What are the main differences between operating systems for mainframe
computers and personal computers?
Answer: Generally, operating systems for batch systems have simpler
requirements than for personal computers. Batch systems do not have
to be concerned with interacting with a user as much as a personal
computer. As a result, an operating system for a PC must be concerned
with response time for an interactive user. Batch systems do not have
such requirements. A pure batch system also may have not to handle
time sharing, whereas an operating system must switch rapidly between
different jobs.
