Segmented Downloading
Segmented file-transfer (also known as multisource file-transfer or swarming file-transfer) is the coordinated transmission of a computer file sourced from multiple servers to a single destination. It can be applied as well when downloading the same file from the same server in various parts, like some download managers do. A computer program downloads (retrieves) different portions of the file from various sources simultaneously, and assembles the file on the destination computer data storage device.
