The Linux operating system has become a viable alternative for anyone with a PC. It brings all the power and flexibility of a Unix workstation, as well as complete set of Internet applications and fully functional Desktop Interface. 

For the Internet, Linux has become a platform for very powerful Internet applications. Not only you can use the Internet, but with Linux become a part of it, creating your own web, Ftp, Gopher & WAIS sites. Other users can access your Linux system, several at the same time, using different services.

Linux is a fully functional Unix operating system that has all the standard features of powerful Unix systems. There are shells for managing your commands. Linux uses two of the more advanced Unix shells. The Bourne Again Shell (Bash) and the TCSH shell. Each supports a complete shell programming language that you can use to create your own shell scripts.

Linux has the same level of system administration features that you find on standard Unix systems. It has the same multi-user and multitasking capabilities. You can setup accounts for different users and each can access your system at the same time. Each users can have several programs running concurrently. With Linux you can control access setup n/w connections and install new devices.

Linux also have very powerful development tools for creating your own Linux applications. These include the GNU C compiler with a large numbers of programming tools such as debuggers and revision managers. With the shell programming capabilities of different shells, you can create your own Linux commands.

Linux can be generally divided into four major components: the Kernel, the Shell, File structure, and the Utilities. The kernel is the core program that runs programs and manages hardware devices such as disks and printers. The shell provides an interface for the user. It receives commands from the user and sends those commands to the kernel for the execution. The file structure organizes the way files are stored on a storage device such as a disk. Files are organized into directories. Each directory may contain any number of subdirectories each holding files.

The above was the simple Introduction of the Linux Os and its overview. Because it's a Freely distributed OS, it sometimes give people the mistaken impression that it is somehow less than a professional operating system, but we think it is not, rather it is a more powerful and stable OS.
