3. An Operating System(O.S.) is Software that manages
computer hardware and software resources and
provides common services for computer programs.
The Operating System is an essential component of
system software .
Application programs usually require an operating system
to function.
For hardware functions such as input and output and
memory allocation, it act as intermediate between
program and computer hardware.

4. The codes are executed directly by hardware and
will frequently make a SYSTEM CALL to an
operating system to be interrupted by it.
Operating systems can be found in almost every
devices form- Cellular phones to Video games
consoles to super computers and many more.
There’s nothing wrong in saying that no device can
work without an operating system.
Examples :- Microsoft Windows, MacOS , Android,
iOS , Linux , UNIX , etc.

5.  The operating system (OS) is the program which starts
up when you turn on your computer and runs
underneath all other programs - without it nothing would
happen at all.
 In simple terms, an operating system is a manager. It
manages all the available resources on a computer, from
the CPU, to memory, to hard disk accesses.
 Tasks the operating system must perform:
◦ Control Hardware
◦ Run Applications
◦ Manage Data and Files
◦ Security

6. Real Time:- It is a MULTITASKING operating System that
aims execution of real-time applications. They use
scheduling algorithm to achieve deterministic behavior.
They provide quick and predictable response to events.
A event-driven system switches between tasks based on
PRIORITIES.
MULTI-USER:-- A Operating system allow multiple
users to access a computer system at same time.
TIME SHARING system and internet servers can be
classified as Multi-user access to a computer
through the sharing of time.

7. Time Sharing: Time sharing operating system
schedule tasks for efficient use of the system and
may also include accounting software for cost
allocation of processor time, mass storage,
printing, and other resources.
MULTI-Tasking:- A operating system allows more
than one program to run at same time. A single –
tasking system has only one running program
Multi-tasking can be of two types
i) Pre-emptive
ii) Co-operative
