How many parts of URL?

A URL (Uniform Resource Locator) typically consists of several key parts: the scheme (protocol), the host (domain), the path, and optional components such as the port, query string, and fragment. For example, in the URL "https://www.example.com:443/path/to/resource?query=1#section", "https" is the scheme, "www.example.com" is the host, "443" is the port, "/path/to/resource" is the path, "?query=1" is the query string, and "#section" is the fragment. Each part serves a specific function in locating and accessing the resource on the internet.
