Computer Performance

1. Clock Speed

   • Clock speed is the number of fetch decode execute cycles a CPU can perform happening per second. Measured in Hertz (Hz)
   • To improve the clock speed, you need to increase the amount of Hz.
     • This would double the amount of fetch decode execute cycles performed per second.

2. Cores

   • A dual core or a quad core in the CPU working simultaneously.
     • This would increase the amount of fetch decode and execute files per minute
   • The number of independent processors which are in CPU so they run the fetch decode execute cycle simultaneously.

3. RAM

   • RAM stores parts of the operating system, programs and the files that are currently in use.
   • You could improve RAM by increasing its size.
     • This would improve it as less files would have to go to virtual memory which would slow it down.

4. Cache
