Why you should use Linux?

• Unlike many single user desktop console based operating systems, Linux is a multi-user, multi-tasking, network enabled operating system accessible from anywhere on the network.
• Multiple users can access a Linux computer remotely, each running their own individual desktop instance, all at the same time.
• The Linux/Unix X-Windows network enabled multi-user windowing system allows full remote access.

  This is a sharp contrast to a single user console based OS which requires the user to be physically present at the computer in order to access his desktop and applications, limiting access to one user at a time.

• The Linux/Unix OS was designed to support remote and secure multi-user access using ssh.
• This gives all Linux/Unix administrators and users a powerful flexible standard remote interface while the automobile is often the primary remote access tool of other OS administrators (i.e. Windows 98 and NT).
• Linux/Unix shell scripts provide a batch scripting capability which can be scheduled, propagated to other systems.
• Future and advanced development is ensured as the source code is available to all. It is studied in universities and institutions worldwide.
• PhD candidates and corporate researchers use Linux to try advanced computing concepts.
• Linux is here to stay; it is getting stronger day by day, and that is good from a technical, financial and economic point of view.
