The correct answer is To provide the address of a web resource.

Key Points

  • Port number is a component of a URL (Uniform Resource Locator).
  • A URL is used to specify addresses on the World Wide Web.
  • It typically consists of the protocol (such as HTTP or HTTPS), the domain name, and may include a port number, path, query string, and fragment identifier.
  • The port number is used to identify a specific process or service on the server. For example, HTTP typically uses port 80, while HTTPS uses port 443.
  • Including the port number in the URL allows communication with the correct service or application on the server.

 Additional Information

  • A URL can also include a username and password for authentication, although this is less common.
  • The domain name part of the URL can be either an IP address or a human-readable name that is resolved to an IP address via DNS (Domain Name System).
  • The path specifies the exact resource within the domain that the client wants to access.
  • Query strings are used to pass additional parameters to the server, typically in the format of key-value pairs.
  • The fragment identifier is used to point to a specific section within a resource, usually within an HTML document.

Saving the document with a new name

Why this answer is correct

The correct answer is Saving the document with a new name.

Key Points

  • "Create a document" is a fundamental and crucial step within the overall document creation process in MS Word 365.
  • Starting Point:
  • New Document: This is the foundational action. You initiate the document creation process by opening a new, blank Word document. This provides a clean canvas for you to begin typing and formatting your content.
  • Templates: Alternatively, you can start with a pre-designed template. Word 365 offers a vast library of templates for various document types, such as letters, resumes, reports, brochures, and more. These templates provide a structured framework and visual guidance, saving you time and effort in formatting.
  • Content Creation:
  • Typing and Editing: Once you have a blank document or a template, you begin entering your text. This involves typing, editing, and refining your content to convey your message effectively.
  • Formatting: Word 365 provides a rich set of formatting tools to enhance the presentation of your text. You can:
  • Change fonts, font sizes, and colors.
  • Apply bold, italic, and underline styles.
  • Create bulleted and numbered lists.
  • Adjust line spacing and paragraph indentation.
  • Insert images, shapes, and other media.
  • Layout and Design:
  • Page Layout: You can customize the page layout by adjusting margins, column settings, and page orientation (portrait or landscape).
  • Headers and Footers: Add headers and footers to include information like page numbers, document titles, dates, or company logos.
  • Styles: Apply predefined or custom styles to quickly format headings, paragraphs, and other elements consistently throughout your document.
  • Collaboration and Sharing:
  • Collaboration Features: Word 365 facilitates collaboration by allowing multiple users to work on the same document simultaneously.
  • Sharing and Exporting: Once your document is complete, you can easily share it with others by:
  • Saving it to cloud storage (like OneDrive) and sharing the link.
  • Exporting it as a PDF for easy sharing and printing.
  • Sending it as an email attachment.
  • Saving and Version Control:
  • Frequent Saving: Regularly save your work to prevent data loss. Word 365 automatically saves your document periodically, but it's always best to manually save frequently as well.
  • Version History: Word 365 keeps track of previous versions of your document, allowing you to revert to earlier versions if needed.

Question 436

Delhi Police Constable 2023• Computer Awareness• Computer Awareness

Which of the following options is used while printing documents in MS

Word 365, i.e. if we want to print all the pages from 7 till 10, then the printer should print only the 7th, 8th, 9th and 10th pages?

  1. AOption (a)

    Print one sided

  2. BOption (b)

    Collated

  3. COption (c)

    Print Custom Range

  4. DOption (d)

    Orientation

View answer & explanation

Correct answer

Answer: (c)C.

Print Custom Range

Why this answer is correct

The correct answer is Print Custom Range.

Key Points

  • Print Custom Range:
  • This setting allows you to specify the exact pages you want to print within your document.
  • Instead of printing the entire document, you can select a specific range of pages.
  • For example, to print pages 7 through 10, you would enter "7-10" in the "Pages" field of the Print dialog box.
  • This is useful when you only need specific sections or portions of your document.

Additional Information

  • Print One-Sided:
  • This option ensures that each page is printed on only one side of the paper.
  • It's the default setting for most printing jobs.
  • This option is particularly useful when printing on single sheets of paper or if your printer doesn't support double-sided printing.
  • Collated:
  • When printing multiple copies of a document, the "Collated" option arranges the pages in the correct order for each copy.
  • For example, if you're printing two copies of a four-page document, collated printing will produce two sets of pages 1-4, rather than printing all copies of page 1, then all copies of page 2, and so on.
  • Orientation:
  • This setting determines the page layout:
  • Portrait: The page is taller than it is wide (the standard orientation for most documents).
  • Landscape: The page is wider than it is tall (suitable for wide tables, charts, or images).
  • You can choose the orientation that best suits the content of your document.

  3. COption (c)

    We can use labels in email to sort our inbox

  4. DOption (d)

    We can apply multiple labels to a single email.

View answer & explanation

Correct answer

Answer: (a)A.

We cannot use label in email to sort our inbox.

Why this answer is correct

The correct answer is We cannot use label in email to sort our inbox.

Key Points

  • There is no case distinction in email address syntax. In most cases, a server's decision to send or receive an email is unaffected by capitalization. Whether the letters are capitalized or not, they will be delivered.
  • An email prefix plus an email domain, both in allowed formats, make up a valid email address.
  • The prefix is seen to the left of the @ sign. After the @ sign, the domain appears to the right. For instance, "example" is the email prefix, and "mail.com" is the email domain in the address example@mail.com.
  • It is a distinctive signature so anyone with whom you interact can recognize you at any time or location.
  • As a separator char in the syntax analyzer for such systems, spaces are often not included in any URL, domain name (DNS), or email address space systems.

Additional Information

  • A valid email address has four parts:
  • Recipient name (maximum of 64 characters)
  • @ symbol
  • The domain name (maybe a maximum of 253 characters)
  • Top-level domain
  • Email Username- Identifies a specific person or address in a domain.
  • Email Domain Name- Certain number of top-level domains (.com, .org, .info, .de, etc.)
