This document provides information about computers and their history. It defines key computer components like the central processing unit, monitor, keyboard, mouse, and printer. It also lists 10 important figures in the development of the computer, including Charles Babbage, Alan Turing, John von Neumann, Douglas Engelbart, and Vinton Cerf. Finally, it gives a brief overview of the early history of computers from Babbage's Analytical Engine to the invention of the integrated circuit.

COMPUTER MEANING A computer is a device that can be instructed to carry out sequences of arithmetic or logical operations automatically via computer programming. Modern computers have the ability to follow generalized sets of operations, called programs. These programs enable computers to perform an extremely wide range of tasks.
DEFINITIONS A computer monitor is an output device which displays information in pictorial form. A monitor usually comprises the display device, circuitry, casing, and power supply. A central processing unit (CPU) is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions. Computer speakers, or multimedia speakers, are speakers sold for use with computers, although usually capable of other audio uses, e.g. for an MP3 player. Most such speakers have an internal amplifier and consequently require a power source, which may be by a mains power supply often via an AC adapter, batteries, or a USB port (able to supply no more than 2.5W DC, 500mA at 5V). A computer mouse is a hand-held pointing device that detects two-dimensional motion relative to a surface. This motion is typically translated into the motion of a pointer on a display, which allows a smooth control of the graphical user interface.
DEFINITION In computing, a computer keyboard is a typewriter-style device[1] which uses an arrangement of buttons or keys to act as mechanical levers or electronic switches. Following the decline of punch cards and paper tape, interaction via tele printer- style keyboards became the main input method for computers. In computing, a printer is a peripheral device which makes a persistent human- readable representation of graphics or text on paper.[1] The first computer printer designed was a mechanically driven apparatus by Charles Babbage for his difference engine in the 19th century; however, his mechanical printer design was not built until 2000.[2] The first electronic printer was the EP-101, invented by Japanese company Epson and released in 1968.[3][4]

A BRIEF COMPUTER HISTORY Brief History Of Computer. The computer as we know it today had its beginning with a 19th century English mathematics professor name Charles Babbage. He designed the Analytical Engine and it was this design that the basic framework of the computers of today are based on. ... It was called the Atanasoff - Berry Computer (ABC) ...
TOP 10 MEN BEHIND COMPUTER 1.Charles Babbage Died at 80 (1791-1871) Father of Computing. 2.Claude Shannon Died at 85 (1916-2001) Wrote a paper in '37 that showed that electrical application of Boolean algebra could be used for computation (digital calculation). 3.Alan Mathison Turing OBE FRS (/tjr肘/; 23 June 1912 7 June 1954) was an English computer scientist, mathematician, logician, cryptanalyst, philosopher, and theoretical biologist.[2]
4.John von Neumann (/vn n肘mn/; Hungarian: Neumann J叩nos Lajos, pronounced [njmn jano ljo]; December 28, 1903 February 8, 1957) was a Hungarian-American mathematician, physicist, computer scientist, and polymath. 5.William Bradford Shockley Jr. (February 13, 1910 August 12, 1989) was an American physicist and inventor. Shockley was the manager of a research group at Bell Labs that included John Bardeen and Walter Brattain.
6.Douglas Carl Engelbart (January 30, 1925 July 2, 2013) was an American engineer and inventor, and an early computer and Internet pioneer. He is best known for his work on founding the field of humancomputer interaction, particularly while at his Augmentation Research Center Lab in SRI International, which resulted in creation of the computer mouse, and the development of hypertext, networked computers, and precursors to graphical user interfaces. 7.Robert Norton Noyce (December 12, 1927 June 3, 1990), nicknamed "the Mayor of Silicon Valley," was an American physicist who co-founded Fairchild Semiconductor in 1957 and Intel Corporation in 1968. He is also credited (along with Jack Kilby ) with the realization of the first integrated circuit or microchip that fueled the personal computer revolution and gave Silicon Valley its name.[1][nb 1]
8.Stephen Gary Wozniak (/wzni脱k/; born on August 11, 1950),[1]:18[9] often referred to by the nickname Woz,[10][11] is an American inventor, electronics engineer, programmer, philanthropist, and technology entrepreneur who co- founded Apple, Inc.. He and Apple co-founder Steve Jobs are widely recognized as pioneers of the personal computer revolution of the 1970s and 1980s. 9.Grace Brewster Murray Hopper (n辿e Murray; December 9, 1906 January 1, 1992) was an American computer scientist and United States Navy rear admiral.[1] One of the first programmers of the Harvard Mark I computer, she was a pioneer of computer programming who invented one of the first compiler related tools.
10.Vinton Gray Cerf[2] ForMemRS,[1] (/srf/; born June 23, 1943) is an American Internet pioneer, who is recognized as one of[7] "the fathers of the Internet",[8] sharing this title with TCP/IP co-inventor Bob Kahn.[9][10] His contributions have been acknowledged and lauded, repeatedly, with honorary degrees and awards that include the National Medal of Technology,[2]the Turing Award,[11] the Presidential Medal of Freedom,[12] the Marconi Prize and membership in the National Academy of Engineering.
