PERFORMANCE

1. CLOCK speed

   • WHAT
     • MEASURED IN HUTTS
     • THE SPEED OF THE FETCH DECODE EXECUte
     • THE FASTER THE CLOCK SPEED THE FASTER THE COMPUTER
   • HOW
     • HOW FAST THE CPU DOES INSTRUCTIONS
     • THE HIGHER THE CLOCK SPEED THE MORE INSTRUCTIONS WILL BE DONE PER SECOND AND THE PERFORMANCE OF the COMPUTER WILL BE BETTER

2. RAM

   • WHAT
     • STORES INSTRUCTUCTION WHILE PROGRAMS/APPS ARE RUNNING
     • WHEN THE COMPUTER IS TURNED OFF ALL INSTRUCTIONS ARE LOST
   • HOW
     • THE BIGGER/LARGER THE RAM IS THE MORE INSTRUCTIONS CAN BE RUNNED AT THE SAME TIME
     • IF THE RAM DOES NOT HAVE ENOUGH SPACE THE INSTRUCTIONS ARE STORED IN THE NON VOLLITILE STORAGE
     • THE GREATER THE RAM THE MORE INSTRUCTIONS CAN BE STORED MEANING THAT YOU CAN OPEN A LOT OF STUFF AND STILL HAVE STORAGE FOR YOUR CPU TO WORK WITH AND THE INSTRUCTIONS DON'T NEED TO GO TO VIRTUAL STORAGE.

3. CORES

   • HOW
     • there is no limit at how many you can have
     • the faster the cores are the more tasks they can fetch and complete
   • WHAT
     • QUAD CORES MEANS 4 CORES THAT ARE INDEPENDENT AND THAT WORK 4X FASTER MEANING THAT YOU CAN DO MORE THING IN THE SAME AMOUT OF TIME
     • DUAL CORES MEANS THAT YOU HAVE 2 CORES THAT ARE INDEPENDENT AND DO WORK AT 2X SPEED MEANING THAT YOU CAN DO MORE THING IN THE SAME AMOUT OF TIME
     • THE more there are the faster the tasks will be done
     • the more there are the more tasks can be done at the same time
     • the faster the cores are the more tasks can be done faster

4. C.A.S.H

   • HOW
     • IT SENDS MORE DATA TO THE CPU MEANING THAT IT CAN DO MORE STUFF AND NOT JUST SIT AROUND CHILLING
   • WHAT
     • VERY VERY FAST BUT NEEDS TO BE Next to THE CPU
     • BETTER THAN RAM BUT MORE EXPENSIVE
