Computer Performance

1. Clock Speed

   • What?
     • The clock speed of a CPU is the number of fetch decode execute cycles than can be run every second The higher the clock speed, the more instructions can be executed per second so the performance of the computer will be improved
   • How?

2. Cache

   • How?
     • If there is a larger amount of cache memory storage, a greater number of frequently-used instructions can be stored. This means that more instructions can be accessed quickly, which will improve the performance of the computer RAM stores instructions and data while a program is running The greater the amount of RAM, the more instructions and data can be stored while a program is running. This means that less instructions will be stored in the much slower virtual memory and will therefore improve the performance of the computer
   • What?
     • Cache memory is a small amount of memory which is either inside the CPU or closer to the CPU than RAM Cores are independent processors in the CPU
