UNDERSTANDING THE OPERATING SYSTEMAs already mentioned in previous chapters, including the operating systemin the system software is software that plays a role inrun the computer hardware and computer systemoverall.Operating system software is in charge of managingresource use in a computer and provides the interface forusers to access those resources.FUNCTIONThe functions of an operating system in general can be seen inFigure 4.2.User interface xThis function is a function of the most easily recognizable by the userbecause through this function the user can interact with the operating system,hardware or other software. Operating system onBasically waiting for input or instructions from the user and thentranslates these commands in a language understood bycomputer. User interface to be a place for users towrite or deliver the order.
Broadly speaking there are two models of the user interface CommandLine Interface (CLI) and Graphical User Interface (GUI). CLI providesfacilities for users to give commands in text formwhile the GUI is more based on the graphical display. Today nearly allModern operating systems provide a model of the GUI as the user interface.Some provide a GUI that is integrated with the operating system kernel,for example, on Microsoft Windows and Apple Mac OS versions earlier. Whileothers provide a GUI that is modular, that is not integrateddirectly to the operating system kernel, such as Unix, Linux and Mac OSversion X and above.(Click) or two times in a row (double cli
