performance and make their computer work faster without the extra cost of upgrading their processor

3. Fetch execute and decode cycle
