Transcript of The Evolution of Computers

by Vignesh Gopalan and John Fridy The Evolution of Computers The very first "automatic computing engine" was created in 1822 by Charles Babbage. It could compute digits and transfer them onto paper, but Babbage never received enough funding to properly manufacture the product. The Beginning Later in 1837, Babbage created the first Analytical Engine. This machine had an Arithmetic Logic Unit, and was the first general mechanical computer. From 1936 to 1938, Konrad Zuse created the first modern computer. A completely functional device dubbed the Z1. It was the first programmable computer. 101 Years Later... In 1943, Tommy Flowers developed and created the first electrical computer, that was also programmable. It was made to help the British crack German codes during WWII. The Colossus The Atanasoff-Berry Computer (ABC for short) was finished by John Vincent Atanasoff and Cliff Berry in 1942 at Iowa State University. It was the first digital computer, and used vacuum tubes to compute Boolean logic and binary math. The Atanasoff-Berry Computer The ENIAC The ENIAC was completed in 1946 by J. Presper Eckert and John Mauchly at the University of Pennsylvania. Although the ABC was the first digital computer, many still look back on the ENIAC as such since it was fully functional. It used 18,000 vacuum tubes and weighed about 50 tons. The EDSAC was the first stored program computer. The British completed it in 1949, and also made it the first computer to run a computer game. The game was named "Baby" and could be played from the computer's memory. The EDSAC IBM On April 7, 1953 IBM introduced to the public the 701, the first mass produced computer. 28 years later IBM came back with the IBM PC, a personal computer that used MS-DOS. It "had a 8088 processor, 16 KB of memory". The 701 The IBM PC
(codename: Acorn) A workstation is basically a computer setup connected to a network or another computer. The first of its kind was revolutionary considering it was fully functional, had a display, and a mouse. It was named the Xerox Alto and was introduced in 1974. It used an operating system with menus and windows much like computers today. The First Workstation In September 1975, IBM introduced the IBM 5100. It had a 5 inch display, 64 KB of RAM, and weighed a total of 55 pounds. It is considered the first portable computer, while the Osborne I is considered the first laptop. The Osborne I weighed 24.5 pounds, and cost 179 dollars. The First Portable Computer The IBM 5100 The Osborne I Computers Today In the year 2012, laptops can have a 3rd generation Intel Core i7-3517U Processor( 1.90GHz 4MB), 17.0" HD Glare screen with integrated camera, Multi-finger one-piece TouchPad without buttons, and 6GB SDRAM RAM. Computers today can have 27 inch monitors, with a 3.1GHz quad-core Intel Core i5 processor, 16GB of memory, with video, camera, and audio support, with wireless keyboards, and multiple extension outlets. These are just some top of the line specifications of today's technology. Plus, the computer has inspired the invention of other products like tablets, e books, iPads, etc. To summarize, we've come a long way. THE FUTURE OF COMPUTERS We predict: computer programmed fully functional robots, hologram monitors, 3D monitors, etc. The possibilities are endless. The End
