Transcript of Adaptability

Adaptability The Adaptation of the Personal Computer
1970-1990 The Personal Computer, or PC, was made possible by 2 technical innovations. The integrated circuit, or IC, was developed in 1959. It permitted the miniaturization of computer memory circuits. The microprocessor reduced the size of the computer's Central Processing Unit, CPU. It was invented by Ted Hoff at Intel Corporations. The first desktop PC was created in 1974. It was offered by Micro Instrumentation Telementary Systems. (MITS) They called it the "Altair". It cost $400. The high demand for them was unexpected. The second model of the PC was released in 1977. It was put out by Tandy Corporation. It quickly dominated the Altair because it had a keyboard and Cathode-Ray Display. (CRT) It could be programmed and the user could store things by using a cassette tape. Apple Computers "It was a craze that began the whole PC Revolution. People felt they had to have one." -Forrest Mims III, cofounder of MITS Steve Wozniak and Steve Jobs started the Apple Company. They created a homemade Microprocessor Computer Board called Apple I in 1976. In 1977, they founded Apple Computer Inc. In April of 1977,they introduced Apple II. It was the world's first completely working computer. It had a keyboard and color graphics. It cost $1290. The Apple II had expanded memory, inexpensive disk-drive programs, and data storage. Apple Computer Inc. was the fastest growing company in US History. In 1981, IBM came out with their own PC. It didn't have the most recent technology but it proved that PCs were not a fad. They were a necessary tool. Its 16-bit microprocessor initiated the development of faster and more powerful microprocessors. In the mid-1980s, a 32-bit microprocessor was introduced. It was capable of running advanced multi-user operating systems at high speeds. Computers became more "user-friendly" during the 80's. The Graphical User Interface, GUI, allowed users to select icons from a display screen, now called a desktop, instead of having to type commands. In 1980, HP introduced the
first laser printer. Douglas Engelbart created an "X-Y Position Indicator for a display screen." This was the first computer "mouse". It revolutionized personal computers. Microsoft Microsoft Windows was the next-generation operating system that provided a graphical user interface and a multi-tasking environment. IBM tried to compete with Windows by introducing Top View in 1985. It didn't have graphical user interface and was discontinued. "The advance of technology is based on making it fit in so that you don't really even notice it, so it's part of everyday life." -Bill Gates "My professional motivations are strongly oriented toward maximizing the benefit which society might derive from the advancements in the computer field." -Douglas Engelbart Engelbart's first mouse Steve Jobs & Steve Wozniak Apple I Altair "I think it's fair to say that personal computers have become the most empowering tool we've ever created. They're tools of communication, they're tools of creativity, and they can be shaped by their user."
-Bill Gates
