History of Computers

This device was as large as a house and powered by 6 steam engines,

First Machine to store data as a charge on a capacitor, which is how today's computers store information in their main memory. It is the first fully electric but not programmable machine that got built.

Analytic Engine

This device was as large as a house and powered by 6 steam engines,

Stepped Reckoner

A four-function (addition, subtraction, multiplication, and division) calculator, that had used ten flutes arranged around their circumference in a stair-step fashion instead of having gears.

Machanical Calculating Aid

Abacus

Aided the memory of the humans that performed the calculations.

Logarithms(AKA. Napier's Bones)

Allowed multiplication to be performed through addition

Slide Rule

First built in England in 1632, and was still in use in the 1960's by the NASA engineers of the Mercury, Gemini, and Apollo programs.

Calculating Clock

The first gear-driven calculating machine that was built.

Pascaline

A gear-driven, one-function calculator which could only add and wasn't very accurate.

Power Loom and the Punched Cards

It based its weave and which helped to make the design on the fabric in a pattern that was automatically read from punched wooden cards, which were held together in a long row by rope., First Computer that wasn't used to make calculations for humans and just sped up the mill work, But later the punched card idea was used to do much more.

Difference Engine

This machine was a steam driven calculating machine the size of a room would be able to compute tables of numbers, like logarithm tables, but the device was never completed.

Analytic Engine

This device was as large as a house and powered by 6 steam engines,

A four-function (addition, subtraction, multiplication, and division) calculator, that had used ten flutes arranged around their circumference in a stair-step fashion instead of having gears.

A motorized typewriter that could transmit keystrokes to the mainframe and then print the computer's response on its roll of paper.

Electrical Computing

Mark I

The first programmable digital computer made in the United States, but wasn't a purely electronic computer, rather half mechanical.

Atanasoff-Berry Computer

First Machine to store data as a charge on a capacitor, which is how today's computers store information in their main memory. It is the first fully electric but not programmable machine that got built.

Electronic Numerical Integrator and Calculator(ENIAC)

It employed paper card readers obtained from IBM. It was sielent but it was on, as the 18,000 vacuum tubes each generated waste heat like a light bulb

Colossus

Was built during the WWII to decode the German Codes.

Universal Automatic Computer(UNIVAC)

The first computer to employ magnetic tape.

Teletype
