Chapter 4 - Operating System Basics - Scott Witter




The most basic and fundamental part of a personal computer is the DOS(Desktop Operating System) or NOS(Network Operating System) without it all you have is your power on self-test(POST) and your basic input output(BIOS) system. The operating system acts as the master controller for all activities that take place within a computer system. On top of that operating systems also manages the processors input and output, allocates memory for all the programs and data that are being used, keeps track storage resources so that files and programs can be found and changed, communicates to all peripheral devices, and finally it creates the basic elements of a graphical user interface. To add even more, with each operating system there two types of user interfaces, there is the graphical user interface and a command line interface. The graphical user interface is visually appealing and easy to navigate. The command line user interface is only a command prompt that doesn’t look visually stimulating and performs actions from certain commands that the user enters.
            There are many different types of operating systems: Windows OS, MAC OS, and Linux OS that can be installed on a device. Many people choose Windows over all other operating systems because of its familiarity and its graphical user interface is easy to navigate. Although there are some people who choose to get a MAC OS because of its high graphics and if they are an art student, those artsy fartsy people love MACs so they can edit their “cool” and “hip” photos. For high end work stations and servers Linux would be the way to go because if its stability and it is open source. So which operating system you choose make sure it is the one for you!
