Z3
Konrad Zuse introduced the first programable computer in 1941. An electromagnetic computer for which program and data were stored on external punched tapes. This device was capable of calculating aerodynamics in aircraft design. -
First Electronic Computer : Atanasoff-Berry Computer
The first electronic computer, (ABC) was used to find solutions for simultaneous equations. This invention was designed by John Vincent Atanasoff & Clifford Berry. ABC used binary to represent data and electronic switches instead of mechanical. The computer was not programmable. -
First Programmable Electronic Computer: Colossus
The Colossus was created by Tommy Flowers. World War II.This electronic computer was programmed by electronic switches and plugs. Colossus decreased wait time when deciphering encrypted messages during WW2 significantly. -
First General Purpose Programmable Electronic Computer: ENIAC
ENIAC or Electronic Numerical Integrator And Computer was developed by John Mauchly & J. Presper Eckert. ENIAC programming was done by altering its electronic switches and cables. It used card readers for input and card punches for output. Helped compute equations faster than any computer before. -
Computer Mouse by Ralph Benjamin
Ralph Benjamin had built a prototype in 1946 when he was working as a Royal Navy technician. This device was known as a “tracker ball”, a stationary upside-down version of the mouse. User could move a cursor on a radar screen by sliding their palm over a metal ball rolling on two rubber-coated wheels and set in a casing.
The tracker ball allowed users to control their on-screen movements with greater precision than was possible with the more familiar joystick.
