CBSE Class 12 Informatics Practices Web Application Development Assignment

Brief Summary of the Chapter:
World Wide Web is an example of an information protocol/service that can be used to send
and receive information over the internet. It supports:
• Multimedia Information (Text, Movies, Pictures, Sound, Programs etc…)
• Hyper Text Information : ( Information that contains links to other information resources)
• Graphical User Interface :(So users can point and click to request information instead of typing in text commands)
The World Wide Web is an example of an information protocol/service that works using a
Client/Server software design. A service that uses Client/Server design requires two pieces of software to work: Client software (e.g. Web Browser) to request information, and Server software(Web server) to answer requests and provide their information. Most Web applications are designed this way.

Key Points of the Chapter:

Uniform Resource Locator: The uniform resource locator (URL) is the unique identifier of a web page. The address or URL of the current page you are on appears in the "Address Bar" of the web browser.

What is Web Server: Web server delivers (serves) content, such as web pages, using the Hypertext Transfer Protocol (HTTP), over the World Wide Web.

What is Web Browser: A web browser is a client that initiates communication by making a request for a specific resource. The server then responds with the content of that resource, or an error message if unable to do provide the contents due to any reason.

Client Server Computing: It refers to a network set-up in which programs and information reside on the server and clients connect to the server for network access.

Dynamic Web Page: A dynamic document is created by web server whenever a browser requests the documents.

Static Web Page: A static document is a fixed content document that is created by web server
whenever a browser requests the documents.
