Linux is a free and open-source operating system based on Unix. It was first released in 1991 by Linus Torvalds in Finland. Linux distributions contain additional software packages on top of the Linux kernel, such as Red Hat, Ubuntu, Debian, and Slackware. Linux is commonly used for servers, routers, desktop computers, mobile devices, and more. It is stable, secure, free to modify, and resistant to viruses.

8.  Linux Distribution is a member of the family
of Unix-like operating systems built on top of
the Linux kernel. Such distributions (often
called distro for short) are operating
systems including a large collection of software
applications such as word processors,
spreadsheets, media players, and database
applications.

9.  Redhat
The popular distribution, minimum in
Indonesia. Redhat is first constitute
distribution which the installation and
operation is easy.

10.  Ubuntu
This distro is the most popular in the
world.Besides very easy to use and have the
user friendly interfaces, Ubuntu also popular
in circle of Newbie/beginner

11.  Debian
Distribution which prioritize stability and
reliability,though sacrifice simplicity and
recency aspect. Debian using .deb in
packet installation program.

12.  Slackware
This distribution ever be a king in Linux world.Almost all
Linux documentation prepared by Slackware. Two things
most important from Slackware are all of contents (kernel,
library or application) already tested. Maybe the system is
old but surely very stable. Second,because Slackware
recommended us to install from source so that every
program installed can be optimize with our system. This is
the reason it can’t use binary RPM and until Slackware
version 4.0, it still using libc5 not glibc2 like the other.

13.  Server(Web Server,Mail Server,Webmail
Server, etc)

14.  Router
(Management
Bandwidth,Management User,Proxy,etc)

15.  Desktop PC / Laptop
Not just for interest of
commercial/business,Linux is very good for
help us to complete our daily/job activity.

16.  Mobile Device & Tablet PC
Android,kind of smartphone popular today which
built from Linux kernel. Rich of feature,stable
system, and of course easy to use (although
beginner)
So no wonder if now Linux is the most popular
and favored Operating System around the world.

17.  Linux is stable operating system
 Wecan change the source code Linux
without pay any fee
 Linux 99% free from viruses
 Linux system is more secure than Windows
 LINUX IS REALLY FREE!

18. Thanks for your
attention guys!
I Hope you will enjoy
with Linux 
