Computer: What is principle of performance and scalability in Computer Architecture?

Computer Architecture have the good performance of computer system. It is implementing concurrency can enhance the performance. The concept of concurrency can be implemented as parallelism or multiple processors with a computer system. The computer performance is measured by the total time needed to execute application program. Another factor that affects the performance is the speed of memory. That is reason the current technology processor is having their own cache memory. Scalability is required in case of multiprocessor to have good performance.

The scalability means that as the cost of multiprocessor increase, the performance should also increase in proportion. The size access time and speed of memories and buses play a major role in the performance of the system.
