I believe that in spite of what people say, Bill Gates has been a benefactor of mankind. Simply said, there were a number of processors, all doing more or less the same thing. He said, let's just pick one, and it's Intel's. Then, yesterday there were a lot of operating systems. Well, let's take one.
All operating systems are the same.
There is no practical difference. And then he went one step further. He, Gates, applied standardization principles by saying, one processing chip, please, one operating system, please. Copyright 2000, The Institute of Electrical and Electronics Engineers, Inc.
