COMPUTER INVENTIONS

COMPUTER INVENTIONS

COMPUTER INVENTIONS:-An invention is a new thing that someone has made. The computer was an invention when it was first made. We say when it was “invented”. New things that are made or created are called inventions.

What is the difference between computer inventions and computer discovery?

A discovery is recognizing something that already exists for the first time, that nobody has found before, e.g., how Christopher Columbus discovered the Americas. An invention is creating something totally new with one’s own ideas and development.

What is the difference between Computer innovation and Computer inventions?

To invent something is to discover a new thing. Meanwhile, to innovate means ​“to use a new​idea or​method”. To innovate is to introduce something new to the market, to manipulate existing inventions and turn them into a product or process that is of use in the real world.

computer is a digital electronic machine that can be programmed to carry out sequences of arithmetic or logical operations (computation) automatically.

English mathematician and inventor Charles Babbage is credited with having conceived the first automatic digital computer. During the mid-1830s Babbage developed plans for the Analytical Engine. Although it was never completed, the Analytical Engine would have had most of the basic elements of the present-day computer.

In 1812 Babbage helped found the Analytical Society, whose object was to introduce developments from the European continent into English mathematics. In 1816 he was elected a fellow of the Royal Society of London. He was instrumental in founding the Royal Astronomical (1820) and Statistical (1834) societies.

The idea of mechanically calculating mathematical tables first came to Babbage in 1812 or 1813. Later he made a small calculator that could perform certain mathematical computations to eight decimals. Then in 1823 he obtained government support for the design of a projected machine, the Difference Engine, with a 20-decimal capacity. The Difference Engine was a digital device: it operated on discrete digits rather than smooth quantities, and the digits were decimal (0–9), represented by positions on toothed wheels rather than binary digits (“bits”). When one of the toothed wheels turned from nine to zero, it caused the next wheel to advance one position, carrying the digit. Like modern computers, the Difference Engine had storage—that is, a place where data could be held temporarily for later processing. Its construction required the development of mechanical engineering techniques, to which Babbage of necessity devoted himself. In the meantime (1828–39), he served as Lucasian Professor of Mathematics at the University of Cambridge. However, the full engine, designed to be room-sized, was never built, at least not by Babbage. All design and construction ceased in 1833, when Joseph Clement, the machinist responsible for actually building the machine, refused to continue unless he was prepaid.

During the mid-1830s Babbage developed plans for the Analytical Engine, the forerunner of the modern digital computer. In that device he envisioned the capability of performing any arithmetical operation on the basis of instructions from punched cards, a memory unit in which to store numbers, sequential control, and most of the other basic elements of the present-day computer. As with the Difference Engine, the project was far more complex than anything theretofore built. The memory unit was to be large enough to hold 1,000 50-digit numbers; this was larger than the storage capacity of any computer built before 1960. The machine was to be steam-driven and run by one attendant.

In 1843 Babbage’s friend mathematician Ada Lovelace translated a French paper about the Analytical Engine and, in her own annotations, published how it could perform a sequence of calculations, the first computer program. The Analytical Engine, however, was never completed. Babbage’s design was forgotten until his unpublished notebooks were discovered in 1937. In 1991 British scientists-built Difference Engine No. 2—accurate to 31 digits—to Babbage’s specifications, and in 2000 the printer for the Difference Engine was also built.

Babbage made notable contributions in other areas as well. He assisted in establishing the modern postal system in England and compiled the first reliable actuarial tables. He also invented a type of speedometer and the locomotive cowcatcher.

The ENIAC was invented by J. Presper Eckert and John Mauchly at the University of Pennsylvania and began construction in 1943 and was not completed until 1946. It occupied about 1,800 square feet and used about 18,000 vacuum tubes, weighing almost 50 tons.

First general-purpose computer

In 1837Charles Babbage proposed the first general mechanical computer, the Analytical Engine. The Analytical Engine contained an ALU (Arithmetic Logic Unit), basic flow controlpunch cards (inspired by the Jacquard Loom), and integrated memory. It is the first general-purpose computer concept that could be used for many things and not only one particular computation. Unfortunately, because of funding issues, this computer was also never built while Charles Babbage was alive. In 1910, Henry Babbage, Charles Babbage’s youngest son, was able to complete a portion of this machine and perform basic calculations.

The first machine to record and store information

In 1890Herman Hollerith developed a method for machines to record and store information on punch cards for the US census. Hollerith’s machine was approximately ten times faster than manual tabulations and saved the census office millions of dollars. Hollerith would later form the company we know today as IBM.

First programmable computer

The Z1 was created by German Konrad Zuse in his parents’ living room between 1936 and 1938. It is considered to be the first electromechanical binary programmable computer and the first functional modern computer. Konrad Zuse would also later created the Z3, the first functioning programmable computer that could be fully automated.

First concepts of what we consider a modern computer

The Turing machine was first proposed by Alan Turing in 1936 and became the foundation for theories about computing and computers. The machine was a device that printed symbols on paper tape in a manner that emulated a person following several logical instructions. Without these fundamentals, we wouldn’t have the computers we use today.

The first electric programmable computer

The Colossus was the first electric programmable computer, developed by Tommy Flowers, and was first demonstrated in December 1943. The Colossus was created to help the British code breakers read encrypted German messages.

The first digital computer

Short for Atanasoff-Berry Computer, the ABC began development by Professor John Vincent Atanasoff and graduate student Cliff Berry in 1937. Its development continued until 1942 at the Iowa State College (now Iowa State University).

The ABC was an electrical computer that used more than 300 vacuum tubes for digital computation, including binary math and Boolean logic, and had no CPU (was not programmable). On October 19, 1973, US Federal Judge Earl R. Larson signed his decision that the ENIAC patent by J. Presper Eckert and John Mauchly was invalid. In the decision, Larson named Atanasoff the sole inventor.

The ENIAC was invented by J. Presper Eckert and John Mauchly at the University of Pennsylvania and began construction in 1943 and was not completed until 1946. It occupied about 1,800 square feet and used about 18,000 vacuum tubes, weighing almost 50 tons. Although a judge later ruled the ABC computer was the first digital computer, many still consider the ENIAC to be the first digital computer because it was fully functional.

The first stored program computer

The first computer to electronically store and execute a program was the SSEM (Small-Scale Experimental Machine), also known as the “Baby” or “Manchester Baby,” in 1948. It was designed by Frederic Williams, and built by his protégée, Tom Kilburn, with the assistance of Geoff Tootill, at the University of Manchester, England. Kilburn wrote the first electronically-stored program, which finds the highest proper factor of an integer, using repeated subtraction rather than division. Kilburn’s program was executed on June 21, 1948.

The second stored-program computer was also British: the EDSAC, built and designed by Maurice Wilkes at the University of Cambridge Mathematical Laboratory in England. The EDSAC performed its first calculation on May 6, 1949. It was also the first computer to run a graphical computer game, “OXO,” an implementation of tic-tac-toe displayed on a 6-inch cathode ray tube.

Around the same time, the Manchester Mark 1 was another computer that could run stored programs. Built at the Victoria University of Manchester, the first version of the Mark 1 computer became operational in April 1949. Mark 1 was used to run a program to search for Mersenne primes for nine hours without error on June 16 and 17 that same year.

The first computer company

The first computer company was Electronic Controls Company and was founded in 1949 by J. Presper Eckert and John Mauchly, the same individuals who helped create the ENIAC computer. The company was later renamed to EMCC or Eckert-Mauchly Computer Corporation and released several mainframe computers under the UNIVAC name.

First computer with a program stored in memory

First delivered to the United States government in 1950, the UNIVAC 1101 or ERA 1101 is considered the first computer capable of storing and running a program from memory.

First commercial computer

In 1942, Konrad Zuse began working on the Z4 that later became the first commercial computer. The computer was sold to Eduard Stiefel, a mathematician of the Swiss Federal Institute of Technology Zurich, on July 12, 1950.

IBM’s first computer

On April 7, 1953IBM publicly introduced the 701, its first commercial scientific computer.

The first computer with RAM

MIT introduces the Whirlwind machine on March 8, 1955, a revolutionary computer that was the first digital computer with magnetic core RAM and real-time graphics.

The first transistor computer

The TX-0 (Transistorized Experimental computer) is the first transistorized computer to be demonstrated at the Massachusetts Institute of Technology in 1956.

The first minicomputer

In 1960Digital Equipment Corporation released its first of many PDP computers, the PDP-1.

The first desktop and mass-market computer

In 1964, the first desktop computer, the Programma 101, was unveiled to the public at the New York World’s Fair. It was invented by Pier Giorgio Perotto and manufactured by Olivetti. About 44,000 Programma 101 computers were sold, each with a price tag of $3,200.

In 1968Hewlett Packard began marketing the HP 9100A, considered to be the first mass-marketed desktop computer.

The first workstation

Although it was never sold, the first workstation is considered to be the Xerox Alto, introduced in 1974. The computer was revolutionary for its time and included a fully functional computer, display, and mouse. The computer operated like many computers today utilizing windowsmenus, and icons as an interface to its operating system. Many of the computer’s capabilities were first demonstrated in The Mother of All Demos by Douglas Engelbart on December 9, 1968.

The first microprocessor

Intel introduces the first microprocessor, the Intel 4004, on November 15, 1971.

The first microcomputer

The Vietnamese-French engineer André Truong Trong Thi and Francois Gernelle developed the Micral computer in 1973. Considered as the first microcomputer, it used the Intel 8008 processor and was the first commercial non-assembly computer. It originally sold for $1,750.

The first personal computer (PC)

In 1975, Ed Roberts coined the term “personal computer” when he introduced the Altair 8800. Although the first personal computer is considered by many to be the KENBAK-1, which was first introduced for $750 in 1971. The computer relied on several switches for inputting data and output data by turning on and off several lights.

The first laptop or portable computer

The IBM 5100 is the first portable computer, which was released in September 1975. The computer weighed 55-pounds and had a five-inch CRT display, tape drive, 1.9 MHz PALM processor, and 64 KB of RAM. In the picture is an ad of the IBM 5100 taken from a November 1975 issue of Scientific American.

The first truly portable computer or laptop is considered to be the Osborne I, which was released in April 1981 and developed by Adam Osborne. The Osborne I weighed 24.5-pounds, had a 5-inch display, 64 KB of memory, two 5 1/4″ floppy drives, ran the CP/M 2.2 operating system, included a modem, and cost $1,795.

The IBM PCD (PC Division) later released the IBM portable in 1984, its first portable computer that weighed 30-pounds. Later in 1986, IBM PCD announced its first laptop computer, the PC Convertible, weighing 12-pounds. Finally, in 1994, IBM introduced the IBM ThinkPad 775CD, the first notebook with an integrated CD-ROM.

The first Apple computer

The Apple I (Apple 1) was the first Apple computer that initially sold for $666.66. The computer kit was developed by Steve Wozniak in 1976 and contained a 6502 8-bit processor and 4 kb of memory, which was expandable to 8 or 48 kb using expansion cards. Although the Apple I had a fully assembled circuit board, the kit required a power supplydisplaykeyboard, and case to be operational. Below is a picture of an Apple I from an advertisement by Apple.

The first IBM personal computer

IBM introduced its first personal computer, the IBM PC, in 1981. The computer was code-named Acorn. It featured an 8088 processor, 16 KB of memory, which was expandable to 256 and used MS-DOS.

The first PC clone

The Compaq Portable is considered to be the first PC clone and was released in March 1983 by Compaq. The Compaq Portable was 100% compatible with IBM computers and was capable of running any software developed for IBM computers.

The first multimedia computer

In 1992, Tandy Radio Shack released the M2500 XL/2 and M4020 SX, among the first computers to feature the MPC standard.
