Q. What are the major differences between operating systems for mainframe computers and personal computers?
Answer: In general operating systems for batch systems have simpler requirements than for personal computers. Batch systems don't have to be concerned with interacting with a user as much as a personal computer.

A pure batch system as well may have not to handle time sharing whereas an operating system must switch rapidly between different jobs.
