What LINUX is all about?
A version of UNIX that has gained popularity because of its stability as an operating system for hosting web servers. Linux is an open source software and is freely available over the Internet. Linux is an open source operating system within the Unix family. Because of its robustness and availability, Linux has won popularity in the open source community and among commercial application developers. This flexibility has enabled Linux to run on everything from handheld and embedded systems to clusters of hundreds of servers.

Facts of linux

A free Unix- type operating system originally created by Linux Torvalds with the assistance of developers around the world.

Linux is an open source operating system within the Unix family

Linux has gained popularity with ISPs as the OS for hosting Web servers.

It is also being considered for some real-time applications. Compared to a dedicated real-time operating system like QNX.

The full distribution of Linux along with technical support and training are available for a fee from vendors such as Red Hat Software and Caldera.

IBM has adopted Linux as a standard.

It, like Windows, supports a GUI (Graphic User Interface).

Linux features

Stability: Linux doesn’t need to be rebooted periodically to maintain performance levels. It doesn’t freeze up or slow down over time due to memory leaks and such.

Performance: Linux provides persistent high performance on workstations and on networks. It can handle unusually large numbers of users simultaneously.

Network friendliness: Linux was developed by a group of programmers over the Internet and has therefore strong support for network functionality; client and server systems can be easily set up on any computer running Linux.

Flexibility: Linux can be used for high performance server applications, desktop applications, and embedded systems.

Compatibility: It runs all common Unix software packages and can process all common file formats.

Fast and easy installation: Most Linux distributions come with user-friendly installation and setup programs.

Multitasking: Linux is designed to do many things at the same time; e.g., a large printing job in the background won’t slow down your other work.

Security: Linux is one of the most secure operating systems. “Walls” and flexible file access permission systems prevent access by unwanted visitors or viruses.

Open source: If you develop software that requires knowledge or modification of the operating system code, Linux source code is at your fingertips.
