Consider a computer system running a general-purpose workload. Measured utilizations (in terms of time, not space) are given as follows:
---------------------------------------------------
Processor utilization 20.0%
Disk 99.7%
Network 5.0%
--------------------------------------------------
For each of the following changes, say what its likely impact will be on processor utilization, and explain why. Is it likely to significantly increase, marginally increase, significantly decrease, marginally decrease, or have no effect on the processor utilization?
Get a faster CPU
Get a faster disk
Increase the degree of multiprogramming
Get a faster network
