computer performance

1. clock speed

   • How ?
     • software/games would run smoothly
     • can prosess more instructions per second ,therefore programs will load/run faster
   • Why?
     • does not meet minimum or recommended spec for software required
     • current processor is too slow
       • device is running slowly
   • what?
     • how fast the device processes instructions
     • GHz -1,00,000,000 instructions per second
     • measured in hertz (Hz)-one instruction per second
     • Fetch -decode -Execute cycle

2. cache

   • HOW ?
     • Can store more frequently accessed instructions/data
     • programs will load faster
   • WHY?
     • speed...
     • to store more frequently accessed instructions /data
     • does not meet minimum or recommended spec for software required
   • WHAT?
     • can process these instructions faster
     • FAST!
     • Very small -measured in MB
     • stores frequently accessed instructions /data

3. cores

   • HOW?
