In computer networks A computer network, often simply referred to as a network, is a collection of computers and devices connected by communications channels that facilitates communications among users and allows users to share resources with other users. Networks may be classified according to a wide variety of characteristics. This article provides a general, to download means to receive data to a local system from a remote system, or to initiate such a data transfer. Examples of a remote system from which a download might be performed include a webserver A web server is a computer program that delivers content, such as web pages, using the Hypertext Transfer Protocol (HTTP), over the World Wide Web. The term web server can also refer to the computer or virtual machine running the program. In large commercial deployments, a server computer running a web server can be rack-mounted with other servers, FTP server File Transfer Protocol is a standard network protocol used to copy a file from one host to another over a TCP/IP-based network, such as the Internet. FTP is built on a client-server architecture and utilizes separate control and data connections between the client and server applications, which solves the problem of different end host, email Electronic mail, commonly called email or e-mail, is a method of exchanging digital messages across the Internet or other computer networks. Email systems are based on a store-and-forward model in which email server computer systems accept, forward, deliver and store messages on behalf of users, who only need to connect to the email infrastructure, server, or other similar systems. A download can mean either any file that is offered for downloading or that has been downloaded, or the process of receiving such a file.
The inverse operation, uploading, can refer to the sending of data from a local system to a remote system such as a server or another client with the intent that the remote system should store a copy of the data being transferred, or the initiation of such a process. The words first came into popular usage among computer users A user is a person who uses a computer or Internet service. A user may have a user account that identifies the user by a username , screen name (also screenname), or "handle", which is derived from the identical Citizen's Band radio term. To log in to an account, a user is typically required to authenticate himself/herself/itself with a with the increased popularity of Bulletin Board Systems A Bulletin Board System, or BBS, is a computer system running software that allows users to connect and log in to the system using a terminal program. Once logged in, a user can perform functions such as uploading and downloading software and data, reading news and bulletins, and exchanging messages with other users, either through electronic mail (BBSs), facilitated by the widespread distribution and implementation of dial-up Dial-up Internet access is a form of Internet access that uses telephone lines. The user's computer or router uses an attached modem connected to a telephone line to dial into an Internet service provider's node to establish a modem-to-modem link, which is then used to route Internet Protocol packets between the user's equipment and hosts access the in the 1970s.

Download
The use of the terms uploading and downloading often imply that the data sent or received is to be stored permanently, or at least stored more than temporarily. In contrast, the term downloading is distinguished from the related concept of streaming Streaming media are multimedia that are constantly received by, and normally presented to, an end-user while being delivered by a streaming provider . The name refers to the delivery method of the medium rather than to the medium itself. The distinction is usually applied to media that are distributed over telecommunications networks, as most, which indicates the receiving of data that is used near immediately as it is received, while the transmission is still in progress and which may not be stored long-term, whereas in a process described using the term downloading, this would imply that the data is only usable when it has been received in its entirety.
Increasingly, websites that offer streaming media or media displayed in-browser, such as YouTube YouTube is a video-sharing website on which users can upload, share, and view videos. Three former PayPal employees created YouTube in February 2005. In November 2006, YouTube, LLC was bought by Google Inc. for $1.65 billion, and is now operated as a subsidiary of Google. The company is based in San Bruno, California, and uses Adobe Flash Video, 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".
Sideload
When applied to local transfers (sending data from one local system to another local system), it is often difficult to decide if it is an upload or download, as both source and destination are in the local control of the user. Technically if the user uses the receiving device to initiate the transfer then it would be a download and if they used the sending device to initiate it would be an upload. However, as most non-technical users tend to use the term download to refer to any data transfer, the term "sideload Sideloading is a term used in Internet culture, similar to "upload" and "download", but in reference to the process of transferring data between two local devices, in particular between a computer and a mobile device such as a cellphone, smartphone, PDA, or portable media player" is sometimes being used to cover all local to local transfers to end this confusion.
Remote upload
When there is a transfer of data from a remote system to another remote system, the process is called "remote uploading". This is used by some online file hosting services A file hosting service, online file storage provider or cyberlocker is an Internet hosting service specifically designed to host static content, typically large files that are not web pages. Typically they allow web and FTP access. They can be optimized for serving many users or be optimized for single-user storage (as is implied by the term ".
Remote uploading is also used in situations where the computers that need to share data are located on a distant high speed local area network A local area network is a computer network covering a small physical area, like a home, office, or small groups of buildings, such as a school, or an airport. The defining characteristics of LANs, in contrast to wide area networks (WANs), include their usually higher data-transfer rates, smaller geographic area, and lack of a need for leased, and the remote control is being performed using a comparatively slow dialup Dial-up Internet access is a form of Internet access that uses telephone lines. The user's computer or router uses an attached modem connected to a telephone line to dial into an Internet service provider's node to establish a modem-to-modem link, which is then used to route Internet Protocol packets between the user's equipment and hosts modem connection.
For example:
- The user remotely accesses a file hosting service at MyRemoteHost.
- The user finds a public file at PublicRemoteHost and wants to keep a copy in their MyRemoteHost.
- To have it done they "remote upload" the file from PublicRemoteHost to MyRemoteHost.
- None of the hosts are located on the user's the local network.
Without remote uploading functionality, the user would be required to download the file first to their local host and then re-upload it to the remote file hosting server.
Where the connection to the remote computers is via a dialup connection, the transfer time required to download locally and then re-upload could increase from seconds, to hours or days.
