i + WHY DO WE NEED AN OPERATING SYSTEM?
Without an operating system, a computer cannot work and a user will not be able to use the
programs because the operating system controls and coordinates the activities of software and
hardware as well. The operating system acts as an interface between the computer and the user.
It also helps a user communicate with the computer and vice-versa. It communicates with the
various parts of the computer so that tasks can be performed effectively and without any delay.
