A digital download is an electronic form of acquiring a document, file or software package. Digital downloads occur over the Internet, a network or a USB device (hard drive or thumb drive) most commonly.
Many companies today allow users to retrieve documents, files or software programs (including computer games) as a digital download. Users access a specific Internet link (a URL), allowing them to download the document/file/program. In some cases, a payment must be made before beginning the download process.
Some companies have specific websites or platforms dedicated to providing digital download access to users. An excellent example would be Steam, which is a digital distribution platform that allows users to purchase and download games.
