Linux is an open-source operating system that runs on various hardware platforms. It was created in 1991 by Linus Torvalds and is developed collaboratively by its community of users and developers. Linux exists in many different distributions, or "distros", that package the Linux kernel along with other software. Popular distros include Ubuntu, Fedora, openSUSE, Debian, and Arch Linux. Linux is widely used for servers, mainframes, embedded systems, and as an alternative to Windows on desktop computers and laptops. It offers advantages like open source access, customizability, security, and reliability.

2. WHAT IS LINUX.
open source and community-developed operating
system for computers, servers, mainframes,
mobile devices and embedded devices. It is
supported on almost every major computer
platform including x86( Intel 8086 and 8088
microprocessors), ARM( Advanced RISC Machine)
and SPARC(Scalable Processor Architecture),
making it one of the most widely supported
operating systems.

3. Torvalds released the Linux kernel in September 1991. A
community of developers worked to integrate
GNU("GNU's Not Unix!") components with Torvalds'
kernel to create a complete, free operating system known
collectively as Linux. Torvalds continues to develop the
Linux kernel, currently at version 4.9, and a vast
developer community continues to create and integrate a
wide range of components.
Linux is basically a command-line operating system.
However, many distributions (distros) come with a
desktop environment (DE) that provides a GUI
for Linux users.

6. LINUX VS WINDOWS – THE 9 MOST AWESOME
DIFFERENCES

7. • Linux is open source operating system whereas Windows
OS is commercial.
• Linux has access to source code and alters the code as
per user need whereas Windows does not have access to
source code.
• Linux will run faster than windows latest editions even with
a modern desktop environment and features of the
operating system whereas windows are slow on older
hardware.
• Linux distributions don’t collect user data whereas
Windows collect all the user details which lead to privacy
concern.

8. • Linux is more reliable then windows as in Linux we can
kill application if they hung through x kill command
whereas, in windows, we need to try multiple times to
kill it.
• Linux supports a wide variety of free software’s than
windows but windows have a large collection of video
game software.
• In Linux software cost is almost free as all programs,
utilities, complex applications such as open office are
free but windows also have many free programs and
utilities but most of the programs are commercial.

9. • Linux is highly secure because it’s easy to identify bugs
and fix whereas Windows has a large user base and
becomes a target for developers of viruses and
malware.
• Linux is used by corporate organizations as servers
and operating system for security purpose
at Google, Facebook, twitter etc. whereas windows are
mostly used by gamers and business users.
• Linux and windows have same priority over hardware
and driver support in the present situation.

10. LINUX DISTRIBUTION
OR
DISTROS
There are commercially backed distributions, such
as Fedora (Red Hat), openSUSE (SUSE) and
Ubuntu (Canonical Ltd.), and entirely community-
driven distributions, such as Debian, Slackware,
Gentoo and Arch Linux.

12. Kali Linux
Made to be a completely customizable OS, used for
penetration testing. It is based on Debian GNU/Linux and
is used mostly by security experts.
ROSA Linux
A Russian distribution available in three different editions:
ROSA Desktop Fresh, ROSA Enterprise Desktop and
ROSA Enterprise Linux Server, with the latter two aiming
at commercial users. Its desktop editions come bundled
with proprietary software such as Adobe Flash Player,
multimedia codecs and Steam.

15. Lubuntu
Lubuntu is a project that is an official derivative of
the Ubuntu operating system that is "lighter, less
resource hungry and more energy-efficient“.
Red Hat Linux
It was the first Linux distribution to use the RPM
Package Manager as its packaging format, and
over time has served as the starting point for
several other distributions, such as Mandriva
Linux and Yellow Dog Linux.
