Usenet, short for users network, is one of the oldest platforms served by the Internet. Originally designed at Duke University in 1979 and developed at Duke and North Carolina Universities a year later, its purpose was to exchange text messages between nodes (computers connected to the network). Usenet has grown to a big platform with a wide variety of forums or newsgroups numbering in the tens of thousands.
Today usenet is still used as a big bulletin board, in additional it is also used for data transfer by using Binary Files often in a compressed format like RAR or ZIP. A Binary file is a general term for a container. Binary Files can contain everything from movies, music, graphics to standard text documents.
