What is a process in operating system? What are the process states?

Definition, Notes, Operating System Concepts, Phases / By / June 3, 2023

Operating systems (OS) play a crucial role in managing and coordinating various aspects of computer systems. One of the fundamental responsibilities of an operating system is process management, which involves creating, scheduling, and controlling processes. Process in Operating System A process can be thought as a program in execution, but a program by itself is …

4 Key Reasons for building Distributed Systems.

Notes, Operating System Concepts, Reasons / By / August 29, 2020

Q. What are the reasons for building distributed systems? Distributed Systems:  Distributed Systems (also loosely coupled systems) are also multiprocessor systems but they will not be sharing clock, memory etc. and will be communicating with each other with high speed buses, telephone lines etc. Processors in distributed systems may vary in size and function and …

7 Different types of operating systems

Notes, Operating System Concepts, Types Of / By / August 29, 2020

Q: What are the different types of operating systems? Briefly describe. Operating systems and computer architecture have had a great influence on each other. As hardware industry started to develop powerful and feature enriched hardware for computers, the operating systems needed to update themselves to harness the power of those hardware. Again, as operating systems …

What is operating system? What are the purposes, goals and roles of operating system.

Definition, Explanation, Notes, Operating System Concepts / By / June 2, 2021

Operating System An operating system is an intermediary program between computer user and the computer hardware. This computer user can also be just another software running on the operating system or another computer or device. So basically, operating systems are computer programs that let other computer programs or humans communicate with the hardware of the …
