computer performance

1. cores

   • what
     • small cpu's
     • they are built into a bigger CPU
     • cores run fetch decode execute
     • dual cores means 2 independant processors
   • how
     • they make the computer able to run more programs
     • more cores make the computer process faster
     • if there is more cores the computer will run faster

2. clock speed

   • what
     • the number of time the CPU take to do the actions fetch decode exacute
     • measured in hertz (Hz)
     • the higher the clock speed the more instructions are processed
   • how
     • it helps to have a higher clock speed so the computer is faster
     • the higher the clock speed the more instructions the computer can do at a time

3. RAM

   • what
     • random access memory
     • volatile storage
   • how
     • data is not saved when turned off
     • it stores data that the computer is using

4. cache

   • what
     • quicker to send data to the CPU than RAM but more expensive
     • cache holds the same data as RAM just faster
   • how
     • it is built closer to the CPU so the data take less time to get there
     • its faster because it doesn't have to be refreshed often
     • you want to have more since it would make it a lot
