什么是信息高速公路?由于人们对它理解不一致,因此显然很难获得一个明确的答案。很多电缆电视公司有其自己的见解;而电话公司则有另一种看法。在一旁等待信息高速公路机遇的系统公司和许多部件供应商也有他们的观点。然后,还有一些地地道道的技术人员,他们想利用一种错综复杂的深奥技术来拴住信息高速公路。这最后一种做法可能会导致开发昂贵而不切实际的信息传送设备。 比较切合实际的是,贯穿在以上一些形形色色定义中的共同思路是要实现 What is the information highway? Clear understanding of the people because it is inconsistent, it is clearly difficult to obtain a clear answer. Many cable companies have their own opinions; and telephone companies have another view.

Then, there are a few out-of-town technicians who want to use an intricately esoteric technique to hold the information superhighway. This last practice may lead to the development of expensive and unrealistic messaging equipment. More realistic, the common thread running through some of the above definitions is to achieve
