Question

HTTP uses which port number for communication

Answer 1

Use in URLs. Port numbers are sometimes seen in web or other uniform resource locators (URLs). By default, HTTP uses port 80 and HTTPS uses port 443, but a URL like http://www.example.com:8080/path/ specifies that the web browser connects instead to port 8080 of the HTTP server.

Answer 2

http uses port 80 and https uses port 443
