3. WHAT IS AN OPERATING
SYSTEM?
An operating system is the most important software that runs on a
computer. It manages the computer's memory and processes, as well as
all of its software and hardware. Without an operating system, a
computer would be useless.
Think of an operating system as the conductor of an orchestra. It
coordinates all the different parts of the computer, making sure they
work together efficiently and effectively. It also provides a user interface
that allows you to interact with your computer and run applications.

4. FUNCTIONS OF AN OPERATING
SYSTEM
An operating system is responsible for managing the hardware resources of a computer system,
including the CPU, memory, and storage devices. It ensures that each application running on the
system has access to the resources it needs to function properly. The operating system also
provides a layer of abstraction between the hardware and software, allowing developers to write
programs that can run on different types of hardware without needing to know the specifics of
each device.
In addition to managing hardware resources, the operating system is responsible for running
applications on the system. It provides a set of services that allow applications to interact with
the hardware and other software components. This includes managing input and output
operations, scheduling tasks, and allocating memory for running programs. Finally, the operating
system provides a user interface that allows users to interact with the computer system.

5. TYPES OF OPERATING
SYSTEMS
Operating systems come in different types depending on the device they are designed to run on. The most
common types are desktop, mobile and server operating systems.
Desktop operating systems are designed for personal computers and laptops. They provide a graphical user
interface (GUI) that allows users to interact with their computer through icons, windows, and menus.
Examples of popular desktop operating systems include Microsoft Windows and macOS.
Mobile operating systems are designed for smartphones and tablets. They are optimized for touch-based
input and provide features such as GPS, camera support, and mobile app stores. Examples of popular
mobile operating systems include Android and iOS.
Server operating systems are designed for use in data centers and other large-scale computing
environments. They provide advanced networking and security features and are optimized for running
server applications. Examples of popular server operating systems include Linux.

6. Windows Operating System
The Windows operating system is a widely used operating
system developed by Microsoft. It was first introduced in
1985 and has since gone through several major updates,
with the latest version being Windows 11.
One of the key features of Windows is its user-friendly
interface, which allows users to easily navigate and perform
tasks on their computer. In addition, Windows also offers a
wide range of software applications and tools that are
designed to improve productivity and enhance the user
experience.
Windows has a significant market share in the desktop
operating system market, with over 75% of computers
running some version of Windows as of 2021. However, it
faces competition from other operating systems such as
macOS and Linux, particularly in niche markets such as
creative industries and software development.

7. macOS Operating System
macOS is a proprietary operating system
developed by Apple Inc. for their
Macintosh line of computers. It was first
released in 2001 as Mac OS X and has
since undergone several major revisions,
with the latest version being macOS Big
Sur.
One of the key features of macOS is its
user interface, which is known for its
sleek design and ease of use. It also
includes a number of built-in applications
such as Safari, iTunes, and iMovie, as well
as support for popular third-party
software.

8. Linux Operating System
Linux is a free and open-source operating
system that was first released in 1991 by
Linus Torvalds. It is based on the Unix
operating system and has since become one
of the most popular operating systems in use
today.
One of the key features of Linux is its
flexibility and customizability. Users can
modify the source code to create their own
unique versions of the operating system,
making it a popular choice for developers
and tech enthusiasts. Additionally, Linux is
known for its stability, security, and ability to
handle large workloads.

9. CONCLUSION
In conclusion, we have learned that an operating system is a software program that
manages computer hardware and provides common services for computer
programs. We discussed the different types of operating systems, including desktop,
mobile, server, and embedded systems. We also provided overviews of three popular
operating systems: Windows, macOS, and Linux.
Operating systems are crucial to modern computing because they allow users to
interact with their devices and run applications. Without an operating system,
computers would not be able to function as we know them today.
