What are the main differences between operating systems for mainframe computers and personal computers?
The design goals of operating systems for those machines are quite different. PCs are inexpensive, so wasted resources like CPU cycles are inconsequential. Resources are wasted to improve usability and enhance software user interface functionality. Mainframes are the opposite, so resource use is maximized, at the expensive of ease of use.
Q. Several CPU-scheduling algorithms are parameterized for instance the RR algorithm requires a parameter to indicate the time slice. Multilevel response queues require parameters
