Can Linux Replace Windows?
Don't make the mistake of assuming that Linux is some kind of watered-down or underpowered Unix for the masses. Linux is Unix. POSIX certification (compliance with the industry standards for Unix) makes it official that Linux can do everything that a Unix system is supposed to do. The only difference is that Linux works on a personal computer, whereas other versions of Unix run on larger workstations or mainframes.
Linux is also being taken very seriously by the computer industry, with new Linux-compatible versions of popular software packages being announced every month. The Apache Web server software running on Linux platforms powers about half of all Web sites today. Even more telling, Microsoft considers Linux a major threat to its Windows empire.
What Is Linux?
In the early 90s, a geek named Linus Torvalds at the University of Helsinki in Finland thought it would be fun to write a Unix kernel from scratch. He called it Linux, and it was cool but pretty much useless without all the utility programs needed to make it a complete operating system. At the same time, Richard Stallman and his pals at the Free Software Foundation were writing a bunch of freeware Unix utilities collectively known as the GNU Project. It was cool but pretty much useless without a kernel to make it a complete operating system.News of Linux spread quickly over the Internet, and many other Unix programmers joined the effort to enhance it. What we now know as Linux is a combination of Torvald's Linux kernel, the GNU Project software, and some other nifty software bit and pieces developed by programmers from all around the world.
Today Linux is a complete and reliable implementation of the Unix operating system, with the following notable features:
- 32-bit or 64-bit operation (it uses all the speed and power of your CPU)
- Virtual memory (it can use all of your system's RAM)
- Full support for X Windows (Unix's standard graphical user interface)
- TCP/IP networking support (allowing connection to the Internet)
- GNU software support (including a huge amount of free Unix software from the GNU Project)
Note: GNU is one of those recursive acronyms that computer scientists love; it stands for GNU's Not Unix. The GNU Project is an effort sponsored by the Free Software Foundation to provide freely available Unix software. See http://www.gnu.org for related information.
Linux was written totally from scratch without using any of the original AT&T UNIX code. (Throughout this site, UNIX refers to the original trademarked UNIX project invented by AT&T. The term Unix is used here as a generic term for other variants of the operating system.)
Because of that (and because the author is a nice guy), Linux is free. You can obtain the source code, modify, sell or give away the software so long as you provide full source code and don't impose any restrictions on what others do with it.

I've been a Linux user ever since trying out Ubuntu through Windows XP via Wubi. Torched my XP install, that showed me the power of the OS. Initially was pissed, but got to trying different Linux OS's & have settled on Mint (now using 13 LTS).
While I do use Windows 8 for some things, when I want control & security, Mint 13 is my "go to" OS. I also have Mint on computers that cannot run a modern Windows OS.
Who says the best things in life aren't free? Many Thanks to Dr Bob for providing this wonderful site.

But, as Dr. Bob has already pointed out, this site is already a great tutorial on Linux. Download the book in case you want it in one file and need to access offline.
"Unix utilities" means that the folks at the GNU Project were developing applications that were Unix-compatible, or better said, based on Unix's native tools.
could you please differentiate Unix,Linux and Windows interms of users. Before I know that open source is the major difference, other than those things is there any thing?
Waiting for your reply?
Ps.Would not it be good to upgrade to a new CMS? so you can update content more conveniently, is only a suggestion xD, I can help if you want, because I love Linux and the pages that talk about Linux
PWB was a rework of the Bell Labs research group's Unix to make a production quality system that could be used as a work environment for the staff at Bell Labs.
This system was reliable enough that it would typically run without being rebooted from one scheduled hardware maintenance session to the next (about six weeks as I recall) as long as we had no power failures. Actually I did have to reboot it after the Loma Prieta earthquake.
This was at a time when the BSD systems at Berkeley were reportedly averaging around one recovery reboot per day.
U R Hilarious!
i need it, because im a newbie for learn UNIX :]
I was able to obtain a selenium-stabilised styrene acrylate copolymer version encoded onto a multi-threaded cellulose matrix.
I did this by hitting the "print" button.
I welcome your comments. However... I am puzzled by many people who say "Please send me the Linux tutorial." This website *is* your Linux Tutorial! Read everything here, learn all you can, ask questions if you like. But
don't ask me to send what you already have. :-) NO SPAM! If you post garbage, it will be deleted, and you will be banned.
