What is an Operating System (OS)?

An Operating System (OS) is system software that manages hardware and software resources, providing a user-friendly interface for interaction. It acts as an intermediary between users and computer hardware. Usage of Operating Systems (OS)

1. Process Management – Manages execution of programs, multitasking, and process scheduling.
2. Memory Management – Allocates and deallocates memory space as needed.
3. File System Management – Organizes, stores, retrieves, and secures files.
4. Device Management – Controls and coordinates hardware devices (printers, keyboards, etc.).
5. User Interface – Provides GUI or CLI for user interaction.
6. Security & Access Control – Protects data from unauthorized access.
7. Networking – Manages network communication and internet connectivity.

Types of Operating Systems (OS)

1. Batch Operating System – Processes jobs in batches with minimal user interaction.
2. Time-Sharing OS – Allows multiple users to share resources simultaneously.
3. Distributed OS – Manages a group of networked computers.
4. Real-Time OS (RTOS) – Processes data immediately for time-sensitive applications.
5. Embedded OS – Used in embedded systems like IoT devices, smart appliances, etc.
6. Mobile OS – Designed for smartphones and tablets (e.g., Android, iOS).
7. Network OS – Provides network-based computing capabilities.

Advantages of Operating Systems

• Efficiency & Resource Management – Optimizes CPU and memory usage.
