3. What are Pixels? • Pixels are the building blocks of digital images, represented as tiny square units. They determine the resolution and quality of an image. Let's dive into their fascinating world!

4. Basics of Computer Processing Central Processing Unit (CPU) The CPU acts as the brain of the computer, executing instructions and performing calculations. It consists of arithmetic logic units and control units. Memory and Storage Memory, such as RAM, provides temporary storage for data and instructions. Storage devices like hard drives hold long-term data even when the computer is turned off. Operating System The operating system manages computer resources, controls hardware and software interactions, and provides a user-friendly interface.

5. Input and Output Devices Output Devices Input Devices • Monitor • Keyboard • Printer • Mouse • Speakers • Touchscreen • Headphones • Mic

6. Understanding Computer Networks 1 Computer Networks A computer network is a collection of interconnected devices that can share resources and communicate with each other. It forms the backbone of modern communication. 2 Types of Networks Local Area Network (LAN) connects devices within a small area. Wide Area Network (WAN) spans large geographical areas. The internet is the largest network of all! 3 Importance of Network Security With the increasing threat of cyber attacks, network security has become paramount. Measures like firewalls, encryption, and user authentication ensure data protection.

7. Software Essentials • Operating Systems: Manage hardware and software resources, such as Windows, macOS, and Linux. • Applications: Programs that perform specific tasks like word processing, photo editing, and web browsing. • Programming: An introduction to the world of coding and its immense potential to create innovative software solutions.

8. Conclusion 1 Recape of Key Points We covered pixels, computer processing, input/output devices, computer networks, and software essentials. These fundamentals shape our digital experiences. 2 Importance of Computer Basics Understanding computer basics empowers us to navigate the digital world, communicate effectively, and explore endless possibilities.

9. FAQ • 1.What is a pixel and how does it relate to computer graphics? • A pixel (short for picture element) is the smallest unit of a digital image. In computer graphics, pixels are the building blocks used to display visual information on screens. • 2.How does a computer process information? • Computers process information through their central processing units (CPUs). The CPU executes instructions stored in the computer's memory, performing calculations and managing data. • 3.What is RAM, and how does it differ from storage? • RAM (Random Access Memory) is temporary memory that the computer uses to store data that is actively being used or processed. Storage, on the other hand, refers to long-term memory (like hard drives or SSDs) where data is saved even when the computer is turned off. • 4.What is the role of an operating system? • An operating system is software that manages computer hardware and provides services for computer programs. It acts as an intermediary between the user and the computer hardware, facilitating communication and resource management. • 5.How do pixels contribute to display resolution? • Display resolution is determined by the number of pixels on a screen. Higher resolution means more pixels, resulting in sharper and clearer images. Common resolutions include 1080p (1920x1080) and 4K (3840x2160).
