What else can I help you with?
What operating system will allow you to simultaneously run more programs than the physical memory of the computer will hold?
Any operating system that allows for "paging" or "swapping" is capable of this.
What is Trashing in operating system?
Trashing means excessive page input output in swapping. Which reduces the degree of multiprogramming.
How does an operating system relate to the system software?
The operating system provides a way for the user to manage system hardware and resources while providing a reasonably usable interface for the user to be able to use it.
What is the advantage of swapping in operating system?
Swapping is the one of the efficient regular and authentic approach of memory management. It is the process of swapping of higher priorrity process on the lower priority process. Advantages of swapping are as follows :- 1. higher degree of multiprogramming. 2. dynamic relocation. 3. greater memory utilization. 4. priority based scheduling. 5. less wastage of CPU time. 6. higher performance.
What is the role of operating system and utility software as a component of system software?
Operating system and utility software help the user communicate with computer hardware. They achieve this by providing a user interface and interpreting user instructions for the hardware.
Do all computers need an operating system?
Ovbiously, all computer need an operating system, it's just like the life in the dead body. For interaction between user and computer or between applications and computer , there must exist some interface. Operating system provides that interface to applications by providing an environment to run the applications and providing the hardware resources they need. OS provide interface to users by providing a medium to user to interact with computer.
How would you swap the effects the right and left buttons on the mouse?
You can usually tell the Operating System to perform this task.As it is ultimately the OS who reads and interprets the mouse, swapping mouse buttons is usually a feature provided by the operating system to accommodate left-handed people. You will usually find this in the Mouse or Pointing Devicessection of your operating system's Control Panel. Refer to your operating system's documentation if you need help locating the Control Panel. Note that this answer is generally OS-agnostic. Most operating systems from Windows to MacOS to Linux provide this functionality in generally the same manner.
What does libos mean?
"LibOS" stands for Library Operating System. It refers to an operating system that is implemented largely or entirely as a library linked into a user application, providing flexibility and efficiency by tailoring the operating system services to the specific needs of the application.
What is thrashing with reference to Operating System?
It is a phenomenon in virtual memory schemes when the processor spends most of its time swapping pages, rather than executing instructions. This is due to an inordinate number of page faults.
What are four things a operating system does on a computer?
Managing hardware,managing files,providing a user interface and managing applications
What are some jobs that an operating system might do?
Initializing programs. Running drivers. Managing memory. Providing API's to programs.
What is a kernel?
The central module of an operating system. It is the part of the operating system that loads first, and it remains in main memory. Because it stays in memory, it is important for the kernel to be as small as possible while still providing all the essential services required by other parts of the operating system and applications. Typically, the kernel is responsible for memory management, process and task management, and disk management. The definition of kernel is "the portion of an OS (Operating System) that is responsible for interacting with the hardware. It is the operating system software that runs in kernel mode on the computer's processor and which provides low-level intelligence for the operating system. In other words, the kernel is the "heart" of an operating system.
