This document provides a brief history of the evolution of computers from the 1930s to present day. It describes some of the earliest electronic digital computers like the ABC and Z3 and how they were used. It then outlines the development of Colossus, the Mark I, ENIAC, and EDVAC and notes technological advances like stored programs. Later sections discuss the first commercial computer UNIVAC I and large systems like SAGE. The document concludes by mentioning the development of transistors, microprocessors, GUIs, and advances like Deep Blue, virtual reality, robots like ASIMO, and the future of computing.

1. Evolution
of a
Computer

2. Atanasoff-Berry Computer (ABC)
• Designed in 1937 by John V. Atanasoff and
Clifford Berry, it is the world’s first electronic
digital computer.

4. Z3• Secretly developed in 1941 by the German
engineer Konrad Zuse. It was use to design
airplanes and missiles.

5. Colossus
• Designed in 1943 by British scientist Alan
Turing. It was used to decode German
messages.

6. Harvard-IBM Automatic Sequence
Controlled Calculator or Mark I
• Developed in 1944 by Howard H. Aiken, this is
used by the US Navy.

7. Electronic Numerical Integrator
and Computer (ENIAC)
• Designed in 1945 by John Presper Eckert Jr.
and John Mauchly, it is used by the U.S. Army.

9. Electronic Discrete Variable
Automatic Computer (EDVAC)
• Designed in 1945 by John von Neumann, it
had a memory that could hold both data and a
stored program.

10. Universal Automatic Computer
I (UNIVAC I)
• Built in 1951 by Remington Rand and the first
commercial computer to feature a magnetic
tape storage system.

11. Semi-Automatic Ground
Environment (SAGE)
• Established in 1954, this automated aircraft-
warning system has the largest vacuum tube
computer system ever built.
