A.B.Dick

Albert B. Dick developed a mimeograph machine combining his own ideas with those of Thomas Edison. Edison sold his interest in the machine to Albert Dick, with the agreement that the device would include Edison's name. The "Edison-Dick Mimeograph" was marketed in 1887. In 1904, a rotary mechanism was added which greatly increased the speed and versatility of the machine. Albert Dick's company later became well known as "A.B. Dick Company," (of Chicago) manufacturers of office equipment.

A.B. Dick also produced office automation equipment, including a variety of dedicated word processing microcomputers. Included among their many products was the A.B. Dick Magna SL, introduced in 1982, which sold for $14,500. The Magna was a multi-user system, probably one of the first such multi-user, dedicated word processing systems in the commercial arena.

In 1979, A.B. Dick was purchased by General Electric Company of the UK.

Aberdeen Proving Ground

Active Directory is a centralized system that automates network management of user data, security, and distributed resources, and enables interoperation with other directories. Active Directory is designed especially for distributed networking environments. It includes support for the Lightweight Directory Access Protocol (LDAP) to enable inter-directory operability

Active Server Page

An Active Server Page (ASP) is an HTML (Hypertext Markup Language) page that includes one or more small embedded programs (called "scripts") that are processed on a Microsoft Web server before the page is sent to the user. An ASP is somewhat similar to a Server-side include or a common gateway interface ("CGI") application. It can be used to customize a web page based on the user requested data. Related files have the .asp extension. (Source: Whatis.com)

Advanced Computing Environment.

Advanced Computing Environment. The ACE was formed in 1991 by a collection of vendors seeking to use the MIPS Computer Systems RISC (Reduced Instruction Set Computer) processing architecture or the 80X86 microprocessor technology from Intel and develop source code compatibility between SCO UNIX (Santa Cruz Operation) and System V release 4.0 of Unix, and other compatibilities.

Founding members included Digital Equipment Corporation, Compaq Computer, MIPS Computer Systems, SCO and Microsoft. The ACE effort did not meet its objectives and is no longer active.

Association for Computing Machinery (ACM) The ACM was formed on September 15, 1947 at Columbia University. It was originally known as the Eastern Association for Computing Machinery. The ACM has become the largest and one of the most important organizations in the field of information processing. The ACM publishes a variety of material including "The Journal of the Association for Computing Machinery," "Communications of the ACM," "Computing Reviews," and many others. The ACM created the Turing Award in 1961 for outstanding technical contributions to the computing field and established the Distinguished Service Award in 1970, recognizing special service in the field. The ACM has over 60,000 members (1995).

Acorn

Acorn was the code name given to the IBM PC during its early development. The development team was led by Philip Donald Estridge, and the first "IBM PCs" came off the product line in about July 1981.

Acoustic Delay Line

In the acoustic delay line storage device, an acoustic medium, such as mercury, is used to hold the sound pattern generated by a diaphragm device placed at each end of the medium or tank. The signals generated by the diaphragm echo or regenerate through the medium. The vibrations of the diaphragm correspond to binary bits.

Acoustic delay lines, or acoustic tanks could only store limited vibrations, so they were usually used in parallel. Delay line information was "read" by interrupting the echo regeneration of the sound wave at a specified time. Acoustic delay lines were used in some early computers of the 1950's.

Acrobat

Marc Andreesen and Tim Berners-Lee

Tim Berners-Lee, a researcher at CERN, a high-energy research laboratory on the French-Swish border, was the inventor of the World Wide Web concept and HTTP (Hypertext Transport Protocol), of the Internet. Berners-Lee invented the Web in 1989 by writing the first web server program and putting hypertext information online. The Web and HTTP made it possible for many more people to understand and use the Internet and were instrumental in the Internet's amazing growth since the early 1990's. Together with the development of the Web browser, Mosaic, by Marc Andreesen in 1993, these events sparked the user friendly Internet that we know today. Andreesen worked with his friend Eric Bina on the original 9000-lines of code that became Mosaic. Marc Andreesen also went on to co-found Netscape, which made the extremely popular Netscape Navigator web browser software. (Netscape was originally called "Electric Media," then "Mosaic Communications," and finally "Netscape." By 1996, 46 million copies of Netscape were in use worldwide. Netscape made its initial public offering (IPO) on August 9, 1995, and with stock opening at $28 per share, doubled and Netscape reached a value of $3 billion. (AOL purchased Netscape Communications in November of 1998.) (Ref: "Fire in the Valley: The Making of the Personal Computer," Paul Freiberger and Michael Swaine, McGraw-Hill, 2000.)

ANSI

American National Standards Institute. A standards organization consisting of various charter members, such as the Institute of Electrical and Electronics Engineers (IEEE) and the Electronic Industries Association (EIA), which help define and set standards in specific areas.

Anti-Trust Actions (U.S. Government)

IBM and U.S. Government

In 1912, the U.S. Government filed an anti-trust suit against National Cash Register(NCR). During the three month trial, several NCR executives were found at fault. This is the government's first use of the anti-trust laws in this fashion. In 1935, U.S. Government filed an anti-trust suit against IBM charging that IBM abused a dominant market position and engaged in anticompetitive tactics to maintain that position. In 1952, the U.S. Government filed another anti-trust action against IBM. In January 25, 1956, in the anti-trust case, United States of America vs. International Business Machines Corporation (Civil Action No 72-344, Southern District of New York, filed in 1952) was ended by a "Consent Decree." The thirty-seven page decree stated, among other things, that IBM would have to sell its equipment not exclusively lease it. On January 17, 1969, the United States Government filed an anti-trust lawsuit against IBM charging that IBM monopolized the general-purpose computer systems market. This suit lasted until January 8, 1982, at which time the Government withdrew it.

Microsoft Corporation and U.S. Government

In October 1997, the Justice Department filed a motion in Federal District Court, alleging that Microsoft had violated a 1994 consent decree dealing with certain aspects of licensing the Windows operating system to computer manufacturers. Specifically, the Justice Department asked the court to stop Microsoft from tying the use of its Windows 95 operating system to the use of its Internet browser, a tool to navigate the Internet.

On April 3, 2000, following a negative ruling by Judge Thomas Penfield Jackson, Microsoft said that it plans to request an expedited review by the U.S. Court of Appeals after the remedies phase and final decree. The appeal will stress a 1998 U.S. Court of Appeals decision that affirmed the company's right to support the Internet in the Windows operating system. (for more information see Microsoft online.

API

Application Programming Interface. A programming language interface between a software program, such as commercially available software applications, and the end user. APIs can provide "hooks" into programs and help provide compatibility.

By 1982, the video game industry was a $3 billion business. Atari's success attracted many competitors. The public's demand for the more simplistic video games dropped sharply, and profits fell. The years 1983 through 1985 were especially bad for video game vendors.

By 1984, Atari was deep into debt. Time Warner, Inc. sold Atari to Jack Tramiel and other investors. In May 1984, Tramiel created Atari Corporation, manufacturer and marketer of personal computers and video game systems.

In July, Atari Corporation acquired certain microcomputer and video game assets from the Atari, Inc. subsidiary of Warner Communications, Inc. Tramiel, formerly of Commodore Business Machines, focused Atari on creating a new personal computer.

In 1995, Atari obtained an agreement with WalMart to place its Jaguar home game systems in 400 of WalMart's superstores across the country. Atari failed to market the Jaguar effectively and sales were very poor. WalMart returned the remaining inventory to Atari, who was unable to meet financial obligations and decided to eventually sell off the company to JTS Corporation in July 1996.

Atari Home Computers

Atari also produced home computers which utilized a TV monitor. A wide variety of games were available for the Atari systems.

Atari 400

The Atari 400 home computer came with 16K of RAM and 10K of ROM. The model 400 used typewriter-style keyboard, with pressure-sensitive wipe-clean keyboard panel. It had 57 alphanumeric keys and four special function keys. It could support color, sound, inverse video, full-screen editing, and four-way cursor control. The Atari 400 used the 6502B microprocessor and had a .56 microsecond cycle and 1.8 MHz clock speed.

The 400 weighed just under 6 pounds and plugged into a television set for display. It was introduced in 1978. It cost about $500, later reduced to about $340 (1982).

Atari 800

The 800 used the 6502 processor, had 8K RAM expandable to 48K, and could access external cassette player or floppy drives. It was announced in 1978, although it did not ship until later. It weighed under 10 pounds and cost about $999.

Baudot, Emile

(origin of "baud rate") Emile Baudot was a French telegraph engineer who developed the multiplex telegraph system in 1874. The multiplex telegraph permitted multiple telegraph messages over a single line. The special code he developed for this purpose was called the "Baudot Code." Baudot code was a serial data transmission of binary digits ("0" and "1") which became extremely important in later digitial computing devices. The term "Baud Rate" is named after Baudot and refers to the number of changes in electrical state of a transmission line. Sometimes "Baud Rate" is used to describe modem speeds, however, BPS (bits per second) rate is a more accurate description of transmission speeds, and "Baud" is becoming less commonly used.

Tim Berners-Lee

Tim Berners-Lee, a researcher at CERN, a high-energy research laboratory on the French-Swish border, was the inventor of the World Wide Web concept and HTTP (Hypertext Transport Protocol), of the Internet. Berners-Lee invented the Web in 1989 by writing the first web server program and putting hypertext information online. The Web and HTTP made it possible for many more people to understand and use the Internet and were instrumental in the Internet's amazing growth since the early 1990's. Together with the development of the Web browser, Mosaic, by Marc Andreesen in 1993, these events sparked the user friendly Internet that we know today. Andreesen worked with his friend Eric Bina on the original 9000-lines of code that became Mosaic. Marc Andreesen also went on to co-found Netscape, which made the extremely popular Netscape Navigator web browser software. (Netscape was originally called "Electric Media," then "Mosaic Communications," and finally "Netscape." By 1996, 46 million copies of Netscape were in use worldwide. Netscape made its initial public offering (IPO) on August 9, 1995, and with stock opening at $28 per share, doubled and Netscape reached a value of $3 billion. (AOL purchased Netscape Communications in November of 1998.) (Ref: "Fire in the Valley: The Making of the Personal Computer," Paul Freiberger and Michael Swaine, McGraw-Hill, 2000.)

Bletchley Park

"Bletchley Park" is not a company or organization name, but refers to a location in the United Kingdom where extremely valuable wartime research was conducted in early computing and codebreaking. Bletchley Park is an estate situated between London and Birmingham, England. It was the sight of highly intense, highly secret intelligence work during World War II.

Activities at Bletchley Park were so secret, that details were not made public until 1975. Bletchley was referred to under a variety of code names, such as "BP," "War Station X," "Government Communications Headquarters (GCHQ)," and others. The focus of the work was project Ultra. Ultra was the code name for activities to decrypt high level enemy communications in the war.

The Germans had developed complex cipher codes and encryption methods, including a machine called the "Enigma."

The Enigma was a machine used to code messages based on a series of rotating wheels.

The German High Command intelligence service, called the Abwehr, used one version of Enigma, while the German military used a slightly different version. The two versions presented two different problems for the Bletchley Park team in breaking the Enigma codes. The Germans were using the Enigma machines during the 1930's. In the late 1930's, before the breakout of war, the British Government Code and Cipher School (GC&CS) moved from its location in London, to Bletchley Park. In 1939, there were only about 100 people located at Bletchley. By 1942, the Bletchley teams were capturing and reading some 4,000 German military signals per day.

Bletchley Park was essentially a British intelligence operation from its earliest days. In September 1943, a special agreement was signed that allowed the incorporation of certain U.S. members into the British Ultra project. By 1944, there were over 7,000 people there in various capacities and on various projects. The Bletchley Park location was probably chosen originally since it was not far from railways which ran north, south, east and west, and its proximity to a roadway to London (now the "A5").

The Bletchley estate of approximately 581 acres, was originally part of Etone Manor and later owned by Sir Herbert Samuel Leon, a London Stockbroker. The GC&CS obtained the property around 1938. During the war, many additional structures were added, called simply Huts (e.g., Hut 1, Hut 2, etc.) where many of the assigned personnel conducted their secret work.

One of the achievements of the Bletchley team was the creation of Colossus, a large, programmable electronic digital computer that was used to decrypt encoded German messages. The Colossus was used as early as February 1944, and nine improved versions of the machine were made over time.

Bletchley teams also designed machines called "Bombes" which were electromechanical code breaking devices used to discover the wheel settings for Enigma keys, and another machine called "the Baby," which was used to encipher key words to assist in the decryption of Enigma messages. The "Bombes" and the "Baby" devices were made by the British Tabulating Machine Company.

Among the many dedicated individuals who worked at Bletchley Park were Cambridge University mathematics professor Max M.A. Newman, Alan Turing (a major contributor to the development of the Bombe), C. E. Wynn-Williams (inventor of first electronic particle counter used in physics research), Allen W. M. Coombs (Ph.D., Glasgow University), D. W. Babbage, (descendent of Charles Babbage), Ian Fleming (intelligence expert and author of James Bond novels), Sidney Broadhurst, Lewis Powell (later to become Justice Powell of the Supreme Court), and Donald Michie, a codebreaker.

Bubble Memory

Bubble memory was developed in 1967 at Bell Laboratories by A. H. Bobeck. Bubble memory devices were constructed of garnet chips in which the data-storage "bubbles" are a few microns wide. Through photolithography, magnetic and conductive metal patterns are created on the chip. The metal patterns form the sensing elements. The information is stored in binary code, 1 or 0, corresponding to the presence or absence of a bubble. An advantage of bubble memory is that it retains information after the electrical current is turned off.

Burroughs formed the American Arithmometer Company in 1886. By 1895, they had built and sold 284 machines, by 1900, 1,500 machines and by 1903, 4,500 machines.

In 1905, the American Arithmometer Company changed its name to Burroughs.

In 1921, the Burroughs Adding Machine Company acquired Moon-Hopkins Billing Machine Company, a maker of billing and bookkeeping machines. By 1932, there were over 12,000 employees in the Burroughs company and the products were in use around the world.

In 1949, Burroughs Adding Machine Company established an electronics research laboratory in Philadelphia, Pennsylvania.

In 1953, Burroughs Adding Machine Company changed its name to Burroughs Corporation.

By 1966, Burroughs Corporation had revenues of $493,777,928, which was a 77% increase in net earnings from the previous year. In the 1960's Burroughs was the world's largest producer of accounting machines, which, along with its adding machines and calculators, amounted to nearly $300 million of its world-wide revenues. In addition to accounting machines, adding machines, calculators, cash registers, and magnetic ink document processing equipment, Burroughs also produced computers data processing forms and supplies, computers, space and defense systems, and electronic components.

Burroughs entered the computer field in the 1950's. In 1966, Burroughs added to its computer product line, including the new third generation, medium sized B2500 and B3500 models, and the large scale B6500 series. Over 90% of the machines were delivered to customers on a lease basis.

In 1980, Burroughs Corporation acquired the System Development Corporation, a leading manufacturer of information storage and retrieval equipment and data communications products. Also in 1980, Burroughs Corporation acquired Memorex, a leading supplier and systems integrator for the U.S. Government. In 1986, Burroughs merged with Sperry Corporation to form Unisys, the second largest computer company in the world. (See UNISYS)

Controversy over the Clipper Chip concept has been very widespread in the communications and networking field, as well as in other areas.

COBOL (Common Business Oriented Language)

By 1959, thousands of computers were in use in various business applications. Lack of standard business software was becoming a problem. On April 8, 1959, a meeting was held at the University of Pennsylvania Computing Center to set the format, agenda and list the proposed attendees for a formal meeting to discuss the issue of a common business language.

Present at the April meeting were I. Edward Block, Ben Cheydleur, Saul Gorn, Grace Hopper, Robert Rossheim, and Albert E. Smith. The meeting was held at the request of Mary K. Hawes of Burroughs Corporation's ElectroData Division. At this meeting, the group decided to ask the U.S. Department of Defense to sponsor the first formal meeting, which it did on May 28 and 29, 1959. About 40 individuals from government organizations, computer manufacturers and end users assembled, with Charles A. Phillips, Director of the Data Systems Research Staff, as Chair.

It was decided that three committees would be formed to deal with short-range, medium-range, and long-range objectives, under the direction of a Executive Committee. The long-range committee was never actually established. A Steering Committee was also formed to charter a course of action towards a common business language. They met on June 4, 1959 and decided to call themselves the Committee on Data Systems Languages (CODASYL). CODASYL established an Executive Committee to oversee the work of other committees.

The committees looked at several existing languages, including AIMACO, Comtran, FLOW-MATIC, Autocoder III, SURGE, Fortran, RCA 501 Assembler, Report Generator, and APG-1.

Computer, Evolution of the word "Computer"

 First known English language use of the word "computer" is found in writings of Sir Thomas Browne (1605-1682). Browne defined "computers" as persons who reckoned the passage of time through the making up of calendars. The word "Computer" comes from the Latin "Computare" to think, or count. The meaning of the word computer has evolved over the past 248 years. Here are some examples:

The 1881 edition of Stormonth's English Language Dictionary defines computer as:

------ "One who numbers, counts, reckons, or calculates."

The 1882 edition of the Hurst and Company dictionary, based on Websters, defines computer as:

------ "One who reckons or estimates."

Dictionaries after World War II began defining the word computer in terms of a machine as well as a person.

For example:

The 1961 edition of Webster's Collegiate Dictionary defines computer as:

------ "One who computes; an automatic electronic machine for performing calculations."

Although some dictionaries still carry both definitions, by the 1980's, the term computer is quite often defined as a device only, with little or no reference to its older definition.

For example:

The 1980 Oxford American Dictionary defines computer simply as:

------ "An electronic machine for making calculations, storing and analyzing information fed into it, and controlling machinery automatically."

CP/M (Control Program for Microprocessors) (CPM)

CP/M was an operating system for microcomputers developed in 1973 by Dr. Gary Kildall, a brilliant software engineer. In 1976, Dr. Kildall started selling CP/M for $75 a copy through "Dr. Dobb's Journal" (published by Jim Warren), and it sold well.

Dr. Kildall and his wife founded Digital Research (1976) and sales of CP/M continued to increase. By the end of the 1970's, Digital Research had over 900 different firms as clients. CP/M became the standard operating program for microcomputers in the early 1980's. By the mid 1980's, CP/M was running on over 300 different models of microcomputers.

When IBM planned to introduce its personal computer, they had some initial talks with Digital Research regarding CP/M. As it turned out, however, IBM entered into an agreement with Microsoft and the IBM PC came out in 1981 with PC DOS as its operating system. DOS gradually took the lead over CP/M, and became pretty much the standard by the end of the 1980's. DOS was actually modeled after CP/M.

It was estimated by Kildall that by 1987, there were over 200 million copies of CP/M in existence,and over 3,000 programs available for CP/M machines, many of them still in use today.

Cray Research Company

Cray Research Company was formed in 1972 by the brilliant computer scientist and supercomputing pioneer Seymour Cray, after Cray left Control Data Corporation (CDC). Cray Research built some of the worlds largest and fastest supercomputers.

A Brief Chronology of some of the computers developed by Cray Research.

1976

The CRAY-1 supercomputer was a built as a prototype by Cray Research. The CRAY-1 contained 200,000 integrated circuits and could perform 100 million floating point operations per second (100 MFLOPS). The CRAY-1 was delivered to the Los Alamos National Laboratory.

1985

In June, Cray Research announced the CRAY-2 supercomputer. The CRAY-2 Supercomputer had four processors (twice as many as the CRAY X-MP). The CRAY-2 had six miles of wire and required a liquid Freon-like coolant to keep it from overheating. The liquid coolant unit produced a foam and caused some to refer to the Cray-2 as "Bubbles." The first full sized CRAY-2 supercomputer is delivered to NASA's Ames facility in October. Approximate cost of the CRAY was$17 million dollars.

1987

Cray introduced the CRAY-2S which was 40% faster than the CRAY-2.

1988

In February, Cray Research announced the CRAY Y-MP, its most powerful supercomputer.

1988

In May, the CRAY X-MP EA Supercomputer was announced.

1989

Cray Research spun off Cray Computer Corporation (CCC), with Seymour Cray as the chief executive. (Cray Computer Corporation worked on the CRAY-3 Super Scalable System and the CRAY-4 supercomputer. It ran into financial difficulties and filed for bankruptcy in March 1995.)

1990

Cray Research acquired SuperTek Computers, makers of lower- priced Cray-compatible supercomputers.

1991

Cray Research acquires Floating Point Systems and made it a subsidiary business called Cray Research Superservers.

1992

Cybernetics

(definition) Cybernetics is the science of signals for the direction and control of living organisms, machines and certain groups of people. The term cybernetics comes from the Greek root word meaning the art of steering.

The term cybernetics, referring to a field of study, was probably first used by A. M. Ampere, a French scientist, in 1843. The field of cybernetics did not become developed until the 1940's.

In 1948, mathematics professor Norbert Wiener of Columbia University published a book entitled "Cybernetics or control signals in living organisms or machines."

In general, cybernetics deals with control in both living organisms and machines.

The dedicated machines faded from popular use when more flexible, more affordable personal computers came into more widespread use in the early 1980's.

De Forest, Lee (1873-1961)

De Forest, an American, was a graduate of Yale University and is often called the "Father of Radio." De Forest was an inventor who achieved over 300 patents during his lifetime. His most notable invention was the "Audion," which was a forerunner of later radio and television tubes. De Forest worked tirelessly in the area of wireless telegraphy. In 1902, he set up the De Forest Wireless Telegraphy Company. Bad management caused the company to crash in 1911.

De Forest made and lost several fortunes during his life, but continued working and inventing. He also developed a process called "phonofilm" which allowed a sound track to be photographed on the same film as a motion picture.

However, the "talking pictures" concept was too early for producers to take an active interest in it. De Forest's work on the Audion, and later improvements on it by such companies as AT&T,Westinghouse and others, was a major milestone in the development of the electronics industry.
