minicomputer for commercial applications
▸People was looking for a UNIX based system, which is cheaper
and can run on PC
▸Both DOS, MAC and UNIX were proprietary, i.e., the source code
of their kernel is protected
▸No modification is possible without paying high license fees

▸ GNU STANDS FOR(GNU’s NOT
UNIX)

FOUNDER OF LINUX
▸ In sept 1991, while attending
the University of Helsinki , Torvalds
▸ became curious about operating
systems
▸ frustrated by the licensing of
MINIX, which limited it to
educational use only.
▸ He began to work on his own
operating system which eventually
became the Linux kernel.

9. TEXT
GROWING AND GROWING…
▸In order to encourage wide dissemination of his OS, Linus made
the source code open to public.
▸At the end of 1992 there were about a hundred Linux developers.
▸Next year there were over 1,400 developers representing over 200
corporations.. And the numbers multiplied every year.
▸The kernel which forms the core of the Linux system is the result
of one of the largest cooperative software projects ever attempted.

LINUX TODAY
▸Linux has been used for many computing platforms
▸PC, Mobile, PDA, Supercomputer,…
▸Not only character user interface but graphical user interface
is available
▸Commercial vendors moved in Linux itself to provide freely
distributed code. They make their money by compiling up
various software and gathering them in a distributable format
▸Red Hat, Ubuntu, Suse, Slackware, etc

LINUX – A FREE SOFTWARE
▸ The Free Software Foundation (FSF)
is a nonprofit with a worldwide
mission to promote computer user
freedom and to defend the rights of
all free software users.
▸ Free software is a matter of liberty,
not price. Think of “free” as in “free
speech”, not as in “free beer”.
▸ Means users of a program have the
4 essential freedoms:

13. TEXT
FREE SOFTWARE FOUNDATION
▸ The freedom to run the program as you wish, for any purpose
(freedom 0).
▸ The freedom to study how the program works, and adapt it to your
needs (freedom 1). Access to the source code is a precondition for
this.
▸ The freedom to redistribute copies so you can help your neighbor
(freedom 2).
▸ The freedom to improve the program, and release your improvements
to the public, so that the whole community benefits (freedom 3).
Access to the source code is a precondition for this.
