'''Uploading''' refers to ''transmitting'' [[Data (computing)|data]] from one [[Computer|computer system]] to another through means of a [[Computer network|network]].<ref>{{cite web|title=What is Uploading? Definition from WhatIs.com|url=https://whatis.techtarget.com/definition/uploading|website=WhatIs.com|access-date=11 June 2020}}</ref> Common methods of uploading include: uploading via [[Web browser|web browsers]], [[FTP]] [[client–server model|clients]], and [[computer terminal|terminals]] ([[Secure copy|SCP]]/[[SSH File Transfer Protocol|SFTP]]). Uploading can be used in the context of (potentially many) [[Client_(computing)|clients]] that send files to a central [[Server_(computing)|server]]. While uploading can also be defined in the context of sending [[Computer file|files]] between [[Distributed computing|distributed]] clients, such as with a [[peer-to-peer]] (P2P) file-sharing [[Communication protocol|protocol]] like [[BitTorrent]], the term [[file sharing]] is more often used in this case. Moving files within a computer system, as opposed to over a network, is called [[file copying]]. 

Uploading directly contrasts with [[download]]ing, where data is ''received'' over a network. In the case of users uploading files over the [[internet]], uploading is often slower than downloading as many [[Internet service provider|internet service providers]] (ISPs) offer [[Asymmetric digital subscriber line|asymmetric connections]], which offer more network [[Bandwidth_(computing)|bandwidth]] for downloading than uploading.
