Nowadays , the software and hardware architects of computer systems are very complex and are the root of all IT-related technologies . From school to now, I have been trying to start from the original zero-cognition state , and gradually introduce from the most basic digital circuits to computer operating systems and artificial intelligence . Each process cannot be left to learn, from introducing the reason-thinking-introducing the solution-abstracting it into a concept . And they all integrate science and specialty , and use popular and detailed language, diagrams, and models to describe professional knowledge .
The features of this book are as follows:
1. From the perspective of beginners, simple and easy to understand;
2. Introduce things absolutely thoroughly, without leaving any room;
3. Will not gobble up dates, problem-oriented to cause readers to think;
4. A link between the above and the next, everything is related, and each chapter is not an independent part;
5. The overall framework and local details are displayed in detail;
6. Covers digital circuits, analog circuits, computer architecture, computer composition principles, operating system principles, computer graphics, high-performance computer clusters/supercomputers, signals and systems, storage systems, network/communication systems, machine learning, Artificial intelligence, covering a wide range;
7. The pictures are rich and detailed, easy to understand, and each process is dynamic rather than static.
Of course, we will encounter many questions in the process of learning:
1. When you don't understand something at all and you need to study thoroughly first;
2. Without resources, learning encounters bottlenecks, no answers can be found on the Internet, no thinking, and no time to ask others;
3. When you seem to understand but do not understand, when you don’t know how to express, there is no way to get in, no way to start, no way to find a popular description;
4. When you understand thoroughly, you find that things are intertwined and cannot be described from beginning to end from one line. They must be introduced separately from multiple angles;
5. In order to study something thoroughly, when you find that you need to study another series of things first, it is endless, you can't see the head, and feel desperate;
6. When it is necessary to draw a picture, but most of the time it is finished drawing by stitch;

to sum up
Under this proposition that I set up for myself, I really started to build a calculator step by step, and then a programmable calculator, which was the CPU, and finally spread out step by step to sort out the entire system. I sorted out my own thinking, researched and solved problems when I encountered them, and finally became clear. Everything is difficult at the beginning. I think that as long as you start, set some goals for yourself, and then move forward step by step, with perseverance and perseverance, with your own thinking, as long as you step down and record the process, that is A travel note, a valuable book.
To put it bluntly, each of us has our own dreams, but realistic blows often make us degenerate into social animals. In fact, the so-called dreams need to be built on a material basis, so whether you change careers or stick to it in your own industry, you need to spend time and work hard by yourself, but the Internet industry is more effective. Quick, it's relatively easier to stand on the top or top of the pyramid.
