它重达30吨英文

世界上第一台计算机在美国的宾西法尼亚大学里面诞生的! 当时叫做电子数字积分机和计算机（Electronic Numerical Intergrator and Calculator,简称ENIAC）.ENIAC是一个庞然大物,它使用了18000多只电子管,1500个继电器,功率14O千瓦,重量 30吨,占地约 170 平方米,运算速度达到每秒5000次.

你看看吧，不合适的地方再改改吧...应该问题不大...Know to all, our modern living at information ages.Today, our lifes can not get away from a computer, it integrated into our lifes and silently contributed efforts to us.For example, our traffic lights from computer control of.If we want long trip, the train is also adjusted a degree by computer.Therefore, if there is no computer, our modern lifes will become confusion.Computer thus important, but its importance is a gradual embodiment in its development.The earlier period that develops at the mankind, in order to living a demand, the people usage pebble counts.Along with the emergence of the trade, this kind of counts way inconvenience at the operation, hence invented abacus.The abacus is Chinese great invention, it can calculate is an up the earliest calculator.Along with the usage of electricity, the mankind invented an electronics equipments and used for acting for a traditional handicraft calculation.Mankind the first set calculator is ENIAC, it is born in 1946.It is very huge and weigh up to 30 tons, 10 equal to sizes of rooms.After first set calculator appeared, more and more high performance calculators are developed.Currently, the calculator is divided into 3 types according to the physical volume:Large calculator, household-use calculator(is also a PC) and microcomputer.The large calculator mainly useds for a war, finance calculation, weather calculation.For example, the atomic bomb develops, the trend, satellite image of stock, all can not get away from its help.The PC is mainly useds for transacting an automation, amusement, on-line surfing, is our living service.The PC machine is divided into a set type computer and notebook.The microcomputer is again called a handheld PC, for example the intelligence cellular phone is a microcomputer.Believe near future, compute function to pack into watch, glasses.In the future, the calculation function installs in the robot and make it produce artificial intelligence, is also an AI.From 《 the AI 》 this movie, we can know, the mankind can become a friend with robot.Can know from the top, the development of calculator makes the mankind more and more can not get away from it, it will always behavior serve.

As we all know, we now live in the information age. Today, our lives can not be separated from the computer, it integrated into our life, in silence for our service. For example, our traffic light is controlled by computer. If we are to long-distance travel, the train scheduling by computer. Therefore, if there was no computer in our modern life would be chaos. The computer is so important, but its importance is gradually developing in its embodied. Early in human development, as a result of needs, the use of stones count. With the emergence of trade, which facilitate the operation count of the way, they invented the abacus. Thinking is the greatest invention of the Chinese people, it can be considered is one of the first calculator. With the use of electricity, the human invention of electronic equipment, used to replace the traditional manual calculation. The first human computer called ENIAC, it was born in 1946. It is very large, weighing 30 tons, which is equivalent to the size of the room 10. Since the emergence of the first computer, an increasing number of high-performance computers has been developed out. At present, the computer according to size into three categories: large-scale computer, home computer (ie PC), micro-computer. Mainly used for large-scale computer war, the financial terms, meteorological computing. For example, the development of the atomic bomb, stock trends, satellite images, we can not do without its help. PC mainly used in office automation, entertainment, Internet surfing, for the services of our lives. PC machines are divided into desktop and notebook computers. Micro-computer, also known as Pocket PC, such as smart phones, that is, micro-computer. I believe the near future, the computer can be put into watches, glasses in. In the future, the computer can be installed on the robot so that it produced in artificial intelligence, that is AI. From the "AI" movie, we can know that the human and robot can become friends. From, we can see that the development of the computer can not do it more and more human, it will have to serve mankind.
