To download is to receive data to a local system from a remote system, such as a webserver, FTP server, mail server, or other similar systems. A download is any file that is offered for downloading or that has been downloaded. The word's primary usage comes in the form of a verb. Increasingly, websites that offer streaming media or media displayed in-browser, such as YouTube, and which place restrictions on the ability of users to save these materials to their computers after they have been received, say that downloading is not permitted.^[1] In this context, "download" implies specifically "receive and save" instead of simply "receive."
