Software, can't see, touch, no way to fall; but it seems that illusory software is in our lives, creating human future. It seems too big, but you will see how you look at "Software" concept. In general, essential software should refer to human thinking, right, referring to human thinking; while the software, the software is the computer software we are confirmed. What is the connection between the broad software and the narrow software? Performance and simulation! Do not use it, the process of human development evolution is the process of human thinking and exploration. (My friend is more directly. He believes that the process of human development is to constantly learn to lazy process. It seems to be in the process of thinking in such thinking and exploration. Computers are humanity for their own performance and simulation, and there are many common things between her and humans. This is also the root cause of such a wide range of applications in such a broad field. Standing on this level and looking back at the computer, she should not be a computer, maybe she is more appropriate to call her behavior or simulator. Computers are no longer a desktop, portable machine, microcomputer, such as desktop, portable machine, microcomputer, etc., should be present in a variety of forms, but everywhere, no time. We are fortunate to engage in computer software design, because we can think more about others, to review, summarize, go to learn. What we are engaged in a great career because she can change human life and promote human innovation. To learn to think, learn to create, use a peace, excitement, curious heart to create!
