computer performance

1. cache

   • what?
     • FAST!!
     • very small-measured in MB
     • stores frequently accessed data/instructions
     • can process instructions faster
   • why?
     • not meeting minimum spec for required software.
     • SPEED!!
     • to store more freq accessed data
   • how?
     • programs will load faster
     • can store more freq accessed data/instructions

2. clock speed

   • what?
     • measured in Hz per sec
       • GHz- 1000000000 instructions per sec
     • fetch-decode-execute cycle
   • how?
     • software/games will run smoothly
     • can process more instructions per second therefore programs load/run faster
   • why?
     • current processor slow
       • device runs slow
     • not meeting minimum spec for required software.

3. cores

   • what?
     • individual processor
     • dual core
     • quad core
     • hexa core
   • why?
     • good for multitasking
     • unmet minimum spec for software
   • how?
     • improves multitasking ability
     • allows multiple applications to run at the same time.

4. RAM

   • what?
     • volatile/temporary
   • why?
   • how?
