Charles Babbage and the mechanical computer Before Babbage, computers were humans.
Credit: Science Museum Far from being discouraged by this setback, mathematician, philosopher, engineer and inventor Charles Babbage doubled down. The Thomson brothers and analogue computers In , one year after Charles Babbage died, the great physicist William Thomson Lord Kelvin invented a machine capable of performing complex calculations and predicting the tides in a given place.

Turing and the universal computing machine By this point, these analogue machines could already replace human computers in some tasks and were calculating faster and faster, especially when their gears began to be replaced by electronic components.
Zuse and the digital computer Although Turing established what a computer should look like in theory, he was not the first to put it into practice. Credit: Deutsches Museum The first computer that was Turing-complete, and that had those four basic features of our current computers was the ENIAC Electronic Numerical Integrator and Computer , secretly developed by the US army and first put to work at the University of Pennsylvania on 10 December in order to study the feasibility of the hydrogen bomb.

The Colossus was the first electric programmable computer, developed by Tommy Flowers , and was first demonstrated in December The Colossus was created to help the British code breakers read encrypted German messages.
The ABC was an electrical computer that used more than vacuum tubes for digital computation, including binary math and Boolean logic, and had no CPU was not programmable.
Presper Eckert and John Mauchly was invalid. In the decision, Larson named Atanasoff the sole inventor. Presper Eckert and John Mauchly at the University of Pennsylvania and began construction in and was not completed until It occupied about 1, square feet and used about 18, 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.
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, 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 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 was Electronic Controls Company and was founded in by J. In , Konrad Zuse began working on the Z4 that later became the first commercial computer. On April 7, , IBM publicly introduced the , its first commercial scientific computer.
MIT introduces the Whirlwind machine on March 8, , a revolutionary computer that was the first digital computer with magnetic core RAM and real-time graphics. The TX-0 Transistorized Experimental computer is the first transistorized computer to be demonstrated at the Massachusetts Institute of Technology in In , the first desktop computer, the Programma , was unveiled to the public at the New York World's Fair.
It was invented by Pier Giorgio Perotto and manufactured by Olivetti. In , Hewlett Packard began marketing the HP A , considered to be the first mass-marketed desktop computer. Although it was never sold, the first workstation is considered to be the Xerox Alto , introduced in The computer was revolutionary for its time and included a fully functional computer, display, and mouse. The computer operated like many computers today utilizing windows , menus , and icons as an interface to its operating system.
Intel introduces the first microprocessor, the Intel , on November 15, Considered as the first microcomputer, it used the Intel processor and was the first commercial non-assembly computer. In , Ed Roberts coined the term "personal computer" when he introduced the Altair The computer relied on a series of switches for inputting data and output data by turning on and off a series of lights.
The IBM is the first portable computer, which was released in September The computer weighed pounds and had a five-inch CRT display, tape drive , 1. The first truly portable computer or laptop is considered to be the Osborne I , which was released in April and developed by Adam Osborne. Charles Babbage created the concept of a programmable computer. Charles Babbage and the Analytical Engine " ". The first section consists of a series of cogs and gears designed to add up as a replacement for inefficient figure tables.
Six sections of the machine have survived. The Programmer and the Prophet. The first computer that resembled the modern machines we see today was invented by Charles Babbage between and He developed a device, the analytical engine, and worked on it for nearly 40 years. It was a mechanical computer that was powerful enough to perform simple calculations. Is the abacus the first computer?
No, but it is the first-known calculating device. The abacus was first used in B. An abacus consists of a rectangular frame containing thin parallel rods attached with beads for counting.
Who invented the laptop? Adam Osborne built the first laptop in and named it "Osborne 1. What is the first modern computer in the world? Since it was the first computer to use electronic technology, it was nearly 1, times faster than previous computers. It weighed nearly 50 tons as it used 18, vacuum tubes. Sources "Analytical Engine.
