What is HTTP?

What is HTTP?

The Hypertext Transfer Protocol (HTTP) is a foundational technology that powers the World Wide Web. It allows communication between a web browser (client) and a web server, enabling the exchange of information such as web pages, images, videos, and other resources. Whether you’re reading articles, shopping online, or streaming videos, HTTP ensures you can access these services with ease.

What is HTTP Used For?

HTTP is used to transfer hypertext documents and other resources from a server to a client. It powers:

• Web Browsing: Loading and displaying web pages.
• Data Transfer: Sharing resources like images, videos, and files.
• Form Submissions: Handling form data (e.g., logging in, searching).
• API Communication: Enabling apps to fetch or send data to servers.

How HTTP Works

HTTP operates on a request-response model:

1. Request: A client (browser) sends an HTTP request to a server, specifying the resource (e.g., a webpage).
2. Response: The server processes the request and sends back the resource or an error code (e.g., 404 Not Found).

Example:

• When you enter http://example.com, the browser sends an HTTP request to the server hosting example.com.
• The server responds with the HTML document, which the browser renders as a webpage.

Definition of HTTP and Port Used

• Definition: HTTP is a stateless protocol used for transferring hypertext and multimedia resources over the internet.
• Port Used: HTTP operates on port 80.

Comparison of HTTP vs. HTTPS

HTTP plays a critical role in connecting users to the internet, making it easy to access and share information. However, as cybersecurity concerns have grown, HTTPS has become the preferred choice for secure, encrypted communication.
