Charles Babbage FRS was an English polymath. A mathematician, philosopher, inventor and mechanical engineer, Babbage is best remembered for originating the concept of a programmable computer.

 

 

 

 

 

 

 

 

 

Abacus (plural abaci or abacuses), also called a counting frame, is a calculating tool that was in use centuries before the adoption of the written modern numeral system and is still widely used by merchants, traders and clerks in Asia, Africa, and elsewhere.

 

 

 

 

 

 

 

 

 

 

 

Difference Engine is an automatic mechanical calculator designed to tabulate polynomial functions.

 

 

 

 

 

 

 

 

 

 

 

 

The Analytical Engine was a proposed mechanical general-purpose computer designed by English mathematician and computer pioneer Charles Babbage.

 

 

 

 

 

 

 

 

 

 

 

 

 

z1 was a mechanical computer designed by Konrad Zuse from 1935 to 1936 and built by him from 1936 to 1938. It was a binary electrically driven mechanical calculator with limited programmability, reading instructions from punched tape.

 

 

 

 

 

 

 

 

 

 

 

 

Turing machine is an abstract "machine" that manipulates symbols on a strip of tape according to a table of rules; to be more exact, it is a mathematical model that defines such a device.[2] Despite the model's simplicity, given any computer algorithm, a Turing machine can be constructed that is capable of simulating that algorithm's logic.

 

 

 

 

 

 

 

 

 

 

 

Colossus was the world's first electronic, digital, programmable computer. British codebreakers used Colossus to read secret German messages during World War II.Colossus worked using vacuum tubes. At Bletchley Park mathematician Max Newman had a problem.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The Atanasoff Berry Computer later named the ABC, was built at Iowa State University from 1939-1942 by physics professor Dr. John VincentAtanasoff and his graduate student, CliffordBerry.

 

 

 

 

 

 

 

 

 

 

 

ENIAC (Electronic Numerical Integrator And Computer) was the first electronic general-purpose computer. It was Turing-complete, digital, and capable of being reprogrammed to solve "a large class of numerical problems." 

Though ENIAC was designed and primarily used to calculate artillery firing tables for the United States Army's Ballistic Research Laboratory,[5][6] its first programs included a study of the feasibility of the hydrogen bomb.
