A computer is an electronic device that helps you perform many tasks by processing information. It takes input (like when you type or click), processes it, and then shows the result on the screen. Computers are powerful tools used for work, learning, entertainment, and communication.

Whether you want to write documents, send emails, watch videos, or run a business, understanding how a computer works is the first step.

Difference between Computer, Laptop, and Mobile

• Computer (Desktop): A desktop computer usually stays in one place — like on your desk at home or office. It consists of separate parts: the CPU (Central Processing Unit), monitor (screen), keyboard, and mouse. Desktops are powerful and good for heavy work but are not portable.

• Laptop: A laptop is a portable computer with all parts built into one device — screen, keyboard, CPU, and battery. You can carry it anywhere and work on the go. Laptops are lighter and smaller but may cost more than desktops with similar power.

• Mobile (Smartphone): A mobile phone is smaller and designed mainly for communication — calling, messaging, and apps. While smartphones can do many things, they have limited screen size and less power compared to computers or laptops. For serious work and learning, a computer or laptop is recommended.

Types of Computers

1. Desktop Computer: Usually consists of separate components: monitor, CPU box, keyboard, and mouse. It requires a power outlet and is ideal for long hours of work.

2. Laptop Computer: Portable and all-in-one, with a built-in screen, keyboard, and battery. You can work anywhere with ease.

3. Tablet: A tablet is a touchscreen device, larger than a phone but smaller than a laptop. It’s easy to carry and good for reading or watching videos, but typing and some tasks can be challenging without extra accessories.

Introduction to Keyboard, Mouse, Monitor, CPU, and Other Basic Parts

• Keyboard: This is where you type letters, numbers, and commands. It looks like a typewriter but has special keys for different tasks. Learning to use the keyboard is essential because it helps you write emails, documents, and search online.

• Mouse: The mouse is a small device you hold in your hand. Moving it moves the cursor (pointer) on the screen. You use the mouse to click on icons, open programs, drag files, and more.

• Monitor: The monitor is the screen where you see everything — text, pictures, videos, and programs. It’s like a TV but only for your computer.

• CPU (Central Processing Unit): Often called the “brain” of the computer, the CPU processes all instructions and runs the software. In desktops, the CPU is usually a separate box connected to the monitor and keyboard. In laptops, it’s built inside the device.

• Other Accessories: Printers to print documents, speakers for sound, webcams for video calls, and external drives for extra storage.

Turning On/Off the System Properly

Knowing how to switch your computer or laptop on and off correctly is very important to keep it safe and working well.

Turning On:

1. Make sure the computer or laptop is plugged into power (if it’s not a battery-operated laptop).

2. Find the power button — it usually has a circle with a line symbol on it.

3. Press the power button once. You will see lights and hear sounds as the system starts.

4. Wait patiently as the computer loads the operating system (like Windows). Soon, you will see the desktop screen.

Turning Off:

1. Do not just press the power button to switch off unless your computer is frozen.

2. Click on the “Start” menu on your screen.

3. Choose the “Power” or “Shut down” option.

4. Wait until the screen goes completely black and the system is off.

5. Then, you can safely unplug or close your laptop.

Properly turning off your system helps protect your files and prevents damage to the computer.

This completes Module 1 — a beginner-friendly introduction to computers and their basic parts, along with safe handling tips.

When you turn on your computer or smartphone, the first thing that starts running is the Operating System (OS). It’s the system software that manages your device’s hardware and allows you to interact with programs like Google Chrome, MS Word, and more.

Think of the operating system like a manager. It helps different parts of the computer work together and ensures you can do your work smoothly.

What is Windows, Android, and macOS?

Let’s understand the 3 most commonly used operating systems:

✅ Windows (by Microsoft):

• Used in most laptops and desktop computers.

• Easy to use with a graphical interface (icons, folders, buttons).

• Popular versions include Windows 10 and Windows 11.

• You'll see a Start Menu, a Taskbar at the bottom, and icons like “My Computer,” “Recycle Bin,” etc.

✅ Android (by Google):

• Mainly used in mobile phones and tablets.

• All Android phones have apps, Google Play Store, and a swipe-based interface.

• It’s not used on laptops or desktops (unless using an emulator).

✅ macOS (by Apple):

• Found only in Apple computers like MacBook and iMac.

• Very smooth and clean design.

• Instead of “Start Menu,” it has a “Dock” at the bottom.

• Used by people in design, media, or those who prefer Apple’s environment.

For this course, we'll mostly work with Windows since it’s the most common for beginners and widely used in business environments.

How to Create Folders, Copy/Paste Files

Once you start using your computer, you’ll want to keep things organized. That’s where folders come in. You can keep your documents, pictures, and files inside folders — just like you keep papers in physical files.

📁 How to Create a Folder:

1. Right-click anywhere on the desktop or inside any file window (like "Documents").

2. Select New → Folder.

3. A new folder will appear named "New Folder".

• Ctrl + Z to undo an action

Organizing your data using folders and files helps you work faster and smarter.

Using Notepad, Calculator, Paint

Your computer already comes with some simple and useful applications (called "built-in software"). These are great for learning the basics.

📝 Notepad:

• A simple text editor where you can write anything — notes, lists, phone numbers, or ideas.

• Open by clicking Start → Search → Notepad.

• Type your content and click File → Save As to store it.

• Choose the location (like Desktop or Documents) and name the file.

This is a great way to learn typing, saving files, and building confidence.

🧮 Calculator:

• Helps you do basic calculations — addition, subtraction, multiplication, and division.

• Go to Start → Search → Calculator.

• Use it just like a regular calculator.

It’s useful for business calculations, pricing, and monthly budgeting.

🎨 Paint:

• A fun and creative tool where you can draw or edit pictures.

• Good for learning mouse control.

• Go to Start → Search → Paint.

• Use tools like pencil, brush, shapes, text, and color fill.

• You can also paste screenshots here and save them.

Many students and beginners love Paint because it builds creativity and helps understand mouse functions.

By completing this module, you now understand:

• What operating systems are.
