Solution:

Web services are online services accessed through the internet, such as the Diksha portal, email, and online banking. Bluetooth is a local wireless communication technology, not an internet-based service.

Question 5:

Which of the following is not an attribute of the <font> tag?

(1) face
(2) height
(3) size
(4) color

Correct Answer: (2) height
Solution:

The <font> tag in HTML supports attributes like face, size, and color, but height is not a valid attribute for the <font> tag.

The <font> tag is now outdated in modern HTML. It's better to use CSS for styling text and elements.

Question 6:

In HTML, we start a comment using:

(1)
(3) --!>
(4) <--!

Correct Answer: (1) . Comments are helpful for explaining your code and are ignored by the browser.

Use comments in your HTML code to leave notes or explain complex sections of your code. This helps you and others understand it better.

Question 7:

Which of the following elements have both the opening and the closing tags in HTML?

(1) <br>
(2) <h1>
(3) <hr>
(4) <img>

Correct Answer: (2) <h1>
Solution:

The <h1> tag is used to define headings and it requires both an opening and a closing tag. Tags like <br> (line break), <hr> (horizontal rule), and <img> (image) are self-closing.

Heading tags like <h1> to <h6> always require closing tags. Self-closing tags like <br> do not.

Question 8:

The default color of vlink is:

(1) Green
(2) Purple
(3) Blue
(4) Yellow

Correct Answer: (2) Purple
Solution:

(A) <dt>
(B) <dl>
(C) <td>
(D) <dd>

Correct Answer: (C) <td>
Solution:

- <dl> is the tag used for creating a description list.
- <dt> is used to define the term in a description list.
- <dd> is used to describe the term in a description list.
- <td> is used for defining table data, not for description lists.

<td> is used in tables, not in description lists! In description lists, you use <dl>, <dt>, and <dd> to list terms and their descriptions.

Question 10:

Which of the following is not an example of an Open Source Software?

(A) Linux
(B) Android
(C) Photoshop
(D) OpenOffice

Correct Answer: (C) Photoshop
Solution:

Photoshop is proprietary software developed by Adobe. This means its source code is not available for public use or modification. On the other hand, Linux, Android, and OpenOffice are open-source software, meaning their source code is freely available and can be modified or distributed by anyone.

Open-source software promotes collaboration and innovation, allowing users to modify and improve the software freely.

Question 11:

Assertion (A): When you enter a query into a search engine, it retrieves and presents a list of web pages, documents, images, videos, or other types of content that are relevant to your search.
Reason (R): The goal of information retrieval is to effectively and efficiently find and present information that matches the user’s search criteria.

(A) Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).
(B) Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of Assertion (A).
(C) Assertion (A) is true, but Reason (R) is false.
(D) Assertion (A) is false, but Reason (R) is true.

Correct Answer: (A) Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).
Solution:

Both the assertion and reason are correct. The search engine retrieves relevant information based on a query, and the reason explains that the goal of information retrieval is to efficiently match search criteria with relevant content. The reason directly supports the assertion.

Information retrieval systems, like search engines, are designed to provide the most relevant results based on the search terms entered by the user.

Question 12:

Assertion (A): It becomes difficult to update and maintain a website’s design using CSS.
Reason (R): CSS allows web developers to separate the presentation layer (styles and layout) from the content layer (HTML).

(A) Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).
(B) Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of Assertion (A).
(C) Assertion (A) is true, but Reason (R) is false.
(D) Assertion (A) is false, but Reason (R) is true.

Correct Answer: (D) Assertion (A) is false, but Reason (R) is true.
Solution:

The assertion is false. In fact, CSS makes it easier to update and maintain a website’s design by separating the layout and styles from the content. This modular approach improves flexibility and ease of updates. The reason is true because CSS separates the design and layout from HTML content, making maintenance simpler.

CSS makes web design more manageable and flexible. By separating styling from content, updating the look of a website becomes easier and more efficient.

Write any two significances of using links in an HTML webpage.

Solution:

Navigation: Links help people move from one page to another on a website.
Improving SEO: Links help search engines understand how different pages are connected, improving search results.

Links are important for both navigation and making sure your webpage is found easily on search engines.

Question 18:

(a) Match the tag with their corresponding correct attribute.

Tags and Attributes:

Tag	Attribute
<table>	border
<input>	type
<ol>	start
<td>	rowspan

Solution:

<table> uses the border attribute to define the table's border.
<input> uses the type attribute to define the input type (e.g., text, radio, checkbox).
<ol> uses the start attribute to define the starting number for an ordered list.
<td> uses the rowspan attribute to specify how many rows the table cell should span.

- border in <table> defines the table’s border.
- rowspan in <td> makes the table cell span multiple rows.

Question 20:

A school wants to create a webpage for the announcement of the orientation programme of its Cultural Club. The school wants all the 3 lines to appear as Headings and Subheadings:

The first line containing its name to have the boldest possible appearance as a heading in Blue color.
The second line containing the Club name should appear as a heading but its size should be smaller than the first line in green color.
The third line containing the Programme details should appear as a heading and its size should be smaller than the previous two lines in Cyan color.

Correct Answer:


<!DOCTYPE html>
<html>
<head>
    <title>Orientation Programme</title>
    <style>
        h1 {
            color: blue;
            font-weight: bold;
            font-size: 36px; /* Largest size for the heading */
        }
        h2 {
            color: green;
            font-size: 28px; /* Smaller than h1 */
        }
        h3 {
            color: cyan;
            font-size: 22px; /* Smaller than h2 */
        }
    </style>
</head>
<body>
    <h1>ABC International School</h1>
    <h2>Cultural Club</h2>
    <h3>Orientation programme on 15th March 2024</h3>
</body>
</html>

Solution:

The HTML code uses three heading tags (<h1>, <h2>, and <h3>) to define the headings for each line. CSS styles are applied to set the colors and sizes as follows:

The <h1> tag is styled with a blue color, bold weight, and the largest font size.
The <h2> tag is styled with a green color and a smaller font size than <h1>.
The <h3> tag is styled with a cyan color and the smallest font size among the three.

Use CSS to style headings by changing their color, font-weight, and font-size. The heading tags (<h1> to <h6>) define the visual hierarchy of content on a webpage.

Question 21:

Ayesha has shot some videos. She wants to create a webpage so as to share her creations with her followers across the world. Help Ayesha to embed her video file in the webpage with the following specifications:

The name of the video file is Ayeshahits.mp4.
The video should play in a window of width 350 pixels and height 250 pixels.
The video controls such as Play, Pause, and Volume should be visible.

Correct Answer:

<!DOCTYPE html>
<html>
<head>
    <title>Ayesha's Video</title>
</head>
<body>
    <h1>Ayesha's Video Creations</h1>
    <video width="350" height="250" controls>
        <source src="Ayeshahits.mp4" type="video/mp4">
        Your browser does not support the video tag.
    </video>
</body>
</html>

Solution:

The <video> tag is used to embed videos into the webpage. The attributes set the following:

width="350" and height="250" set the dimensions of the video player.
The controls attribute ensures that Play, Pause, and Volume buttons are visible.
The <source> tag specifies the video file name (Ayeshahits.mp4) and type (video/mp4).

Use the <video> tag to embed videos, and always include controls for better user experience.

Question 22:

(a) Online Gadgets is an electronic products company. The company wishes to sell its products online for which they want to launch its website. The homepage of the website should contain the images of its products saved as PHONE.JPG and TV.JPG. The company wishes to open the webpage named ALLPHONES.HTML when the image PHONE.JPG is clicked. Similarly, on clicking the image TV.JPG, a different webpage named ALLTVS.HTML should open. Both images should be displayed with a width of 200 pixels and a height of 150 pixels.

Correct Answer:

<!DOCTYPE html>
<html>
<head>
    <title>Online Gadgets</title>
</head>
<body>
    <h1>Welcome to Online Gadgets!</h1>
    <p>Click on the images to explore more products.</p>
    
    <!-- Image for Phones -->
    <a href="ALLPHONES.HTML">
        <img src="PHONE.JPG" alt="Phone" width="200" height="150">
    </a>
    
    <!-- Image for TVs -->
    <a href="ALLTVS.HTML">
        <img src="TV.JPG" alt="TV" width="200" height="150">
    </a>
</body>
</html>

Solution:

The <a> tag is used to create clickable links, and the <img> tag is used to display images. Here's how they work together:

<a href="ALLPHONES.HTML"> makes the PHONE.JPG image clickable, linking it to the ALLPHONES.HTML page.
<a href="ALLTVS.HTML"> makes the TV.JPG image clickable, linking it to the ALLTVS.HTML page.
width="200" and height="150" set the size of both images.

Use the <a> tag with an <img> tag inside to create clickable images that link to other webpages.

Question 23:

Explain the term “Plagiarism.” Write in brief any two examples to illustrate acts of Plagiarism.

Correct Answer: Definition of Plagiarism:

Plagiarism is the act of using someone else’s work, ideas, or words without giving proper credit and presenting it as one’s own. It is considered unethical and a form of intellectual theft. Plagiarism can occur in various forms, such as copying text, images, or code without attribution, or paraphrasing content without acknowledging the source.

Examples of Plagiarism:

Copying Text Without Citation: A student copies paragraphs from an online article or a book and pastes it into their assignment without mentioning the source. This act is plagiarism because the original author is not credited for their work.
Submitting Someone Else’s Work: A student submits a friend’s project, essay, or code as their own. Even if the friend has given permission, this act is plagiarism because the original creator is not acknowledged, and the work is falsely presented as the student’s own.

Solution:

Plagiarism is a serious offense in academics, research, and professional settings. It not only disrespects the original creator’s effort but can also lead to penalties like failing grades, damaged reputation, or even legal consequences.

Always give proper credit to the original author by using citations and references. Tools like plagiarism checkers can help ensure your work is original and properly cited.

Question 24:

(a) Write the HTML code to design a Student’s Data input form as shown below.

Correct Answer:

<!DOCTYPE html>
<html>
<head>
    <title>Student Data Input Form</title>
</head>
<body>
    <h1>Student Data Input Form</h1>
    <form>
        <!-- Name Input -->
        <label for="name">Name:</label>
        <input type="text" id="name" name="name"><br><br>

        <!-- Newsletter Checkbox -->
        <label for="newsletter">Subscribe for Newsletter:</label>
        <input type="checkbox" id="newsletter" name="newsletter"><br><br>

        <!-- Gender Radio Buttons -->
        <label>Gender:</label><br>
        <input type="radio" id="male" name="gender" value="Male">
        <label for="male">Male</label><br>
        <input type="radio" id="female" name="gender" value="Female">
        <label for="female">Female</label><br>
        <input type="radio" id="other" name="gender" value="Other">
        <label for="other">Other</label><br><br>

        <!-- Country Dropdown -->
        <label for="country">Country:</label>
        <select id="country" name="country">
            <option value="USA">USA</option>
            <option value="Canada">Canada</option>
            <option value="UK">UK</option>
            <option value="Australia">Australia</option>
        </select><br><br>
    </form>
</body>
</html>

Solution:

The HTML code uses:

The <input type="text"> element to create a textbox for the name.
The <input type="checkbox"> element to create a checkbox for subscribing to the newsletter.
The <input type="radio"> element grouped by the name attribute to create radio buttons for gender selection.
The <select> element with <option> tags to create a dropdown list for country selection.

Use <label> tags with for attributes to link labels to form elements for better accessibility and usability.

(b) Observe the screenshot of the following content in a webpage and write the HTML code to generate the desired output.

Correct Answer:

<!DOCTYPE html>
<html>
<head>
    <title>Details Table</title>
</head>
<body>
    <h2>DETAILS</h2>
    <table border="1">
        <tr>
            <th>ACTIVITY</th>
            <th>MEMBER NAME</th>
            <th>AGE</th>
            <th>Email</th>
        </tr>
        <tr>
            <td>Chess Club</td>
            <td>John Doe</td>
            <td>28</td>
            <td>john.doe@example.com</td>
        </tr>
        <tr>
            <td>Photography Club</td>
            <td>Jane Smith</td>
            <td>24</td>
            <td>jane.smith@example.com</td>
        </tr>
        <tr>
            <td>Football Club</td>
            <td>Michael Johnson</td>
            <td>31</td>
            <td>michael.johnson@example.com</td>
        </tr>
    </table>
</body>
</html>

Solution:

The HTML code uses the following:

The <table> tag creates the table structure, and the border="1" attribute sets the border size to 1.
The <tr> tag is used to create table rows.
The <th> tag defines header cells for columns like Activity, Member Name, Age, and Email.
The <td> tag defines data cells for individual rows and columns.

Use <th> for table headers to make them bold by default and align them center. Use border="1" in the <table> tag to quickly add a border to the table.
