CYBER SECURITY & ETHICAL HACKING BASIC TO ADVANCED-SERIES 1(BASICS OF COMPUTER HARDWARE)

                                    MODULE 1:  🔐 Basics of Computer Hardware

📖 Introduction:

Welcome to Series 1 of the Cyber Security &Ethical Hacking Basic to Advanced blog. Before we start learning about how to protect computers and networks, we must first understand how computers work from the inside.

In cyber security, we often deal with problems like hacking, system failures, and hardware issues. To fix these problems or prevent them, we must know what each part of a computer does. A strong understanding of computer hardware helps you become more confident and skilled in solving technical issues and spotting threats.

This blog will explain the basic parts of a computer in a simple and clear way. You don’t need to be a computer expert to understand – just read along and you’ll learn step by step.

📚 Topics We Will Cover:

1. 🧩 Motherboard
   The main circuit board that connects all the other parts. It’s like the central road where all data travels.

2. ⚙️ Processor (CPU)
   The brain of the computer. It does all the calculations and runs programs.

3. 🧠 Memory Devices
   RAM and ROM. RAM helps the computer think faster, and ROM stores important instructions.

4. 💾 Storage Devices
   Devices like Hard Drives, SSDs, and USBs where we save files, videos, software, and more.

5. 🎮 Video Technologies
   Graphics cards and display systems. These parts handle how images, videos, and games look on your screen.

6. 🔧 Other Components
   Power supply, cooling fans, ports, keyboard, mouse, and more – all help the system work properly.
