1. Operating Systems Presentation by Sheikh Iyad Bachelors in Computer Science (1 st Semester) Submitted to: Mrs. Shafiya Ma’am an introduction and overview on the Backbone of Modern Computing

2. Introduction to Operating System An Operating System (OS) is a collection of software that manages computer hardware resources and provides common services for computer programs. The operating system is the most important type of system software in a computer system. The operating System comes with a large number of device drivers that make OS services reachable to the hardware environment. Each and every application present in the system requires the Operating System.

3. Functions of an Operating System The main functions of an Operating System are as follows: Resource Management Process Management Memory Management File Management Device Management User Interface

4. Evolutions of Operating Systems In 1940, an operating system was not included in the creation of the first electrical computer. Early computer users had complete control over the device and wrote programs in pure machine language for every task. 1 st Generation of OS

5. Evolutions of Operating Systems The first operating system (OS) was developed in the early 1950s. it gathers all related jobs into groups or batches and then submits them to the operating system using a storage device to finish all of them. 2 nd Generation of OS

6. Evolutions of Operating Systems The first operating system (OS) was developed in the early 1950s. it gathers all related jobs into groups or batches and then submits them to the operating system using a storage device to finish all of them. 3 rd Generation of OS

7. Types of Operating System Some of the most commonly used types of OS are listed below: Single-User Operating Systems Time-sharing Operating System Distributed Operating System Embedded Operating Systems Real-time Operating System

8. Operating System Architecture An operating system architecture refers to the fundamental structure and design principles of an operating system. It describes how the system manages hardware, memory, processes, and communication. It also manages the interaction between software and hardware components

9. Conclusion and Future Trends As technology evolves, operating systems continue to advance, incorporating innovations like virtualization, cloud computing, and AI integration. These advancements drive efficiency, scalability, and enhanced user experiences, shaping the future of computing. Staying ahead in understanding these trends is essential for leveraging the full potential of modern operating systems.
