网络对人们的工作学习和生活具有十分重要的作用,那么,网络是怎样产生的呢?我们身边的主要网络又有哪些呢, 关于网络的产生,说法不尽相同。一种说法是:60年代美国的几个研究人员为了共享信息,便把几台电脑连了起来,没想到,改变了世界的网络就这样诞生了。另一种说法比这个站得高些,据说是美国五角大楼的专家们为防止在核战争中中枢系统被核打击后,整个指挥网络陷入瘫痪的局面,由国防部高级研究计划署投资建立的。这个实验性网络证明:计算机可以通过其中任何一条可用
Network is very important to people’s work and study and life. So, how is the network produced? What are the main networks around us? There are different opinions about the network. One argument is that in the 1960s, several researchers in the United States connected computers to share information and did not expect that a network that changed the world was born. Another argument is taller than this one. It is said that experts from the Pentagon of the United States have invested in the Defense Advanced Research Projects Agency to prevent the entire command network from being paralyzed after the nuclear-armed central system was attacked by nuclear weapons. This experimental network proves that a computer can be used by any one of them
