What is the default TCP port for HTTP?

The default TCP port for HTTP is 80. This standard port is utilized by web servers for transmitting unencrypted hypertext, or web content, to clients, such as web browsers. When a user enters a web address (URL) without specifying a port, the browser automatically connects to port 80 to retrieve the requested resource using the HTTP protocol.

Port 443, on the other hand, is used for HTTPS, which is the secure version of HTTP and encrypts the data exchanged between the client and server. Port 21 is associated with FTP (File Transfer Protocol), used for transferring files between systems, while port 8080 typically serves as an alternative port for HTTP traffic, but it is not the default. Thus, 80 is universally recognized as the standard port for HTTP communications.
