View answer & explanation

Correct answer

Answer: (b)B.

Print

Why this answer is correct

The correct answer is - Print

Key Points

  • Print Command
  • The Print command is located within the File menu (also known as the Backstage view) and is used to generate a hard copy of a document.
  • It allows users to select a printer, specify the number of copies, and choose specific page ranges.
  • In MS Word, the keyboard shortcut Ctrl + P serves as a quick way to access the Print settings.
  • Before printing, Word displays a Print Preview, which shows exactly how the document will appear on paper.

Additional Information

  • Save
  • This command is used to store the document digitally on a storage device like a hard drive or cloud storage.
  • It ensures that any edits or changes made to the soft copy are preserved for future use.
  • Close
  • The Close command exits the active document window without closing the entire Microsoft Word application.
  • It helps in clearing the workspace when a specific task is finished.
  • Options
  • The Options menu provides access to advanced settings such as Proofing, Display, and Language preferences.
  • It allows for the customization of the Word interface, including the Ribbon and Quick Access Toolbar.
  • Hard Copy vs. Soft Copy
  • A Hard Copy refers to a physical printout of a document on paper.
  • A Soft Copy refers to the digital version of a file viewed on a computer monitor or electronic screen.

Question 902

Delhi Police Head Constable 2025• Computer

When a Word document is opened on a device with different fonts installed, why might the layout look slightly different from the original?

  1. AOption (a)

    Font availability affects how text is rendered and substituted

  2. BOption (b)

    Word always rearranges text randomly on new devices

  3. COption (c)

    The file extension changes automatically

  4. DOption (d)

    The printer settings delete fonts from the document

View answer & explanation

Correct answer

Answer: (a)A.

Font availability affects how text is rendered and substituted

Why this answer is correct

The correct answer is - Font availability affects how text is rendered and substituted

Key Points

  • Font Substitution
  • If a specific font used in a document is not installed on the system, Microsoft Word automatically selects a replacement font that is available.
  • This process, known as font substitution, can lead to variations in how the text appears, as the replacement font may have different visual characteristics.
  • Font Metrics and Spacing
  • Every font has unique font metrics, including character width, height, and spacing (kerning).
  • Even if a substituted font looks similar, its physical dimensions often differ, causing text reflow where lines break at different points, altering the overall layout.
  • Text Rendering Engines
  • The way a device's operating system handles text rendering and anti-aliasing can vary, affecting the crispness and exact positioning of characters.

Additional Information

  • Embedding Fonts
  • To maintain layout consistency, Word allows users to embed fonts directly into the document file.
  • This ensures that the original fonts travel with the file, preventing the need for font substitution on other devices.
  • PDF (Portable Document Format)
  • Exporting a document as a PDF is the standard method to "freeze" the layout, as it preserves fonts and formatting as a fixed graphic representation.
  • Standard Fonts
  • Using standard system fonts (like Arial, Calibri, or Times New Roman) minimizes compatibility issues because these are pre-installed on most operating systems.
  • TrueType and OpenType
  • These are the common formats for scalable fonts; while highly compatible, variations in versions between different OS updates can still cause minor rendering shifts.

Question 903

Delhi Police Head Constable 2025• Computer

What is the key distinction between HTTP and HTTPS When accessing websites?

  1. AOption (a)

    HTTP is used only for images, HTTPS only for text

  2. BOption (b)

    HTTPS includes encryption for secure communication

    while HTTP does not

  3. COption (c)

    HTTP is newer and more secure, HTTPS is older

  4. DOption (d)

    There is no difference; both are identical

View answer & explanation

Correct answer

Answer: (b)B.

HTTPS includes encryption for secure communication

while HTTP does not

Why this answer is correct

The correct answer is - HTTPS includes encryption for secure communication while HTTP does not

Key Points

  • HTTPS (Hypertext Transfer Protocol Secure)
  • HTTPS is the secure version of HTTP, which is the primary protocol used to send data between a web browser and a website.
  • The "S" at the end of HTTPS stands for Secure, indicating that all communications between the browser and the website are encrypted.
  • It uses encryption protocols to secure communications, specifically Transport Layer Security (TLS) or formerly, Secure Sockets Layer (SSL).
  • Unlike HTTP, which sends data as plain text, HTTPS ensures that sensitive information like passwords or credit card numbers cannot be easily intercepted by hackers.

Additional Information

  • Port Numbers
  • HTTP typically uses Port 80 for communication.
  • HTTPS uses Port 443 by default to establish a secure connection.
  • SSL/TLS Certificates
  • To use HTTPS, a website must obtain an SSL/TLS Certificate from a trusted Certificate Authority (CA).
  • These certificates provide authentication, proving to the user that the website they are visiting is legitimate and not a fraudulent site.
  • Data Integrity
  • HTTPS provides data integrity, meaning that the data cannot be modified or corrupted during transfer without being detected.
  • This prevents man-in-the-middle attacks where a third party tries to alter the information being sent.

Question 904

Delhi Police Head Constable 2025• Computer

For what main reason do search engines employ web crawlers, also known as spiders or bots?

  1. AOption (a)

    To manually write content for each website

  2. BOption (b)

    To automatically discover and index new and updated pages across the Web

  3. COption (c)

    To prevent users from accessing any website

  4. DOption (d)

    To manage email attachments

View answer & explanation

Correct answer

Answer: (b)B.

To automatically discover and index new and updated pages across the Web

Why this answer is correct

The correct answer is - To automatically discover and index new and updated pages across the Web

Key Points

  • Web Crawlers
  • Also known as spiders or bots, these are automated software programs that systematically browse the World Wide Web.
  • Their primary function is to discover new content, which includes web pages, images, videos, and PDF documents.
  • They follow hyperlinks from one page to another to build a map of the internet's structure.
  • The data gathered is sent back to the search engine's index, a massive database that stores information for search results.
  • Crawlers ensure search accuracy by identifying updates to existing pages and removing dead links from the database.

Additional Information

  • The Indexing Process
  • After crawling, the search engine processes the page content to understand its keywords and relevance.
  • The Search Index acts like the index at the back of a book, allowing the engine to retrieve results in milliseconds.
  • Robots.txt
  • This is a text file used by website owners to provide instructions to web crawlers.
  • It specifies which parts of a website should be disallowed or excluded from the crawling process to protect private data or save server bandwidth.
  • Crawl Budget
  • Search engines allocate a specific crawl budget to every website, determining how many pages a bot will crawl within a certain timeframe.
  • Factors like site speed and content quality influence how often a crawler visits a specific domain.

Question 905

Delhi Police Head Constable 2025• Computer

Which of the following actions helps maintain the security of an email account on a shared computer?

  1. AOption (a)

    Selecting "Remember me" on the login screen

  2. BOption (b)

    Staying logged in even when away from the computer

  3. COption (c)

    Logging out of the email account and closing the browser after use 

  4. DOption (d)

    Writing the password on a note near the computer

View answer & explanation

Correct answer

Answer: (c)C.

Logging out of the email account and closing the browser after use 

Why this answer is correct

The correct answer is - Logging out of the email account and closing the browser after use

Key Points

  • Session Termination
  • Logging out ensures that the session token stored in the browser is invalidated, preventing any subsequent user from accessing the account without credentials.
  • On a shared computer, failing to log out leaves the active session open, making the account vulnerable to unauthorized access.
  • Closing the browser after logging out provides an additional layer of security by clearing temporary session data.

Additional Information

  • Incognito or Private Browsing
  • Using Incognito Mode prevents the browser from saving browsing history, cookies, or site data locally on the machine.
  • Even when using private modes, it is still necessary to log out manually to ensure the server-side session is closed.
  • "Remember Me" Feature
  • The "Remember me" option saves login credentials in the browser's cache or cookies.
  • On public or shared devices, this feature should never be used as it allows others to log in automatically.
  • Multi-Factor Authentication (MFA)
  • Two-Factor Authentication (2FA) adds security by requiring a second form of identification (like an OTP) beyond just the password.
  • It is highly effective in preventing access even if a password is compromised or a user forgets to log out.
  • Password Security
  • Writing down a password on a physical note near a computer is a major security risk known as "visual hacking."
  • Passwords should be complex and managed through secure digital password managers rather than physical notes.

Question 906

Delhi Police Head Constable 2025• Computer

In the context of saving a workbook for the first time, what does the Save As command allow the user to do?

  1. AOption (a)

    Only print the file

  2. BOption (b)

    Choose a file name and storage location for the workbook

  3. COption (c)

    Change the font of all cells and made changes accordingly

  4. DOption (d)

    Close Excel without saving

View answer & explanation

Correct answer

Answer: (b)B.

Choose a file name and storage location for the workbook

Why this answer is correct

The correct answer is - Choose a file name and storage location for the workbook

Key Points

  • Save As Command
  • When saving a workbook for the first time, the Save As dialog box automatically appears to prompt the user for initial file details.
  • It allows the user to specify a unique file name, which helps in identifying the document later.
  • The command enables the selection of a specific storage location, such as a local hard drive, a USB flash drive, or cloud storage like OneDrive.
  • It also provides the option to choose the file format or extension (e.g., .xlsx, .csv, or .pdf) based on the user's requirements.

Additional Information

  • Difference between Save and Save As
  • Save: Updates the current file with the latest changes without prompting for a name or location if the file has already been saved.
  • Save As: Used to create a duplicate or a new version of an existing file under a different name or in a different format.
  • Keyboard Shortcuts
  • The standard keyboard shortcut for the Save command is Ctrl + S.
  • In Microsoft Excel, the F12 key functions as a direct shortcut to open the Save As dialog box.
  • File Extensions
  • The default file extension for Excel workbooks since the 2007 version is .xlsx.
  • Workbooks that contain Macros must be saved with the .xlsm extension to maintain functionality.

Question 907

Delhi Police Head Constable 2025• Computer

What is a potential risk of renaming an Excel file with a completely unrelated name such as "abc.xlsx" after building a detailed worksheet?

  1. AOption (a)

    The data inside changes automatically

  2. BOption (b)

    It becomes harder to identify the content later

  3. COption (c)

    Excel stops opening the file

  4. DOption (d)

    Formulas are deleted

View answer & explanation

Correct answer

Answer: (b)B.

It becomes harder to identify the content later

Why this answer is correct

The correct answer is - It becomes harder to identify the content later

Key Points

  • Identification and Retrieval
  • Renaming a file with a non-descriptive name like "abc.xlsx" makes it difficult to recognize the subject matter or purpose of the worksheet without opening it.
  • Descriptive filenames act as a primary metadata identifier that helps in locating specific information quickly within a file system.
  • In professional settings, clear naming is a fundamental part of data management to ensure consistency and ease of access.
  • Workflow Efficiency
  • Poor naming conventions lead to reduced productivity as users waste time searching through multiple generic files to find the correct data.
  • Using specific names improves collaborative efficiency, allowing other users to understand the file's content immediately.

Additional Information

  • Excel File Integrity
  • Renaming the prefix of a file (the name before the dot) does not affect the internal data, formulas, or cell formatting.
  • The file remains functional and can be opened by Microsoft Excel as long as the file extension (e.g., .xlsx, .xls, .csv) remains unchanged and compatible.
  • Best Practices for File Naming
  • Experts recommend including dates, version numbers, and keywords in the filename to maintain organization.
  • Avoiding special characters and using underscores or CamelCase can help maintain compatibility across different operating systems.
  • File Extensions
  • The .xlsx extension is the default format for Microsoft Excel 2007 and later versions, based on the Office Open XML standard.
  • Renaming the extension itself (e.g., changing .xlsx to .txt) may cause the file to become unreadable by the application, but renaming the name "abc" does not.

Question 908

Delhi Police Head Constable 2025• Computer

A user wants to insert a new column between existing columns B and C in an Excel worksheet. Which of the following sequences of actions will correctly perform this task?

  1. AOption (a)

    Right click column B and choose Insert; the new column appears to the right of column B

  2. BOption (b)

    Right click column C and choose Insert; the new column appears to the left of column C

  3. COption (c)

    Select column A and press Delete; then type the new column heading

  4. DOption (d)

    Double click between columns B and C; the new column appears automatically

View answer & explanation

Correct answer

Answer: (b)B.

Right click column C and choose Insert; the new column appears to the left of column C

Why this answer is correct

The correct answer is - Right click column C and choose Insert; the new column appears to the left of column C

Key Points

  • Column Insertion Logic
  • In Microsoft Excel, when a user inserts a new column, the application is designed to place it specifically to the left of the currently selected column.
  • To create a gap between existing columns B and C, the user must target Column C as the reference point for the insertion.
  • The process involves interacting with the column header, which is the lettered area at the top of the worksheet.
  • Once Insert is selected from the right-click context menu, the data previously in column C (and all columns to its right) shifts one position to the right.

Additional Information

  • Keyboard Shortcuts
  • A faster way to perform this action is by selecting the column and pressing the Ctrl + Plus (+) key combination on the keyboard.
  • This shortcut bypasses the need for the right-click context menu.
  • Ribbon Interface Method
  • Users can also navigate to the Home tab on the Excel ribbon.
  • Under the Cells group, clicking the arrow next to Insert and choosing Insert Sheet Columns achieves the same result.
  • Inserting Multiple Columns
  • If a user highlights multiple columns (e.g., C, D, and E) and selects insert, Excel will add the equivalent number of blank columns to the left of the selection.
  • Row Insertion Contrast
  • While columns insert to the left, rows in Excel are always inserted above the selected row.

Question 909

Delhi Police Head Constable 2025• Computer

Which action in MS Word can help avoid overwriting a master document while experimenting with major formatting changes?

  1. AOption (a)

    Close without saving and reopen later 

  2. BOption (b)

    Use Save As to create a separate experimental copy

  3. COption (c)

    Change page orientation repeatedly

  4. DOption (d)

    Turn off the Status

View answer & explanation

Correct answer

Answer: (b)B.

Use Save As to create a separate experimental copy

Why this answer is correct

The correct answer is - Use Save As to create a separate experimental copy

Key Points

  • Save As
  • The Save As command allows a user to create a duplicate file with a different name or file path.
  • By using this function, the master document remains in its original state, ensuring that experimental formatting does not permanently alter the source content.
  • It facilitates version control, allowing users to keep multiple iterations of the same project for comparison.
  • This is the most effective way to maintain data integrity when testing complex features like styles, macros, or layout changes.

Additional Information

  • Save vs. Save As
  • The Save command (shortcut Ctrl + S) updates the current file by overwriting the previous version with new changes.
  • The Save As command (shortcut F12 in Windows) opens a dialog box to define a new filename or file format (e.g., .docx to .pdf).
  • AutoSave and Version History
  • In modern MS Word versions (Office 365), AutoSave continuously saves changes to the cloud; if not careful, this can overwrite the master document automatically.
  • Version History allows users to view and restore previous versions of a document stored on OneDrive or SharePoint.
  • Templates
  • To avoid modifying a master layout, users can save a document as a Word Template (.dotx), which opens as a new, unsaved document every time it is used.

The correct answer is Names make formulas more readable.

Key Points

  • Using meaningful names for cells or ranges improves the readability of formulas.
  • Named ranges make formulas easier to understand compared to cell references like A1, B2, etc.
  • For example:
  • =SUM(B2:B10) is less descriptive.
  • =SUM(Sales) is much clearer.
  • This makes formulas easier to create, review, and maintain.

Additional Information

  • Advantages of Named Ranges:
  • Improve formula readability and understanding.
  • Reduce errors in complex formulas.
  • Make debugging and auditing easier.
  • Help in managing large worksheets efficiently.
  • Why Other Options Are Incorrect:
  • Option 1: Names do not affect workbook opening on devices.
  • Option 2: Names do not convert formulas into text.
  • Option 4: Named ranges do not hide the formula bar.
  • Important Points:
  • Named ranges improve clarity and usability.
  • They are especially useful in financial models and large spreadsheets.
