What are the main functions of Unix and Linux ?
The main difference between Unix and Linux is that Unix is owned by a company (SCO, I believe) and costs a lot to buy, and Linux can be downloaded, installed, and even resolod for free.





The advantages to using both Linux and Unix are that they separate the functions that an ordinary user can perform, versus what a "system" user can perform (it's more complicated than that, but you get the picture). This means that an ordinary user cannot install a virus which affects another person, for example, or delete everything on the machine by accident.





Linux has an advantage over Unix, in that it is Open Source. What this means, is that hundreds of people around the world have written programs that you can use /for free/.


An example of the benefit of this is that from a freshly installed distribution of Linux, you will usually have a high quality graphics program (Gimp), an ISO-rated office suite (OpenOffice.org), and many other tools. In Windows, by comparison, after spending your hundreds of dollars (or whatever) on the operating system, you now have a computer which you can use to ...play freecell.





As for user-friendly - that is a matter of opinion. Admittedly, it has been very difficult to use in the past. I've been using Linux since RedHat 5, which was released some time in the last century.


Personally, I've been impressed by the usability of Mandrake, Suse, Kubuntu and Fedora. I currently use Fedora Core 6 on all my machines.
Reply:this is a big question. answer won't fit here. you might want to google for "UNIX vs Linux" and follow the results





cheers,
Reply:This is indeed a large topic of discussion. However we can boil it down to this. Linux is a child of Unix. There are a number of different variations on Unix as there are linux. Linux primarly was developed by one guy who wanted the same features with a much smaller footprint, and that could run on just about anything. With that said Unix is primarily used on high-end enterprise servers that require high availability and stability. Unix predates windows and as such has much respect and a strong user base.








If you are trying to choose between a Unix flavor and Linux flavor. Linux is your choice. You'll find the most support both hardware and user groups(tech) support. There are a number of different flavors (versions) of Linux, produced by different vendors. There are pros and cons to each distribution, but in essence they are all the same.





I would suggest starting with Ubuntu. It's one of the easiest distros to get running right out of the box. It will install with GNOME as your desktop manager.... Just check out the site and do some research. You'll like what you see.
