1. clock speed

   • what
     • measured in hertz one instruction per second
       • fetch-decode-execute cycle
         • how fast the device precesses instructions
           • ghz-1,000,000,000 instructions per second
   • how
     • software/games would run smoothly
       • can process more instructions per second so programs will run faster
   • why
     • current processor is too slow
       • device is running slowly
         • does not meet minimum or recommended spec for software required

2. cores

   • what
     • allows devices to run applications simultanesaly
       • duel core -2
         • quad core-4
   • why
     • good for multitasking
       • minimum specifications for software not being met
   • how
     • improves multitasking

3. cache

   • why
     • does not meet minimum or recommended spec for software required
       • to store frequent instructions
   • what
     • very small-measured in MB
       • stores frequent instructions
   • how
     • store more frequently accessed instructions
       • programs can load faster

4. RAM

   • why
   • what
   • how
