1. Process Types Operating System

2. Process Types Spends more time doing I/O than computations, many short CPU bursts I/O-bound process CPU-bound process Spends more time doing computations; few very long CPU bursts

3. Single-tasking 01 02 03 Processes in OS 04 Real-time Multi-tasking Batch processing

4. Interactive 05 Processes in OS 06 Distributed

5. Single-tasking This type of operating system can only run one process at a time. Examples include older operating systems like MS-DOS. 01

6. Multi-tasking This type of operating system allows multiple processes to run concurrently. They can be either preemptive or cooperative. In preemptive multitasking, the operating system decides when to switch between processes, whereas in cooperative multitasking, processes voluntarily yield control to allow other processes to run. 02

7. Real-time Real-time operating systems prioritize tasks based on timing constraints, ensuring that critical tasks are completed within specified time frames. This is crucial in systems where timing is critical, such as industrial automation, robotics, and certain types of embedded systems. 03

8. Batch processing In batch processing systems, processes are executed in batches without user intervention. Jobs are collected, executed one after another, and the results are provided at the end of the batch. 04

9. Interactive Interactive operating systems provide a user interface for users to interact with the system in real-time. They prioritize user input and provide quick responses to user actions. 05

10. Distributed Distributed operating systems manage resources across multiple computers, treating them as a single, integrated computing environment. Processes can be distributed across these systems for improved performance and fault tolerance. 06
