What is Linux?

Linux is an operating system created by Linus Torvalds while he was an undergraduate at the University of Helsinki. Linux was created and meant to be used as an alternative or replacement to the other operating systems being used by computer users, similar to MS-DOS, Windows, Mac OSX, etc. Linux is not a program or a set of programs like a word processor of an office suite.

A Brief History

While undertaking his studies at the University of Helsinki, Linus used a version of the UNIX operating system called ‘Minix’. Quite a few requests for modifications and improvements for the operating system were being sent by Linus and other users to Andrew Tanenbaum, Minix’s creator, but he felt that they weren’t necessary. Therefore, Linus decided to produce his own operating system; one that would take into account the users’ comments and propositions for expansions.

A “kernel” is the focal point of every operating system. Without going into remarkable detail, the kernel tells the CPU to carry out what you want the program or application that you’re using to do. An operating system would not exist if it doesn’t have a kernel. Nonetheless, a kernel is also inadequate devoid of any programs or applications.

In 1991, two significant situations evolved that would serve as the preliminary point for Linux. A kernel was previously created by Linus, but he had no programs to use; some programs were accessible from GNU and Richard Stallman, but they had no operational kernel. So Linux was born by combining the programs from Richard and GNU in Cambridge, Massachusetts, with the kernel provided by Linus in Helsinki, Finland. It was a lot of ground to cover and far to travel, so the world wide web became the most important technique of getting Linus’ kernel together with the GNU programs. It can roughly be said that Linux is an operating system that came to life on the world wide web.

Not For Everybody at First

Other software businesses will advertise you software enclosed in a CD or a set of floppies, together with a concise training booklet, and in half an hour or probably even less, you could set up a completely efficient operating system on your computer. You only needed to recognize how to read and go along with instructions in order to install it. This was what those enterpirses had in mind when they developed their operating systems. However, when Linux was developed by Linus, this factor wasn’t first considered. Later on, Red Hat and other like-minded companies made it their goal to develop Linux to the point where it could be effortlessly installed just like any other operating system in the market, by anyone who can follow straightforward instructions, and today we can absolutely say that they have succeeded in this particular purpose. For instance, lots of small business web hosting services are using this such as Linux dedicated servers, and the like.

Linux in this present day

These days, there is a huge deal of constructive reactions from computer users regarding Linux. The reality that Linux has demonstrated to be extraordinarily unwavering and versatile, especially as a network server, definitely has played a big part in this reputation. Down-time is minor when Linux is installed and used as a net server or in corporate networks. Many cases have been reported wherein Linux-powered servers have been functioning efficiently for even more than a year without needing to re-boot, and when it had to be taken down, it was only for a short phase for maintenance purposes. Its cost effectiveness has become to be one of its strongest promotion points. Linux can be installed and run on both a home PC or a network server, without having to pay out as much as it would be for supplementary software packages. More dependability and less cost - it’s the best.
