There was only one possible answer, but Jack's horrified mind refused to believe it until he had fed the radar plots of the skiff's course into the computer.

It is worth mentioning that the Nepōhualtzintzin amounted to the rank from 10 to the 18 in floating point, which calculated stellar as well as infinitesimal amounts with absolute precision, meant that no round off was allowed, when translated into modern computer arithmetic.

Alan Mathison Turing, OBE, FRS ( ; 23 June 1912 – 7 June 1954 ), was a British mathematician, logician, cryptanalyst, and computer scientist.

He was highly influential in the development of computer science, giving a formalisation of the concepts of " algorithm " and " computation " with the Turing machine, which can be considered a model of a general purpose computer.

The Analytical Engine was a proposed mechanical general-purpose computer designed by English mathematician Charles Babbage.

It was first described in 1837 as the successor to Babbage's Difference Engine, a design for a mechanical computer.

The Apple I's built-in computer terminal circuitry was distinctive.

As Wozniak was the only person who could answer most customer support questions about the computer, the company offered Apple I owners discounts and trade-ins for Apple IIs to persuade them to return their computers, contributing to their scarcity.

The high price was likely due to the rare documents and packaging offered in the sale in addition to the computer, including the original packaging ( with the return label showing Steve Jobs ' parents ' address, the original Apple Computer Inc ' headquarters ' being their garage ), a personally typed and signed letter from Jobs ( answering technical questions about the computer ), and the original invoice showing ' Steven ' as the salesman.

The computer was brought to Polytechnic University of Turin where it was fixed and used to run the BASIC programming language .</ li >

The computer was designated an IEEE Milestone in 1990.

Atanasoff and Clifford Berry's computer work was not widely known until it was rediscovered in the 1960s, amidst conflicting claims about the first instance of an electronic computer.

At that time, the ENIAC was considered to be the first computer in the modern sense, but in 1973 a U. S. District Court invalidated the ENIAC patent and concluded that the ENIAC inventors had derived the subject matter of the electronic digital computer from Atanasoff ( see Patent dispute ).

It was not a Turing complete computer, which distinguishes it from more general machines, like contemporary Konrad Zuse's Z3 ( 1941 ), or later machines like the 1946 ENIAC, 1949 EDVAC, the University of Manchester designs, or Alan Turing's post-War designs at NPL and elsewhere.

The machine was, however, the first to implement three critical ideas that are still part of every modern computer:

George W. Snedecor, the head of Iowa State's Statistics Department, was very likely the first user of an electronic digital computer to solve real world mathematics problems.

ALGOL ( short for ALGOrithmic Language ) is a family of imperative computer programming languages originally developed in the mid 1950s which greatly influenced many other languages and was the standard method for algorithm description used by the ACM, in textbooks, and academic works for the next 30 years and more.

The first model was launched in 1985 as a high-end home computer and became popular for its graphical, audio and multi-tasking abilities.

Whereas Wozniak originally referred to his Integer BASIC as " Game BASIC ," having written it so he could write a Breakout clone for his new computer, few action games were written in Applesoft BASIC for several reasons:

Alpha, originally known as Alpha AXP, is a 64-bit reduced instruction set computer ( RISC ) instruction set architecture ( ISA ) developed by Digital Equipment Corporation ( DEC ), designed to replace the 32-bit VAX complex instruction set computer ( CISC ) ISA and its implementations.

It is found in an originally academic movement unrelated to computer security and most visibly associated with free software and open source.

Named IBM 4680 OS, IBM originally chose DR Concurrent DOS 286 as the basis of their IBM 4680 computer for IBM Plant System products and Point-of-Sale terminals in 1986.

* P. H. I. R. M., a 1980s computer hacking group originally known as Kilobaud

Lisp was originally created as a practical mathematical notation for computer programs, influenced by the notation of Alonzo Church's lambda calculus.

1-2-3 was originally written by Jonathan Sachs, who had written two spreadsheet programs previously while working at Concentric Data Systems, Inc. To aid its growth, in the UK, and possibly elsewhere, Lotus 1-2-3 was the very first computer software to use television consumer advertising.

In computer programming, lint was the name originally given to a particular program that flagged some suspicious and non-portable constructs ( likely to be bugs ) in C language source code.

Microcode was originally developed as a simpler method of developing the control logic for a computer.

MIPS ( originally an acronym for Microprocessor without Interlocked Pipeline Stages ) is a reduced instruction set computer ( RISC ) instruction set architecture ( ISA ) developed by MIPS Technologies ( formerly MIPS Computer Systems, Inc .).

In computer gaming, Murder Motel was an online text game by Sean D. Wagle, hosted on various dial-up bulletin board systems ( 1980s, originally Color64, ported to various other platforms ).

It is revealed that in the past, Wintermute had originally contacted Corto through a bedside computer during his convalescence, eventually convincing Corto that he was Armitage.

O2EM, ( originally not open source ) was created in 1997 by computer programmer Daniel Boris and further enhanced by Andre Rodrigues de La Rocha.

It was the first widely sold computer in the DEC PDP series of computers ( the PDP-5 was not originally intended to be a general-purpose computer ).

is a Japanese computer and video game developer established in Ōta, Tokyo, Japan in 1990, originally known as Sega AM8.

Canonical flowchart symbols: The graphical aide called a flowchart offers a way to describe and document an algorithm ( and a computer program of one ).

) Like the central processing unit ( CPU ) in a modern computer, the mill would rely upon its own internal procedures, to be stored in the form of pegs inserted into rotating drums called " barrels ", to carry out some of the more complex instructions the user's program might specify.

Initially Aster computer b. v. was called MCP ( Music print Computer Product ), because it was specialized in producing computer assisted printing of sheet music.

* The Outpost computer game and its sequel both focus on building arcologies ( called ' colonies ' in the game ) on various planets to contain what remains of Humanity after Earth is obliterated by an asteroid.

* 1959 – A team of computer manufacturers, users, and university people led by Grace Hopper meets to discuss the creation of a new programming language that would be called COBOL.

In a category with exponentials, using the isomorphism ( in computer science, this is called currying ), the Ackermann function may be defined via primitive recursion over higher-order functionals as follows:

Tradition ( e. g. Donald Knuth's ( 1973 ) hypothetical MIX computer ), for example, uses two instructions called load accumulator from register / memory ( e. g. " LDA r ") and store accumulator to register / memory ( e. g. " STA r ").

( In computer science, this identification between a function from X × Y to Z and a function from X to Z < sup > Y </ sup > is called Currying.

Schelter is credited with the development of the GNU Common Lisp ( gcl ) implementation of Common Lisp and the GPL'd version of the computer algebra system Macsyma called GNU Maxima.

A type of computer simulation called discrete event simulation represents the operation of a system as a chronological sequence of events.

If a DFS ROM is installed, will cause the computer to search for and load a file called on the floppy disk in drive 0.

A computer is a machine that manipulates data according to a set of instructions called a computer program.

" Since the term " CPU " is generally defined as a device for software ( computer program ) execution, the earliest devices that could rightly be called CPUs came with the advent of the stored-program computer.

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data.

Computer software is so called to distinguish it from computer hardware, which encompasses the physical interconnections and devices required to store and execute ( or run ) the software.

Computer hardware companies not only bundled their software, they also placed demands on the location of the hardware in a refrigerated space called a computer room.

The mathematicians and computer programmers that do this kind of work are called gaming mathematicians and gaming analysts.

A computation can be seen as a purely physical phenomenon occurring inside a closed physical system called a computer.

A keyset or chorded keyboard ( also called a chorded keyset, chord keyboard or chording keyboard ) is a computer input device that allows the user to enter characters or commands formed by pressing several keys together, like playing a " chord " on a piano.

Douglas Engelbart introduced the chorded keyset as a computer interface in 1968 at what is often called " The Mother of All Demos ".

Such a computer is sometimes called a Writable Instruction Set Computer or WISC.

In mathematics and computer science, currying is the technique of transforming a function that takes multiple arguments ( or an n-tuple of arguments ) in such a way that it can be called as a chain of functions each with a single argument ( partial application ).
