Delhi Police Head Constable Mock Test - 8 - Question 30

 ______________ protocol defines how messages are formatted and transmitted, and what actions Web servers and browsers should take in response to various commands.

Detailed Solution for Delhi Police Head Constable Mock Test - 8 - Question 30
The HTTP Protocol
The HTTP protocol, which stands for HyperText Transfer Protocol, is a protocol that defines how messages are formatted and transmitted over the internet. It specifies the actions that web servers and browsers should take in response to various commands. Here's a detailed explanation of the HTTP protocol:
1. Message Formatting:
- HTTP messages consist of a request or a response.
- The request message is sent by a client (such as a web browser) to a server, requesting a specific action to be performed.
- The response message is sent by the server to the client, providing the requested information or indicating an error.
2. Message Transmission:
- HTTP messages are transmitted over TCP/IP, which is the underlying protocol for internet communication.
- TCP/IP ensures that the messages are divided into packets and delivered reliably to the intended recipient.
3. Actions for Web Servers:
- Web servers receive HTTP requests from clients and process them.
- They perform actions such as retrieving resources (HTML files, images, etc.) from the server's file system or executing server-side scripts.
- The server then constructs an HTTP response message and sends it back to the client.
4. Actions for Web Browsers:
- Web browsers initiate HTTP requests to web servers to retrieve web pages.
- They send a request message specifying the desired resource (e.g., a URL).
- The browser then receives the response message from the server and renders the web page for the user to view.
5. Commands and Responses:
- HTTP defines a set of commands (methods) that clients can use in their requests, such as GET, POST, PUT, and DELETE.
- The server responds to these commands with specific status codes, indicating the success or failure of the request (e.g., 200 for success, 404 for not found).
Conclusion:
The HTTP protocol is essential for communication between web servers and web browsers. It defines the format and transmission of messages, as well as the actions to be taken by servers and browsers. It enables the retrieval and rendering of web pages, making it a fundamental protocol for the World Wide Web.
