Operating/System Software: Introduction

1. What is System Software?
System software is a set of programs designed to control and manage computer hardware and provide a platform for running application software. It acts as a bridge between user applications and the physical components of a computer.

2. Operating System (OS): The Core of System Software
An Operating System is the most essential type of system software. It manages hardware, runs applications, handles input/output, manages files, and oversees system security. Without an OS, a computer cannot function.

3. Key Functions of an Operating System

  • Resource Management: Allocates CPU time, memory space, and input/output devices.

  • File Management: Creates, reads, writes, and organizes files and folders on storage devices.

  • Task Management: Manages running processes and allows multitasking (running multiple programs).

  • User Interface: Provides Graphical User Interface (GUI) or Command Line Interface (CLI) for user interaction.

  • Security & Access Control: Protects data with user accounts, passwords, and permissions.

  • Device Management: Controls peripherals like printers, scanners, and storage devices using drivers.

4. Types of Operating Systems

  • Single-User OS: Used in personal computers (e.g., Windows 10, macOS).

  • Multi-User OS: Supports multiple users at once (e.g., UNIX, Linux in server environments).

  • Real-Time OS (RTOS): Responds instantly to inputs, used in robotics or medical systems.

  • Mobile OS: Designed for smartphones and tablets (e.g., Android, iOS).

5. Examples of Popular Operating Systems

  • Windows: Most widely used OS with a user-friendly GUI.

  • macOS: Known for its sleek design, used in Apple computers.

  • Linux: Open-source, highly customizable, popular in education and development.

  • Android & iOS: Dominant in the mobile device market.

6. Importance in Education

  • Teachers and students use OS features like file management, printing, and application launching for daily tasks.

  • Understanding OS helps educators integrate tech tools efficiently into teaching.

  • Enables use of educational software, online platforms, and digital classrooms smoothly.
