Jerry Saltzer
Jerome Howard "Jerry" Saltzer (born October 9, 1939) is an American computer scientist. Career Jerry Saltzer received an ScD in Electrical Engineering from MIT in 1966. His dissertation '''Traffic Control in a Multiplexed System was advised by Fernando Corbató. In 1966, he joined the faculty of the Department of Electrical Engineering and Computer Science at MIT. One of Saltzer's earliest involvements with computers was with MIT's Compatible Time-Sharing System in the early 1960s. In the later 1960s and early 1970s, he was one of the team leaders of the Multics operating system project. Multics, though not particularly commercially successful in itself, has had a major impact on all subsequent operating systems; in particular, it was an inspiration for Ken Thompson to develop Unix. Saltzer's contributions to Multics included the now-standard kernel stack switching method of process switching, as well as oft-cited work on the security architecture for shared information syst ...

IEEE
The Institute of Electrical and Electronics Engineers (IEEE) is a 501(c)(3) professional association for electronic engineering and electrical engineering (and associated disciplines) with its corporate office in New York City and its operations center in Piscataway, New Jersey. The mission of the IEEE is ''advancing technology for the benefit of humanity''. The IEEE was formed from the amalgamation of the American Institute of Electrical Engineers and the Institute of Radio Engineers in 1963. Due to its expansion of scope into so many related fields, it is simply referred to by the letters I-E-E-E (pronounced I-triple-E), except on legal business documents. , it is the world's largest association of technical professionals with more than 423,000 members in over 160 countries around the world. Its objectives are the educational and technical advancement of electrical and electronic engineering, telecommunications, computer engineering and similar disciplines. History Or ...

TYPSET
TYPSET is an early document editor that was used with the 1964-released RUNOFF program, one of the earliest text formatting programs to see significant use. Of two earlier print/formatting programs DITTO and TJ-2, only the latter had, and introduced, text justification; RUNOFF also added pagination. The name RUNOFF, and similar names led to other formatting program implementations. By 1982 ''Runoff'' largely became associated with Digital Equipment Corporation and Unix computers. DEC used the terms ''VAX DSR'' and ''DSR'' to refer to ''VAX DIGITAL Standard Runoff''. History CTSS The original RUNOFF type-setting program for CTSS was written by Jerome H. Saltzer circa 1964. Bob Morris and Doug McIlroy translated that from MAD to BCPL. Morris and McIlroy then moved the BCPL version to Multics when the IBM 7094 on which CTSS ran was being shut down. Multics Documentation for the Multics version of RUNOFF described it as "types out text segments in manuscript form." Other ...

Nroff
nroff (short for "new roff") is a text-formatting computer program, program on Unix and Unix-like operating systems. It produces output suitable for simple fixed-width computer printer, printers and computer terminal, terminal windows. It is an integral part of the Unix help system, being used to format man pages for display. nroff and the related troff were both developed from the original roff (software), roff. While nroff was intended to produce output on terminals and line printers, troff was intended to produce output on typesetting systems. Both used the same underlying markup language, markup and a single source file could normally be used by nroff or troff without change. History nroff was written by Joe Ossanna for Version 2 Unix, in Assembly language and then ported to C (programming language), C. It was a descendant of the RUNOFF program from Compatible Time-Sharing System, CTSS, the first computerized text-formatting program, and is a predecessor of the Unix troff d ...

Roff (computer Program)
roff is a typewriter-oriented markup language. As the first Unix text-formatting computer program, it is a predecessor of the nroff and troff document processing systems. Roff was a Unix version of the runoff text-formatting program from Multics, which was a descendant of RUNOFF for CTSS (the first computerized text-formatting application). History CTSS ''roff'' is a descendant of the RUNOFF program by Jerry Saltzer, which ran on CTSS. Douglas McIlroy and Robert Morris wrote runoff for Multics in BCPL based on Saltzer's program written in MAD assembler. Their program in turn was "transliterated" by Ken Thompson into PDP-7 assembler language for his early Unix operating system, circa 1970. APDF/ref> When the first PDP-11 was acquired for Unix in late 1970 (a PDP-11/20), the justification cited to management for the funding required was that it was to be used as a word processing system, and so ''roff'' was quickly transliterated again, into PDP-11 assembly, in 1971.

Catalogue Raisonné
A ''catalogue raisonné'' (or critical catalogue) is a comprehensive, annotated listing of all the known artworks by an artist either in a particular medium or all media. The works are described in such a way that they may be reliably identified by third parties, and such listings play an important role in authentification. Etymology The term ''catalogue raisonné'' is French, meaning "reasoned catalogue"Catalogue raisonné , ''Online Merriam-Webster Dictionary''. (i.e. containing arguments for the information given, such as attributions), but is part of the of the English-speaking art world. The spelling is never Americanized to "catalog", even ...

End-to-end Principle
The end-to-end principle is a design framework in computer networking. In networks designed according to this principle, guaranteeing certain application-specific features, such as reliability and security, requires that they reside in the communicating end nodes of the network. Intermediary nodes, such as gateways and routers, that exist to establish the network, may implement these to improve efficiency but cannot guarantee end-to-end correctness. The essence of what would later be called the end-to-end principle was contained in the work of Paul Baran and Donald Davies on packet-switched networks in the 1960s. Louis Pouzin pioneered the use of the end-to-end strategy in the CYCLADES network in the 1970s. The principle was first articulated explicitly in 1981 by Saltzer, Reed, and Clark. The meaning of the end-to-end principle has been continuously reinterpreted ever since its initial articulation. Also, noteworthy formulations of the end-to-end principle can be found ...

Local Area Network
A local area network (LAN) is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus or office building. By contrast, a wide area network (WAN) not only covers a larger geographic distance, but also generally involves leased telecommunication circuits. Ethernet and Wi-Fi are the two most common technologies in use for local area networks. Historical network technologies include ARCNET, Token Ring and AppleTalk. History The increasing demand and usage of computers in universities and research labs in the late 1960s generated the need to provide high-speed interconnections between computer systems. A 1970 report from the Lawrence Radiation Laboratory detailing the growth of their "Octopus" network gave a good indication of the situation. A number of experimental and early commercial LAN technologies were developed in the 1970s. Cambridge Ring was developed at Cambridge University starting in 1974. Ethe ...
