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 (universal serial bus) 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 (uniform resource locator), allowing them to download the document/file/program. Sometimes, 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, a digital distribution platform that allows users to purchase and download games.
