Integrated circuit or IC, which was developed in 1959 and the microprocessor, which first appeared in 1971: personal computers, microcomputers in the field of microelectronics has been made possible by two technical innovations. IC circuit miniaturization of computer memory and microprocessor enables a computer the size of a silicon chip the size reduces the CPU.
Microprocessor of the invention, a machine that thousands of transistors on a tiny silicon chips was equal to San Francisco, California, an area that was designed, developed Santa Clara Valley south of the Ted Hoff developed by Intel Corporation combines the microprocessor industry and equipment, which was there in the world, published as the Silicon Valley. Calculated due to a CPU, is logical operations include manual operation, and data flow management, a system that can function as a complete micro-computer are likely to develop.
First desktop system, which is especially personal use, 1974 Posted to the size, Micro Instrumentation Telemetry Systems (MITS) offered. System owns a popular magazine and journal making technology through the mail order sale of a sports team exposed to the editor. Team, Altair microcomputer kit retail for $ 400.The demand for a little less known, at the same time was overwhelming and totally unexpected. Dozens of small entrepreneurial companies to new markets responded to this demand by producing. First electronics company to manufacture and sell computers, Tandy (Radio Shack) Corporation, introduced its model in 1977. A keyboard and display terminal (CRT): soon dominated the field through a combination of two attractive features. It is also very popular because it can be programmed and the user can store information on tape.
1976 Silicon Valley now, Steve Jobs and Steve Wozniak's what the board house computer chip Jobs 'parents' garage at work called the Apple I, the two men built and local fans and electronic enthusiasts I started Apple market. Jobs and Wozniak in the spring of 1977 this year, Apple Computer, Inc, established in April, Apple II, the world's first personal computer. Its creation, the Apple II, keyboard and capable of performing based on the advice, selling for $ 1290
