Web Pages and Technologies


Web Pages and Technologies

I. Introduction

Web Pages and Technologies play a crucial role in E-Commerce and Web Technology. In this topic, we will explore the fundamentals of web pages and technologies, their importance in the field, and various concepts associated with them.

II. Static and Dynamic Web Pages

Static web pages are fixed and do not change unless manually updated, while dynamic web pages are generated on the fly and can change based on user interactions or data. Some advantages of static web pages include faster loading times and simplicity, while dynamic web pages offer interactivity and real-time updates. Real-world examples of static web pages include informational websites, while dynamic web pages can be seen in social media platforms or e-commerce websites.

III. Tiers, Plug-ins, Frames, and Forms

Web development involves multiple tiers, including the presentation tier, application tier, and data tier. Each tier has its own role and responsibilities in the development process. Plug-ins are additional software components that enhance the functionality of web browsers. Frames are used to divide a web page into multiple sections, allowing for independent scrolling and content loading. Forms are an essential part of web pages, allowing users to input data and interact with the website.

IV. Markup Languages

Markup languages are used to structure and present content on the web. HTML (Hypertext Markup Language) is the most widely used markup language, responsible for defining the structure of web pages. DHTML (Dynamic HTML) combines HTML, CSS, and JavaScript to create interactive web pages. VRML (Virtual Reality Modeling Language) is used for creating 3D graphics on the web. SGML (Standard Generalized Markup Language) is a standard for defining markup languages, while XML (eXtensible Markup Language) is a versatile markup language used for data storage and exchange.

V. CGI, Applets & Serve-lets

CGI (Common Gateway Interface) is a standard protocol that allows web servers to interact with external programs. Applets are small programs written in Java that can be embedded in web pages to provide additional functionality. Serve-lets are Java programs that run on a web server and generate dynamic content. They are commonly used in conjunction with JSP (JavaServer Pages).

VI. JSP & JAVA Beans

JSP (JavaServer Pages) is a technology that allows the creation of dynamic web pages using Java. It combines HTML and XML-like tags with Java code to generate dynamic content. JAVA Beans are reusable components that encapsulate data and behavior, making them ideal for use in JSP. They allow for modular and maintainable web development.

VII. Active X Control

Active X Control is a technology developed by Microsoft that allows for interactive and rich media content on web pages. It provides functionality beyond what HTML and JavaScript can offer, but it is limited to Windows-based systems and has security concerns. Active X Control is commonly used for multimedia playback, document viewing, and other interactive features.

VIII. ASP Cookies

Cookies are small pieces of data stored on the user's computer by websites. They are commonly used for session management, personalization, and tracking user behavior. ASP (Active Server Pages) is a server-side scripting language that allows for the creation and manipulation of cookies. This section will provide a step-by-step guide on creating and reading cookies in ASP and showcase real-world examples of their usage.

IX. Semantic Web

The semantic web is an extension of the World Wide Web that aims to make web content more meaningful and understandable to computers. It involves the use of semantic technologies, such as ontologies, to structure and link data. Semantic web service ontology provides a standardized way of describing web services, enabling interoperability and automation. Real-world applications of the semantic web include intelligent search engines, recommendation systems, and data integration.

X. Conclusion

In conclusion, understanding web pages and technologies is essential in the field of E-Commerce and Web Technology. We have covered various concepts and principles, including static and dynamic web pages, tiers, plug-ins, frames, and forms, markup languages, CGI, applets and serve-lets, JSP and JAVA Beans, Active X Control, ASP cookies, and the semantic web. By grasping these concepts, you will be well-equipped to develop and maintain modern web applications.

Summary

Web Pages and Technologies play a crucial role in E-Commerce and Web Technology. In this topic, we explore the fundamentals of web pages and technologies, including static and dynamic web pages, tiers, plug-ins, frames, and forms, markup languages, CGI, applets and serve-lets, JSP and JAVA Beans, Active X Control, ASP cookies, and the semantic web. Understanding these concepts is essential for developing and maintaining modern web applications.

Analogy

Imagine web pages as houses and technologies as the construction tools. Static web pages are like pre-built houses that remain the same unless manually modified, while dynamic web pages are like houses that can change their appearance based on user preferences or external factors. Tiers, plug-ins, frames, and forms are like different rooms and features within a house, each serving a specific purpose. Markup languages are like the blueprints that define the structure and design of the houses. CGI, applets, and serve-lets are like specialized tools used by construction workers to add functionality and interactivity to the houses. JSP and JAVA Beans are like architects and interior designers who create customized houses using a combination of predefined components. Active X Control is like a high-tech gadget that enhances the functionality and entertainment value of the houses. ASP cookies are like personal assistants who remember user preferences and provide a personalized experience. The semantic web is like a smart home system that understands and connects different devices and services, making the overall experience more intelligent and efficient.
