To transmit a file over a network. In a communications session, "download" and "upload" imply a remote/local scenario, in which data are being downloaded from the "remote" server into the user's "local" computer. Uploading is the reverse.
The time it takes to download depends on file size and network speed. Via analog dial-up modems, Web pages take several seconds, and a 10MB file can take an hour. DSL, cable and FiOS are from 15 to 600 times faster, reaching the same speed as downloading from a server within the local network (LAN).
From the Internet
Downloading images, articles and applications from the Internet is no more than "Click Here" on a Web page. The only thing users must know is what to do with the downloaded file. If the download is an app, it must be installed, which can happen automatically or require the user to take one more step and install the program. See download vs. upload

From the Local Network (LAN)
In a server in a private network, files are placed in sharable folders that can be downloaded to users' computers. Using a file manager, such as Explorer, users can locate the files by computer and folder name. See file manager
From the Computer to Mobile Devices
Transferring files to an iPod, smartphone or tablet plugged into the USB port of a computer is technically a copy function and not a download. The mobile device appears as just another storage drive in the same computer. See Internet speed
