What port number does HTTP typically use?

HTTP, which stands for Hypertext Transfer Protocol, is the foundational protocol used for transmitting data over the web. It typically operates on port 80. This is the default port assigned for unencrypted web traffic, allowing clients and servers to communicate effectively. When a user enters a web address in their browser, the browser uses port 80 to send and receive requests for HTML documents and web resources unless specified otherwise.

Port 443 is related to HTTPS, which is the secure version of HTTP that encrypts data for security purposes. Port 21 is used for FTP (File Transfer Protocol), which facilitates the transfer of files between computers. Port 25 serves as the standard for SMTP (Simple Mail Transfer Protocol), which is used for sending emails. Thus, the identification of port 80 as the standard for HTTP emphasizes the role of this port in regular, unencrypted web traffic.
