In networks, uploading and downloading refer to the two canonical directions (corresponding to send and receive, respectively) that information can move, and further defines such data as being copied and compiled (indicated by the term "loading") to create a complete file, after a period of time. Downloading is distinguished from the related concept of streaming, which indicates a download in which the data is sequentially usable as it downloads, or "streams," and that (typically) the data is not stored. To download is to receive data to a local system from a remote system, such as a webserver, FTP server, email server, or other similar systems. A download is any file that is offered for downloading or that has been downloaded. The inverse operation, uploading, is the sending of data from a local system to a remote system, such as a server, or peer, with the intent that the remote system should save a copy of whatever is being transferred.
