11. Assertion (A) : Blogs are an effective way for individuals to share their thoughts, knowledge, and experiences online.
Reason (R) : Only professional web developers can create and maintain blogs.
(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.

Answer : (C) Assertion (A) is true, but Reason (R) is false.

12. Assertion (A) : The <img> tag will display an image even if the src attribute is not specified.
Reason (R) : The src attribute provides the path to the image file, which is essential for the browser to locate and display the image.
(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.

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

Teacher's Note:
For Assertion-Reason questions, check the Assertion and Reason as two separate factual claims before deciding whether one explains the other.
Know your protocol acronyms cold (TCP/IP, POP3, SMTP, TELNET, FTP) — several Section A marks depend on exact definitions, not just recognition.
Learn the img tag's alt-text fallback behaviour — an image with a broken/missing src still renders the alt attribute area, which is why A12 is false.

SECTION B

13. What is a Software License ? Also mention its purpose.

Answer : A software license is a legal agreement that defines how a user can install, use, and distribute a software program. Its purpose is to protect the rights of the software creator and specify the terms under which the software can be legally used or shared.

Teacher's Note:
Cover both parts clearly — 1 mark for the definition, 1 mark for the purpose.
Mention "legal agreement" and "rights of the creator" — these are the key phrases examiners look for.

14. (a) What is a search engine ? Name any two popular search engines.
OR
(b) Write the expanded form of SMTP. How does SMTP differ from POP3 ?

Answer (a) : A search engine is an online service or software that helps find information on the Internet by entering keywords or phrases, and retrieves/displays matching web pages. Examples (any two): Google, Bing, Yahoo, DuckDuckGo.

Answer (b) : SMTP stands for Simple Mail Transfer Protocol. SMTP is used to send emails, while POP3 (Post Office Protocol version 3) is used to retrieve/download emails to a device; SMTP does not save emails on the user's device, POP3 does.

Teacher's Note:
Attempt only one of (a)/(b) — it's an internal choice, not both.
For (a), naming any two well-known search engines is enough; no need to explain how they work.
For (b), a one-line send-vs-retrieve distinction is the core marking point.

15. Differentiate between a tag and an attribute in HTML with the help of a suitable example.

Answer : A tag is an HTML command that defines and structures an element of a webpage (e.g. <body>...</body>), whereas an attribute provides additional information about a tag and is written inside the tag's angle brackets (e.g. bgcolor in <body bgcolor="red">).

Teacher's Note:
Always illustrate with one concrete example showing a tag AND an attribute together — full marks need the example, not just the definitions.
Keep the distinction crisp: tag = structure/element, attribute = extra property of that element.

16. (a) What is the purpose of <DT> and <DD> tags in a description list ?
OR
(b) Explain the purpose of the following tags :
(i) <P>
(ii) <HR>

Answer (a) : <DT> defines the term or name in a description list. <DD> provides the description or explanation of the term defined by <DT>.

Answer (b) : (i) <P> is used to define a paragraph in HTML. (ii) <HR> is used to create a horizontal rule/line across the page, typically to separate sections of content.

Teacher's Note:
Attempt only one of (a)/(b).
1 mark is awarded per tag, so both parts of whichever option you pick must be answered.

17. What is CSS and why is it used in web designing ?

Answer : CSS stands for Cascading Style Sheets. It is used to control the presentation of a web page — designing colours, fonts, spacing, alignment, positioning, and overall layout, separately from the HTML content.

Teacher's Note:
Writing only the full form (Cascading Style Sheets) earns 1 of the 2 marks — explain its purpose too for full marks.
Emphasize that CSS separates styling from content/structure.

18. (a) Sonal has been given an incomplete HTML code. Help her to complete the code by filling in the blanks as per the mentioned specifications :

<html>
<head>
<style>
p{
__________ : Green; /* Line 1 */
__________ : 12px; /* Line 2 */
__________ : center; /* Line 3 */
color:yellow;
}
__________ { /* Line 4 */
width:50%
}
</style>
</head>
<body>
<p> Saving the environment is crucial for a healthier Earth </p>
<hr>
</body>
</html>

(i) Line 1: Page background colour should be Green.
(ii) Line 2: Font size of the paragraph text should be 12.
(iii) Line 3: Alignment of the paragraph text should be center.
(iv) Line 4: The width of the horizontal ruler should be 50%.

OR

(b) Refer to the incomplete HTML code given below and complete the code based on the specifications provided :

<html>
<head> __________</head> <!-- Line 1 -->
<body>
<h1>My Favourite Fruits<h1>
<ol __________="I" __________="3"> <!-- Line 2 -->
__________ <!-- Line 3 -->
<li>Banana</li>
</ol>
</body>
</html>

(i) Line 1: Set the web page title to 'About Me'.
(ii) Line 2: The ordered list should use uppercase Roman numerals for numbering.
(iii) Line 3: The list should begin with Roman numeral III.
(iv) Line 4: The first list item should be 'Apple'.

Answer (a) :

(i) background-color : Green;
(ii) font-size : 12px;
(iii) text-align : center;
(iv) hr

Answer (b) :

(i) <title>About Me</title>
(ii) <ol type="I" start="3">
(iii) <li>Apple</li>

Teacher's Note:
Attempt only one of (a)/(b).
Each blank is worth ½ mark — fill every one correctly for full marks.
For (b), remember type controls the numbering style and start sets the starting value.

19. What is e-Banking ? Mention one difference between e-Banking and e-Shopping.

Answer : e-Banking (electronic banking) means accessing and using banking services over the Internet. Difference: e-Banking is online banking (transferring money, checking balances), while e-Shopping is buying and selling goods/services through online websites or apps.

Teacher's Note:
A correct definition alone can fetch 1 mark even without the difference — but include both for full 2 marks.
Give one clear point of contrast, not a long list.

SECTION C

20. The following HTML statements are not written properly. Rewrite the correct statements with underlined corrections. The desired purpose of each statement is mentioned under it.
(i) <a link="https://ncert.nic.in/">Click here</a>
<!-- The link should navigate to https://ncert.nic.in -->
(ii) <ul type="O">
<!-- The list should use hollow circle as bullet. -->
(iii) <font color=Arial size=5>My Webpage</font>
<!-- The font should be Arial, and the size of the font should be 5. -->

Answer :

(i) <a href="https://ncert.nic.in/">Click here</a>
(ii) <ul type="circle">
(iii) <face=Arial size=5>My Webpage</font>

Teacher's Note:
1 mark per correction — underline the corrected part as instructed.
Remember: links use href (not link); hollow-circle bullets use type="circle"; the <font> tag's family attribute is face, not color.

21. Answer the following questions :
(i) Write the expanded form of SMS.
(ii) Expand FTP and SFTP. How does SFTP differ from FTP for transferring files ?

Answer :

(i) SMS: Short Message Service.
(ii) FTP: File Transfer Protocol. SFTP: Secure File Transfer Protocol. SFTP encrypts data before sending it over the network, while FTP transfers data without encryption.

Teacher's Note:
Get the exact wording right: "Short" Message Service, not "Smart".
The key SFTP-vs-FTP difference examiners want is encryption/security — lead with that.

22. (a) Ravi has designed a vibrant web page filled with colourful images and festive text to celebrate his friend’s graduation. Help him by writing suitable HTML tag(s) to add a celebratory video to his web page as per the specification given below :
(i) Name of the video file is celebration.mp4.
(ii) The video controls (Play, Pause, Volume, etc.) should be visible.
(iii) The video should automatically start playing when the web page loads.

OR

(b) (i) Explain the significance of linking in HTML.
(ii) Write the appropriate HTML tag with the correct attributes to achieve the following requirements :
• The links that have not been visited should appear in blue.
• The links that have already been visited should appear in purple.

Answer (a) :

<video controls autoplay muted>
<source src="celebration.mp4">
</video>

Answer (b) : (i) Linking in HTML connects web pages and other web resources, letting users navigate easily and making websites interactive.
(ii)

<style>
a:link { color: blue; }
a:visited { color: purple; }
</style>

Teacher's Note:
Attempt only one of (a)/(b).
For (a), autoplay alone isn't enough in modern browsers — pairing it with muted is why the marking scheme's model answer includes muted (though it isn't compulsory for marks).
For (b)(ii), a:link and a:visited are the pseudo-classes examiners are checking for.

23. (a) Write suitable HTML statements to display the following text on a webpage :
(i) H₂O
(ii) E=mc²

(b) Write HTML code to create a hyperlink for sending an email to "help@cbse.gov.in" when the user clicks on the text 'HELP'.

Answer (a) :

(i) H<sub>2</sub>O
(ii) E=mc<sup>2</sup>

Answer (b) :

<a href="mailto:help@cbse.gov.in">HELP</a>

Teacher's Note:
Use <sub> for subscript and <sup> for superscript — both parts of (a) are required for full marks.
For (b), remember the mailto: prefix inside href — without it the link won't open an email client.

SECTION D

24. (a) Write the HTML code to design the webpage with the form as shown below (Flight Reservation Form — Name text box; Seat Type radio buttons: Economy (default selected)/Business; Select Category combo box: Child/Adult/Senior Citizen) :
• Specification 1: The text "Flight Reservation Form" should be in heading level 3.
• Specification 2: There should be a text box to accept the name of the passenger.
• Specification 3: Two radio buttons for seat type (Economy/Business); Economy should be the default selected radio button.
• Specification 4: Passenger's category to be chosen from a combo box having options Child, Adult, and Senior Citizen.

OR

(b) Write the HTML code to design the web page as shown below (My Schedule table — 4 rows × 4 columns: Name/Morning/Noon/Evening headers; Sahil-Running-Self Study-Gym; Abhay-Yoga-Tuition-[Gym, spanned]; Neha-School-[Dancing, spanned across Noon+Evening]) :
• Specification 1: "My Schedule" displayed as a first-level heading; page background colour should be light yellow.
• Specification 2: Use the table header tag for the column headers.
• Specification 3: The table should have exactly 4 rows and 4 columns, first row as table header.
• Specification 4: Use rowspan and colspan wherever required, as shown in the table.

Answer (a) :

<h3>Flight Reservation Form</h3>
<form>
Enter Name : <input type="text">
Seat Type :
<input type="radio" name="SeatType" value="Economy" checked>Economy
<input type="radio" name="SeatType" value="Business">Business
Select Category:
<select id="Category" name="Category">
<option value="Child">Child</option>
<option value="Adult">Adult</option>
<option value="Senior">Senior Citizen</option>
</select>
</form>

Answer (b) :

<body bgcolor="lightyellow">
<h1>My Schedule</h1>
<table border="2">
<tr>
<th>Name</th><th>Morning</th><th>Noon</th><th>Evening</th>
</tr>
<tr>
<td>Sahil</td><td>Running</td><td>Self Study</td><td rowspan="2">Gym</td>
</tr>
<tr>
<td>Abhay</td><td>Yoga</td><td>Tuition</td>
</tr>
<tr>
<td>Neha</td><td colspan="2">School</td><td>Dancing</td>
</tr>
</table>
</body>

Teacher's Note:
Attempt only one of (a)/(b) — this is a single 4-mark question with an internal choice.
For (a), the name/id attributes aren't compulsory for marks, but grouping the two radio buttons under the same name is essential so only one can be selected.
For (b), rowspan merges cells vertically, colspan merges horizontally — match them exactly to the table shown.

SECTION E

Case-Study

25. Dr. Chitra is a Computer Science Professor at a University and was working on a research paper since last few months. She recently submitted her paper to a publication house. A few months after publishing her paper, she found that another researcher has published a similar paper in a different journal, using some portions of her work without giving her credit. Dr. Chitra is upset and wants to take legal action.
Based on the above information, answer the following questions :
(i) Are netiquettes being followed in the given scenario ? Justify your answer.
(ii) The act of using someone’s work as your own is known as __________.
(iii) Which type of intellectual property law was violated by the other researcher by publishing Dr. Chitra’s work without consent ?
(iv) Suggest any one way to prevent intellectual property law violation in the context of academic research.

Answer :

(i) No, netiquettes are not being followed — using someone else's work without giving credit is plagiarism, which is unethical and violates academic integrity.
(ii) Plagiarism.
(iii) Copyright law (Intellectual Property Rights).
(iv) Take permission before using copyrighted material, or cite sources properly.

Teacher's Note:
Justify part (i) in one line — name plagiarism explicitly, that's the value point.
Keep (ii)-(iv) to short, exact terms; no need for long explanations.

26. Irfan lives in a rural area with limited access to the Internet. His children struggle to attend online classes, as the area has poor Internet connectivity. On the other hand, in the nearby city, people have access to high speed Internet and are able to utilize services effectively. Irfan feels that his family is at a disadvantage due to the lack of access to digital infrastructure.
Based on the above information, answer the following questions :
(a) Unequal access to digital technology is called __________.
(b) Mention any one reason for this unequal access to technology.
(c) Mention any one initiative the government can take to reduce this unequal access.
(d) How does limited access to the Internet affect children in terms of education and opportunities ?

Answer :

(a) Digital Divide.
(b) Lack of infrastructure in rural areas (or high cost of technology).
(c) Provide affordable/free internet access in rural areas (or promote digital literacy training).
(d) Limited internet access restricts children from accessing online educational resources, reducing their learning opportunities.

Teacher's Note:
"Digital Divide" is the exact term expected for (a) — write it precisely.
