Port numbers
Extracted from the Wikipedia article Port (computer networking).
Use in URLs
Port numbers are a component in web or other uniform resource locators (URLs), but are omitted in most cases. 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 to port 8080 of the HTTP server, instead of the default value.
