Computer performance

Computer performance

1. Clock speed.

   • What?
     • Clock speed measures the amount of fetch decode execute cycles can be processed per second in a CPU.
     • Its measured in hertz.
   • How?
     • If you update your clock speed to a higher one your CPU will be faster because it will process more instructions per second.

2. Cores.

   • How?
     • The more cores the more instructions that can be processed per second and the better the computers performance.
   • What?
     • Cores are independent processors of the CPU.
     • The average cores per CPU are 2-4.
     • Cores simultaneously.

3. Cache

   • How?
     • If you increase the amount of cache per CPU then it will be able to hold more frequently accessed instructions.
   • What?
     • It collects temporary information to help websites and browsers open faster.
     • Its a reserved storage location.
     • It holds frequently accessed instructions.

4. RAM

   • How?
     • The more RAM there is the more information that can be stored while a program is running.
   • What?
     • It allows applications a place to store and access data on a short term basis.
     • Volatile storage.
