Computer Performance

1. Cores

   • How
     • If there are more cores the CPU will be faster
   • What
     • Cores are independent processors in the CPU
     • Cores run the fetch decode execute cycle simultaneously

2. Cache

   • What
     • Cache is a small amount of memory In or close to the CPU
     • Cache is faster AND more expensive than RAM
     • Cache memory stores frequently used instructions
   • How
     • The larger the amount of cache the greater the amount of instructions stored

3. Clock speed

   • What
     • Clock speed is measured in hertz
     • Number of fetch decode execute cycles committed in a single second
   • How
     • The higher the clock speed the more instructions processed and executed in a single SECOND

4. RAM

   • How
   • What
     • Volatile st
