Essay on computer operating system

Many computer users run a modified version of the GNU system every day, without realizing it. There really is a Linux, and these people are using it, but it is just a part of the system they use.

Linux is the kernel: The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Linux is normally used in combination with the GNU operating system: The ambiguous use of the name doesn't help people understand.

These users often think that Linus Torvalds developed the whole operating system inwith a Essay on computer operating system of help. Programmers generally know that Linux is a kernel. For example, many believe that once Linus Torvalds finished writing Linux, the kernel, its users looked around for other free software to go with it, and found that for no particular reason most everything necessary to make a Unix-like system was already available.

What they found was no accident—it was the not-quite-complete GNU system. The available free software added up to a complete system because the GNU Project had been working since to make one. By the time Linux was started, GNU was almost finished. Most free software projects have the goal of developing a particular program for a particular job.

It's natural to measure the contribution of this kind of project by specific programs that came from the project. If we tried to measure the GNU Project's contribution in this way, what would we conclude? The proportions in are similar: But that is not the deepest way to consider the question.

The GNU Project was not, is not, a project to develop specific software packages. It was not a project to develop a C compileralthough we did that. It was not a project to develop a text editor, although we developed one. Many people have made major contributions to the free software in the system, and they all deserve credit for their software.

But the reason it is an integrated system—and not just a collection of useful programs—is because the GNU Project set out to make it one. We made a list of the programs needed to make a complete free system, and we systematically found, wrote, or found people to write everything on the list.

We wrote essential but unexciting 1 components because you can't have a system without them. Some of our system components, the programming tools, became popular on their own among programmers, but we wrote many components that are not tools 2.

We even developed a chess game, GNU Chess, because a complete system needs games too. By the early 90s we had put together the whole system aside from the kernel. Developing this kernel has been a lot harder than we expected; the GNU Hurd started working reliably inbut it is a long way from being ready for people to use in general.

Fortunately, we didn't have to wait for the Hurd, because of Linux. Making them work well together was not a trivial job.

Some GNU components 3 needed substantial change to work with Linux. It required addressing the issue of how to install and boot the system—a problem we had not tackled, because we hadn't yet reached that point.

Thus, the people who developed the various system distributions did a lot of essential work.Operating system, Computer, Windows Vista - Computers Should Be Used For Tablets. My Account.
