There are many different operating systems that you can run on your personal computer (PC), but some people may not realize that.

Unfortunately, Windows has become so common that people have been blinded to the wide range of choices that they have-and often carrying a far cheaper price tag.

Though Microsoft Windows has the largest market share, there are also Apple computers, and the Linux and Unix operating systems.

Apple operating systems require an entirely different architecture on which to run, and so won’t run on a normal PC, so are not an option for users of normal PCs. A Linux operating system is a good alternative to Windows, and can be tried quickly and easily and with no commitment

The owner of a normal PC has several usable choices when in comes to running their computer. There are Unix based operating systems, Linux systems and there is the Google Chrome system. Unix tends to require a little more technical know-how, and Chrome is very basic, leaving Linux the big competitor. Read the rest of this entry →

The first Linux systems were completed in 1992 by combining system utilities and libraries from the GNU project which is another operating system we’ll address next.

Predominantly known for its use in servers, Linux is used as an operating system for a wider variety of computer hardware than any other operating system including desktop computers, super computers, mainframes, and embedded devices such as cell phones.

Linux is packaged for different uses in Linux distributions which contain the kernel along with a variety of other software packaged tailored to its intended use. Read the rest of this entry →

The UNIX operating system was developed in the 60’s and 70’s by a group of AT & T employees at Bell Labs.  Unix is used by both servers and workstations and is the basis for a wide variety of other operating systems.

The operating system under UNIX consists of many of the utilities listed above along with the master control program which is called the “kernel”.

The kernel helps start and stop programs, handle the file system, take care of other common high level tasks that most programs share and schedule access to hardware to avoid conflicts if two programs try to access the same resource or device simultaneously.

Besides the main kernel, UNIX systems also had micro-kernels which tried to reverse the growing size of kernels and return to a system in which most tasks were completed by smaller utilities. Read the rest of this entry →

As we all know, open source software’s source code is available to the general public for modification or use from its original design or structure free of charge.

One of the famous open source softwares is Linux operating systems.  But open source is not just about access to the source code.  It has free distribution and it does not restrict other software.

Have you ever wonder why you should use open source software?

This article sites the top reasons why you should use open source software.

• First, open source programs are RELIABLE.

Open source software’s source code availability to the public makes the program reliable.

Whenever there is a bug detected, developers or users tried to fix those bugs within a couple of hours, report it to the maintainers of the software and release an updated version.

Users may opt to choose to use the fixed version or the official version (including the fix releases). Read the rest of this entry →

Every computers have an operating system. What is an operating system ? An operating system – commonly referred to as an OS – is a set of computer programs that manage the hardware and software resources of a computer.

The OS processes electronic devices with a rational response to commands that are approved by the system.

At the foundation of all system software, an operating system performs basic tasks like controlling and allocating memory, prioritizing system requests, controlling input and output devices, facilitating the network, and managing files. Read the rest of this entry →
