Input output devices Explained! O Level & IGCSE | P1 | Lecture 15

Описание: In this lecture, I explain Input and Output (I/O) Devices for O Level and IGCSE Computer Science in a clear, exam-focused way.

Understanding I/O devices is important because they allow computers to interact with the real world by sending data into the computer (input) and displaying processed results from the computer (output). In exams, students are often tested on different types of input and output devices and how they work.

This lecture is ideal for students preparing for:
📘 O Level Computer Science (Cambridge 2210) – Paper 1 & 2
📗 IGCSE Computer Science (0478 / 0984) – Paper 1 & 2

🔍 What you’ll learn in this lecture:
✔ What Input and Output devices are
✔ Examples of common input devices such as keyboard, mouse, scanner, microphone, and barcode reader
✔ Examples of output devices such as monitor, printer, speakers, and projector
✔ How devices like barcode readers are used in supermarkets and inventory systems
✔ The difference between input and output devices
✔ Real exam-style examples and explanations

This lecture will help you clearly understand how computers receive data and display results, making Paper 1 & Paper 2 questions easier to solve.
