aria2 is a command-line application that can be used to download files over the following protocols: HTTP, Metalink, BitTorrent and FTP.
aria2 comes with a unique segmented download ability that allows its users to download portions of the file from multiple sources and protocols at once.
aria2 can be used to automatically validate data chunks while downloading like BitTorrent. The outcome of the segmented download ability is that you will get high download speeds, often higher that the ones achieved by the browser.
