When using wget, what must you provide to download a file?

To download a file using the wget command, you must provide the website URL. This is essential because wget relies on the URL to locate and retrieve the specified file from the internet or a networked server. The URL contains crucial information such as the protocol (HTTP or HTTPS), the domain name, and the specific path to the file you intend to download.

Providing just the file name, file path, or FTP server address without the accompanying URL would not give wget enough information to locate the file over the internet. The URL is the complete address needed for wget to access the resources hosted on the web.
