What is Linux?

Linux is an operating system, such as DOS and OS/2. In many aspects, however, Linux is quite different. First, it's totally free of charge, i.e. you may copy and distribute Linux as often as you want. Second, it offers very stable operation in networking and multi-user environments. Furthermore, the full source code of Linux is available, which allows you to modify it for your own requirements.

Linux was initially developed by Linus Torvalds, a student at the University of Helsinki in Finland. He first developed a small Unix system, called 'Minix'. In 1991 he released version 0.02 of Linux, an improved Minix system. Since that time, a large Linux community grew up and hundreds of developers all over the world are continuously improving and extending the system.

What do I need to get started?

Well, probably you already have all you need.
Basically, Linux runs on every PC. However, you should NOT have uncommon hardware components. Otherwise the installation procedure will become sort of tricky. All you have to do now is to get a Linux distribution either by free downloading (check my Linux links), or by purchasing the software on CD. The latter is more convenient, as it mostly consists of a package including software, manuals, and support. Most Linux distributions offer very easy installation, so even inexperienced users will get Linux running.

Should I change my operating system to Linux?

This question can not be answered universally. It would not make sense to make the step to Linux, if you're lucky with your current operating system. Moreover, be aware that changing a running system is always risky. It can potentially cause destruction of data, problems in converting different file formats, and hardware problems (e.g. scanners). Furthermore, changing your operating system also requires changing the way of thinking, which inevitably will make demands on your time.

No, I don't want to unsell you the idea of installing a new system. It's just the plain truth. However, if you feel comfortable with Linux, it's the greatest system all over the world. Everyone has to figure out himself which operating system does a better job for him.

Linux is running on all my computers, because

It works very stable
I don't have to buy licenses for all my computers
I'm used to be working on a Unix workstation in my job
It allows easy networking (the Internet is entirely based on Unix)
I enjoy programming on OS and networking level
