User Interface (UI) Design focuses on anticipating what users might need to do and ensuring that the interface has elements that are easy to access, understand, and use to facilitate those actions.
Base on the scenario been described in the question, We are 95% confident that the price of a single hard drive with 33 megahertz speed and 386 CPU falls between $3,943 and $4,987
CPU utilization and response time: CPU utilization is amplified if the overheads that are connected with context switching or alternating are minimized. The context switching outlay can be reduced by performing context switches occasionally. This could on the other hand lead to increasing the response time for processes.
The Average turnaround time and maximum waiting time: Average turnaround time is reduced by implementing the shortest or simple tasks first. Such a scheduling and arrangement strategy could nevertheless starve long-running tasks and in so doing boost their overall waiting time.
I/O device utilization and CPU utilization: CPU utilization is maximized by executing a list of long-running CPU-bound tasks not including the performing context switches. This is maximized by setting up I/O-bound tasks as early as they become ready to run, thus sustaining the overheads of context switches.
