Which protocol is primarily used for web page transmission?

The protocol primarily used for web page transmission is HTTP, which stands for Hypertext Transfer Protocol. HTTP is the foundation of data communication on the World Wide Web. It is designed for transmitting hypertext, which includes HTML documents, images, videos, and other resources that make up web pages. When a user enters a URL into a web browser, the browser uses HTTP to request the desired web page from the server, which then responds with the requested content.

HTTP functions as a request-response protocol, where the browser acts as a client making requests and the web server provides responses with the requested data. Additionally, HTTP supports various methods, such as GET and POST, which define the type of action the client wants to perform on the resource.

In contrast, other protocols like TCP (Transmission Control Protocol) provide the underlying transport mechanism for data transmission but are not specifically designed for web content. FTP (File Transfer Protocol) is used for transferring files between a client and a server but is not optimized for web page transmission. SSH (Secure Shell) is primarily used for secure access to remote computers and does not focus on web page transmission. Thus, HTTP is the quintessential protocol for delivering web pages over the Internet.
