Is there a relationship between the performance measures from the previous two problems and choosing whether to use polling or interrupt driven communication? What about the choice of using memory mapped or command
driven I/O?

Metrics for I/O performance may vary dramatically from application to application. Where the number of transactions processed dominates performance in some situations, data throughput dominates in others. Explore I/O performance evaluation by answering the questions for the following applications.
