The Linux OS and the Purpose of an Operating System - Linux Online Training

The Linux operating system (a.k.a. OS, kernel) is used on millions of desktop and server systems every day. And now you're going to get some background into what an OS does.

A typical computer system consists of several hardware components, such as processor, memory, circuit boards, hard disk, monitor and keyboard. It is the job of an operating system to allow you to interact with these hardware components and use the

application software programs (word processors, spreadsheets and other programs) installed on the system.

The Linux OS - Here's What The Linux OS Does:

A software component of the OS is used to prepare the hard disk(s) of the system so that the OS can be installed. The OS is then installed on the hard disk(s) and loads into the memory of the system when it boots. Once the OS has booted, it provides access to your hardware components and gives you the capability of running programs.

Application software programs depend on an operating system and take advantage of the services provided by the operating system. These services include the capabilities of creating, saving and printing data files.

Linux is a multitasking OS. It can run and keep track of multiple programs at once. For example, while working on a Linux system you can view a web page, recalculate the formulas in a large spreadsheet, copy a file and print a document, all at the same time!

Linux is also a very robust operating system. It will continue to run the rest of its applications even when a program has “crashed” (a.ka. “hung”).

Linux is also a multiuser OS. More than one person (each at a different computer) can access the same (server) system. A very common example of this occurs when Linux has been installed as a web server and has hundreds of people accessing it at once.
