The term “computer” comes from Latin word “computare” which suggests to calculate.

A computer could be a programmable device that accepts data as input and processes it with set of directions to supply result as output. It renders output simply once activity mathematical and logical operations. The device additionally has a memory that stores the info, programs and results of process.

It is believed that Analytical Engine was the primary pc. it absolutely was fabricated by Charles Babbage in 1837. Charles Babbage is additionally thought of because the father of pc.

On the premise of information handling capabilities, the Computer is of 3 types:

 

History Of Computer

One of the earliest machines designed to help folks in calculations was the abacus that continues to be being employed some 5000 years when its invention.
In 1642 mathematician (a famed French mathematician) fictional associate totaliser supported mechanical gears during which numbers were diagrammatical by the cogs on the wheels.
Englishman, Charles Babbage, fictional within the 1830’s a “Difference Engine” created out of brass and alloy rods and gears, associated conjointly designed an additional device that he referred to as an “Analytical Engine”. His style contained the 5 key characteristics of recent computers:-
An device
Storage for numbers waiting to be processed
A processor or variety calculator
A unit to regulate the task and therefore the sequence of its calculations
An output device
Augusta ADA Lord George Gordon Byron (later noblewoman of Lovelace) was associate associate of Babbage United Nations agency has become referred to as the primary computer user.
An yank, inventor, developed (around 1890) the primary electrically driven device. It utilized punched cards associated metal rods that knowledgeable the holes to shut an electric circuit and so cause a counter to advance. This machine was ready to complete the calculation of the 1890 U.S. census in half-dozen weeks compared with seven 1/2 years for the 1880 census that was manually counted.
In 1936 Howard Conrad Potter Aiken of Harvard University convinced Thomas Watson of IBM to take a position $1 million within the development of associate mechanical device version of Babbage’s analytical engine. The Harvard Mark one was completed in 1944 and was eight feet high and fifty five feet long.
At regarding a similar time (the late 1930’s) John Atanasoff of Iowa State University and his assistant Clifford Berry engineered the primary computing device that worked electronically, the bedrock (Atanasoff-Berry Computer). This machine was primarily atiny low calculator.
In 1943, as a part of British war effort, a series of thermionic vacuum tube based mostly computers (named Colossus) were developed to crack German secret codes. The Colossus Mark two series (pictured) consisted of 2400 vacuum tubes.
John Mauchly and J. Presper Eckert of the University of Pennsylvania developed these ideas more by proposing a large machine consisting of eighteen,000 vacuum tubes. ENIAC (Electronic Numerical planimeter And Computer) was born in 1946. it absolutely was a large machine with a large power demand and 2 major disadvantages. Maintenance was extraordinarily troublesome because the tubes stone-broke down often and had to get replaced, and conjointly there was an enormous drawback with heating. the foremost necessary limitation, however, was that each time a brand new task required to be performed the machine ought to be rewired. In alternative words programming was administered with a hand tool.
In the late 1940’s John John von Neumann (at the time a special advisor to the ENIAC team) developed the EDVAC (Electronic separate Variable Automatic Computer) that pioneered the “stored program concept”. This allowed programs to be scan into the pc and then gave birth to the age of general computers.
