Which of the following specifies how the communication will happen between web server and web browser?

The correct answer is Option 2) HTTP.

Key Points

• HTTP (HyperText Transfer Protocol) is the protocol that governs how data is transmitted between a web browser (client) and a web server.
• It defines:
  • How requests (like GET, POST) are made by the browser to the server
  • How the server responds with status codes (200 OK, 404 Not Found, etc.) and content (HTML, CSS, JS, JSON)
  • The structure and format of the request and response messages
• HTTP is a stateless, application-layer protocol built on top of TCP/IP.
• Modern web traffic often uses HTTPS, which is HTTP over an encrypted TLS/SSL connection.

Additional Information

• Option 1 – HTML: A markup language used to structure content on web pages, not for communication protocols.
• Option 3 – URL (Uniform Resource Locator): Specifies the address of a resource on the internet, not the communication mechanism.
• Option 4 – XML: A markup language for storing and transporting data; it does not define how communication occurs.
• Common HTTP Methods:
  • GET – Retrieve data
  • POST – Submit data to the server
  • PUT – Update a resource
  • DELETE – Remove a resource
