A multi-user operating system
allows multiple users
to
access a
computer
system
concurrently.
Time-sharing system
can be
classified
as multi-user
systems
as
they enable
a multiple user access
to
a
computer
through
the
sharing
of
time.
Single-user
operating
systems,
as
opposed
to
a
multi-user
operating system,
are
usable
by a
single
user
at
a
time.

them appear to

a

An operating system is the crucial program that manages a computer's resources and acts as an interface between the user and the machine. Various types of operating systems exist, including real-time, multi-user vs. single-user, multi-tasking vs. single-tasking, distributed, and embedded systems. Real-time OS focuses on executing applications instantly, while multi-user systems enable multiple users to access a computer simultaneously. The distinction between multi-tasking and single-tasking lies in the ability to run multiple programs concurrently. Distributed OS manages a group of independent computers as a single unit, while embedded OS is designed for small devices like PDAs with limited resources.
