Which IP protocol is used by web browsers and web servers to exchange files?

FTP
IMAP
HTTP
SMTP

The correct answer is: HTTP

The correct answer is HTTP, which stands for Hypertext Transfer Protocol. This protocol is specifically designed for transferring hypertext files, such as HTML documents, over the web. When a user enters a website address in their web browser, the browser uses HTTP to request files from the corresponding web server, allowing the display of web pages. HTTP operates on a request and response model, where the browser sends a request to a server, and the server sends back the requested resources. This makes it an essential protocol for any web browsing activity, enabling seamless communication between user devices and web servers for displaying content. While the other protocols mentioned might serve various purposes, they are not designed specifically for the exchange of files between web browsers and web servers. For instance, FTP (File Transfer Protocol) is used primarily for transferring files between machines, often used in scenarios where users need to upload or download files to/from servers, not for web page content delivery. IMAP (Internet Message Access Protocol) and SMTP (Simple Mail Transfer Protocol) are related to email services, dealing with receiving and sending email, respectively. Hence, HTTP stands out as the correct choice for web-based file exchange.
