The OS decides the best way to swap between running, runnable and waiting processes. It controls which process is being executed by the CPU at any point in time, and shares access to the CPU between processes. The job of working out when to swap processes is known as scheduling.
How the operating system helps manage the processor and memory?
As the OS coordinates the activities of the processor, it uses RAM as a temporary storage area for instructions and data the processor needs. The OS is therefore responsible for coordinating the space allocations in RAM to ensure that there is enough space for the waiting instructions and data.
What does the operating system help to manage?
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.
Why does the OS need to manage the processor?
The operating system’s most important job is managing the CPU: If there are multiple programs that must execute, then it is a disaster if one program uses the processor and “loops. ” The OS must ensure that all programs have fair use of the processor’s time so that all programs make progress at execution.
How the operating system helps manage hardware such as the processor memory storage and peripheral devices?
How does the operating system help manage resources such as the processor, memory, storage, hardware, and peripheral devices? When the OS allows you to perform more than one task at a time, it is multitasking. To provide for seamless multitasking, the OS controls the timing of the events on which the processor works.
What are the 5 operating system?
Five of the most common operating systems are Microsoft Windows, Apple macOS, Linux, Android and Apple’s iOS.
Who controls the working of a computer?
The principal system software is the operating system. It manages the hardware, data and program files, and other system resources and provides means for the user to control the computer, generally via a graphical user interface (GUI).
How do you manage a processor?

How is Ram managed?
Memory management is the process of controlling and coordinating computer memory, assigning portions called blocks to various running programs to optimize overall system performance. … Application memory management combines two related tasks, known as allocation and recycling.
How does an OS manage device drivers?
The OS uses programs called device drivers to manage connections with peripherals. handles the translation of requests between a device and the computer. defines where a process must put outgoing data before it can be sent, and where incoming messages will be stored when they are received.
