HTTP (Hypertext Transfer Protocol)

Stateless Protocol : HTTP is stateless, meaning each request is independent and does not retain information about previous interactions.
Request-Response Model : Communication occurs through a client-server model, where the client sends a request and the server responds.
Text-Based : HTTP messages are human-readable and consist of methods like GET , POST , PUT , and DELETE.
Port 80 : By default, HTTP operates on port 80.

Note

HTTP does not encrypt data, making it vulnerable to eavesdropping.

HTTPS (Hypertext Transfer Protocol Secure)

Secure Version of HTTP : HTTPS adds a layer of encryption using protocols like SSL/TLS.
Data Integrity and Confidentiality : Ensures that data is encrypted during transmission, protecting it from interception.
Authentication : Uses digital certificates to verify the identity of the server.
Port 443 : HTTPS operates on port 443.

Note

HTTPS is essential for secure transactions, such as online banking and shopping.

HTML (Hypertext Markup Language)

Markup Language : HTML is used to structure web content using tags like <h1>, <p>, and <a>.
Static Content : Defines the content and layout of web pages but does not handle dynamic behavior.
