File transfer

From Citizendium, the Citizens' Compendium

File transfer is a computer networking technique in which a file, composed of an ordered sequence of records, is transferred from one source computer to one or more destination computers. The simplest file transfer involves two computers, which can do no other communications during the transfer, copying the file from the source to the destination. If anything goes wrong with this transfer, it must be done over. Also, simple case provides no security either for access to the computers or to the file information as it moves through the network.
