The primary protocol used on the World Wide Web is HTTP, which stands for HyperText Transfer Protocol. This protocol is designed for transferring hypertext documents on the web and is the foundation of data communication for the World Wide Web.
Here's a step-by-step explanation:
Purpose : HTTP is used to load web pages using hypertext links. It allows the fetching of resources, such as HTML documents, and also encompasses other resources like scripts, stylesheets, and images that are necessary to render the complete webpage.
Operation : HTTP is a request-response protocol, where a client, typically a web browser, makes an HTTP request to a server. The server then returns a response, which usually contains the requested resource and some control information through headers.
Structure : An HTTP operation involves HTTP requests (from the client) and HTTP responses (from the server). The requests and responses are structured in a simple format using plain text, making HTTP both a simple and flexible protocol.
Versions : The protocol has evolved over time, with HTTP/1.0 originally designed for simple exchanges, HTTP/1.1 introducing persistent connections for improved speed, and HTTP/2 providing multiplexing and improved efficiency. The latest version, HTTP/3, incorporates new technology for improved performance.
Use on the Web : HTTP is utilized by all web servers and browsers today as it enables the opening and navigation of web pages and websites across the globe.
In summary, the correct choice for the primary protocol used on the World Wide Web from the options provided is (C) HTTP.
