What is Linux

Linux

Linux is, in simplest terms, an operating system, assembled under the model of free and open source software development and distribution.  

Operating System

Operating systems are computer programs. An operating system is the first piece of software that the computer executes when you turn the machine on. The operating system loads itself into memory and begins managing the resources available on the computer. It then provides those resources to other applications that the user wants to execute.


To say that Linux is an operating system means that it's meant to be used as an alternative to other operating systems, Windows, Mac OS, MS-DOS, Solaris and others. Linux is not a program like a word processor and is not a set of programs like an office suite. Linux is an interface between computer/server hardware, and the programs which run on it.

Why Linux?

Linux has proven to be a tremendously stable and versatile operating system, particularly as a network server. Its down-time is almost negligible. We can run Linux servers continuously without reboot for many years. There have been cases when Linux servers have been running for more than 3-4 years without re-booting and then only taken down for a brief period for routine maintenance.

Linux is Very successful on many different kinds of devices like Embedded devices, Hand Held Terminals, and there many areas where Linux is moving towards. Desktop and server development continues to grow faster than any other operating system today.

Linux is being installed on the system BIOS of laptop and notebook computers, which will enable users to turn their devices on in a matter of seconds, bringing up a streamlined Linux environment. This environment will have Internet connectivity tools such as a web browser and an e-mail client, allowing users to work on the Internet without having to boot all the way into their device's primary operating system--even if that operating system is Windows.

The growth of cloud computing is a natural fit for Linux, which already runs many of the Internet's web servers. Linux' growth in cloud computing is the well-known success of Linux on supercomputers, both in the high-performance computing (HPC) and high-availability (HA) areas, where academic research in physics and bioengineering, and firms in the financial and energy industries need reliable and scalable computing power to accomplish their goals.
