The great story of linux part 1

well
hello all and welcome back to this cool and great blog
this is ved here
as i promise to publish a post about the real history of Linux
so here is the post


Unix, the original ancestor of Linux, is an operating system. Or at least it was an operating system; the
original system known as Unix proper is not the "Unix" we know and use today; there are now many "flavors" of Unix, of which Linux has become the most popular


A product of the 1960s, Unix and its related software was invented by Dennis Ritchie, Ken Thompson, Brian
Kernighan, and other hackers at Bell Labs in 1969; its name was a play on "Multics," another operating
system of the time.

In the early days of Unix, any interested party who had the hardware to run it on could get a tape of the
software from Bell Labs, with printed manuals, for a very nominal charge. (This was before the era of
personal computing, and in practice, mostly only universities and research laboratories did this). Local sites
played with the software's source code, extending and customizing the system to their needs and liking.


Beginning in the late 1970s, computer scientists at the University of California, Berkeley, a licensee of the
Unix source code, had been making their own improvements and enhancements to the Unix source during the
course of their research, which included the development of TCP/IP networking. Their work became known
as the BSD ("Berkeley Systems Distribution") flavor of Unix.



The source code of their work was made publicly available under licensing that permitted redistribution, with
source or without, provided that Berkeley was credited for their portions of the code. There are many modern
variants of the original BSD still actively developed today, and some of them−−such as NetBSD and
OpenBSD−−can run on personal computers.


Lets talk about Linux


In the early 1990s, Finnish computer science student Linus Torvalds began hacking on Minix, a small,
Unix−like operating system for personal computers then used in college operating systems courses. He
decided to improve the main software component underlying Minix, called the kernel, by writing his own.
(The kernel is the central component of any Unix−like operating system.)

well here comes the great great question that what is kernel?
well my friends kernel is a "bridge" which connects hardware to software and software to hardware

In late 1991, Torvalds published the first version of this kernel on the Internet, calling it "Linux" (a play on
both Minix and his own name)

When Torvalds published Linux, he used the copyleft software license published by the GNU Project, the
GNU General Public License. Doing so made his software free to use, copy, and modify by
anyone−−provided any copies or variations were kept equally free. Torvalds also invited contributions by
other programmers, and these contributions came; slowly at first but, as the Internet grew, thousands of
hackers and programmers from around the globe contributed to his free software project. The Linux software
was immensely extended and improved so that the Linux−based system of today is a complete, modern
operating system, which can be used by programmers and non−programmers.

well thats all for today we will talk more about it but later
till then stay tuned with us :)
