Http Meaning In Computer

HTTP: The Foundation of Web Communication

HTTP: Explained

HTTP (Hypertext Transfer Protocol) is the underlying protocol that enables communication between web browsers and web servers. It defines the rules and syntax for transmitting data over the internet, facilitating the transfer of web pages, files, and other resources. HTTP operates on a client-server model, where a web browser (client) sends a request to a web server, which responds with the requested resource.

Key Features of HTTP

- **Request-response model:** HTTP follows a request-response model, where the client sends an HTTP request to the server, and the server responds with an HTTP response. - **Stateless:** HTTP is a stateless protocol, meaning that each request is treated independently, and the server does not store any information about previous requests. - **Uniform Resource Identifier (URI):** HTTP uses URIs to identify resources on the internet. URIs can be absolute or relative. - **Hypertext Transfer Language (HTML):** HTML is the markup language used to create web pages. HTTP is responsible for transferring HTML documents from the server to the client. - **HTTP Methods:** HTTP defines several methods, such as GET, POST, PUT, and DELETE, which perform specific actions on the server. - **HTTP Status Codes:** HTTP uses status codes to indicate the success or failure of a request. Common status codes include 200 (OK), 404 (Not Found), and 500 (Internal Server Error).

HTTP Requests

HTTP requests are sent from the client to the server and contain the following information: - **Request line:** The request line includes the HTTP method, the URI of the requested resource, and the HTTP version. - **Request headers:** Request headers provide additional information about the request, such as the type of browser, the language preference, and the content type. - **Request body:** The request body contains the data that is being sent to the server.

HTTP Responses

HTTP responses are sent from the server to the client and contain the following information: - **Status line:** The status line includes the HTTP version, the status code, and a brief description of the status. - **Response headers:** Response headers provide additional information about the response, such as the content type, the content length, and the server information. - **Response body:** The response body contains the requested resource or any other data that the server is sending back to the client.
