Suppose you're working on a Unix/Linux machine remotely through an SSH session, and then you need to get a resource (like a tar or gzip file) that's on the Internet to that machine. Well, you could download that file to your local machine, and then use scp to copy it to your remote Unix box. Or ... you can get the URL for the resource on your local workstation, copy the URL, and then use wget on the remote workstation and download it directly to that machine.
