Q.4: Match the following

| Column A | Column B |
|---------|----------|
| 1. System Software | b. Keyboard |
| 2. Application | a. Application |
| 3. Input Device | c. Mouse |
| 4. Output Device | d. Calculator |
| 5. Storage Device | e. Printer |

Wait! There seems to be confusion in labeling. Let's fix this:

Actually, based on standard classification:

- System Software → Example: Operating System (but here options don’t match perfectly)
- Application → Example: Word Processor, Calculator
- Input Device → Keyboard, Mouse
- Output Device → Monitor, Printer
- Storage Device → Hard Disk, USB Drive

But the given options are:
- a. Application
- b. Keyboard
- c. Mouse
- d. Calculator
- e. Printer

So matching correctly:

1. System Software → Not listed clearly. But if we assume "Application" refers to apps, then System Software might not have a direct match. However, likely there's a typo. If "System Software" means OS, it's not in the list. Perhaps the question meant something else.

Let’s re-evaluate:

Possibly the intended matching is:

| Column A | Column B |
|---------|----------|
| 1. System Software | (No exact match) — possibly missing option |
| 2. Application | d. Calculator |
| 3. Input Device | b. Keyboard OR c. Mouse |
| 4. Output Device | e. Printer |
| 5. Storage Device | (Not listed) |

But since only these options are given, let's assume:

- Application → d. Calculator ✔
- Input Device → b. Keyboard or c. Mouse ✔ (both are input devices)
- Output Device → e. Printer ✔
- Storage Device → None listed
- System Software → Possibly none

But wait — perhaps the labels are mixed up. Let's assume the column B is mislabeled.

Alternatively, maybe the actual matching is:

- 1. System Software → ??? (not listed)
- 2. Application → d. Calculator ✔
- 3. Input Device → b. Keyboard ✔
- 4. Output Device → e. Printer ✔
- 5. Storage Device → ??? (missing)

Since storage device isn't listed, and mouse/keyboard are both input, but only one slot:

Most likely intended:

✔ Correct Matching:
1. System Software → (No match in list) — perhaps error
2. Application → d. Calculator ✔
3. Input Device → b. Keyboard ✔ (or c. Mouse — either is fine)
4. Output Device → e. Printer ✔
5. Storage Device → (none listed)

But if we must pick from available options, then:

Let’s suppose the options are meant to be matched as:

- 1. System Software → (no clear match) — skip
- 2. Application → d. Calculator ✔
- 3. Input Device → b. Keyboard ✔
- 4. Output Device → e. Printer ✔
- 5. Storage Device → (no match)

Alternatively, if “Application” is meant to be “Application Software”, then:

- Application → d. Calculator ✔
- Input Device → b. Keyboard ✔
- Output Device → e. Printer ✔
- Storage Device → (not listed)
- System Software → (not listed)

So unless there's a typo in the worksheet, the best possible matching is:

| Column A | Column B |
|--------|---------|
| 1. System Software | (Not matched) |
| 2. Application | d. Calculator |
| 3. Input Device | b. Keyboard |
| 4. Output Device | e. Printer |
| 5. Storage Device | (Not matched) |

But if you're expected to match only what fits:

Then:

- 2 → d
- 3 → b
- 4 → e

And others cannot be matched.
