The topic of this PowerPoint file was: Linux Operating System I had created it in February 2020, most probably. We had a presentation at our university in the course named Information on Computer Science. However, I had made this extensive presentation, and I understood my fault at last. Whatever, the presentation was something as I was the only one with this longer presentation, and definitely, my slides were different from others, unique.

Introduction of Linux
The basic architecture and a basic idea about distro.
The Architecture and Distro of Linux
The comparison between Linux and Microsoft Windows and
which is better among them, why .

4. Welcome!!
The basic concept of Linux :
Linux is a family of open source Unix-like
operating systems based on Linux Kernel,
an operating system kernel first released
on September 17,1991 , by Linus
Torvalds. Linux is typically packaged in a
Linux distribution.

5. The Foundation of Linux
1. The inception started in 1991.
2. “The Linux Foundation” got founded in 2007.
3. The foundation sponsors the work of Linux creator,
Linus Torvalds and is supported by the leading tech
companies and developers from around the world.

6. The naming of “Linux”
>> Linus Torvalds had wanted to call his invention "Freax" , a portmanteau
of "Free" , "Freak" , and "X" (as an allusion to Unix). During the start of his
work on the system, he stored the files under the name "Freax" for about
half of a year.
>> Ari Lemmke, who was one of the volunteer administrators for the FTP
server at the time, did not think that "Freax" was a good name and so that
he named the project "Linux" on the server without consulting Torvalds.
However, Torvalds consented to "Linux" later.

7. The Renowned Mascot
You call it penguin 

8. A
Brief
History
Behind
Tux
The Linux logo, a plump penguin known as Tux, is an open-source
image.
Tux is not the product of an advertising agency, and no money was invested into his development.
Artist Larry Ewing first drew him in 1996 when developers began to feel that one of the things that
Linux really needed was a logo.
But Linus Torvalds has claimed, in various posts to Linux kernel discussion groups over the years,
to have been attacked by a "ferocious penguin” that bit him and infected him with a little known
disease called penguinitis. By the way, Torvalds later said that while he did indeed have a close and
personal encounter with a penguin, the bird wasn't ferocious, and just timidly nibbled on Torvald's
finger.
"Penguinitis makes you stay
awake at nights just thinking
about penguins and feeling
great love towards them.”However, Linux stopped using this logo a pretty
long time ago.

9. 1. Kernel : Kernel is the core part of Linux. It is responsible for all major activities
of this
operating system.
2. System Library : System libraries are special functions or programs.They decide
decide which
application programs or system utilities have access to
Kernel’s
features.
3. SystemUtility : System utility programs are responsible to do specialized, individ
ual level
tasks.

12. SomeLayersofLinuxArchitecture
• Hardware Layer : Hardware consists of all peripheral devices (RAM/
HDD/CPU etc.)
• Kernal : It is the core components of operating system, interacts
directly with hardware, provides low level services to uppe
r
layer components.
• Shell : It takes commands from the user and executes kernel’s
functions.
• Utilities : Utility programs provide the user most of the
functionalities of an operating systems.

13. What is Kernel ?
Kernel
interacts
with the
actual
hardware in
machine
language
Kernel is
the
monarch
who has
overall
control of
everything
Kernel contains various functions (File management, data
transfer, memory management, interrupting issues etc.)

14. User Interface of Linux
The user interface is either a command line interface (CLI), a
graphical user interface (GUI) , or through controls which are associated
with hardware.
CLI shells are text based user interfaces, which use text for both
input and output.
On desktop systems, the most popular user interfaces are the GUI
shells.
Most popular user interfaces are based on the X Window system,
often simply called "X"

17. Distro is the short form of distribution. Distro is a term used to describe a
specific distribution of Linux that is built from the common Linux operating
system and includes additional applications. Red Hat, Debian and SuSe are
all examples of a distro.
Some more examples of distro :
• RPM Based
• Gentoo Based
• Pacman Based
• Slackware Based
• Source Based
• Independent Distros

18. Difference between Windows and Linux Distro
We may think that Linux distro is almost the same as Microsoft Windows Versio
ns (Windows XP, 7, 8, 8.1, 10 , Server etc.).
But that’s not true at all.
As for windows, they have their versions and they usually stop the update of t
heir old versions after releasing their new versions. Like they have already clo
sed their all security and essential updates for Windows XP, 7,
8, 8.1 and there are a lot of reasons behind it (The first reason is for their busi
ness of course ! )
But as for Linux distro, they all are kind of individual entity. Those who work in their
distro project, they always update their distros and there’s also a huge popular comm
unity for Linux. Even, all distro have special community where the user and the admi
nistrators and the official panel team can continue their conversation with each other
and they also solve the problems the user are facing every time. But they are volunte
er here. Don’t expect to get solve of your
every problem instantly though you’ll get the solution of most of the common proble
ms there easily.

32. Required Hardware for Linux
 CPU
 Main Memory
 Minimum 256 MB of Graphics (Internal) [ External GPU would be bett
er.
 Hard Disk space (15GB is recommended at least)
 Sound Card (Modern all motherboard come with built in Sound Card)
 Internet Connection (Wifi or Ethernet)

33. Windows Vs. Linux
Winner is
Linux !!!

34. Most Important Using Sector of Linux
Game Development
Windows
Development
App Development Hardware Firmware
Linux is being used in
Game development ,
Software
Development and also
in many other sectors
of Gaming.
It is being used largely
in firmware upgrading,
software development.
Android apps
development is a daily
tasks of Linux
now-a-days.
Developers use Linux
to create and develop
the firmware of almost
any kind of hardware.
(Like : Wifi router,
PDA etc.)

36. An Honest
Opinion from
us……
Linux is mainly a programmer-based
Operating System. So beginners may
find it boring or difficult to use it.
But if you like coding and also you’re
hoping for becoming a programmer,
then you'll fall in love with Linux after
using it for some days.
