NewsgroupsThe topics which are discussed in the Usenet are categorised in newsgroups. Every newsgroup is dedicated to a specific topic and can therefore be compared with a thread in an Internet forum. You can find out more about newsgroups.
NewsserversAll files are retained on the Usenet on newsservers.
NNTPNetwork News Transfer Protocol (NNTP) is the transfer protocol for messages in newsgroups. It communicates between the client and server, sending and receiving messages.
NZB filesNZB is a file format which saves information about Usenet articles with files. NZB files contain information on where the individual pieces of files are saved. NZB files help the newsreader software to show all the parts collected and to download them.
PAR filesDuring the transport between Usenet servers, individual parts of files can be damaged. Par files (parody files) allow these RAR files to be easily repaired.
RARis a compression format similar to ZIP, which allows the size of individual files to be reduced. This enables shorter download time.
The retention time provides information on how long a message or a file remains available in the newsgroups and/or is saved there.
