User:Elina Lesson Plan 9

Subject: Computer Science

Class: 7

Unit: 8

Topic:HTTP(hyper text transfer protocol)

Time: 10min

Specific Objecties:

• At the end of this class ,studnet will be able to understand the concept of HTTP protocol.

Teaching Material:

• Whiteboard,
• Marker and duster,
• Internet-enabled devices for demonstration purposes,
• Digital resource for explaning HTTP basic.

Introduction 3min:

• Begin with a discussion about how web pages load when browsing the internet.
• Ask students if they have noticed "http://" at the beginning of web addresses and what they think it means.

• Introduce the concept of HTTP protocol:

• HTTP protocol stands for Hypertext Transfer Protocol
• HTTP offers set of rules and standards which govern how any information can be transmitted on the World Wide Web.
• HTTP provides standard rules for web browsers & servers to communicate.
• HTTP uses Hypertext structured text which establishes the logical link between nodes containing text.
• It is also known as "stateless protocol" as each command is executed separately, without using reference of previous run command.

Advantages 2min:

• HTTP can be implemented with other protocol on the Internet, or on other networks.
• HTTP pages are stored on computer and internet caches, so it is quickly accessible Platform independent which allows cross-platform porting.
• Does not need any Runtime support Usable over Firewalls! Global applications are possible.
• Not Connection Oriented; so no network overhead to create and maintain session state and information.

Disadvantages 2min:

• There is no privacy as anyone can see content.
• Data integrity is a big issue as someone can alter the content. That's why HTTP protocol is an insecure method as no encryption methods are used.
• Not clear who you are talking about. Anyone who intercepts the request can get the username and password.

Classroom Activity 2min:

Ask studnet about HTTP.

Colclusion 1min:

• Summarize the key points covered during the lesson.
• Encourage students to explore further resources and consider the evolution of HTTP and its impact on web technologies.

Assessment:

• Task students with researching and presenting on the evolution of HTTP versions (e.g., HTTP/2, HTTP/3) and their improvements over previous versions.
