Interfaces
GUI or graphical user interface is a form of user interface that allows users to interact with electronic devices through graphical icons and audio indicator such as primary notation, instead of text-based user interfaces, typed command labels or text navigation.CLI stands for Command Line Interface. This type of operating system is used by pro workers. In this type of operating system the user can type commands to the open file, delete file and any other work. This type of operating system is difficult to used by any normal computer user.
Task Scheduling
Management and scheduling are the methods used by the Operating System to assign the resources necessary to do tasks. Timing is everything. All tasks are scheduled and are an intrinsic part of the execution model of a computer system. Scheduling is what makes CPU multitasking possible. Multitasking is the ability to run many applications concurrently, or at the same time.Killing, or ending a process can be done using commands.
Services
Many programs run hidden or in the background. These programs are called services. Services usually start at system boot or when launching an application.
GUI
Operating Systems provide two primary interfaces for the user. The most common interface used by most computer users is called the Graphical User Interface (GUI). This type of interface uses small images that represent commands or programs. These images are called icons. An arrow on the screen that is controlled by the mouse is called a cursor. Clicking a mouse button, sometimes double clicking a mouse button on an icon sends a signal or command to the computer telling it to do something like launching a program.
