What is Linux?

• Linux is the kernel of an operating system.
• Linux was built on the Unix tradition.
• Linux was originally developed by Linus Torwalds
  of Finland, who currenctly owns the Linux
  trademark.
• Linux stands for Linus' Unix.
• Using the open source code of the Linux kernel,
  people have been developing operating systems
  based on the Linux kernel. These are called the
  "Linux distributions".1

History of Linux

• In 1991, Linus Benedict Torvalds was a second
  year student of
• Computer Science at the University of Helsinki
  and a self
• taught hacker. The 21 year old sandy haired
  soft-spoken Finn
• loved to tinker with the power of the computers
  and the limits
• to which the system can be pushed. But all that
  was lacking
• was an operating system that could meet the
  demands of the
• professionals. MINIX was good, but still it was
  simply an
• operating system for the students, designed as a
  teaching tool
• rather than an industry strength one.
• At that time, programmers worldwide were greatly
  inspired by
• the GNU project by Richard Stallman, a software
  movement to
• provide free and quality software. The much
  awaited Gnu C
• compiler was available by then, but there was
  still no operating
• system. Even MINIX had to be licensed. Work was
  going the
• GNU kernel HURD, but that was not supposed to
  come out
• within a few years. Linux version 0.03 came in a
  few weeks. By
• December came version 0.10. Still Linux was
  little more than in
• skeletal form. It had only support for AT hard
  disks, had no
• login ( booted directly to bash). version 0.11
  was much better

The Advantages of Linux
7
Low cost

• You dont need to spend time and money to obtain
  licenses since Linux and much of its software
  come with the GNU General Public License. You can
  start to work immediately without worrying that
  your software may stop working anytime because
  the free trial version expires. 3

8
Stability

• Linux doesnt need to be rebooted periodically to
  maintain performance levels. It doesnt freeze up
  or slow down over time due to memory leaks and
  such. Continuous up-times of hundreds of days (up
  to a year or more) are not uncommon.

9
Performance

• Linux provides persistent high performance on
  workstations and on networks. It can handle
  unusually large numbers of users simultaneously.
  3.http//linux.about.com/cs/linux101/a/linux_2.htm
  

10
Network Friendliness

• Linux was developed by a group of programmers
  over the Internet and has therefore strong
  support for network functionality client and
  server systems can be easily set up on any
  computer running Linux.
• It can perform tasks such as network backups
  faster and more reliably than alternative
  systems. 3.http//linux.about.com/cs/linux101/a/li
  nux_2.htm

11
Flexibility

• Linux can be used for high performance server
  applications, desktop applications, and embedded
  systems. You can save disk space by only
  installing the components needed for a particular
  use. You can restrict the use of specific
  computers by installing for example only selected
  office applications instead of the whole suite.

12
Choice

• The large number of Linux distributions gives you
  a choice. Each distribution is developed and
  supported by a different organization. You can
  pick the one you like best the core
  functionalities are the same most software runs
  on most distributions 3.http//linux.about.com/cs/
  linux101/a/linux_2.htm

13
Compatibility

• It runs all common Unix software packages and can
  process all common file formats.
  3.http//linux.about.com/cs/linux101/a/linux_2.htm
  

14
Fast and easy installation

• Most Linux distributions come with user-friendly
  installation and setup programs.

15
Full use of hard disk

• Linux continues work well even when the hard disk
  is almost full.

16
Multitasking

• Linux is designed to do many things at the
  same time e.g., a large printing job in the
  background wont slow down your other work
  3.http//linux.about.com/cs/linux101/a/linux_2.htm
  

17
Security

• Linux is one of the most secure operating
  systems. Walls and flexible file access
  permission systems prevent access by unwanted
  visitors or viruses.

18
Open source

• If you develop software that requires knowledge
  or modification of the operating system code,
  Linuxs source code is at your fingertips,
• Today, the combination of inexpensive computers
  and free high-quality Linux operating system and
  software provide incredibly low-cost solutions
  for both basic home office use and
  high-performance business and science
  applications. The available choices of Linux
  distributions and Linux software may be
  overwhelming at first, but it if you know where
  to look, it shouldnt take long for you to find
  good online guidance. 3.http//linux.about.com/cs/

Linux Versus Microsoft
20

• Windows is like Linux in a lot of ways and and in
  a lot
• of ways it is not. Let's take a look at a few of
  the
• similarities
• Win and Linux both run on Intel-based PC
  hardware. (Linux also runs on other hardware such
  as the Alpha and Amiga) .
• Win and Linux are both 32-bit operating
  systems.
• Win and Linux both run user applications in
  protected mode. (Except that Win maps memory from
  64KB to 4MB into the address space of all
  applications, with write access to all data areas
  between 64KB and 4MB)
• Win and Linux both include networking. (And,
  of course, Linux includes NFS, NIS, uucp,... in
  other words, a lot more networking with an open
  architecture , which makes it easy to network
  Linux with other operating systems.)

21

• Win and Linux both include a GUI. (Of course,
  the Win95 GUI only runs on whatever runs Win95 .
  The Linux GUI, X-Windows, is available on many
  platforms.)
•   Win and Linux are both written in C. (Well,
  that's what I have heard. While Linux source code
  is freely available, Win95 source is not).
•      Win and Linux are both licensed software
  products. (The licenses do differ the Win95
  license says you can't share the Linux license
  says you must share.)

22
Conclusion

• Most consumers agree that Linux is not as easy
  to use as Microsoft Operating Systems, but in the
  future as linux becomes more user friendly they
  could easy possess a threat to Microsoft, just as
  long as Linux keeps its operating system GNU
  (General Public License).
