hardware, including mobile phones,
tablet computers, network routers, televisions
, video game consoles, desktop computers,
mainframes and supercomputers.

15. Linux (cont..)

the 10 fastest supercomputers in the world.
 In addition, more than 90% of today's
supercomputers run some variant of Linux.
 Typically Linux is packaged in a format known as a
Linux distribution for desktop and server use. Some
popular mainstream Linux distributions include
Debian (and its derivatives such as Ubuntu), Fedora
and openSUSE.

 The Unix operating system was conceived and
implemented in 1969 at AT&T's Bell Laboratories
 Unix was re-written in the programming language
C by Dennis Ritchie
 Unix quickly grew and became widely adopted by
academic institutions and businesses.

18.  GNU
 The GNU Project, started in 1983 by
Richard Stallman, had the goal of creating a
"complete Unix-compatible software system"
composed entirely of free software.
 By the early 1990s, many of the programs
required in an operating system (such as libraries,
compilers, text editors, a Unix shell,and a
windowing system) were completed .
Richard Stallman, founder of the GNU project

19.  MINIX
 MINIX is an inexpensive minimal Unix-like
operating system, designed for education in
computer science, written by Andrew S.
Tanenbaum. Starting with version 3, MINIX was
free and redesigned for “serious” use.

20. Commercial and popular uptake
 Today, Linux distributions are used in
every domain, from embedded systems
to supercomputers , and have secured
a place in server installations often
using the popular LAMP application
stack
 Use of Linux distributions in home and
enterprise desktops has been growing.

21. Commercial and popular uptake(cont..)
 They have also gained popularity with various
local and national governments.
 The federal government of Brazil is well known for
its support for Linux.
 News of the Russian military creating its own
Linux distribution has also surfaced, and has come
to fruition as the G.H.ost Project.
 The Indian state of Kerala has gone to the extent
of mandating that all state high schools run Linux
on their computers.

22. Commercial and popular uptake(cont..)
 Linux distributions have also become
popular in the netbook market.
Ubuntu, a popular distribution of Linux

23. Design
 A Linux-based system is a modular Unix-like
operating system. It derives much of its basic design
from principles established in Unix during the 1970s
and 1980s.
 User interface
 command line interface (CLI)
− terminal emulator
 graphical user interface (GUI)

30. Desktop (cont..)
 Installing, updating and removing
software in Linux is typically done
through the use of package managers
such as the Synaptic Package Manager
, PackageKit.

31. Servers, mainframes and supercomputers
 Linux distributions have long been used as
server operating systems, and have risen to
prominence in that area.
 Linux distributions are the cornerstone of the
LAMP server-software combination (Linux,
Apache, MySQL, Perl/PHP/Python) .

and Industrial Light & Magic have migrated to
Linux.[101][102][103] According to the Linux
Movies Group, more than 95% of the servers
and desktops at large animation and visual
effects companies use Linux.

influential Linux distribution.
 Debian can be used on a variety of hardware,
from NAS devices to phones, laptops,
desktops and servers.

50. Features
 Debian is known for an abundance of options.
 The current stable release includes over
twenty nine thousand software packages for
nine computer architectures using the Linux
kernel.

with large numbers of packages, and strict policies
regarding packages, promote high quality releases
 easy upgrades between releases, and automated
installation and removal of packages.
 APT expands the functionality of dpkg by searching,
fetching and installing packages from online
repositories along with their dependencies, either
from binary files or by compiling source code. It can
also upgrade packages and upgrade the whole
distribution to a new release.

APT front-end for non-interactive
package management. It offers a
command line user interface and it is
most suitable for upgrades between
major releases.

54. Debian Live
