Chapter 11, Problem 8E

Explanation of Solution

Performance of the system and disk access speed:

  • System performance is considered as one of main factor of a processor.
  • It is used to determine the speed a problem can be solved.
  • It is also used to determine the factors such as number of problems that can be allocated at particular amount of time and also the number of problems that can be handled by the processor.
  • The speed of the CPU is a key factor that often decides the performance of the system.
  • But this factor speed is applied only to identical architecture and which will be misled at many cases.
  • A detailed analysis is made to arrive at a detailed decision for different architecture.
  • Disk access speed is considered to be another factor that is used to determine the performance.
  • The access time is considered to be significantly higher than that of RAM which is almost in orders of millions.

Performance metrics for the system x and Model Q:

Disk access time of the model Q=12ms

Disk access time of the model S=15ms...
