The big picture: Intel changed the course of computing, and indeed human history, forever with the introduction of the first commercially available microprocessor. The 50-year-to-date Intel 4004 was launched on November 15, 1971, but it all started a year ago, when Japan's Nippon Calculation Machine Corp. asked Intel to supply a set of integrated circuits for a basic calculator. Create the name from the calculator. Busicom 141-PF.
As Intel explained, initial plans included ten dedicated chips, but the company's engineers were able to adapt the design to only four chips, including the 4004 CPU. Up until that point, it needed computers room-sized to achieve similar levels of processing power. p>

Another thing Fagin didn't do. The speed at which microprocessors have evolved was expected over time and accepted by the industry.Today, it's hard to understand the world without them, and with the constant shortage of chips, we value their presence more than ever. p>
