Download

Receiving data from a remote system for local storage.

Download

Download is a fundamental concept in computer networks, referring to the process of receiving data from a remote system such as a web server, FTP server, or email server. It contrasts with uploading, where data is sent to a remote system, and generally involves transferring entire files for local storage and later use, as opposed to streaming where data is used nearly immediately. The term can refer to a file offered for downloading, a file that has been downloaded, or the process of receiving such a file.

Lore & Background

Downloading on computer networks involves retrieving data from a remote system, like a web server, FTP server, or email server, unlike uploading, where data is sent to a remote server. A download can refer to a file made available for retrieval or one that has been received, encompassing the entire process of obtaining such a file. Downloading is not the same as data transfer; moving or copying data between two storage devices would be data transfer, but receiving data from the Internet or BBS is downloading. Websites that offer streaming media or media displayed in-browser, such as YouTube, increasingly place restrictions on the ability of users to save these materials to their computers after they have been received.

Reader's Guide

Downloading media files involves the use of linking and framing Internet material and relates to copyright law. Streaming and downloading can involve making copies of works that infringe on copyrights or other rights, and organizations running such websites may become vicariously liable for copyright infringement by causing others to do so. Open hosting servers allow people to upload files to a central server, which incurs bandwidth and hard disk space costs due to the files generated with each download. Anonymous and open hosting servers make it difficult to hold hosts accountable. Taking legal action against the technologies behind unauthorized 'file sharing' has proven successful for centralized networks like Napster, and untenable for decentralized networks like Gnutella or BitTorrent. The leading YouTube audio-ripping site agreed to shut down after being sued by a huge coalition of recording labels. Downloading and streaming relates to the more general usage of the Internet to facilitate copyright infringement, also known as 'software piracy'. As overt static hosting of unauthorized copies of works (i.e., centralized networks) is often quickly and uncontroversially rebuffed, legal issues have in recent years tended to deal with the usage of dynamic web technologies (decentralized networks, trackless BitTorrents) to circumvent the ability of copyright owners to directly engage particular distributors and consumers.

Frequently Asked Questions

What is Download in computer networking?

Download is the core process of receiving data from a remote system—such as a web server, FTP server, or email server—and storing it locally on your device for later use. It sits at the heart of everyday data transfer in computer networks.

How does Download differ from Uploading?

The two are opposites in direction: downloading pulls data from a remote system to your local machine, while uploading pushes data from your machine out to a remote system. Together they form the two directions of network data transfer.

What is the key difference between Download and Streaming?

A download transfers an entire file so it is saved locally and can be used later, whereas streaming delivers data in a continuous flow meant to be consumed almost immediately without permanent local storage. This distinction is why you can pause a downloaded video offline but not a streamed one.

What does the word 'download' actually refer to?

The term is used three ways: the act of receiving the file, the file that is being offered for retrieval, and the completed file sitting on your device after transfer. Context determines which meaning is intended.

What related concepts should I know alongside Download?

Key adjacent ideas include uploading, streaming, general data transfer, and copyright infringement, since downloading copyrighted material without authorization is a major legal concern tied to the technology. Understanding these links helps place downloading within the broader networking and legal landscape.
