- 1—system software
- 2the purpose and functionality of systems softwareSystem software controls a computer's internal functioning, chiefly through an operating system, and also controls such peripherals as monitors, printers, and storage devices.
- 3operating systems(∿°○°)∿ flip over for key points
- 4user interfaceThe OS provides a user interface (UI), an environment for the user to interact with the machine. The UI is either graphical or text-based.
- 5memory management/multitaskingmemory management is the function responsible for managing the computer's primary memory. The memory management function keeps track of the status of each memory location, either allocated or free.
Multitask operating systems use more than one CPU to handle system tasks. This requires an operating system that is capable of dividing tasks between multiple processors. While memory swapping and multitasking operating systems are two unrelated techniques, both of them are usually used together in systems. - 6peripheral management and driversPeripherals are hardware devices connected to a computer, such as a monitor, printer, scanner or camera. To operate a peripheral, the operating system uses a program called a device driver . Device drivers contain instructions on how to control a device.
- 7user managementOperating systems also manage users. They allow: individual users to be created and deleted. access levels to be given to users, such as administrator rights or standard user rights. auditing (keeping a log) of files a user creates, accesses, edits and deletes.
- 8file managementFile management is one of the basic and important features of operating system. File management is defined as the process of manipulating files in computer system, it management includes the process of creating, modifying and deleting the files.
