The document discusses the components of a computer system including hardware, operating systems, application software, and users. It defines hardware as the physical elements like monitors, keyboards, and drives. An operating system manages hardware resources and allows other software to run. Popular operating systems mentioned are Windows, MacOS, Linux, and Ubuntu. Application software performs tasks for users like word processing, spreadsheets, presentations. The Microsoft Office suite is a collection of applications including Word, Excel, PowerPoint, and Outlook. Users are individuals who interact with the computer system through user accounts.

2. WHY DO YOU THINK IT IS IMPORTANT TO
STUDY THE OPERATING SYSTEM SUBJECT?

5. FOUR COMPONENTS OF COMPUTER SYSTEM

6. 1. Hardware
2. Operating System
3. Application Programs
4. Users

7. HARDWARE (H/W)

8. • The context of technology, refers to the physical elements that make up a
computer or electronic system and everything else involved that is physically
tangible.
This includes the following:
• Monitor, Mouse, Speakers, Headsets, Printer, Scanner, Hard Drive, Memory,
CPU, Keyboard, etc.
Hardware works hand-in-hand with firmware and software to make a computer
function.

9. FIRMWARE

10. • A software program permanently etched into a hardware device such as
a keyboards, hard drive, BIOS, or video cards.
• It is programmed to give permanent instructions to communicate with
other devices and perform functions like basic input/output tasks.

12. OPERATING SYSTEM

13. OPERATING SYSTEM (OS)

14. • An operating system (OS), in its most general sense, is software that
allows a user to run other applications on a computing device. While it
is possible for a software application to interface directly with
hardware, the vast majority of applications are written for an OS, which
allows them to take advantage of common libraries and not worry
about specific hardware details.

15. OPERATING SYSTEM (OS)

16. The operating system manages a computer's hardware resources,
including: • Input devices such as a keyboard and mouse
• Output devices such as display monitors, printers and scanners •
Network devices such as modems, routers and network connections •
Storage devices such as internal and external drives
The OS also provides services to facilitate the efficient execution and management
of, and memory allocations for, any additional installed software application
programs.

18. OPERATING SYSTEM EXAMPLES

21. WINDOWS OS

22. • Microsoft Windows is a group of OSs manufactured by Microsoft. Windows is
available in 32 and 64-bit versions and offers a graphical user interface (GUI),
multitasking functionalities, virtual memory management capabilities, and
support for several peripheral devices. Windows OSs constitute client as well
as server versions.

23. MACINTOSH OPERATING SYSTEM (MAC OS)

24. • An operating system (OS) designed by Apple Inc. to be installed and operated
on the Apple Macintosh series of computers. Introduced in 1984, it is a
graphical user interface (GUI) based OS that has since been released as
multiple different versions

25. LINUX

26. • Linux is a free open source operating system (OS) based on UNIX that was
created in 1991 by Linus Torvalds. Users can modify and create variations of
the source code, known as distributions, for computers and other devices.
The most common use is as a server, but Linux is also used in desktop
computers, smartphones, e-book readers and gaming consoles, etc.

27. UBUNTU

28. • Ubuntu is an open-source operating system (OS) based on the Debian
GNU/Linux distribution.
• Ubuntu incorporates all the features of a Unix OS with an added customizable
GUI, which makes it popular in universities and research organizations.
Ubuntu is primarily designed to be used on personal computers, although a
server editions does also exist.
• Ubuntu is an African word that literally means "humanity to others."

30. APPLICATION SOFTWARE

31. WHAT IS APPLICATION SOFTWARE?

32. • An application software (app or application for short) is a computer
software designed to perform a group of coordinated functions, tasks, or
activities for the benefit of the user. Examples of an application include a
word processor, a spreadsheet, an accounting application, a web browser,
a media player, a console game or a photo editor.
• This contrasts with system software, which is mainly involved with running
the computer.
