What is an operating system Question Answer?
An operating system is a program that manages the computer hardware. it act as an intermediate between a users of a computer and the computer hardware. It controls and coordinates the use of the hardware among the various application programs for the various users.

It also controls peripherals devices such as monitors, printers, and storage devices….Difference between System Software and Operating System :
| System Software | Operating System |
|---|---|
| It load in main memory whenever required. | It reside in main memory all the time while system is on. |
| It is loaded by operating system. | It reside in main memory all the time while system is on. |
What is paging technique in OS?
In computer operating systems, memory paging is a memory management scheme by which a computer stores and retrieves data from secondary storage for use in main memory. In this scheme, the operating system retrieves data from secondary storage in same-size blocks called pages.
What is starvation OS?
Starvation is the problem that occurs when high priority processes keep executing and low priority processes get blocked for indefinite time. In heavily loaded computer system, a steady stream of higher-priority processes can prevent a low-priority process from ever getting the CPU.
What does OS stand for?

Why paging is used in OS?
Paging is used for faster access to data. When a program needs a page, it is available in the main memory as the OS copies a certain number of pages from your storage device to main memory. Paging allows the physical address space of a process to be noncontiguous.
What are the most common operating system interview questions?
A list of top frequently asked Operating System interview questions and answers are given below. 1) What is an operating system? The operating system is a software program that facilitates computer hardware to communicate and operate with the computer software.
Why does an OS need to be OS specific?
These OS specific interactions are usually called “system calls” and encompass how a user space program interacts with the hardware through the OS completely, they fundamentally differ based on the function of the OS and thus a program that does its work through system calls needs to be OS specific.
Is the operating system the same as the OS?
Yes, an OS will specify a binary interface for how operating system functions are called, and it will also define a file format for executables, but it will also provide an API, in the sense of providing a catalog of functions that can be called by an application to invoke OS services.
Which is an example of software being OS specific?
The system call used to write to the console will vary from OS to OS, so right there is one example of why software is OS specific. printf is a function from the C run time library and in a typical implementation is a fairly complex function. If you google you can find the source for several versions online.
