"The World is digital" reading notes

                         ,         &NB Sp                             "The World is digital" reading notes   &NBSP ;                in today's world, we have to say that the rapid development of science and technology, with the changes of the times, a wave of advanced technology is born, technology has become a measure of the strength of a country's basis. My father witnessed such changes in the times, he told me that in his youth did not have a cell phone, contact with people just use a pager, in my birth soon after the mobile phone is popular, but the screen is small, or the key machine, there are limitations, now, the intelligent machine appeared, screen large, touch screen version, easy to use, full-featured, But the previous key machine has become the old man machine, so big change who does not sigh?       So what is the cause of such a big change? Yes, the computer, computer, is made up of many parts, including many visible peripheral devices, such as hardware, there is no way to see the inner circumference of the equipment, such as software. The computer has its logical structure, including a processor (CPU), some main memory, some large capacity memory, and a variety of other components. The algorithm in the computer is a series of steps to ensure the proper execution of a particular computational process, which is a recipe or a declaration form in computer science, but is compiled more carefully, more accurately and clearly. Each step of the algorithm is expressed as a basic operation whose meaning is fully deterministic, such as "two numbers added". And the procedure and the algorithm also has the inevitable connection, the procedure is not abstract, it states a real computer to complete a task must carry out the concrete steps. The procedure is to the algorithm, like the building to the drawing, one is the actual existence, one is idealized. In other words, a program is one or more algorithms that are expressed in some form that can be directly processed by a computer. The program must take into account the actual problems, such as insufficient memory, slow processor speed, invalid or malicious input, interruption of the network connection, and human weaknesses (which cannot be seen, but often lead to worsening of other problems). So, if the algorithm is an idealized recipe, then the procedure is to let the cooking robot risk enemy fire for the army to prepare one months for the operation of the necessary operations saidThe Ming book.   Two software systems:  operating systems and applications. The operating system is the base layer in the software and it is responsible for managing the computer hardware and providing support for other programs that are called applications. It is very important to learn computer programming well.        reading I see "CPU can dominate their own destiny", it feels a bit absurd, but maybe so. In many American high-tech blockbusters, people think that computers do not have their own thinking, the result is that humans have been the intelligent evolution of the computer occupied their homes, they have created a sense of self, no longer at the mercy of mankind, the continuous slaughter of mankind. Ultimately, the earth is occupied by these higher-intelligence creatures. It makes me feel uneasy, if these creatures of my own family have consciousness, then we can go where to escape. So it has its advantages and disadvantages, because it can bring convenience to human beings and can save mankind a lot of time. And the downside is that it's a time bomb, and no one can know in the future whether they will have their own mind consciousness and then not listen to our demands. If there is this day, it is the Holocaust of mankind, is a disaster!        "The World is digital" is a very good book, Hope in the future study, but also can continue to read such a great work, let their world view become wider.
