Linux is a open source and free software. That means basically that everyone can see and edit the source code, it just must be as free available as it was before.
The free software movement was launched in 1983 with the primary goal of developing free software replacements for the proprietary software. (Free Software Portal). In 1991 Linus Torvalds, a student of informatics, wrote a central component of a new operating system: the Linux Kernel. He offered it for free on the internet and encouraged people to test and improve it.
Free Software is mostly licensed under the GNU General Public License (GNU GPL)
Linux is a Unix-like computer operating system. This means that it is similar to Unix, but written in a different source code.
A core security feature in these systems is the permission system. All files in a typical Unix-style filesystem have permissions set enabling different access to a file. The more security you add, the less ‘friendly’ an OS is to use.
As Unix, Linux uses small, specialized programs working cooperatively, so any Linux distribution contains a large number of individual programs. Almost every program written for Linux has a man page, which documents the command syntax and every command option, and to be universally available. Whatever you want to know, there is a way to find it.
- No license fees to pay: Linux is OpenSource, means everyone can read and change the code to improve it
- Community based
- Gives the user more control over the OS: highly configurable and highly controllable, esp. in background process management
- Less problems with malware like viruses, worms, trojans – a strong aspect for Internet Cafes
- Thousands of different free available programs
- Great power in use for networks and server
- No “let me do this for you” style of computing as proprietary software – longer training period to setup and configure
- Installing new programs is different to MS-Windows. More clicks, but safer.
- Less support for brandnew hardware, due to manufactures, who don’t offer Linux Drivers.
- Programs are work in progress
