7. In the client-server model, what does the web client do?

A. It encrypts every data transmission between networks

B. It requests a service or resource from a web server

C. It stores web pages and transmits responses to browsers

D. It assigns domain names to server IP addresses

Answer: (B)

Explanation

A web client, typically browser software, requests web pages or files from a web server. The server fulfills the request and sends the response.

A. A browser such as Chrome or Firefox that uses HTTP to request pages

B. Server software such as Apache that receives requests and sends responses

C. DNS software that translates a domain name into a server IP address

D. An ISP application that provides a customer with network access

Answer: (A)

Explanation

A web client is browser software such as Internet Explorer, Chrome, or Firefox. It uses HTTP to request web pages and files from a web server.

9. What does a web server transmit after receiving a browser's request?

A. A status code, the requested web page, and associated files

B. A domain name, a browser installation, and an encrypted password

C. A URL, a DNS query, and the user's network connection

D. A packet-switching algorithm, an ISP account, and a TCP/IP address

Answer: (A)

Explanation

Web server software, such as Apache or Internet Information Server, receives requests and transmits a status code, web page, and associated files.

10. Which sequence accurately describes a typical web communication process?

A. The server enters a URL, the browser assigns an IP address, DNS sends an HTML request, and the user receives a TCP/IP response

B. The user enters a URL, DNS provides the server IP address, the browser sends an HTTP request, and the server returns HTML in an HTTP response

C. The browser opens a page locally, the server requests a URL from the user, and DNS transmits the home page without HTTP

D. The user enters a URL, the browser sends HTML to DNS, the server identifies the browser, and DNS returns an encrypted page

Answer: (B)

Explanation

Web communication begins with a URL entry, followed by DNS resolution, an HTTP request from the browser, and an HTTP response from the server containing the home page as HTML.

11. Which technology defines the structure and content of a basic web page?

A. CSS

B. TCP/IP

C. HTML

D. JavaScript

Answer: (C)

Explanation

HTML creates basic web pages and defines their structure and content. CSS styles that content, while JavaScript adds interactivity.

12. A developer wants to change the colors, fonts, and layout of a web page without changing its content structure. Which technology is most appropriate?

A. CSS

B. JavaScript

C. HTML

D. TCP/IP

Answer: (A)

Explanation

CSS is used to style web pages, including their colors, fonts, and layout. HTML defines structure, whereas JavaScript provides interactivity.

13. What do TCP/IP protocols define on the Internet?

A. How web pages are visually styled

B. How data should travel between networked systems

C. How users create interactive animations

D. How website content is organized

Answer: (B)

Explanation

TCP/IP consists of communication protocols that define how data should travel across the Internet. It does not determine page styling, structure, or interactive features.

14. Which description best characterizes Web 1.0?

A. A transactional web where users perform business functions

B. A semantic web where artificial intelligence personalizes content

C. A social, read-write web where users create and share content

D. A static, read-only web where users mainly consume information

Answer: (D)

Explanation

Web 1.0 is a read-only, static web in which users passively consume information by listening, reading, and watching. User-generated social content is characteristic of Web 2.0.

15. A platform allows users to write articles, edit shared pages, and publish posts for others to respond to. Which stage of web evolution does this best represent?

A. Web 3.0

B. Web 1.0

C. Web 2.0

D. The static web

Answer: (C)

Explanation

Web 2.0 is a social, read-write web in which users create content and act as producer-consumers. Web 1.0 users primarily consumed information passively.

16. Which feature most clearly distinguishes Web 3.0 from earlier stages of the web?

A. Users publish content on social platforms

B. Web pages are manually updated in HTML

C. Users passively read static pages

D. Computers analyze data and tailor content to users' needs

Answer: (D)

Explanation

Web 3.0, or the Semantic Web, is described as read-write-execute and uses artificial intelligence and machine learning to analyze data and generate and distribute suitable content.

17. A website displays fixed informational pages that administrators revise manually in HTML. How should this website be classified?

A. A static website

B. A web application

C. A rich Internet application

D. A dynamic website

Answer: (A)

Explanation

A static website has content that does not change automatically or frequently, is updated manually, and is written in HTML. Database-generated updates characterize dynamic websites.

A. A dynamic website

B. A static website

C. A file-sharing service

D. A discussion forum

A. A blog containing manually published articles

B. A page describing a company's history

C. An online portal where users register for courses and complete transactions

D. A site displaying a fixed list of office locations

Answer: (C)

Explanation

A web application supports user interactions and transactions while performing actual business functions, such as HCT portal registration. Informational pages and blogs primarily present content.

20. What does responsive design enable a website to do?

A. Use a separate site for every browser

B. Adapt one site to different screen sizes

C. Replace HTML with image-based pages

D. Display identical layouts on every device

Answer: (B)

Explanation

Responsive design creates one website that responds and adapts to various screen sizes. Separate layouts may be needed when a page is not responsive.

21. Why might a very small browser require a completely different webpage layout?

A. Because hosting servers prevent responsive design

B. Because monitor size and screen resolution affect display

C. Because FTP software changes the HTML structure

D. Because domain names determine page formatting

Answer: (B)

Explanation

The way a page is displayed depends on monitor size and screen resolution, and very small browsers may require a different layout.

22. What does browser compatibility mean in website design?

A. A browser can properly interpret HTML

B. A website adjusts to every screen size

C. A server provides space for website files

D. A domain name identifies a website

Answer: (A)

Explanation

Browser compatibility is the ability of a web browser to properly interpret HTML. Adapting to screen sizes is a feature of responsive design, not browser compatibility.

23. Which sequence correctly describes the main steps for publishing a website?

A. Rent a server, test screen sizes, and replace the HTML

B. Choose a browser, write HTML, and adjust monitor resolution

C. Upload files using FTP, create a domain, and design a logo

D. Register a domain, choose hosting, and upload files using FTP

Answer: (D)

Explanation

Website publishing involves registering a domain name, selecting a hosting option, and uploading the site to the hosting server using FTP software.

24. What is the key difference between hosting a website on the owner's server and using rented hosting space?

A. The first uses the owner's server, while the second uses leased server space

B. The first requires HTML, while the second requires CSS

C. The first supports browsers, while the second supports screen readers

D. The first uses FTP, while the second uses a domain name

Answer: (A)

Explanation

A website can be hosted on the owner's server or in rented hosting space. The distinction concerns who provides and controls the server space, not the technologies used to build the site.
