Algorithm, Concepts

Standing Scholarly debate

Concerns Origin Year

Currently States 1936

Informal algorithms are ancient practice, Euclid's algorithm dates to around 300 BCE; the formal mathematical definition of an algorithm as a precisely specified, mechanically followable procedure dates to 1936, when Turing and Church independently formalized computability.

Informal algorithms are ancient, Euclid's algorithm dates to around 300 BCE, but the field as a distinct mathematical discipline is usually dated to 1936, when Alan Turing and, independently, Alonzo Church gave the first formal definitions of what it means for a procedure to be computable at all.

Assembly Language, Programming Languages

Standing Scholarly debate

Concerns First Released

Currently States 1947

Assembly language has no single agreed year or inventor. Kathleen and Andrew Donald Booth's 1947 Coding for A.R.C. is the earliest documented work using a language to represent machine code instructions symbolically, but the term assembler itself is usually credited to Wilkes, Wheeler and Gill's 1951 book, and similar mnemonic coding schemes emerged independently on other early machines in the same years. 1947 is used here as the earliest documented instance, not as a settled single origin.

Atanasoff Berry Computer, Systems

Standing Scholarly debate

Concerns Significance

Currently States The first automatic electronic digital computer, with priority backed by the 1973 Honeywell v. Sperry Rand finding; historians debate the title because the machine was neither programmable nor Turing complete.

The 1973 court finding is a matter of public record; the historians' debate over whether a non programmable machine can hold the title is equally on the record. Both are stated rather than smoothed over.

BINAC, Systems

Standing Scholarly debate

Concerns Significance

Currently States Sometimes claimed as the world's first commercial digital computer, a claim this atlas states honestly alongside the article's own record that BINAC was limited in scope and never fully functional after delivery, the same debated-attribution voice this atlas already applies to ENIAC and Colossus.

The claim of being the first commercial digital computer is the article's own qualified framing (sometimes claimed), set against its own statement that the machine never worked fully after delivery.

Binary Search Tree, Concepts

Standing Scholarly debate

Concerns Origin Year

Currently States 1960

Several researchers (Windley, Booth, Colin, Hibbard) described the structure independently around 1960; formal attribution to Berners-Lee and Wheeler names one specific 1960 application (magnetic tape storage) rather than settling a single inventor for the underlying idea.

Client-Server Model, Concepts

Standing Scholarly debate

Concerns Origin Year

Currently States 1964

The underlying request-and-response division of labor is visible by 1964 (OS/360 remote job entry) and the server-host/user-host terminology by the early ARPANET RFCs, but the word client was not formally defined until a 1978 Xerox PARC paper and server only entered general use by 1992; no single year cleanly founds the model.

Cloud Computing, Fields

Concerns Origin Year

Currently States 1996

The cloud metaphor for virtualized services dates to 1994 (General Magic's Telescript environment); the expression cloud computing itself became widely known in 1996 via a Compaq Computer Corporation business plan.

Cryptography, Fields

Standing Scholarly debate

Concerns Origin Year

Currently States 1976

Cryptography as a practice is ancient, but its treatment as a computational academic field is usually dated to the 1970s: the Data Encryption Standard effort of the early 1970s and the 1976 Diffie-Hellman publication that opened public key cryptography, so the origin year depends on whether the ancient practice or the modern computational field is being dated.

The term itself appeared around 1990 in the database community; the statistical and analytical methods it draws on trace back much further (Bayes' theorem, 18th century; regression analysis, 19th century).

Distributed Computing, Fields

Standing Scholarly debate

Concerns Core Concern

Currently States Which computational problems can be solved across networks of independent computers, and how efficiently, given that components communicate only by passing messages and may fail independently.

The article itself states there is no single agreed definition of a distributed system, and no clear line separates distributed computing from concurrent and parallel computing.

Dynamic Programming, Concepts

Standing Scholarly debate

Concerns Core Principle

Currently States Problems exhibiting optimal substructure and overlapping sub-problems can be solved efficiently by recursive decomposition combined with caching of intermediate results, developed by Richard Bellman in the 1950s.

Bellman's own account of why he chose the name dynamic programming is contested: Russell and Norvig note his story cannot be strictly true, since his first paper using the term (1952) predates the political circumstances he described, and Harold Kushner has suggested other motives, such as wanting to distinguish the work from Dantzig's linear programming.

The Autonetics D-17 (1961, Minuteman missile guidance, mass-produced) predates the more commonly cited Apollo Guidance Computer (circa 1965), which sources describe as the first RECOGNIZABLY MODERN embedded system rather than the first one outright; the field has no single undisputed founding year.
