In this video we’re going to talk about computers that changed the world. They are everywhere around us, and without them life as we know it would be a whole different story. So in this video we’ll go back and take a look at the ones that had the greatest impact not just on the industry, but on how we live.
Did you know:
– The Colossus was designed by engineer Tommy Flowers, and influenced by Alan Turing’s use of probability in crypt-analysis. Colossus used vacuum tubes in order to perform Boolean operation, and also required the physical manipulation of telephone jack plugs, cords and switches in order for it to be programmed for new tasks.
– ENIAC: Funded by the US Army, the construction for ENIAC was done in top secrecy. It was built at the Moore School of Electrical Engineering of the University of Pennsylvania, between 1943 and 1945.
– Manchester Baby: Initially not being intended for practical use, it was used as a test for the Williams tube, an early form of computer memory. Unlike previous computers that required physical manipulation for reprogramming, the Manchester Baby was capable of storing program instructions in electronic memory.
– The Xerox Alto is considered to be the first computer to combine a graphical user interface with a mouse driven input, invented by Douglas Engelbart.
– The Altair 8800 was recognized as the spark that ignited the PC revolution! Designer Ed Roberts initially intended to sell just a few hundred kits to hobbyists, but was taken by surprise after the sales were counted by the thousands in just the first month.
– Apple II: In 1976 Apple released the Apple Computer 1, which was designed by Steve Wozniak. But the real boom from this company came one year later, with the release of Apple 2, the computer that would set the standards for PCs for that time.
– IBM 5150: Even though the generic term “personal computer” was in use before, because of the success of the IBM Personal Computer, the term “PC” came to mean more specifically a desktop microcomputer compatible with IBM’s PC products.
– Macintosh: Before the Mac, using computers was not as simple as we know today. To access any program, you would have to have knowledge of proper command lines. Once you had them running, the only way you could interact with them was using the keyboard. With the Mac, starting a program would simply depend on you finding a program icon and double-clicking it using your mouse.
The history of modern computers is filled with many grate machines that had a great impact on the world around us, and the way people get things done in everyday life. Because of their impact on the world, we can say without a doubt that they truly are one of the most important things that man invented.
