Function of an Operating System. This operating system was first developed by … Which is not the function of the Operating System? These programs act as an interface between the hardware, application programs, files and user. A. What happens when the CPU receives an interrupt - It suspends the execution of the running program or process and disables all interrupts of lower priority. Then, OS allocates required memory to load the program and data into RAM. The operating system interacts with a computer's hardware on a basic level, transmitting your commands into language the hardware can interpret. Operating System takes a decision of providing the duration and part of the memory for a process or program. This is primary and cumbersome for most computers, especially regarding the input-output. Different components of windows operating system are as follows: Desktop. Each application including the operating system is provided with a specific UI for effective communication. In other words, we can say that an operating system is a communication link between the user and computer and helps the user to run the application programs. An operating system has to fulfill some basic tasks to operate as an ideal operating system. The operating system performs various activities for memory management are: It keeps track of memory means which part of the memory is in use, and what part of the memory is not in use. Operating system helps to allocate the memory at the time when the process request for memory. Operating system shares the various OS system components like File, Process Memory, I/O device management, etc. The operating system window is the extension of the disk operating system. But every operating system works on some fundamentals which form the base of the operating system. Various application programs along with hardware system are used to perform this work. A file is a collection of related information which is should define by its creator. An interrupt may be sent when an application program terminates or requests certain services from the operating system. The function of an operating system are described below: IO Management; Input/output (IO) is an essential element for the operation of any computer. It also provides mechanisms for synchronization and communication among processes. The on-screen work area that contains windows, icons, menus and dialog boxes is called desktop. The first task, managing the hardware and software resources, is very important, as various programs and input methods compete for the attention of the central processing unit (CPU) and demand memory, storage and input/output (I/O) bandwidth for their own purposes. Takes care of scheduling jobs for execution C. Manages the flow of data and instructions D. All of the above. Operating system (OS), program that manages a computer’s resources, especially the allocation of those resources among other programs. Typical resources include the central processing unit (CPU), computer memory, file storage, input/output (I/O) devices, and network connections. Operating system is the most basic program within the computer system. The OS acts as a platform for all other applications on your machine. A file management system does the following: It connects all system applications which deal with files; In theory a new device, which is controlled in a new manner, should function correctly if a suitable driver is available. If there are multiple recycle bin for a hard disk. An operating system (or 'OS') controls the general operation of a computer, and provides an easy way for us to interact with computers and run applications. Operating systems. An operating system (OS) is the program that, after being initially loaded into the computer by a boot program, manages all of the other application programs in a computer. The function of the device driver is then to translate these operating system mandated function calls into device specific calls. A.

Virus protection is not the function of the operating system Join The Discussion. While every function of Operating System is important to some extent. For example, when the user requests CPU for read/write operation, OS determines the amount of memory required for the program instructions and data. The desktop is the entering point in windows. B. An operating system is a set of programs that lies between applications software and the computer hardware. Basically, a network operating system controls other software and computer hardware to run applications, share resources, protect data and establish communication. Desktop is the first object that appears when windows is started. An operating system is a software component that acts as the core of a computer system and connects your computer and its supported components.
