There is no easy answer to this question due to the many different classifications of computers. The first mechanical computer, created by Charles Babbage in 1822, doesn't resemble what most would consider a computer today. Therefore, this page lists each of the computer firsts, starting with the Difference Engine and leading up to the computers we use today.

Early inventions that lead up to the computer, such as the abacus, astrolabe, slide rule, clocks, calculator, and tablet machines, are not accounted for on this page.

When was the word "computer" first used?

The word "computer" was first used in 1613 in the book The Yong Mans Gleanings by Richard Braithwaite and originally described a human who performed calculations or computations. The definition of a computer remained the same until the end of the 19th century, when the industrial revolution gave rise to mechanical machines whose primary purpose was calculating.

First mechanical computer or automatic computing engine concept

In 1822, Charles Babbage conceptualized and began developing the Difference Engine, the first automatic computing machine to approximate polynomials. The Difference Engine could compute several sets of numbers and make hard copies of the results. Babbage received some help with developing the Difference Engine from Ada Lovelace, who was considered the first computer programmer for her work. Unfortunately, because of funding, Babbage could never complete a full-scale functional version of this machine. In June 1991, the London Science Museum completed the Difference Engine No. 2 for the bicentennial year of Babbage's birth and later completed the printing mechanism in 2000.

First general-purpose computer

In 1837, Charles Babbage proposed the first general mechanical computer, the Analytical Engine. The Analytical Engine contained an ALU ( arithmetic logic unit), basic flow control, punch cards (inspired by the Jacquard Loom), and integrated memory. It is the first general-purpose computer concept that could be used for many things, not only one particular computation. Unfortunately, because of funding issues, this computer was never built while Charles Babbage was alive. In 1910, Henry Babbage, Charles Babbage's youngest son, completed a portion of this machine and performed basic calculations.

The first machine to record and store information

In 1890, Herman 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, saving the census office millions of dollars. Hollerith would later form the company we know today as IBM.

First programmable computer

The was created by German Konrad Zuse in his parents' living room between 1936 and 1938. It is the first electromechanical binary programmable computer and the first functional modern computer.

Konrad Zuse would also later create 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 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 began development by Professor John Vincent Atanasoff and graduate student Cliff Berry in 1937. Its development continued until 1942 at 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 (central processing unit) (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 (Electronic Numerical Integrator and Computer) 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, used about 18,000 vacuum tubes, and weighed 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 (Electronic Delay Storage Automatic Calculator), 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 (Eckert-Mauchly Computer Corporation) and released several mainframe computers under the UNIVAC (Universal Automatic Computer) 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, the first commercial computer. The computer was sold to Eduard Stiefel, a mathematician at the Swiss Federal Institute of Technology Zurich, on July 12, 1950.

IBM's first computer

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

The first computer with RAM

MIT (Massachusetts Institute of Technology) introduced the Whirlwind machine on March 8, 1955, a revolutionary computer that was the first digital computer with magnetic core RAM (random-access memory) and real-time graphics.

The first transistor computer

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

The first minicomputer

In 1960, Digital Equipment Corporation released its first of many PDP (Programmed Data Processor) computers, the PDP-1.

The first desktop and mass-market computer

In 1964, the first desktop computer, the Programma 101, was unveiled 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 1968, Hewlett Packard began marketing the HP 9100A, the first mass-marketed desktop computer.

The first workstation

Although it was never sold, the first workstation is considered to be the , introduced in 1974. The computer was revolutionary for its time and included a fully functional computer, display, and mouse. The computer operated like many GUI (graphical user interface) computers today, utilizing windows, menus, 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 introduced the first microprocessor, the , 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 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. However, the first personal computer is considered by many to be the KENBAK-1, which was 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 was the first portable computer, released in September 1975. The computer weighed 55-pounds and had a five-inch CRT (cathode ray tube) display, tape drive, 1.9 MHz PALM processor, and 64 KB of RAM. The picture is an ad for 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) 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 (compact disc read-only memory).

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 supply, display, keyboard, 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 and 16 KB of memory, which was expandable to 256 and used MS-DOS.

The first PC clone

The Compaq Portable is considered the first PC clone and was released in March 1983 by Compaq. The Compaq Portable was 100% compatible with IBM computers and could run any software developed for IBM computers.

See our index of computer companies for information about manufacturers of IBM-compatible computers.

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