計算機發展史(英語版)

History,Of computer development,Electronic computer,In 1946 Pennsylvania University in the USA developed the first electronic computer in the world through several years“ hard efforts.“,ENIAC兩位設計者 莫契利和埃克特,Transistor computer,In the late 1960s and early 1970s, engineers made great strides(進步) in reducing the size of electronic components. They developed the semiconductor chip半導體芯片, which was about the size of a fingenail and could contain hundreds of transistors.,1955年，貝爾實驗室使用800只晶體管組裝了世界上第一臺晶體管計算機TRADIC。 Transistor Digital Computer,Personal Computer,In 1981, International Business Machines IBM, the largest computer company in the world, introduced its own microcomputer, dubbed the IBM PC “PC” is the abbreviation for personal computer.,The First IBM PC,,This computer is small in size and you can easily arrange it to fit in your bedroom with its all .Today this is thought to be the most popular computer in all.,Todays day,Sit down in front of an iMac and something incredible happens The world around you seems to disappear, and you lose yourself in the big, beautiful display. To create an experience this immersive身臨其境, we pushed every limit, considered every detail, and advanced iMac in astonishing驚奇ways.,Weve gone to extraordinary lengths.

Today, iMac includes a brilliant desktop display, and its filled with the latest high-perance technologies. Yet its just 5 mm thin at its edge.,The development of computer technology has the following four characteristics 1. multi-polarization多極化 2. Intelligent智能化 3. networked網絡化 4. multimedia多媒體,計算機的未來發展趨勢,DNA計算機,激光計算機,量子計算機,納米計算機,Fifth generation computer refers to a new generation of computers, with artificial intelligence, it has the reasoning, lenovo, judgment, decision making, learning, and other functions. These computers are superconducting computers, nano computer, light computer and DNA computer and quantum computer, etc.,,Fifth generation computer refers to a new generation of computers, with artificial intelligence, it has the reasoning, lenovo, judgment, decision making, learning, and other functions. These computers are superconducting computers, nano computer, light computer and DNA computer and quantum computer, etc.,,第五代計算機是指新一代的計算機，人工智能，它具有推理，聯想，判斷，決策，學習等功能。 這些計算機有超導計算機，納米計算機，光計算機和DNA計算機和量子計算機等。,Computer is to use the laser as a carrier of ination processing of computer, also called is, their speed will be at least 1000 times faster than ordinary computers. It relies on a laser beam(激光束) into composed of a reflector(反射鏡) and lens array透鏡陣列 to the ination processing.,The End,Thank you,
