SECTION A
Q1. Arun is sending an e-mail to his office. Which protocol out of the following options will be used for the purpose ? [1 mark]
(A) FTP
(B) HTTP
(C) SMTP
(D) SCP
Answer: (C) SMTP
SMTP (Simple Mail Transfer Protocol) is the protocol used for sending emails. When Arun sends an email to his office, SMTP is responsible for transmitting the email from his client to the mail server and then to the recipient's mail server.
FTP is used for file transfer, HTTP is used for web browsing, and SCP is used for secure file copying, so these are not appropriate for sending emails.
Teacher's Note:
1) SMTP is specifically for sending emails; POP3/IMAP are for receiving.
2) Remember the key protocols: FTP (files), HTTP (web), SMTP (send mail), POP3/IMAP (receive mail).
3) This is a straightforward protocol identification question—no calculation needed.
Q2. Which of the following is not an e-Reservation portal in India ? [1 mark]
(A) https://www.amazon.in
(B) https://www.yatra.com
(C) https://www.makemytrip.com
(D) https://www.irctc.co.in
Answer: (A) https://www.amazon.in
Amazon.in is an e-commerce portal for shopping, not an e-Reservation portal. The other three options are all e-Reservation portals in India:
1) Yatra.com – for flight and hotel reservations
2) MakeMyTrip.com – for travel and hotel bookings
3) IRCTC.co.in – Indian Railways official portal for train reservations
Amazon.in is used for purchasing goods and products, not for reserving travel or accommodation services.
Teacher's Note:
1) Distinguish between e-commerce portals (shopping) and e-Reservation portals (booking travel/accommodation).
2) IRCTC, Yatra, and MakeMyTrip are all recognized government or major travel booking platforms.
3) Amazon is a general e-commerce marketplace, not a reservation service.
Q3. Which of the following attributes is not a valid attribute of the <font> tag in HTML ? [1 mark]
(A) face
(B) type
(C) size
(D) color
Answer: (B) type
The <font> tag in HTML has three valid attributes:
1) face – specifies the font family/typeface
2) size – specifies the size of the font
3) color – specifies the color of the text
The type attribute is not a valid attribute of the <font> tag. Note that the <font> tag is deprecated in modern HTML and CSS is preferred for styling.
Teacher's Note:
1) Valid <font> attributes are: face, size, and color only.
2) The <font> tag is deprecated—use CSS styling instead in modern practice.
3) type attribute is used with other tags like <input> and <script>, not <font>.
Q4. What is the full form of FTP ? [1 mark]
(A) File Transfer Protocol
(B) File Transmission Protocol
(C) Fast Transfer Protocol
(D) Fast Transmission Protocol
Answer: (A) File Transfer Protocol
FTP stands for File Transfer Protocol. It is a standard network protocol used to transfer files between computers on a network. FTP allows users to upload and download files from a server using commands through an FTP client, making it one of the oldest and most widely used protocols for file transfer over the internet.
Teacher's Note:
1) FTP = File Transfer Protocol—a foundational internet protocol for file exchange.
2) Key distinction: Transfer (not Transmission), File (not Fast).
3) FTP typically uses port 21 and operates in active or passive mode—basic knowledge for IT exams.
Q5. Which of the following attributes is not a valid attribute of the <body> tag in HTML ? [1 mark]
(A) text
(B) background
(C) bgcolor
(D) width
Answer: (D) width
The <body> tag in HTML supports several attributes like text (to set text color), background (to set a background image), and bgcolor (to set background color). However, width is not a valid attribute of the <body> tag. The width of a page body is controlled through CSS styling, not through an HTML attribute.
Teacher's Note:
1) Know the valid HTML attributes for the <body> tag: text, background, bgcolor, link, vlink, alink, etc.
2) Understand that width is a CSS property, not an HTML body attribute.
3) Remember that deprecated HTML attributes (like bgcolor) are still technically valid in older HTML, even though CSS is now preferred.
Q6. Select the correct option to fill in the blank : [1 mark]
A ________ is an online platform or website where individuals or businesses regularly publish articles/journals, known as posts, on various topics.
(A) Browser
(B) Blog
(C) News Group
(D) Web Server
Answer: (B) Blog
A blog is an online platform or website where individuals or businesses regularly publish articles or journals, known as posts, on various topics. Blogs allow content creators to share information, opinions, and experiences with a wide audience, and typically include features like comments and archives. A browser is a tool to view websites, a news group is a discussion forum, and a web server is a computer that hosts websites—none of these match the definition provided.
Teacher's Note:
1) Understand the key characteristics of a blog: regular posts, articles/journals, and online platform.
2) Distinguish between related terms: browser (viewing tool), web server (hosting), news group (discussion forum), and blog (publishing platform).
3) Remember that blogs are primarily content-sharing platforms with chronological posting of articles.
Q7. The default value for the type attribute of an Unordered List in HTML is : [1 mark]
(A) circle
(B) disc
(C) square
(D) triangle
Answer: (B) disc
In HTML, the default bullet style for an unordered list (<ul>) is disc, which displays as a filled circular bullet point. Other options like circle (hollow circle) and square (square bullet) can be specified using the type attribute, but when no type is specified, browsers render unordered lists with disc bullets by default.
Teacher's Note:
1) Remember the three main bullet types for unordered lists: disc (filled circle), circle (hollow circle), and square.
2) Know that disc is the default—no attribute needed to get it.
3) The type attribute can be used on <ul> or individual <li> tags to change the bullet style.
Q8. Which of the following is not a Search Engine available over the Internet ? [1 mark]
(A) Google
(B) Bing
(C) Diksha
(D) Yahoo
Answer: (C) Diksha
Google, Bing, and Yahoo are all well-known search engines available on the Internet that help users find and retrieve information from websites. Diksha, on the other hand, is a digital learning platform developed by the Government of India for educational content delivery and online learning—it is not a search engine. Therefore, Diksha is the correct answer as it is not a search engine available over the Internet.
Teacher's Note:
1) Distinguish between search engines (Google, Bing, Yahoo) and educational/digital platforms (Diksha).
2) Know that Diksha is India's official digital learning platform for education, not a search tool.
3) Recall the main function of a search engine: to index and retrieve web pages based on search queries.
Q9. Which of the following options is a network protocol that enables secure and encrypted file transfers between a client and a server ? [1 mark]
(A) SFTP
(B) Telnet
(C) SCP
(D) HTTP
Answer: (A) SFTP
SFTP (SSH File Transfer Protocol) is a network protocol that enables secure and encrypted file transfers between a client and a server. It uses SSH (Secure Shell) to provide encryption and authentication, ensuring that files are transferred safely over the network. Telnet is an unencrypted protocol, SCP is primarily for copying files but uses SSH for security, and HTTP is used for web content delivery without file transfer focus.
Teacher's Note:
1) SFTP combines FTP functionality with SSH encryption for secure file transfer.
2) Telnet and HTTP are unencrypted; SCP is less commonly used for general file transfer than SFTP.
3) Key term: 'encrypted file transfers' — this directly points to SFTP among the options.
Q10. Which of the following options will set the font family of all paragraphs to 'Arial' ? [1 mark]
(A) <style> p { font-family: Arial; } </style>
(B) <style> p { fontfamily: Arial; } </style>
(C) <style> p { font: Arial; } </style>
(D) <style> p { font-type: Arial; } </style>
Answer: (A) <style> p { font-family: Arial; } </style>
The correct CSS property to set the font family of HTML elements is font-family. Option (A) uses the correct syntax with the hyphenated property name font-family and applies it to all paragraph elements. Option (B) uses an incorrect property name fontfamily without the hyphen, option (C) uses font which is a shorthand for multiple font properties, and option (D) uses the non-existent property font-type.
Teacher's Note:
1) CSS property names are case-sensitive and use hyphens (e.g., font-family, not fontfamily).
2) The font shorthand property is for multiple properties; use font-family specifically for font type.
3) Common mistake: forgetting the hyphen in compound CSS property names.
Q11. Assertion (A) : FTP is a networking protocol used for transferring files. [1 mark]
Reason (R) : FTP is used when we want to view some data from a website.
Select the most suitable option considering the Assertion and Reason.
(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: (C) Assertion (A) is true, but Reason (R) is false.
The Assertion is correct: FTP (File Transfer Protocol) is indeed a networking protocol specifically designed for transferring files between a client and a server. However, the Reason is incorrect: FTP is not used for viewing data from a website. Viewing data from a website is done using HTTP (Hypertext Transfer Protocol). FTP is used for uploading and downloading files to and from servers, not for browsing web content. Therefore, while the Assertion accurately describes FTP's function, the Reason provides a false explanation of when FTP is used.
Teacher's Note:
1) FTP is for file transfer operations (upload/download), while HTTP is for viewing website content.
2) Reason (R) confuses FTP with HTTP — this is the key to identifying the correct answer.
3) In assertion-reason questions, both statements must be true AND logically connected for option (A) to be correct.
Q12. Assertion (A) : SMS is an acronym for Smart Message Service. [1 mark]
Reason (R) : SMS is the most common technology for delivering short, concise and important messages quickly.
Select the most suitable option considering the Assertion and Reason.
(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.
The Assertion is incorrect: SMS is an acronym for 'Short Message Service', not 'Smart Message Service'. The Reason is correct: SMS is indeed the most common technology for delivering short, concise, and important messages quickly, especially for urgent communications, notifications, and alerts. Since the Assertion provides an inaccurate expansion of the SMS acronym while the Reason accurately describes SMS's actual use and purpose, the answer is that Assertion (A) is false, but Reason (R) is true.
Teacher's Note:
1) SMS stands for 'Short Message Service' — the word 'Short' refers to message length, not 'Smart'.
2) Reason (R) is factually correct about SMS being widely used for quick message delivery.
3) Pay close attention to acronym expansions in assertion-based questions — this is a common source of errors.
SECTION B
Q13. What is a Digital Property ? Write any two examples of digital property. [2 marks]
Answer:
Digital Property: Digital property is data or assets belonging to an individual or an organization, which is in digital form. Alternatively, it can be defined as an intellectual property (IP) that exists in digital form, or any digital asset or online resource that an individual or entity owns or controls.
Examples of Digital Property (any two):
1) Text content on a website or system
2) Images stored digitally or displayed online
3) Audio content such as music or podcasts
4) Video content on platforms or stored on a device
Teacher's Note:
1) Define digital property clearly as data/assets in digital form or digital IP — do not confuse with physical property.
2) Provide two distinct examples; text, image, audio, and video are the standard curriculum examples.
3) Allocate 1 mark to definition and 0.5 marks each for two correct examples.
Q14(a). What is e-Shopping ? Write names of any two commonly used e-Shopping portals. [2 marks]
Answer:
e-Shopping: e-Shopping is the process of sale and purchase of products and services in an online mode. It enables customers to browse, select, and buy goods or services through internet-based platforms without visiting physical stores.
Names of two commonly used e-Shopping portals:
1) Amazon
2) Flipkart
3) BigBasket
4) Myntra
5) eBay
6) Blinkit
7) Swiggy
8) Zomato
(Any two from the list above are acceptable answers.)
Teacher's Note:
1) Define e-shopping as online buying and selling of products/services — emphasize the digital/online aspect.
2) List major portals such as Amazon, Flipkart, BigBasket, Myntra, and food delivery apps like Swiggy and Zomato; accept any commonly known portal.
3) Allocate 1 mark for correct definition and 0.5 marks each for two valid portal names.
Q14(b). What is a Social Network ? Write names of any two popular social networking sites on the Internet. [2 marks]
Answer:
Social Network: A social network is an online platform where people connect, share information, and interact with each other. These platforms allow users to create profiles, communicate, exchange messages, share content, and build communities based on shared interests.
Names of two popular social networking sites:
1) Facebook
2) Instagram
3) LinkedIn
4) X (formerly Twitter)
(Any two from the list above are acceptable answers. Other commonly used social networking sites are also acceptable.)
Teacher's Note:
1) Define social network as an online platform for connecting, sharing, and interaction — focus on the community and communication aspect.
2) Major examples include Facebook, Instagram, LinkedIn, and X; also accept WhatsApp, Snapchat, YouTube, and other popular platforms.
3) Allocate 1 mark for correct explanation and 0.5 marks each for two valid social networking site names.
Q15. State whether the following statements are True or False : [2 marks]
i) <h1> is the highest level of heading and <h4> is the lowest level of heading in HTML.
ii) A visited link is purple coloured by default in HTML.
iii) The character '#' is used to start a comment text in HTML.
iv) <b> is an empty tag in HTML as it does not need to be closed.
Answer:
True/False Statements in HTML:
i) False — <h1> is the highest level of heading, but <h6> (not <h4>) is the lowest level of heading in HTML. HTML supports six levels of headings: <h1> through <h6>.
ii) True — A visited link is purple coloured by default in HTML.
iii) False — The character '#' is not used to start comment text in HTML. Comments in HTML are written using <!-- comment text --> syntax.
iv) False — <b> is not an empty tag; it is a paired tag that requires both opening (<b>) and closing (</b>) tags to mark text as bold.
Teacher's Note:
1) Remember HTML heading levels: <h1> to <h6>, where <h1> is largest and <h6> is smallest.
2) Know default link colors: unvisited links are blue, visited links are purple.
3) HTML comments use <!-- --> syntax, not '#'; '#' is used in other languages like Python and CSS.
4) Distinguish between empty/void tags (like <br>, <img>, <hr>) and paired tags (like <b>, <i>, <p>).
Q16(a). Write the HTML code to create a link to the web page having URL as : [2 marks]
www.festivals.com/india/diwali.html
The mentioned web page should get opened in a new window/tab on clicking the text, 'FESTIVALS'.
Answer:
The HTML code to create a hyperlink that opens the given URL in a new window/tab is:
<a href="www.festivals.com/india/diwali.html" target="_blank">FESTIVALS</a>
Explanation:
1) The <a> tag creates a hyperlink.
2) The href attribute specifies the URL of the web page to be linked.
3) The target="_blank" attribute ensures that the link opens in a new window or tab instead of the current one.
4) The text 'FESTIVALS' is the clickable link text displayed on the web page.
Alternative method:
<a href="#" onclick="window.open('www.festivals.com/india/diwali.html', '_blank')">FESTIVALS</a>Teacher's Note:
1) Always use target="_blank" to open links in a new window/tab — it's the simplest and most standard method.
2) Check that the complete URL is correctly written in the href attribute.
3) The anchor tag must be properly closed with </a>.
4) The link text (between opening and closing tags) should match exactly what the question specifies.
Q16(b). (i) Write HTML code to display the following line of text in bold and italics. [2 marks]
Happiness is not by chance, but by choice.
(ii) Write the HTML code to set the background color of the web page as blue.
Answer:
(i) HTML code to display text in bold and italics:
<b><i>Happiness is not by chance, but by choice.</i></b>
OR
<strong><em>Happiness is not by chance, but by choice.</em></strong>
Explanation: The <b> tag (or <strong>) makes text bold, and the <i> tag (or <em>) makes text italic. Both tags must be used together to achieve both effects.
(ii) HTML code to set the background color of the web page as blue:
<body bgcolor="blue">
OR
<body style="background-color:blue;">
OR
<style>
body { background-color:blue; }
</style>Explanation:
1) The first method uses the bgcolor attribute within the <body> tag (older method).
2) The second method uses inline CSS with the style attribute.
3) The third method uses an internal stylesheet within the <style> tag in the <head> section (modern method).
Teacher's Note:
1) For part (i), ensure both bold and italic tags are present—missing either one will lose marks.
2) Both <b><i> and <strong><em> are equally acceptable; use whichever you're comfortable with.
3) For part (ii), any of the three methods is correct; the modern CSS method in <style> tag is preferred by most examiners.
4) Be careful with spelling: 'bgcolor' (one word) and 'background-color' (hyphenated) are both correct in their respective contexts.
Q17. Write the purpose of the following HTML tags : [2 marks]
i) <BR>
ii) <DL>
Answer:
(i) <BR> tag:
The <BR> tag is used to insert a line break in the HTML document. It forces the text or content that follows it to appear on a new line without creating a paragraph break. It is an empty tag that does not require a closing tag.
(ii) <DL> tag:
The <DL> tag is used to define a description list in HTML. It is used to create a list of terms and their corresponding descriptions. The <DL> tag works in conjunction with the <DT> tag (for terms) and the <DD> tag (for descriptions).
Teacher's Note:
1) For <BR>, mention that it inserts a line break and is a self-closing/empty tag.
2) For <DL>, clearly state it defines a description list and explain its association with <DT> and <DD> tags.
3) One mark is awarded for each correct purpose, so both answers must be complete and accurate.
4) Avoid confusing <DL> with ordered (<OL>) or unordered (<UL>) lists.
Q18(a). An incomplete CSS code within <head> . . . </head> is given below. Complete this code by filling in the blanks as per the specifications that follow. [2 marks]
<head>
<style>
body {__________ : __________ ; } <!--line 1 -->
P {
__________ ; __________ ; <!--line 2 -->
__________ ; __________ ; <!--line 3 -->
}
__________ <!--line 4 -->
{
Color : Blue;
}
</style>
</head>i) Line 1 : Page background color should be Yellow.
ii) Line 2 : Color of the paragraph text should be Red.
iii) Line 3 : Font family of the paragraph text should be Arial.
iv) Line 4 : The second biggest heading should be Blue in color.
Answer:
The completed CSS code with the blanks filled in is:
<head>
<style>
body { background-color : yellow ; }
body {
color : red ;
font-family : arial ;
}
h2
{
Color : Blue;
}
</style>
</head>Explanations:
1) Line 1: background-color : yellow; — Sets the page background color to yellow. Alternatively, you can use #ffff00 or rgb(255, 255, 0) for the color value.
2) Line 2: color : red — Sets the paragraph text color to red. Alternatively, use #ff0000 or rgb(255, 0, 0).
3) Line 3: font-family : arial — Specifies the font family for paragraph text as Arial.
4) Line 4: h2 — The <h2> tag represents the second biggest heading element in HTML, which is styled with blue color in the provided CSS rule.
Teacher's Note:
1) For color values, remember that color names (yellow, red), hex codes (#ffff00, #ff0000), and RGB values rgb(255, 255, 0) are all acceptable.
2) Property names like background-color and font-family use hyphens and must be spelled correctly.
3) Heading tags in HTML are h1 (largest), h2 (second largest), h3, and so on—know this hierarchy to identify h2 correctly.
4) Each blank is worth ½ mark; ensure all four blanks are filled correctly to get full 2 marks.
Q18(b). The following HTML code is expected to create an ordered list for a web page. Complete this code by filling in the blanks as per the specifications that follow : [2 marks]
<html> <body __________ : yellow> <!-- line 1 --> <p> <font __________ = Helvetica> <!-- line 2 --> FESTIVALS OF INDIA </p> <__________ > <!-- line 3 --> <__________ >HOLI <__________ > <!-- line 4 --> <__________ >DIWALI <__________ > <!-- line 5 --> <__________ > <!-- line 6 -->
i) Line 1 : Background color of the web page should be Yellow.
ii) Line 2 : Font for the paragraph should be Helvetica.
iii) Line 3 and Line 6 : An ordered list should start and end.
iv) Line 4 and Line 5 : Listing of the ordered list items.
Answer:
Line 1: bgcolor or style = "background-color:
Line 2: face
Line 3: <ol>
Line 4: <li> HOLI </li>
Line 5: <li> DIWALI </li>
Line 6: </ol>
Complete code:
<html> <body bgcolor="yellow"> <!-- line 1 --> <p> <font face="Helvetica"> <!-- line 2 --> FESTIVALS OF INDIA </font> </p> <ol> <!-- line 3 --> <li>HOLI</li> <!-- line 4 --> <li>DIWALI</li> <!-- line 5 --> </ol> <!-- line 6 --> </body> </html>
Teacher's Note:
1) Line 1: Use either bgcolor attribute or CSS style property for background color—both are acceptable.
2) Line 2: The correct attribute for font family is face, not family or font-family in the deprecated <font> tag.
3) Lines 3, 4, 5, 6: Remember ordered list tags are <ol> and </ol>; each item must be wrapped in <li> and </li> tags.
4) ½ mark per blank—allocate carefully to each opening and closing tag or attribute.
Q19. Write any two differences between Web Server and Web Client. [2 marks]
Answer:
The following are two key differences between a Web Server and a Web Client:
Difference 1: Function and Role
A web server's primary function is to host and serve web content (web pages, images, scripts, stylesheets, etc.) to clients over the internet. In contrast, a web client, typically a web browser like Chrome or Firefox, is used by end users to request and view web content from servers.
Difference 2: Request and Response Processing
A web server listens for incoming requests from clients, processes those requests, and sends back appropriate responses containing the requested resources or status messages (such as error codes). A web client sends requests to web servers for specific resources, receives the response from the server, processes it by rendering the web pages, and provides an interactive interface for users to navigate and submit forms.
Examples: Common web servers include Apache, Nginx, and IIS, while common web clients include Google Chrome, Mozilla Firefox, and Safari.
Teacher's Note:
1) Structure your answer around functional differences: what each does (serve vs. request/display).
2) Explain the request-response cycle clearly to show how server and client interact differently.
3) You may include one example of each (e.g., Apache for server, Chrome for client) to strengthen your answer.
4) Aim for two clear, distinct differences rather than repetitive ones—examiner expects substantive contrast.
SECTION C
Q20. The following HTML statements are not written properly. Re-write the correct statements with underlined corrections. The desired purpose of each statement is mentioned under it. [3 marks]
i) <BODY image="background.jpg">
<!--Page background should display the image named background.jpg-->
ii) <FONT height=5>
<!--Font should be 5 in size-->
iii) <img src="img.jpg" text="An Image">
<!--Image source should be img.jpg and its alternate text should be "An Image"-->
Answer:
(i) Correct statement:
<BODY background="background.jpg">
Explanation: The correct attribute for displaying a background image in the BODY tag is background, not image.
(ii) Correct statement:
<FONT size="5">
Explanation: The correct attribute to set font size in the FONT tag is size, not height.
(iii) Correct statement:
<img src="img.jpg" alt="An Image">
Explanation: The correct attribute for alternate text in an IMG tag is alt, not text. The alt attribute provides alternative text that displays if the image cannot be loaded.
Teacher's Note:
1) Remember: BODY uses background attribute for images, not image.
2) FONT tag uses size attribute (not height)—size values are typically 1–7.
3) IMG tag uses alt attribute (not text) for accessibility and fallback text.
4) Underline or highlight each correction clearly—examiners award 1 mark per corrected attribute.
Q21(a). Give the full form of the following : [3 marks]
i) TCP/IP
ii) SSH
Answer:
(i) TCP/IP
TCP/IP stands for Transmission Control Protocol / Internet Protocol.
(ii) SSH
SSH stands for Secure Shell.
Teacher's Note:
1) TCP/IP is a two-part acronym: TCP = Transmission Control Protocol; IP = Internet Protocol—mark both parts clearly.
2) SSH is a protocol for secure remote access; remember "Shell" refers to command-line interface access.
3) ½ mark per word in the marking scheme—be precise with terminology (e.g., "Protocol" not "Protocols").
4) Write the full forms clearly; examiners look for accuracy in each component word.
Q21(b). Consider the given URL : [3 marks]
Is it a secure website ? Justify your answer.
Answer:
No, it is not a secure website.
Justification: The given URL uses the HTTP (HyperText Transfer Protocol) protocol, which is not secure. A secure website must use the HTTPS (HyperText Transfer Protocol Secure) protocol instead. HTTPS encrypts the data transmitted between the client and server, protecting sensitive information like passwords, personal details, and payment information from being intercepted by unauthorized users. Since the URL http://www.mypage.com/ uses HTTP instead of HTTPS, it is not a secure website.
Teacher's Note:
1) Always identify the protocol in the URL (http vs https) — this is the key differentiator.
2) Explain that HTTPS provides encryption and security while HTTP does not.
3) Mention protection of sensitive data (passwords, payment info) to justify why HTTPS is needed.
Q22(a). Explain how to insert an audio on a web page using <audio> tag. Give example to support your answer. [3 marks]
Answer:
The <audio> tag is used to embed audio files in a web page. It allows you to add sound content that can be played directly in the browser. The tag supports various audio formats and provides built-in controls for users to play, pause, and adjust volume.
Example:
<audio controls> <source src="songs.mp3"> </audio>
In this example, the controls attribute displays the audio player controls (play, pause, volume) in the browser. The <source> tag specifies the audio file to be played. The src attribute points to the audio file "songs.mp3". When a browser encounters this code, it will display an audio player on the web page that allows users to play the audio file.
Teacher's Note:
1) Always include both the opening and closing <audio> tags with the controls attribute.
2) Use the <source> tag with the src attribute to specify the audio file path.
3) A complete example with proper syntax is essential — explanation alone without code will lose marks.
Q22(b). Akhil, an entrepreneur, has made some videos for marketing purposes. He wants to create a web page and share these videos to increase his customers on the online platform. Help Akhil to do the same with the given instructions : [3 marks]
i) Use HTML to put a video "products.mp4" in the web page.
ii) The video should autoplay in the width of 400 pixels and height 300 pixels in the browser window.
iii) The video controls buttons – Play, Pause and Volume should be visible.
Answer:
To help Akhil create a web page to display and share his marketing videos, here is the HTML code:
<video width="400" height="300" controls autoplay> <source src="products.mp4"> </video>
Explanation of the code:
1) <video> tag: This tag is used to embed the video file in the web page.
2) width="400": Sets the width of the video player to 400 pixels.
3) height="300": Sets the height of the video player to 300 pixels.
4) controls: This attribute displays the video control buttons including Play, Pause, and Volume controls so users can interact with the video.
5) autoplay: This attribute makes the video start playing automatically when the page loads (optional but mentioned in the instructions).
6) <source src="products.mp4">: The source tag specifies the path to the video file "products.mp4" that needs to be displayed.
When this HTML code is added to Akhil's web page, the video will be displayed in a 400×300 pixel area with all the necessary controls visible, allowing his customers to easily view and interact with the marketing videos.
Teacher's Note:
1) Include all attributes in the <video> tag: width, height, controls, and autoplay.
2) Properly nest the <source> tag inside the <video> tag with the correct src attribute.
3) Examiners award marks for each component, so ensure proper syntax and all required attributes are present.
Q23(a). Write suitable HTML statements to display the following text on a web page : [2 marks]
i) Ca (OH)₂
ii) 2 (A² + B²)
Answer:
(i) Ca (OH)₂
HTML Statement:
Ca (OH) <sub>2</sub>
The <sub> tag is used to display the subscript text. The "2" in this chemical formula needs to be written as a subscript to correctly represent Calcium Hydroxide.
(ii) 2 (A² + B²)
HTML Statement:
2 (A<sup>2</sup> + B<sup>2</sup>)
The <sup> tag is used to display the superscript text. Both the exponents "2" in A² and B² need to be written as superscripts to correctly represent the mathematical expression.
Teacher's Note:
1) Use <sub> for subscripts (like in chemical formulas) and <sup> for superscripts (like in mathematical expressions).
2) Remember to close both tags properly with the matching closing tag.
3) One mark is awarded for each correct statement, so accuracy in both syntax and tag selection is essential.
Q23(b). Give any one advantage of CSS. [1 mark]
Answer:
One advantage of CSS is that it makes it easy to manage and design a website. By using CSS, web developers can control the visual presentation of web pages efficiently, apply consistent styling across multiple pages, and make updates to the design without modifying the HTML content itself. This separation of style from content allows for faster development and easier maintenance of websites.
Teacher's Note:
1) Accept any one valid advantage from the marking scheme or any other legitimate benefit of CSS.
2) Key advantages to know: separation of content and design, easier maintenance, reusability, consistency across pages.
3) One sentence is sufficient for 1 mark; avoid over-elaboration.
4) Common mistake: confusing CSS advantages with HTML purposes.
SECTION D
Q24(a). Write the HTML code to design the web page as shown below : [4 marks]
Student Data Entry Form
Name : [____]
Gender : ○ Male ○ Female ○ Other
Languages : ☐ English ☐ Hindi
Stream: [Science ▼]
[Science]
[Commerce]
[Humanities]
[Submit]
Note:
1) The title of the page should be 'Student Data Entry Form'.
2) The heading 'Student Data Entry Form' on the web page should be of largest possible size.
Answer:
<html> <head> <title>Student Data Entry Form</title> </head> <body> <h1><b>Student Data Entry Form</b></h1> <form> Name: <input type="text"> <br> Gender: <input type="radio" name="gender" value="Male"> Male <input type="radio" name="gender" value="Female"> Female <input type="radio" name="gender" value="Other"> Other <br> Languages: <input type="checkbox" value="English"> English <input type="checkbox" value="Hindi"> Hindi <br> Stream: <select name="stream"> <option value="Science">Science</option> <option value="Commerce">Commerce</option> <option value="Humanities">Humanities</option> </select> <br> <input type="submit"> </form> </body> </html>
Teacher's Note:
1) Use <h1> tag for the largest heading size; ensure title matches the requirement exactly.
2) Radio buttons must have the same 'name' attribute to ensure only one can be selected at a time.
3) Checkboxes allow multiple selections, so they don't share the same name attribute.
4) Always close form, input, and select tags properly; use <br> for line breaks between form elements.
Q24(b). Write the HTML code to design the web page as shown below (Table border should be 1, height=150 and width=350 with cellpadding=15): [4 marks]
| JANUARY 2025 | |
| NAME | ATTENDANCE |
| Abha | Present |
| Alok | Absent |
| Teacher: Ms. Anju | |
Answer:
<html> <body> <table border=1 height=150 width=350 cellpadding=15> <tr> <td colspan=2><center>JANUARY 2025</center></td> </tr> <tr> <td><b>NAME</b></td> <td><b>ATTENDANCE</b></td> </tr> <tr> <td>Abha</td> <td>Present</td> </tr> <tr> <td>Alok</td> <td>Absent</td> </tr> <tr> <td colspan=2>Teacher: Ms. Anju</td> </tr> </table> </body> </html>
Teacher's Note:
1) Include all table attributes: border=1, height=150, width=350, cellpadding=15 in the <table> opening tag.
2) Use colspan=2 for the first and last rows to span across both columns; the first row should be centered.
3) Header row (NAME and ATTENDANCE) should use <b> tag or <th> tag to emphasize column titles.
4) Common mistake: forgetting cellpadding attribute or incorrect colspan values; always verify row structure matches the image.
SECTION E
Q25(i). What is the name of the act that Sujata has committed by copying contents from Internet to her projects? [1 mark]
Answer:
The act that Sujata has committed by copying contents from the Internet to her projects is called Plagiarism. This refers to the unauthorized use or reproduction of someone else's work, ideas, or creative content without proper attribution or permission. Plagiarism is a serious ethical violation in academic and professional settings and can result in disciplinary action.
Teacher's Note:
1) Acceptable answers: Plagiarism, Copyright Infringement, or Piracy—all are valid.
2) Plagiarism specifically refers to copying without credit; copyright infringement refers to unauthorized use of copyrighted material.
3) For 1 mark, a simple one-word or one-phrase answer is sufficient; elaboration is optional.
4) Common mistake: confusing plagiarism with general dishonesty; be precise with terminology.
Q25(ii). The content available over the Internet which Sujata is copying could be another person's ____________ property. (Digital/Physical) [1 mark]
Answer:
The content available over the Internet which Sujata is copying could be another person's Digital property.
Teacher's Note:
1) Content on the Internet (text, images, videos, code) is classified as digital property, not physical property.
2) Digital property is protected under intellectual property laws and copyright regulations.
Q25(iii). To copy someone else's content from the Internet is not considered as good behaviour. What is the term used for good behaviour that should be followed on the Internet? [1 mark]
Answer:
The term used for good behaviour that should be followed on the Internet is Netiquette (also known as Cyber Ethics or Internet Etiquette).

3) Key concept: It is the social code of conduct for online interactions and digital resource sharing.
Q25(iv). Sujata is violating IPR of the original content creator. Expand the term IPR. [1 mark]
Answer:
IPR stands for Intellectual Property Rights. Intellectual Property Rights are the legal rights granted to creators and owners of original works, including literary works, inventions, designs, music, videos, software code, and other creative content. These rights protect the creator's work from unauthorized copying, distribution, or modification without permission.
Teacher's Note:
1) IPR = Intellectual Property Rights — the complete expansion is essential.
2) IPR protects original creative works and gives creators the exclusive right to use, reproduce, and distribute their work.
3) Copying someone's content without permission violates their IPR and is illegal.
Q26(a). What is open source software? [1 mark]
Answer:
Open Source Software is software whose source code is freely available to anyone to use, modify, study, and distribute. Users are allowed to access the underlying source code, make improvements, and share the enhanced versions with others. This collaborative approach allows communities of developers to contribute to the software's development, fix bugs, add features, and improve it collectively. Examples include Linux, Apache, and Firefox. Open source software promotes transparency, innovation, and community-driven development while typically being free of cost.
Teacher's Note:
1) Key characteristics: free access to source code, modify and distribute freely, community collaboration.
2) Emphasize that open source is about transparency and collaborative improvement, not just being free.
3) Contrast with proprietary software where source code is hidden and users cannot modify or redistribute it.
Q26(b). Give any two examples of open source software. [1 mark]
Answer:
Any two examples of open source software are:
1) Linux
2) Python
3) Mozilla Firefox
4) LibreOffice
5) Apache OpenOffice
Note: Any two of the above examples are acceptable. (1 mark for each correct example)
Teacher's Note:
1) Open source software has freely available source code that users can modify and distribute.
2) Common CBSE examples include Linux, Python, Firefox, LibreOffice, and Apache OpenOffice.
3) Simply name any two — no need to explain features unless asked.
4) Avoid proprietary software like Windows or Microsoft Office.
Q26(c). Mention any two advantages of open source software. [1 mark]
Answer:
Any two advantages of open source software are:
1) Source code available: The source code of open source software is freely available to users, allowing them to view, understand, and modify the code according to their needs.
2) Cost effective: Open source software is typically free or very low-cost, making it economically efficient for individuals and organizations without significant budget constraints.
Note: Other valid advantages such as security, flexibility, community support, and no vendor lock-in are also acceptable.
Teacher's Note:
1) The marking scheme explicitly accepts source code availability and cost-effectiveness as the main answers.
2) Other valid advantages include enhanced security, greater flexibility, strong community support, and freedom from vendor dependence.
3) Structure your answer with clear point and brief explanation for each advantage.
4) Ensure you write at least two distinct advantages to secure full marks.
Q26(d). Define the term "Software License". [1 mark]
Answer:
Software License:
A software license is a legal agreement that specifies how software can be used, modified, and distributed. It outlines the terms and conditions under which users are allowed to operate the software. The license defines the rights and restrictions granted to the end user, such as whether the software can be copied, modified, sold, or distributed to others. Different types of licenses have different terms; for example, some may allow free use while others may require payment, and some may permit modifications while others restrict them.
Teacher's Note:
1) A software license is fundamentally a legal contract between the software creator and the user.
2) Key elements: it specifies rights granted, restrictions on use, modification, and distribution terms.
3) Definition should cover: legality, usage terms, conditions, and user rights/restrictions.
4) Mention that different licenses have different restrictions (proprietary vs. open source).
