1. Circle the computer that is a laptop.
✔ Answer: Circle the image on the left — the one that looks like a portable computer with a screen and keyboard attached in one unit.
Explanation: A laptop is a portable personal computer designed for mobile use. It has an integrated screen, keyboard, and trackpad (or mouse) in a single clamshell-style chassis. The image on the right shows a desktop computer, which consists of a separate tower, monitor, keyboard, and mouse.
---
2. What is the function of the monitor?
✔ Answer: The monitor displays visual output from the computer so you can see what you’re doing — like text, images, videos, or programs.
Explanation: Think of the monitor as the “window” into your computer. Without it, you wouldn’t be able to see anything happening inside the system. It’s an output device that shows graphics and information generated by the computer’s processor and graphics card.
---
3. What is the function of the keyboard?
✔ Answer: The keyboard is used to input text, numbers, and commands into the computer.
Explanation: It’s an input device that lets you type letters, numbers, and symbols. You also use it to press special keys (like Ctrl, Alt, Enter, or arrow keys) to control programs or navigate menus.
---
4. What is the function of the mouse?
✔ Answer: The mouse is used to point, click, drag, and select items on the screen.
Explanation: It’s another input device that allows you to move a cursor (pointer) around the screen. You can click buttons to open files, select text, or interact with icons and menus. Some mice also have scroll wheels for navigating up and down pages.
---
5. What is the computer’s hard drive?
✔ Answer: The hard drive is where the computer stores all its data permanently — including the operating system, programs, documents, photos, and music — even when the power is off.
Explanation: Unlike RAM (which is temporary memory), the hard drive holds information long-term. Modern computers often use either a traditional spinning Hard Disk Drive (HDD) or a faster Solid State Drive (SSD), but both serve the same purpose: storing files and software.
---
6. What is an external hard drive?
✔ Answer: An external hard drive is a portable storage device that connects to the computer (usually via USB) to store extra files, back up data, or transfer files between computers.
Explanation: It’s like a “portable version” of your internal hard drive. You can unplug it and take it with you. People use them for backups, storing large media files, or moving data between different computers.
---
7. What is a thumb drive?
✔ Answer: A thumb drive (also called a USB flash drive or jump drive) is a small, portable storage device that plugs into a USB port to save and transfer files.
Explanation: It’s very compact — about the size of your thumb — and doesn’t need any power source. You can plug it into almost any computer, copy files onto it, and then plug it into another computer to access those files. It’s great for quick file transfers or carrying documents on the go.
---
✔ Final Tip for Students: When learning about computer parts, remember:
- Input devices = things you use to put info INTO the computer (keyboard, mouse).
- Output devices = things that show or give info FROM the computer (monitor, printer, speakers).
- Storage devices = things that hold your data (hard drive, SSD, external drive, thumb drive).
