Computer performance

1. Clock speed

   • What?
     • Clock speed is how many fetch decode and executes cycles per second
   • Why?
     • More Fetch, decode and execute cycles can be processed per second

2. RAM

   • What?
     • RAM stands for random access memory
     • It stores the programs, part of the operating system and the files currently being used
   • Why?
     • It won't need to rely on virtual memory as much

3. Cores

   • What?
     • The number of independent processors in the CPU which run the fetch decode and execute cycle simultaneously
   • Why?
     • More instructions can be processed at once

4. Cache

   • What?
     • The memory in the CPU needed to store frequently accessed data.
   • Why?
     • You can access frequently used data quicker
