Q220. Which action may be performed on emails waiting in an Outbox?

[SSC CGL Tier-II 2024 cycle, held 20 January 2025]

1. Delete already received messages
2. Manage contacts
3. View archives
4. Edit mail not yet sent

Answer: D. Edit mail not yet sent

Explanation: An Outbox normally holds mail queued for sending and may allow modification before transmission. Received messages, contacts and archives are handled through other folders or dedicated sections.

Q219. Which Windows file extension most often identifies an executable installer?

[SSC CGL Tier-II 2024 cycle, held 20 January 2025]

1. .mp3
2. .exe
3. .jpg
4. .txt

Answer: B. .exe

Explanation: Executable program and installer files on Windows commonly use the EXE extension. MP3 is audio, JPG is an image format, and TXT represents plain text documents rather than executable software.

Q218. Why does a multitasking desktop OS need dynamic memory management?

[SSC CGL Tier-II 2024 cycle, held 20 January 2025]

1. It runs one program only
2. Memory allocation never changes
3. Many processes need changing memory allocations
4. It relies exclusively on fixed memory

Answer: C. Many processes need changing memory allocations

Explanation: Desktop systems run multiple processes whose memory demands vary during execution. Dynamic allocation and protection help manage available memory, whereas simpler embedded environments may have more fixed resource assumptions.

Q217. What does Windows User Account Control do before privileged settings change?

[SSC CGL Tier-II 2024 cycle, held 20 January 2025]

1. Adjust display brightness
2. Perform automatic updates
3. Measure CPU workload
4. Ask for permission or credentials

Answer: D. Ask for permission or credentials

Explanation: User Account Control warns or requests approval when a task requires elevation of permissions. This reduces silent changes to protected settings, rather than measuring performance or acting as an update scheduler.

Q216. Which process is used to verify that digital data has not been altered?

[SSC CGL Tier-II 2024 cycle, held 20 January 2025]

1. Compression
2. Hashing
3. Duplication
4. Caching

Answer: B. Hashing

Explanation: A cryptographic hash can provide a compact digest used to detect unintended or unauthorised changes in data. Compression reduces size; caching speeds access; duplication creates copies rather than proving integrity.

Q215. What is a basic reason to protect computer access with a password?

[SSC CGL Tier-II 2024 cycle, held 20 January 2025]

1. Enable printing
2. Add an authentication barrier
3. Reduce installed applications
4. Improve network signal strength

Answer: B. Add an authentication barrier

Explanation: Passwords are a basic authentication factor that limits casual access to accounts and resources. They do not affect wireless signal strength or automatically prevent all attacks; strong passwords and additional safeguards are important.

Q214. Which behaviour may indicate infection by a computer virus?

[SSC CGL Tier-II 2024 cycle, held 20 January 2025]

1. More free drive space
2. Guaranteed improved security
3. Unexpected errors and slow performance
4. Faster system startup

Answer: C. Unexpected errors and slow performance

Explanation: Unexpected crashes, error messages and unusual slowdowns may indicate malware, although they can also result from benign faults. Checking with reputable security tools is appropriate rather than treating symptoms as conclusive proof.

Q213. What is the chief benefit of inserting and deleting slides in a PowerPoint presentation?

[SSC CGL Tier-II 2024 (held 18 January 2025)]

1. Applying templates separately
2. Automatically embedding multimedia
3. Reorganising and adjusting content
4. Enhancing transition effects

Answer: C. Reorganising and adjusting content

Explanation: Insertion and deletion make it possible to refine a presentation’s structure as topics are added or removed. This keeps the material ordered for its audience. Slide transitions and multimedia features are separate choices that do not depend on this basic organising operation.

Q212. Why would a user apply a PowerPoint template when beginning a presentation?

[SSC CGL Tier-II 2024 (held 18 January 2025)]

1. Consistent professional appearance
2. Automatic addition of every media file
3. Instant creation of interactive quizzes
4. Automatic complex animations

Answer: A. Consistent professional appearance

Explanation: A template gives slides coordinated layouts, fonts, colours and design elements. It helps multiple slides look consistent and saves repetitive formatting effort. The template does not necessarily provide animations, interactive quizzes or automatically chosen multimedia content.

Q211. Which statements are correct?
1. RAM normally loses its contents on power-off.
2. ROM stores fundamental boot-related instructions.

[SSC CGL Tier-II 2024 cycle (held 18 January 2025)]

1. Both statements
2. Neither statement
3. Only statement 2
4. Only statement 1

Answer: A. Both statements

Explanation: Ordinary RAM is volatile, so data must be saved to nonvolatile storage before power is removed. ROM or other nonvolatile firmware stores startup instructions needed for initialisation. These are contrasting roles within a computer’s memory hierarchy.
