OPERATING SYSTEM1. The operating system is the most importantprogramthatrunson a computer. Every general-purpose computer must have an operating system to run other programs andapplications. Operating systems perform basic tasks, such as recognizinginputfrom thekeyboard, sendingoutputto thedisplay screen, keeping track offilesanddirectorieson thedisk, and controllingperipheral devicessuch asdisk drivesandprinters.For large systems, the operating system has even greater responsibilities and powers. It is like a traffic cop -- it makes sure that different programs andusersrunning at the same time do not interfere with each other. The operating system is also responsible forsecurity, ensuring that unauthorized users do notaccessthe system.

2. Operating systems provide asoftwareplatformon top of which other programs, calledapplicationprograms,can run. The application programs must be written to run on top of a particular operating system. Your choice of operating system, therefore, determines to a great extent the applications you can run. ForPCs, the most popular operating systems are DOS,OS/2, andWindows, but others are available, such asLinux.3. As a user, you normally interact with the operating system through a set ofcommands. For example, the DOS operating system contains commands such as COPY and RENAME forcopyingfiles and changing thenamesof files, respectively. The commands are accepted andexecutedby a part of the operating system called the command processoror command line interpreter.Graphical user interfacesallow you to enter commands by pointing andclickingatobjectsthat appear on the screen.4. LINUX AND GNU Meanwhile, the Linux kernel originated in 1991 as a side project ofLinus Torvalds, while a university student in Finland. He posted information about his project on a newsgroup for computer students and programmers, and received support and assistance from volunteers who succeeded in creating a complete and functional kernel. GNU programmers joint the effort and both groups worked to integrate the finished GNU parts with the Linux kernel to create a complete operating system. (Android, a popular mobile operating system using the Linux kernel)
