Introduction Software is a set of instructions designed to perform a defined task and tells the computer how to work. System software and Application software are the two main categories of software. System software works as a linking interface between a hardware device and the end user. It helps to
Introduction In Python, the OS module gives us the means to maintain a connection between python and the operating system. OS module gives us different useful functions that can perform different tasks on the operating system level. Also, it can access any information related Operating System. The OS modules are
Introduction The fork system call is specially used to make a new process that is known as a child process that runs simultaneously with the process that invokes the fork() call. Once a new child process is initiated both processes will run the next instruction after the fork() system call.
Introduction In this article, we will discuss the page replacement algorithm in the operating system. The page replacement algorithm is responsible for deciding which page is required to be replaced if a new page comes in. Page fault The page fault occurs when a running program tries to capture the
Introduction The banker’s algorithm in the operating system is especially used to avoid deadlock and resource allocation problems that basically use the predefined simulation for all the resources. Why this algorithm is named Banker’s algorithm? This algorithm is internally used in the banking system to check whether a
Introduction By allowing one process to use the CPU while another's execution is put on hold (or in a waiting state) due to the lack of a resource like I/O or another, CPU scheduling maximizes the CPU usage. CPU scheduling seeks to improve the system's effectiveness, speed, and fairness.
Introduction Numerous processes—programs now being run—are constantly active in an operating system. The computer's operation depends on each of these processes. It outlines the fundamental task that the system must carry out. Processes execute sequentially. Some resources are needed for these procedures to operate or complete their execution.
