Which of these functions is not performed by an operating system

Operating systems A computer cannot function without an operating system unless it is an embedded system. An operating system is a collection or suite of programs that manages and controls the computer. It keeps the details of how this is done hidden from the user. The main functions performed by an operating system are: • file management • process management • hardware management • user interface management Common operating systems include: • Microsoft Windows • macOS • Linux • Android • iOS An operating system is a suite of programs that manages and controls a computer. File management Computers store data on physical devices, such as hard disk drives. Users do not need to know how and where this data is stored physically, they just need a way of finding and managing that data. This is provided by the file management system. All data is stored in files, within folders, within drives. The file management system does this by creating a virtual file structure of the physical components. It is a hierarchical structure starting with the root directory, a bit like an upside-down tree. The file system also assigns metadata to each file including: • date created • date modified • last date accessed • last backup • file creator user ID • access permissions • file size There are several functions that users can perform on files, for example: • create • name/rename • save • copy • move • delete Process management All applications, including web browsers, word processors, spreadshee...

Operating System MCQ Questions And Answers Operating System MCQs : This section focuses on "Basics" of Operating System. These Operating System Multiple Choice Questions (MCQ) should be practiced to improve the OS skills required for various interviews (campus interview, walk-in interview, company interview), placements, entrance exams and other competitive examinations. 1.What is true about OS? A. An operating system (OS) is a collection of software. B. The operating system is a vital component of the system software in a computer system. C. An Operating System (OS) is an interface between a computer user and computer hardware. D. All of the above View Answer Ans : D Explanation: Memory management refers to management of Primary Memory or Main Memory. 5.In multiprogramming environment, the OS decides which process gets the processor when and for how much time. This function is called _____________. A. process scheduling B. process rescheduling C. traffic controller D. Processor Management View Answer Ans : A Explanation: In multiprogramming environment, the OS decides which process gets the processor when and for how much time.

An operating system acts as an intermediary between the user of a computer and computer hardware. The purpose of an operating system is to provide an environment in which a user can execute programs conveniently and efficiently. An operating system is software that manages computer hardware. The hardware must provide appropriate mechanisms to ensure the correct operation of the computer system and to prevent user programs from interfering with the proper operation of the system. Operating System: Definition: • An operating system is a program that controls the execution of application programs and acts as an interface between the user of a computer and the computer hardware. • A more common definition is that the operating system is the one program running at all times on the computer (usually called the kernel), with all else being application programs. • An operating system is concerned with the allocation of resources and services, such as memory, processors, devices, and information. The operating system correspondingly includes programs to manage these resources, such as a traffic controller, a scheduler, a memory management module, I/O programs, and a file system. Features of Operating system: Operating system has the following features: • Convenience: An OS makes a computer more convenient to use. • Efficiency: An OS allows the computer system resources to be used efficiently. • Ability to Evolve: An OS should be constructed in such a way as to permit the effective ...

Computers and Technology Quiz The first Computers acquired more powerful operating systems in the 1960s with the emergence of time-sharing, which required a system to manage multiple users sharing CPU time and terminals. Two early time-sharing systems were CTSS (Compatible Time Sharing System), developed at the The In addition to such general-purpose systems, special-purpose operating systems run on small computers that control assembly lines, aircraft, and even home appliances. They are real-time systems, designed to provide rapid response to
