An operating system (OS) is system software that manages computer hardware, software resources, and provides various services for computer programs. It acts as an intermediary between users and the computer hardware. Examples of popular operating systems include Microsoft Windows, Apple's macOS, Linux distributions, and Android for mobile devices. The operating system performs basic tasks, such as controlling and allocating memory, prioritizing system requests, controlling input and output devices, facilitating network communications, and managing files. It also may include a set of applications, such as utility programs, that manage tasks like displaying graphics and text, managing files and directories, securing access, and more. Is there anything specific you would like to know about operating systems? 😊

2. “What is Operating System”?
• Operating System lies in the category of
system software. It basically manages all the
resources of the computer. An operating
system acts as an interface between the
software and different parts of the computer
or the computer hardware. The operating
system is designed in such a way that it can
manage the overall resources and operations
of the computer.

3. • Operating System is a fully integrated set of
specialized programs that handle all the
operations of the computer. It controls and
monitors the execution of all other programs
that reside in the computer, which also
includes application programs and other
system software of the computer.

4. • An Operating System (OS) is a collection of
software that manages computer hardware
resources and provides common services for
computer programs. The operating system is
the most important type of system software in
a computer system.

5. What is an Operating System Used
for?
• The operating system helps in improving the
computer software as well as hardware.
Without OS, it became very difficult for any
application to be user-friendly. The Operating
System provides a user with an interface that
makes any application attractive and user-
friendly.

6. • The operating System comes with a large
number of device drivers that make OS
services reachable to the hardware
environment. Each and every application
present in the system requires the Operating
System. The operating system works as a
communication channel between system
hardware and system software.

7. • The operating system helps an application
with the hardware part without knowing
about the actual hardware configuration. It is
one of the most important parts of the system
and hence it is present in every device,
whether large or small device.

8. “Types of Operating Systems”
• A Batch Operating System is a type of
operating system that does not interact with
the computer directly. There is an operator
who takes similar jobs having the same
requirements and groups them into batches.
 Examples of Batch based Operating System:
Payroll System, Bank Statements etc.

9. Time-sharing Operating System
• Time-sharing Operating System is a type of
operating system that allows many users to
share computer resources (maximum
utilization of the resources).
Examples of Time-Sharing OS
Multics.
UNIX.
Linux.

10. Distributed Operating System
• Distributed Operating System is a type of
operating system that manages a group of
different computers and makes appear to be a
single computer. These operating systems are
designed to operate on a network of computers.
They allow multiple users to access shared
resources and communicate with each other over
the network.
 Examples include Microsoft Windows Server and
various distributions of Linux designed for
servers.

11. Network Operating System
• Network Operating System is a type of operating
system that runs on a server and provides the
capability to manage data, users, groups, security,
applications, and other networking functions.
Examples of Network Operating Systems are
UNIX, Linux, Microsoft Windows Server 2008,
Microsoft Windows Server 2003, Novell NetWare,
Banyan's VINES, Artisoft's LANtastic, Mac OS X,
and BSD

12. Real-time Operating System
• is a type of operating system that serves a real-time
system and the time interval required to process and
respond to inputs is very small. These operating systems
are designed to respond to events in real time. They are
used in applications that require quick and deterministic
responses, such as embedded systems, industrial control
systems, and robotics.
Example of Real Time Operating System
• Deos (DDC-I)
• embOS (SEGGER)
• FreeRTOS (Amazon)
• Integrity (Green Hills Software)

13. Multiprocessing Operating System
• are used in operating systems to boost the
performance of multiple CPUs within a single
computer system. Multiple CPUs are linked
together so that a job can be divided and
executed more quickly.
Examples of Multiprocessor Operating Systems
 Windows NT, 2000, XP, Unix, Intel Nehalem –
Westmere, Beckton, and Sandy Bridge

14. Single-User Operating Systems
• are designed to support a single user at a
time.
 Examples include Microsoft Windows for
personal computers and Apple macOS.

15. Multi-User Operating Systems
• are designed to support multiple users
simultaneously.
 Examples include Linux and Unix.

16. Embedded Operating Systems
• are designed to run on devices with limited
resources, such as smartphones, wearable
devices, and household appliances.
Examples include Google’s Android and
Apple’s iOS.

17. Cluster Operating Systems
• are designed to run on a group of computers,
or a cluster, to work together as a single
system. They are used for high-performance
computing and for applications that require
high availability and reliability.
 Examples include Rocks Cluster Distribution
and OpenMPI.

18. “Examples of Operating Systems”
• Windows (GUI-based, PC)-Windows is a
desktop operating system developed by Microsoft.
For the past three decades, Windows has been the
most popular operating system for personal
computers.

19. • GNU/Linux-It is a combination of operating system
components and services that together create the Linux
operating system. GNU/Linux is considered the first version of
Linux that was built alongside the components and services of
GNU and the Linux kernel. When used to refer to the general
operating system, the terms "GNU/Linux" and "Linux" are
interchangeable. Proponents of the term GNU/Linux argue
that it is more accurate to describe the operating system.

20. • Android-It is used by several smartphones and
tablets, such as the Sony Xperia, the Samsung
Galaxy, and the Google Nexus One. Android is
based on the Linux kernel and is open source,
meaning developers can modify and customize
it. Android is part of the Open Handset Alliance
(OHA), a collaboration of companies that aim to
deliver a complete software set for mobile
devices.

21. • iOS- iOS is the mobile operating system that
Apple uses for its iPhones. Until recently, it was
also used on iPads (and still sort of is).
• iOS runs on all models of iPhones and its primary
rival is Google’s Android. iOS was first released
alongside the iPhone in 2007 and began running
on iPads and models of iPod Touch alike.

22. • macOS -macOS is an operating
system designed by Apple. The operating
system is what allows you to use a computer.
macOS comes preloaded on all new Apple
Macintosh computers (commonly known
as Macs).
