====DECnet====
[[DECnet]] is a suite of network protocols created by [[Digital Equipment Corporation]], originally released in 1975 in order to connect two [[PDP-11]] [[minicomputer]]s.<ref>{{citation |url=http://archive.computerhistory.org/resources/text/dec/dec.digital_1957_to_the_present_(1978).1957-1978.102630349.pdf |url-status=dead |archive-url=https://web.archive.org/web/20170630025909/http://archive.computerhistory.org/resources/text/dec/dec.digital_1957_to_the_present_(1978).1957-1978.102630349.pdf |archive-date=2017-06-30 |title=Digital Equipment Corporation, Nineteen Fifty-Seven to the Present |publisher=Digital Equipment Corporation |date=1978 |page=53}}</ref> It evolved into one of the first [[peer-to-peer]] network architectures, thus transforming DEC into a networking powerhouse in the 1980s. Initially built with three [[Abstraction layer|layers]], it later (1982) evolved into a seven-layer [[Open Systems Interconnection|OSI]]-compliant networking protocol. The DECnet protocols were designed entirely by Digital Equipment Corporation. However, DECnet Phase II (and later) were [[open standard]]s with published specifications, and several implementations were developed outside DEC, including one for [[Linux]].
