Read-only memory ( ROM ) is a type of non-volatile memory used in computers and other electronic devices . Data stored in ROM cannot be electronically modified after the manufacture of the memory device . Read-only memory is useful for storing software that is rarely changed during the life of the system, also known as firmware . Software applications, such as video games , for programmable devices can be distributed as plug-in cartridges containing ROM .
116-691: Neuromancer is a 1984 science fiction novel by American-Canadian writer William Gibson . Considered one of the earliest and best-known works in the cyberpunk genre, it is the only novel to win the Nebula Award , the Philip K. Dick Award , and the Hugo Award . It was Gibson's debut novel and the beginning of the Sprawl trilogy . Set in the future, the novel follows Henry Case, a washed-up hacker hired for one last job, which brings him in contact with
232-765: A computer -like screen , computer viruses , video chat , tanning beds , home treadmills , and more. In 1963, the time travel-themed Doctor Who premiered on BBC Television. The original series ran until 1989 and was revived in 2005. It has been extremely popular worldwide and has greatly influenced later TV science fiction. Other programs in the 1960s included The Outer Limits (1963–1965), Lost in Space (1965–1968), and The Prisoner (1967). Star Trek (the original series), created by Gene Roddenberry , premiered in 1966 on NBC Television and ran for three seasons. It combined elements of space opera and Space Western . Only mildly successful at first,

Since the 1980s, science fiction films , along with fantasy , horror , and superhero films, have dominated Hollywood's big-budget productions. Science fiction films often " cross-over " with other genres, including film noir ( Blade Runner - 1982), family film ( E.T.
580-544: A 4-part radio play of Neuromancer. Gibson read an abridged version of his novel Neuromancer on four audio cassettes for Time Warner Audio Books (1994), which are now unavailable. An unabridged version of this book was read by Arthur Addison and made available from Books on Tape (1997). In 2011, Penguin Audiobooks produced a new unabridged recording of the book, read by Robertson Dean. In 2021, Audible released an unabridged recording, read by Jason Flemyng . Neuromancer
696-632: A PC for firmware updates; for example, a digital audio player might be updated to support a new file format . Some hobbyists have taken advantage of this flexibility to reprogram consumer products for new purposes; for example, the iPodLinux and OpenWrt projects have enabled users to run full-featured Linux distributions on their MP3 players and wireless routers, respectively. ROM is also useful for binary storage of cryptographic data, as it makes them difficult to replace, which may be desirable in order to enhance information security . Since ROM (at least in hard-wired mask form) cannot be modified, it
812-512: A bit line to a word line. Consequently, ROM could be implemented at a lower cost-per- bit than RAM for many years. Most home computers of the 1980s stored a BASIC interpreter or operating system in ROM as other forms of non-volatile storage such as magnetic disk drives were too costly. For example, the Commodore 64 included 64 KB of RAM and 20 KB of ROM containing a BASIC interpreter and
928-524: A company can simply order a large batch of fresh PROM chips and program them with the desired contents at its designers' convenience. The advent of the metal–oxide–semiconductor field-effect transistor (MOSFET), invented at Bell Labs in 1959, enabled the practical use of metal–oxide–semiconductor (MOS) transistors as memory cell storage elements in semiconductor memory , a function previously served by magnetic cores in computer memory . In 1967, Dawon Kahng and Simon Sze of Bell Labs proposed that
1044-399: A computer, each serving distinct roles. RAM, or Random Access Memory, is a temporary, volatile storage medium that loses data when the system powers down. In contrast, ROM, being non-volatile, preserves its data even after the computer is switched off. IBM used capacitor read-only storage (CROS) and transformer read-only storage (TROS) to store microcode for the smaller System/360 models,
1160-526: A copy of Case's consciousness, which now exists in cyberspace with those of Linda and Pauley. Neuromancer was released without fanfare, but it quickly became an underground word-of-mouth hit. Lawrence Person in his "Notes Toward a Postcyberpunk Manifesto" (1998) identified Neuromancer as "the archetypal cyberpunk work". In its record of award-wins, the novel legitimized cyberpunk as a mainstream branch of science fiction literature. Gibson commented on himself as an author circa Neuromancer that "I'd buy him
1276-597: A drink, but I don't know if I'd loan him any money," and referred to the novel as "an adolescent's book". Even so, the success of Neuromancer was to effect the 35-year-old Gibson's emergence from obscurity. Neuromancer became the first novel to win the Nebula , the Hugo , and Philip K. Dick Award for paperback original, an unprecedented achievement described by the Mail & Guardian as "the sci-fi writer's version of winning

Following the 17th-century development of the novel as a literary form , Mary Shelley 's Frankenstein (1818) and The Last Man (1826) helped define the form of the science fiction novel. Brian Aldiss has argued that Frankenstein was the first work of science fiction. Edgar Allan Poe wrote several stories considered to be science fiction, including " The Unparalleled Adventure of One Hans Pfaall " (1835), which featured

Wintermute/Neuromancer contacts him, claiming it has become "the sum total of the works, the whole show" and is looking for others like itself. Scanning recorded transmissions, the super-AI finds a transmission from the Alpha Centauri star system. While logged into cyberspace, Case glimpses Neuromancer standing in the distance with Linda Lee, and himself. He also hears inhuman laughter, which suggests that Pauley still lives. The sighting implies that Neuromancer created
2204-411: A new role as a medium for mass storage or secondary storage of files. Mask ROM is a read-only memory whose contents are programmed by the integrated circuit manufacturer (rather than by the user). The desired memory contents are furnished by the customer to the device manufacturer. The desired data is converted into a custom photomask /mask layer for the final metallization of interconnections on
2320-431: A powerful artificial intelligence . Before Neuromancer , Gibson had written several short stories for US science fiction periodicals—mostly noir countercultural narratives concerning low-life protagonists in near-future encounters with cyberspace . The themes he developed in this early short fiction, the Sprawl setting of " Burning Chrome " (1982), and the character of Molly Millions from " Johnny Mnemonic " (1981) laid

All of these technologies improved the flexibility of ROM, but at a significant cost-per-chip, so that in large quantities mask ROM would remain an economical choice for many years. (Decreasing cost of reprogrammable devices had almost eliminated the market for mask ROM by the year 2000.) Rewriteable technologies were envisioned as replacements for mask ROM. The most recent development

Some microcontrollers have mask ROM to store the bootloader or all of their firmware . Classic mask-programmed ROM chips are integrated circuits that physically encode the data to be stored, and thus it is impossible to change their contents after fabrication. It is also possible to write

However, the one-time masking cost is high and there is a long turn-around time from design to product phase. Design errors are costly: if an error in the data or code is found, the mask ROM is useless and must be replaced in order to change the code or data. As of 2003 , four companies produce most such mask ROM chips: Samsung Electronics , NEC Corporation , Oki Electric Industry , and Macronix . Some integrated circuits contain only mask ROM.

Because they are written by forcing electrons through a layer of electrical insulation onto a floating transistor gate , rewriteable ROMs can withstand only a limited number of write and erase cycles before the insulation is permanently damaged. In the earliest EPROMs, this might occur after as few as 1,000 write cycles, while in modern Flash EEPROM
8120-418: The endurance may exceed 1,000,000. The limited endurance, as well as the higher cost per bit, means that Flash-based storage is unlikely to completely supplant magnetic disk drives in the near future. The timespan over which a ROM remains accurately readable is not limited by write cycling. The data retention of EPROM, EAROM, EEPROM, and Flash may be time-limited by charge leaking from the floating gates of
8236-439: The episodes, ran from 1959 to 1964. It featured fantasy , suspense , and horror as well as science fiction, with each episode being a complete story. Critics have ranked it as one of the best TV programs of any genre . The animated series The Jetsons , while intended as comedy and only running for one season (1962–1963), predicted many inventions now in common use: flat-screen televisions , newspapers on
8352-768: The events the player went through. Psychologist and futurist Dr. Timothy Leary was involved, but very little documentation seems to exist about this proposed second game, which was perhaps too grand a vision for 1988 home computing. The BBC World Service Drama production of Neuromancer aired in two one-hour parts, on 8 and 15 September 2002. Dramatised by Mike Walker , and directed by Andy Jordan, it starred Owen McCarthy as Case, Nicola Walker as Molly, James Laurenson as Armitage, John Shrapnel as Wintermute, Colin Stinton as Dixie, David Webber as Maelcum, David Holt as Riviera, Peter Marinker as Ashpool, and Andrew Scott as The Finn. In Finland , Yle Radioteatteri produced
8468-762: The first science fiction novel . Some of the stories from The Arabian Nights , along with the 10th-century The Tale of the Bamboo Cutter and Ibn al-Nafis 's 13th-century Theologus Autodidactus , are also argued to contain elements of science fiction. Written during the Scientific Revolution and later the Age of Enlightenment are considered true science-fantasy books. Francis Bacon 's New Atlantis (1627), Johannes Kepler 's Somnium (1634), Athanasius Kircher 's Itinerarium extaticum (1656), Cyrano de Bergerac 's Comical History of
8584-674: The first two chapters, "Chiba City Blues" and "The Shopping Expedition", and was never continued. In the 1990s a version of Neuromancer was published as one of the Voyager Company 's Expanded Books series of hypertext-annotated HyperCard stacks for the Macintosh (especially the PowerBook ). A video game adaptation of the novel—also titled Neuromancer —was published in 1988 by Interplay . Designed by Bruce J. Balfour, Brian Fargo , Troy A. Miles, and Michael A. Stackpole ,
8700-721: The form of USB flash drives and tiny microSD memory cards , for example), and much lower power consumption. Many stored-program computers use a form of non-volatile storage (that is, storage that retains its data when power is removed) to store the initial program that runs when the computer is powered on or otherwise begins execution (a process known as bootstrapping , often abbreviated to " booting " or "booting up"). Likewise, every non-trivial computer needs some form of mutable memory to record changes in its state as it executes. Forms of read-only memory were employed as non-volatile storage for programs in most early stored-program computers, such as ENIAC after 1948 . (Until then it
8816-431: The form of erasable programmable read-only memory (EPROM), electrically erasable programmable read-only memory (EEPROM) and flash memory can be erased and re-programmed. But usually, this can only be done at relatively slow speeds, may require special equipment to achieve, and is typically only possible a certain number of times. The term "ROM" is sometimes used to refer to a ROM device containing specific software or
8932-407: The form of a young boy. Neuromancer tries to convince Case to remain in the virtual world with Linda, but Case refuses. With Wintermute guiding them, Case goes to confront Lady 3Jane, Riviera, and Hideo. Riviera tries to kill Case, but Lady 3Jane is sympathetic towards Case and Molly, and Hideo protects him. Riviera flees, and Molly explains that he is doomed anyway, as she had spiked his drugs with
9048-565: The foundations for the novel. John Carpenter 's Escape from New York (1981) influenced the novel; Gibson was "intrigued by the exchange in one of the opening scenes where the Warden says to Snake 'You flew the Gullfire over Leningrad ' [ sic ] It turns out to be just a throwaway line, but for a moment it worked like the best SF, where a casual reference can imply a lot." The novel's street and computer slang dialogue derives from
9164-475: The game had many of the same locations and themes as the novel, but a different protagonist and plot. It was available for a variety of platforms, including Amiga , Apple II , Commodore 64 , and MS-DOS -based IBM PC compatibles. According to an episode of the American version of Beyond 2000 , the original plans for the game included a dynamic soundtrack composed by Devo and a real-time 3D-rendered movie of
9280-486: The genre, it describes the history of humanity from the present onwards across two billion years. In 1937, John W. Campbell became editor of Astounding Science Fiction , an event that is sometimes considered the beginning of the Golden Age of Science Fiction , which was characterized by stories celebrating scientific achievement and progress . The "Golden Age" is often said to have ended in 1946, but sometimes
9396-420: The human system. Unthinkable complexity. Lines of light ranged in the nonspace of the mind, clusters and constellations of data. Like city lights, receding. The 1999 cyberpunk science fiction film The Matrix particularly draws from Neuromancer both eponym and usage of the term "matrix". "After watching The Matrix , Gibson commented that the way that the film's creators had drawn from existing cyberpunk works
9512-439: The impact of the cell phone ), "Imagining story, the inner workings of his characters' minds, and the world in which it all takes place are all more important." The novel has had significant linguistic influence, popularizing such terms as cyberspace and ICE ( Intrusion Countermeasures Electronics ). Gibson himself coined the term "cyberspace" in his novelette " Burning Chrome ", published in 1982 by Omni magazine, but it
9628-477: The implications of the Internet and the expanding information universe, questions about biotechnology , nanotechnology , and post-scarcity societies . Recent trends and subgenres include steampunk , biopunk , and mundane science fiction . The first, or at least one of the first, recorded science fiction film is 1902's A Trip to the Moon , directed by French filmmaker Georges Méliès . It
9744-442: The integrated circuit, although fuse re-growth was once a problem in some systems. The contents of ROM chips can be extracted with special hardware devices and relevant controlling software. This practice is common for, as a main example, reading the contents of older video game console cartridges . Another example is making backups of firmware/OS ROMs from older computers or other devices - for archival purposes, as in many cases,
9860-499: The invention of the integrated circuit came mask ROM . Mask ROM consists of a grid of word lines (the address input) and bit lines (the data output), selectively joined with transistor switches, and can represent an arbitrary look-up table with a regular physical layout and predictable propagation delay . Mask ROM is programmed with photomasks in photolithography during semiconductor manufacturing . The mask defines physical features or structures that will be removed, or added in
9976-415: The late 1940s and the 1950s are included. In 1942, Isaac Asimov started his Foundation series , which chronicles the rise and fall of galactic empires and introduced psychohistory . The series was later awarded a one-time Hugo Award for "Best All-Time Series". Theodore Sturgeon 's More Than Human (1953) explored possible future human evolution . In 1957, Andromeda: A Space-Age Tale by
10092-475: The memory cell transistors. Early generation EEPROM's, in the mid-1980s generally cited 5 or 6 year data retention. A review of EEPROM's offered in the year 2020 shows manufacturers citing 100 year data retention. Adverse environments will reduce the retention time (leakage is accelerated by high temperatures or radiation ). Masked ROM and fuse/antifuse PROM do not suffer from this effect, as their data retention depends on physical rather than electrical permanence of
10208-548: The memory chip (hence the name). Mask ROM can be made in several ways, all of which aim to change the electrical response of a transistor when it is addressed on a grid, such as: Mask ROM transistors can be arranged in either NOR or NAND configurations and can achieve one of the smallest cell sizes possible as each bit is represented by only one transistor. NAND offers higher storage density than NOR. OR configurations are also possible, but compared to NOR it only connects transistors to V cc instead of V ss . Mask ROMs used to be
10324-456: The modern genre primarily arose in the 19th and early 20th centuries when popular writers began looking to technological progress and speculation. Mary Shelley 's Frankenstein , written in 1818, is often credited as the first true science fiction novel . Jules Verne and H.G. Wells are pivotal figures in the genre's development. In the 20th century, expanded with the introduction of space operas , dystopian literature, pulp magazines , and
10440-417: The most inexpensive, and are the simplest semiconductor memory devices, with only one metal layer and one polysilicon layer, making it the type of semiconductor memory with the highest manufacturing yield (the highest number of working devices per manufacturing run). ROM can be made using one of several semiconductor device fabrication technologies such as CMOS , nMOS , pMOS , and bipolar transistors . It
10556-405: The movement of jumper plugs to apply write-enable signals, and special lock/unlock command codes. Modern NAND Flash can be used to achieve the highest write speeds of any rewritable ROM technology, with speeds as high as 10 GB / s in an SSD. This has been enabled by the increased investment in both consumer and enterprise solid-state drives and flash memory products for higher end mobile devices. On
10672-858: The need for a firmware upgrade arise. However, simple and mature sub-systems (such as the keyboard or some communication controllers in the integrated circuits on the main board, for example) may employ mask ROM or OTP (one-time programmable). ROM and successor technologies such as flash are prevalent in embedded systems . These are in everything from industrial robots to home appliances and consumer electronics ( MP3 players , set-top boxes , etc.) all of which are designed for specific functions, but are based on general-purpose microprocessors . With software usually tightly coupled to hardware, program changes are rarely needed in such devices (which typically lack hard disks for reasons of cost, size, or power consumption). As of 2008, most products use Flash rather than mask ROM, and many provide some means for connecting to
10788-427: The news that Seven Arts and GFM Films would be merging their distribution operations, it was announced that the joint venture would be purchasing the rights to Neuromancer under Vincenzo Natali's direction. In August 2012, GFM Films announced that it had begun casting for the film and made offers to Liam Neeson and Mark Wahlberg , but no cast members have been confirmed yet. In November 2013, Natali shed some light on
10904-478: The novellas included in the first novel, Dragonflight , made McCaffrey the first woman to win a Hugo or Nebula Award . In 1968, Philip K. Dick 's Do Androids Dream of Electric Sheep? was published. It is the literary source of the Blade Runner movie franchise . In 1969, The Left Hand of Darkness by Ursula K. Le Guin was set on a planet in which the inhabitants have no fixed gender . It
11020-459: The original chips are PROMs and thus at risk of exceeding their usable data lifetime. The resultant memory dump files are known as ROM images or abbreviated ROMs , and can be used to produce duplicate ROMs - for example to produce new cartridges or as digital files for playing in console emulators . The term ROM image originated when most console games were distributed on cartridges containing ROM chips, but achieved such widespread usage that it
11136-614: The play RUR , written by the Czech playwright Karel Čapek , broadcast live from the BBC's Alexandra Palace studios on 11 February 1938. The first popular science fiction program on American television was the children's adventure serial Captain Video and His Video Rangers , which ran from June 1949 to April 1955. The Twilight Zone (the original series), produced and narrated by Rod Serling , who also wrote or co-wrote most of
11252-457: The production situation; announcing that the script had been completed for "years", and had been written with assistance from Gibson himself. In May 2015, it was reported the movie got new funding from Chinese company C2M, but Natali was no longer available for directing. In August 2017, it was announced that Deadpool director Tim Miller was signed on to direct a new film adaptation by Fox, with Simon Kinberg producing. In November 2022, it
11368-468: The reaction of human beings to changes in science and technology ." Robert A. Heinlein wrote that "A handy short definition of almost all science fiction might read: realistic speculation about possible future events, based solidly on adequate knowledge of the real world, past and present, and on a thorough understanding of the nature and significance of the scientific method ." American science fiction author and editor Lester del Rey wrote, "Even
11484-443: The relative speed of RAM vs. ROM has varied over time, as of 2007 large RAM chips can be read faster than most ROMs. For this reason (and to allow uniform access), ROM content is sometimes copied to RAM or shadowed before its first use, and subsequently read from RAM. For those types of ROM that can be electrically modified, writing speed has traditionally been much slower than reading speed, and it may need unusually high voltage,
11600-670: The series gained popularity through syndication and extraordinary fan interest . It became a very popular and influential franchise with many films , television shows , novels , and other works and products. Star Trek: The Next Generation (1987–1994) led to six additional live action Star Trek shows: Deep Space Nine (1993–1999), Voyager (1995–2001) , Enterprise (2001–2005), Discovery (2017–2024), Picard (2020–2023), and Strange New Worlds (2022–present), with more in some form of development. Read-only memory Strictly speaking, read-only memory refers to hard-wired memory, such as diode matrix or
11716-515: The term speculative fiction to be used instead for those that are more "serious" or "thoughtful". Some scholars assert that science fiction had its beginnings in ancient times , when the line between myth and fact was blurred. Written in the 2nd century CE by the satirist Lucian , A True Story contains many themes and tropes characteristic of modern science fiction, including travel to other worlds, extraterrestrial lifeforms , interplanetary warfare, and artificial life . Some consider it
11832-454: The vocabulary of subcultures, particularly "1969 Toronto dope dealer's slang, or biker talk". Gibson heard the term " flatlining " in a bar around twenty years before writing Neuromancer and it stuck with him. Author Robert Stone , a "master of a certain kind of paranoid fiction", was a primary influence on the novel. The term "Screaming Fist" was taken from the song of the same name by Toronto-based punk rock band The Viletones . Neuromancer
11948-457: The whole time on the edge of my seat and got a cramp as a result. In a way Gibson's pace is too frenetic, so unremitting that the reader never gets a rest and can't see the plot for the dazzle. Otherwise: nice one." Langford also reviewed Neuromancer for White Dwarf #80, and stated that "You may not believe in killer programs which invade the brain, but Neuromancer , if you once let it into your wetware, isn't easily erased." In his afterward to
12064-499: The work has yet to be performed in full. There have been several proposed film adaptations of Neuromancer , with drafts of scripts written by British director Chris Cunningham and Chuck Russell , with Aphex Twin providing the soundtrack. The box packaging for the video game adaptation had even carried the promotional mention for a major motion picture to come from "Cabana Boy Productions." None of these projects have come to fruition, though Gibson had stated his belief that Cunningham
12180-523: Was 'exactly the kind of creative cultural osmosis" he had relied upon in his own writing. ' " Outside science fiction, the novel gained unprecedented critical and popular attention e.g., as an "evocation of life in the late 1980s", although The Observer noted that "it took the New York Times 10 years" to mention the novel. In 1989, Epic Comics published a 48-page graphic novel version by Tom de Haven and Bruce Jensen . It only covers
12296-456: Was a member of "Operation Screaming Fist," meant to disrupt Soviet computer systems. As his team attacked a Soviet computer center, EMP weapons shut down their flight systems. He and a few survivors escaped over the Finnish border, but their helicopter was shot down, killing everyone except for Corto. After months in a hospital, Corto was visited by a US government official, who returned him to
12412-618: Was announced in April 2024 to play Case. Briana Middleton joins the cast as Molly in June 2024. Science fiction Science fiction (sometimes shortened to SF or sci-fi ) is a genre of speculative fiction , which typically deals with imaginative and futuristic concepts such as advanced science and technology , space exploration , time travel , parallel universes , and extraterrestrial life . It often explores human responses to changes in science and technology. Science fiction
12528-575: Was cheap compared to RAM. Notably, the display adapters of early personal computers stored tables of bitmapped font characters in ROM. This usually meant that the text display font could not be changed interactively. This was the case for both the CGA and MDA adapters available with the IBM PC XT. The use of ROM to store such small amounts of data has disappeared almost completely in modern general-purpose computers. However, NAND Flash has taken over
12644-434: Was commissioned by Terry Carr for the second series of Ace Science Fiction Specials , which was intended to feature debut novels exclusively. Given a year to complete the work, Gibson undertook the actual writing out of "blind animal panic" at the obligation to write an entire novel—a feat which he felt he was "four or five years away from". After viewing the first 20 minutes of the landmark film Blade Runner (1982), which
12760-404: Was influential on later filmmakers , bringing a different kind of creativity and fantasy . Méliès's innovative editing and special effects techniques were widely imitated and became important elements of the cinematic medium . 1927's Metropolis , directed by Fritz Lang , is the first feature-length science fiction film. Though not well received in its time, it is now considered
12876-484: Was known for its embrace of a high degree of experimentation, both in form and in content, and a highbrow and self-consciously " literary " or " artistic " sensibility . In 1961, Solaris by Stanisław Lem was published in Poland . The novel dealt with the theme of human limitations as its characters attempted to study a seemingly intelligent ocean on a newly discovered planet . Lem's work anticipated
12992-408: Was not a stored-program computer as every program had to be manually wired into the machine, which could take days to weeks.) Read-only memory was simpler to implement since it needed only a mechanism to read stored values, and not to change them in-place, and thus could be implemented with very crude electromechanical devices (see historical examples below). With the advent of integrated circuits in
13108-406: Was released when Gibson had written a third of the novel, he "figured [ Neuromancer ] was sunk, done for. Everyone would assume I'd copied my visual texture from this astonishingly fine-looking film." He re-wrote the first two-thirds of the book 12 times, feared losing the reader's attention and was convinced that he would be "permanently shamed" following its publication; yet what resulted was seen as
13224-483: Was rumored that Apple TV+ was looking to begin work on a project to adapt Neuromancer into a TV series and were looking to cast Miles Teller in the lead role and with Graham Roland serving as writer, producer, and showrunner. In February 2024, Apple TV+ announced that it had greenlit the series—to be co-produced by Skydance Television , Anonymous Content , and DreamCrew Entertainment—for 10 episodes, with J. D. Dillard joining Roland as co-showrunner. Callum Turner
13340-408: Was the first of his three- decade -long planetary romance series of Barsoom novels , which were set on Mars and featured John Carter as the hero . These novels were predecessors to YA novels , and drew inspiration from European science fiction and American Western novels . In 1924, We by Russian writer Yevgeny Zamyatin , one of the first dystopian novels, was published. It describes
13456-542: Was through its use in Neuromancer that it gained recognition to become a synonym for the World Wide Web during the 1990s. The portion of Neuromancer usually cited in this respect is: The matrix has its roots in primitive arcade games. … Cyberspace. A consensual hallucination experienced daily by billions of legitimate operators, in every nation, by children being taught mathematical concepts. … A graphic representation of data abstracted from banks of every computer in
