Unlike UNIX, Linux, which is a clone of UNIX, was designed for individual computer segment and available on free of cost or with a very less cost compared to UNIX operating system.  It has already gained popularity as a replacement operating system to proprietary operating systems like Windows and very efficient and very fast performing system.   Even though windows occupied the number one spot in terms of desktop operating system, Linux has evolved as an alternative to it.  It is also a publicly open and extendible by contributors such as students because it conforms to the Portable Operating System Interface standard user and programming interfaces, software developers can develop applications which can be ported to other OS.  There are many electronic equipment are now equipped with Linux such as Mobile Phones, video games, tablet computers, etc.

As a matter of fact, UNIX and Linux are somehow similar with their file structure, commands, etc.  Some minute differences between them might be how some things are implemented.  You can interchange between them and may not experience any difference at all, except for the drivers such as ATi or NVIDIA display drivers, which are not interchangeable.

Even though over the years many UNIX Kernels have been developed, Linux has emerged as the most successful and useful by far. Some it said that Linux is the Windows of Unix, means how Windows is DOS based and always has DOS in the background.


In the world of information technology, the words UNIX and Linux are famous and most common because of its wide usage across the world.  Both are operating systems and UNIX is the first operating system written in the C language.  It is also a freeware product with lot of extension and new ideas provided by universities and individuals in a variety of versions.  Also, UNIX is used in the workstation products from Silicon Graphics, IBM, Sun and other companies.  Unix environment and client/server program models were important element in the evolution of interent and changing the face of modern computing as centered in the networks rather than on personal computer solutions.
