B.Tech 3rd Year AKTU Web Technology PYQs – Exam Guide – Download BCS503 PYQ PDF

-

Web Technology is a critical subject for AKTU 3rd Year B.Tech students, combining theory, protocols, and programming skills to design and develop websites and web applications. This tutorial covers client-side and server-side technologies, essential protocols, HTML, CSS, JavaScript, and previous year question trends to help students prepare effectively for exams.

Introduction to Web Technology

Web Technology involves using programming languages, tools, and protocols to build, maintain, and optimize web systems. It integrates front-end and back-end development to deliver interactive websites and applications. With web technology, students learn to create dynamic web pages, manage databases, and implement server-side logic efficiently.

The importance of Web Technology includes enabling online business, facilitating remote education, supporting e-commerce, improving information accessibility, and connecting global users. It also forms the foundation for emerging technologies like cloud computing, AI integration in web apps, and progressive web applications (PWAs).

Why Previous Year Questions (PYQs) Matter

  • High Repeatability: Many short and long questions are repeated across years.
  • Unit-wise Patterns: Each topic contributes consistently to exams.
  • Scoring Potential: Basics of HTML, CSS, JavaScript, and protocols are easy marks.
  • Smart Revision: Focus on high-weight topics improves preparation efficiency.
  • Time Management: Prioritize PYQ-oriented content for maximum exam coverage.

Core Components of Web Technology

1. Client-Side Technologies

Client-side technologies run in the user’s browser and control page layout, style, and interactivity. The core client-side tools include:

  • HTML: Defines the structure of web pages using tags and semantic elements.
  • CSS: Adds styling, colors, positioning, and layout control.
  • JavaScript: Provides interactivity, dynamic content, and event-driven programming.

2. Server-Side Technologies

Server-side technologies handle business logic, data processing, and database interactions. These include:

  • Web Servers: Apache, IIS
  • Scripting Languages: PHP, JSP, ASP.NET, Node.js
  • Databases: MySQL, Oracle, MongoDB
  • Frameworks: Django, Express.js, Laravel

3. Web Protocols

Protocols define communication rules between client and server:

  • HTTP: Stateless protocol for requesting and transferring web resources. Methods include GET, POST, PUT, DELETE.
  • HTTPS: Secure version of HTTP using SSL/TLS encryption for data protection.
  • FTP: Used for file transfer between client and server.
  • DNS: Converts domain names to IP addresses for routing requests.
  • SMTP/POP3: Protocols for sending and receiving emails.

Web Architecture Overview

Web architecture describes how web systems interact. A typical architecture includes:

  • Client: Browser interface handling display and input.
  • Server: Processes requests, executes business logic, and communicates with the database.
  • Database: Stores and retrieves persistent data.
  • Protocols: HTTP/HTTPS handle communication between client and server.

Quick Revision Notes

HTML Essentials

  • Semantic Tags: <header>, <footer>, <article>
  • Forms: <form>, <input>, <textarea>
  • Media: <img>, <video>, <audio>

CSS Essentials

  • Selectors: Element, class, ID
  • Box Model: margin, border, padding, content
  • Layout: Flexbox and Grid systems
  • Positioning: static, relative, absolute, fixed

JavaScript Essentials

  • Variables: var, let, const
  • Functions and Events
  • DOM Manipulation
  • AJAX for asynchronous updates
  • ES6 Features: arrow functions, template literals, promises

Formula / Syntax Zone

Basic HTML Structure:
<!DOCTYPE html>
<html>
  <head></head>
  <body></body>
</html>
CSS Syntax Example:
selector { property: value; }
JavaScript Function Example:
function greet() {
  alert("Hello, World!");
}

Real-World Applications

Web Technology powers platforms like Amazon, Flipkart, Netflix, government portals, and educational LMS platforms. E-commerce sites use HTML, CSS, and JS to provide responsive and interactive experiences. Server-side scripting ensures secure transactions and database management. Web protocols like HTTPS protect sensitive user information while AJAX allows dynamic page updates without full reloads.

Learning Web Technology also aids in understanding emerging areas such as Progressive Web Apps (PWAs), Single Page Applications (SPAs), and integrating AI/ML models into web interfaces. Skills in client-server communication, DOM manipulation, and responsive design are in high demand in the IT industry.

Career Opportunities

Mastery of Web Technology opens careers in:

  • Front-End Developer: Focused on UI/UX and interactive design.
  • Back-End Developer: Server-side programming and database management.
  • Full Stack Developer: Handles both front-end and back-end development.
  • Web Designer: Focuses on aesthetics and user experience.
  • Software Engineer: Works on web-based applications, cloud, or mobile integration.

10 Exam-Oriented Questions (PYQ Style)

1. What is the difference between HTTP and HTTPS?
A: HTTPS encrypts data using SSL/TLS, HTTP does not.

2. Explain client-side vs server-side scripting.
A: Client-side runs in the browser (HTML, CSS, JS), server-side runs on the server (PHP, JSP).

3. Name semantic HTML tags.
A: <header>, <footer>, <article>, <section>.

4. What is DNS?
A: Domain Name System translates domain names to IP addresses.

5. Explain the CSS Box Model.
A: Layout model with content, padding, border, and margin.

6. What is AJAX?
A: Asynchronous JS & XML for dynamic page updates without reload.

7. Describe three-tier web architecture.
A: Client (UI), Server (logic), Database (data).

8. Name common HTTP request methods.
A: GET, POST, PUT, DELETE.

9. How do JavaScript events work?
A: Events trigger functions in response to user actions like click, hover, or input.

10. Name popular server-side scripting languages.
A: PHP, JSP, ASP.NET, Node.js.

Conclusion

Web Technology is a high-priority subject for AKTU 3rd Year students. By mastering client-side and server-side tools, protocols, and PYQ patterns, students can achieve high marks and practical skills. Regular practice, understanding real-world applications, and focusing on core technologies will ensure exam success and career readiness in web development and IT industries.
