HTTP, which stands for Hypertext Transfer Protocol, is the communications protocol that sets the standard used by every computer that accesses web-based information. It is the underlying protocol used for transferring hypertext documents on the World Wide Web. HTTP allows for communication between a web server and a web browser, enabling the retrieval and display of web pages.
HTTP is a request-response protocol, which means that a client (such as a web browser) sends a request to a server, and the server responds with the requested data. This data can include HTML documents, images, videos, and other types of content. HTTP operates on top of the TCP/IP protocol, which provides the underlying network communication.
Key features of HTTP include:
1. Stateless: HTTP is a stateless protocol, which means that each request from the client is independent and does not carry any information about previous requests. This allows for scalability and simplicity in the design of web applications.
2. Request Methods: HTTP defines different methods that can be used in a request, such as GET, POST, PUT, DELETE, etc. These methods specify the action to be performed on the requested resource.
3. Uniform Resource Locators (URLs): HTTP uses URLs to identify and locate resources on the web. A URL consists of a scheme (such as "http"), a domain name or IP address, and a path to the resource.
4. Status Codes: HTTP uses status codes to indicate the outcome of a request. For example, a 200 status code indicates a successful request, while a 404 status code indicates that the requested resource was not found.
5. Headers: HTTP uses headers to transmit additional information about the request or response. Headers can include information such as content type, caching directives, cookies, and authentication credentials.
Overall, HTTP plays a crucial role in enabling communication between computers accessing web-based information. It provides a standardized way for clients and servers to exchange data, making the World Wide Web accessible and functional for users around the world.
