FIRST IN HISTORY OF COMPUTER
First mechanical computer
In 1822, Charles Babbage conceptualized and began developing the Difference Engine, which is considered the first automatic computing machine.
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.
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 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.
First concepts (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 first electric
programmable computer
The Colossus was the first electric programmable computer, developed by Tommy Flowers, and was first demonstrated in December 1943.
The first digital
computer
The ABC (Atanasoff-Berry
Computer) 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 ENIAC was invented by J.
Presper Eckert and John Mauchly at the University of Pennsylvania. 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,
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.
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.
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 a series of 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, 1953, IBM 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 1960, Digital 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.
In 1968, Hewlett 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 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 first laptop or
portable computer
The IBM 5100 is the first portable
computer, which was released in September 1975.
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 IBM PCD (PC Division) later
released the IBM portable in 1984, its first portable computer that weighed
30-pounds.
The first Apple computer
The Apple I (Apple 1) was the first
Apple computer that initially sold for $666.66.
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 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.
