1. CLOCKSPEED

   • THE NUMBER OF FETCHDECODE EXECUTE CYCLES A CPU CAN PERFORM PER SECOND. THIS IS MEASURED IN HERTZ
   • 1Hz- 1 CYCLE PER SECOND
   • 1KHz - 1000 CYCLES PER SECOND
   • 1MHz - 1,000,000 CYCLES PER SECOND
   • 1GHz -1,000,000,000 CYCLES PER SECOND

2. CORES

   • NUMBER OF INDEPENDENT PROCESSORS IN THE CPU WHICH RUN THE FETCH DECODE EXECUTE CYCLE SIMULTANEOUSLY
   • DUAL CORE: 2 INDEPENDENT PROCESSORS IN THE CPU WORKING
   • QUAD CORE: 4 INDEPENDENT PROCESSORS IN THE CPU WORKING

3. CACHE

   • A CACHE IS A BLOCK OF MEMORY FOR STORING DATA WHICH IS LIKELY USED AGAIN
   • THERES THREE DIFFERENT TYPES OF CACHE
     • L1
     • L2
     • L3
     • CACHE IS A TEMPORARY STORAGE AREA WHERE WEBSITE DATA IS STORED

4. RAM

   • STORES THE PROCESS PARTS OF THE OPERATING SYSTEMS AND THE FLIES CURRENTLY BEING USED
   • RAM IS A VOLATILE
   • DATA IS NOT STORED WHEN THE COMPUTER SYSTEM IS SWITCHED OFF.
