在21世纪,随着电脑的主要零件——微处理机体积的缩小和价格不断下降,电脑将成为各种生活用品内部的控制部件,例如,在最近出厂的汽车中,电脑便控制着汽车的发动机、变速箱、冷气、防滑刹车、防盗系统、调速系统等。到21世纪,电冰箱、洗衣机、烘干机、烤箱、音响设备、录像机等家庭日用品都会有一个小型电脑,藏在看不见的地方。每一个家庭。每一座房屋,都会有几十台电脑在屋内的各个角落,控制安全系统、暖气、冷气、灯光、自动照顾后院的花草,甚至给狗、猫喂食。在21世纪,电脑不仅会无处不在,而且会通过各种方式。连接起来。其中一种重要方式是通过电波传送到绕着地球运行的通讯卫星,再由通讯卫星传送到世界各地。这样无所不在的联网。会使人们的生活发生巨大的变化。例如,每一辆出厂汽车里的电脑,不但随时随地地控制汽车和记述汽车的运行情况,而且把每一辆汽车的运 In the 21st century, with the shrinking of the size and price of the main part of the computer, the size of the microprocessor, the computer will become the internal control component of various daily necessities. For example, in the recently released car, the computer controls the car Engine, gearbox, air conditioner, anti-skid brakes, anti-theft system, speed control system. By the 21st century, household appliances such as refrigerators, washing machines, dryers, ovens, audio equipment, video recorders and the like will have a small computer hidden in invisible places. Every family. In every house, there are dozens of computers in every corner of the house that control security systems, heating, air conditioning, lighting, auto-care of backyard flowers, and even feeding dogs and cats. In the 21st century, computers will not only be ubiquitous, but also come in various ways. connect them. One of the important ways is to send it over radio waves to communication satellites that operate around the earth and then transmit it to all over the world by communication satellites. This ubiquitous networking. Will make a huge change in people’s lives. For example, a computer in each factory car not only controls the car and records the operation of the car anytime, anywhere, but also loads the car
