Today, I want to dive into a fundamental topic for anyone studying for the ITF+: operating systems. Recently, I watched a video that breaks down this subject, and I would like to share my insights with you.
🖥️ What is an Operating System?
An operating system (OS) is the backbone of your computer, managing hardware resources and providing a user interface. It ensures everything runs smoothly, from your applications to your hardware components.
🛠️ Types of Operating Systems
The video covers the main types of operating systems:
- Windows: Widely used in personal and business environments, known for its user-friendliness.
- macOS: Developed by Apple, offering seamless integration with other Apple products.
- Linux: Open-source and highly customisable, popular in server environments.
- Mobile OS (iOS and Android): Optimised for mobile devices, focusing on touch interfaces and energy efficiency.
🔧 Basic Functions of an OS
Operating systems handle several critical functions:
- File Management: Organising and storing files efficiently.
- Process Management: Managing running applications and multitasking.
- Memory Management: Allocating and managing memory for processes.
- Device Management: Handling input/output devices and their drivers.
📥 Installing and Configuring an OS
The installation process is straightforward but crucial:
- Pre-Installation: Check system requirements and back up data.
- Installation: Use bootable media or network installation methods.
- Configuration: Set up user accounts, system settings, essential software, and security settings.
