Operating System | PDF When a command/process is running in the foreground and is taking a lot of time, no other processes can be run or started because the prompt would not be available until the program finishes processing and comes out. When loading a new process for execution: we create its address space (e.g. page tables, etc), but mark all ptes as either “invalid” or “non resident”; and then add its process control block (pcb) to the ready queue. Components of computer system: in general, we can divide a computer system into the following four components. The document discusses the role and types of operating systems. it describes the main roles of an operating system as memory management, processor management, device management, file management, security, system performance control, job accounting, and error detection.

A comprehensive bca course covering all key units of operating systems notes, from process management and memory allocation to file systems, scheduling, and security mechanisms. The operating system has two objectives such as: firstly, an operating system controls the computer’s hardware. the second objective is to provide an interactive interface to the user and interpret commands so that it can communicate with the hardware. What is an operating system? a program that acts as an intermediary between a user of a computer and the computer hardware. an operating system is a collection of system programs that together control the operations of a computer system. An operating system (os) is an interface between a computer user and computer hardware. an operating system is a software which performs all the basic tasks like file management, memory management, process management, handling input and output, and controlling peripheral devices such as disk drives and printers.
