computer performance

1. Cache

   • What
     • Cache is a piece of hard ware that can retrieves data from memory more efficiently.
     • Cache is a small amount of memory which is inside of the CPU or closer to CPU than RAM.
   • how
     • it helps it by retrieving the data more quickly instead of taking the long way around to RAM.

2. clock speed

   • What
     • The clock speed is the perforance rate of the speed of your applications .The faster rate of the clock speed the more fetch-decode-execute it will do.
     • It is measured in hertz
   • how
     • It is the speed that is the processor speed that makes all the applications that you have opened run faster and load faster.

3. Cores

   • how
     • it helps by having duel or quad core processors in it because it speeds it up.
   • what
     • cores is the number of independent processors in the CPU the does the fetch-decode-execute process over and over again.
     • They are independent processors in the CPU
     • Cores run the fetch decode execute cycle simultaneously.
     • Duel core is where there are 2 processors and in a quad core there is 4 processors

4. RAM

   • what
     • RAM stores the applications that you are using
     • RAM is volatile storage
   • how
     • it helps it by storing the programs that you using and it doesnt get rid of them
