## Chapter 3
1. What do you call the data and instructions which you enter into the computer?
✔ Input
> *Explanation:* Any information or commands given to the computer by the user (via keyboard, mouse, etc.) is called input.
---
2. Which device is used to enter data into the computer?
✔ Input devices (e.g., Keyboard, Mouse, Scanner)
> *Explanation:* Devices like keyboards, mice, microphones, and scanners are used to feed data/instructions into the computer.
---
3. Which part of a computer works on data?
✔ CPU (Central Processing Unit)
> *Explanation:* The CPU is the “brain” of the computer. It processes all the input data and executes instructions.
---
4. Which device displays the output?
✔ Monitor (or Screen)
> *Explanation:* The monitor visually displays the processed results (output) to the user. Other output devices include printers and speakers.
---
5. Which are the two commonly used output devices?
✔ Monitor and Printer
> *Explanation:* These are the most common — monitor for visual output, printer for hard copy (physical) output.
---
Let’s identify each device:
- a. Monitor → Displays output → ✔ O
- b. Mouse → Used to give input → ✔ I
- c. Printer → Produces physical output → ✔ O
- d. CPU Tower (System Unit) → Contains the CPU → ✔ P
- e. Keyboard → Used to type input → ✔ I
> ✔ Final Answers:
> - a. O
> - b. I
> - c. O
> - d. P
> - e. I

## Chapter 4
1. Which buttons are used to re-size a window?
✔ Minimize, Maximize, and Restore Down buttons (usually found in the top-right corner of a window)
> *Explanation:* These buttons control the size of the window — minimize hides it, maximize makes it full screen, restore down returns it to original size.
---
2. Write the steps to open WordPad.
✔ Steps (Windows OS):
> 1. Click the Start button (Windows logo) at the bottom-left.
> 2. Type “WordPad” in the search bar.
> 3. Click on WordPad from the search results to open it.
> *Alternative:* Press `Win + R`, type `wordpad`, press Enter.
---
3. What makes the computer work when the electricity goes off?
✔ UPS (Uninterruptible Power Supply)
> *Explanation:* A UPS provides temporary battery power to keep the computer running during a power outage, giving time to save work and shut down safely.
---
4. Which button do we click first to shut down the computer?
✔ Start button (then choose Shut Down)
> *Explanation:* In Windows, you click the Start button → then click the Power icon → select “Shut down”.
---
5. Which program makes the computer work?
✔ Operating System (OS) — e.g., Windows, macOS, Linux
> *Explanation:* The OS manages hardware, software, memory, and runs applications. Without an OS, the computer cannot function properly.
---
1. The first screen of windows is called desktop.
✔ T — True. The main screen you see after logging in is called the Desktop.
---
2. Icons are the labelled pictures on the desktop.
✔ T — True. Icons represent files, folders, or programs with small labeled pictures.
---
3. Title bar is located at the bottom of the WordPad window.
✔ F — False. The Title Bar is at the top of the window, showing the document name and program.
---
4. UPS makes the computer work when the electricity goes off.
✔ T — True. As explained earlier, UPS provides backup power.
---
5. When the window is active, it turns blue.
✔ F — False. While older versions of Windows (like XP/Vista) had blue title bars for active windows, modern Windows (10/11) use different colors based on theme/settings. It’s not universally “blue,” and some themes make it white or dark gray. So this statement is not always true — hence False.
> *Note:* This might be context-dependent, but since no specific OS version is mentioned, and color varies, F is the safer answer.
