Web Technologies (RIT-601)

Complete Section-Wise Explanation – B.Tech Semester VI

Introduction to the Subject

Web Technologies is a core subject that explains how modern websites and web applications are designed, developed, and executed. It connects frontend technologies like HTML, CSS, JavaScript, and XML with backend technologies such as Java Servlets, JSP, Java Beans, sessions, and databases.

This paper mainly tests:

Conceptual clarity of web fundamentals Understanding of client–server architecture

Practical knowledge of HTML, CSS, XML, JavaScript Server-side programming using JSP & Servlets

Session management and database connectivity

The paper is divided into three sections: A, B, and C, each focusing on a different depth of understanding.

SECTION A – Basic Concepts & Definitions

Pattern:
Attempt all questions
7 questions × 2 marks = 14 marks

Nature of Section A

Section A checks your foundation knowledge. Questions are short, but answers must be accurate. This section is scoring if you clearly know definitions and differences.

Explanation of Section A Topics

Difference Between Portal and Website
A website usually provides information related to a single topic or organization, while a portal integrates information from multiple sources and often requires user authentication, such as student or employee portals.

Packages and Interfaces as Containers
In Java, packages group related classes and interfaces, helping in modularity and access control. Interfaces act as containers for abstract methods, ensuring standardization and loose coupling.

XML vs HTML
HTML is used for displaying data and focuses on presentation, whereas XML is used for storing and transporting data with user-defined tags.

Difference Between <div> and <span>
<div> is a block-level element used for layout, while <span> is an inline element mainly used for styling small parts of text.

Submitting Data on the Same Page
This can be done using self-submitting forms where the action attribute points to the same page.

Role of CGI in Web Design
CGI (Common Gateway Interface) allows a web server to execute external programs to generate dynamic content.

SendRequest() vs Hyperlink
sendRequest() is used in asynchronous communication (like AJAX), while a hyperlink causes a full page reload and synchronous request.

SECTION B – Descriptive & Application-Based Questions

Pattern:
Attempt any three questions
3 × 7 marks = 21 marks

Nature of Section B

This section tests your ability to explain concepts properly with examples. Answers should be written in paragraphs with logical flow.

Explanation of Important Questions

Early Planning in Website Development

Early planning helps define objectives, target audience, structure, and content. It reduces rework, saves time, and ensures user-friendly design. For example, an e-commerce site needs different planning than an educational website.

Role and Importance of CSS

CSS controls layout, colors, fonts, and responsiveness of a website. It separates content from presentation, improves maintainability, and ensures consistency.
Class selectors can be reused multiple times, while ID selectors are unique and used for specific elements.

Session Beans

Session Beans are Java components used in server-side programming to handle business logic.
Stateless session beans do not retain client information, while stateful session beans maintain client-specific data across requests.

Request Dispatcher

Request Dispatcher allows one resource to forward or include another resource in response processing. Objects can be obtained using request.getRequestDispatcher() or ServletContext.getRequestDispatcher().

Role of JavaScript in Web Pages

JavaScript adds interactivity, validation, and dynamic behavior to web pages.
A simple function can check whether a textbox is empty before form submission.

SECTION C – Long Answer & Advanced Concepts

Pattern:
Attempt one part from each question
5 questions × 7 marks = 35 marks

This section carries the maximum weightage and requires structured, detailed answers.

Question 3 – Web Project & JSP

Objective of a Website & Team Skills

The objective of a website may include information sharing, business promotion, service delivery, or user interaction.
A web project team needs skills in design, programming, database management, testing, and project coordination.

JSP Include Directive vs Action

Include directive (<%@ include %>) is processed at translation time, while include action (<jsp:include>) is processed at runtime.

Question 4 – Java Beans & Database Connectivity

Java Bean

A Java Bean is a reusable Java component following specific conventions. Steps include creating a class, private variables, public getters/setters, and serialization.
Introspection allows tools to analyze bean properties automatically.

Database Drivers

JDBC drivers are classified into four types. Data insertion involves loading driver, establishing connection, creating statement, executing query, and closing connection.

Question 5 – XML & HTML Frames

Importance of DTD in XML

DTD defines structure, elements, and rules of an XML document, ensuring validity. Internal DTD is used for small documents, while external DTD is preferred for reuse.

Frameset in HTML

Frameset divides the browser window into multiple sections, each loading a different HTML file like header, menu, and output.

Question 6 – JSP & Servlets

JSP vs Servlets

JSP is an extension of servlets, not a replacement. JSP simplifies presentation logic and reduces complexity of servlet-based HTML generation.

Servlet Deployment on Tomcat

Deployment involves creating a web application directory, placing servlet classes, configuring web.xml, and starting the server.
Changing the default port requires editing server.xml.

Question 7 – Sessions & Networking

Session Handling in HTML with JavaScript

HTML alone cannot manage sessions. JavaScript can store temporary data using cookies or local storage, but true session management is handled server-side.
