HTTP
HTTP (Hypertext Transfer Protocol) is an application-layer protocol for transmitting hypermedia documents, such as HTML, across the internet. It defines how clients (e.g., web browsers) request resources from servers and how servers respond, forming the foundation of data communication on the World Wide Web. HTTP operates as a stateless, request-response protocol, typically over TCP/IP connections.
Developers should learn HTTP because it is essential for building and interacting with web applications, APIs, and services, enabling communication between clients and servers. It is used in scenarios like fetching web pages, submitting form data, and integrating with RESTful APIs, making it critical for front-end, back-end, and full-stack development. Understanding HTTP helps in debugging network issues, optimizing performance, and implementing security measures like HTTPS.
