System Resources That Affect System Performance

The performance of a computer system depends on how the system uses and allocates its resources. Monitor the performance of your system regularly so that you know how it behaves under normal conditions.

    The following system resources affect performance:

  • Central processing unit (CPU) – The CPU processes instructions by fetching instructions from memory and executing them

  • Input/output (I/O) devices – The CPU processes instructions by fetching instructions from memory and executing them.

  • Memory – Physical (or main) memory is the amount of random access memory (RAM) on the system.
