| We saw earlier that each ICT device must have an [[wikipedia:Operating_system|operating system]] (also called system software) to run other applications or programmes. Operating system starts automatically when you turn on the computer, this process is termed [[wikipedia:Booting|booting]]. All the other software to paint, type, listen to music, learn maths etc., are called application software or 'Apps' which work with the system software. We will use the [[wikipedia:Ubuntu_(operating_system)|Ubuntu]] ‘[[wikipedia:Free_and_open-source_software|Free and Open Source Software]]’ (called FOSS in short) operating system for our paper. Operating systems use a program called the Graphical User Interface (GUI, which is pronounced as goo-ee), to access the computer with a mouse. The popular operating systems are Microsoft Windows, GNU/Linux and Mac OSx. You will learn about the functions of an operating system, using an example of '''Ubuntu''' GNU/Linux operating system. With this learning, you can also operate a computer with Windows of Mac operating systems. Since Ubuntu is a FOSS operating system, FOSS applications like Office suite, web browser, educational software can be bundled with Ubuntu GNU/Linux operating system. All these applications will be installed on the computer along with the operating system. | | We saw earlier that each ICT device must have an [[wikipedia:Operating_system|operating system]] (also called system software) to run other applications or programmes.
