Computer science can be said to be one of the most rapid sciences today. It is dazzling, so you must first include new knowledge into your own system, you must continue to include new knowledge into your own system, and learn new Techniques When you touch the category bypass to achieve a half-time effect.
I understand the computer system:
This architecture is almost the most summary. Each child in the figure is a large field. If network communication is divided into network principles, broadband technology, wireless network, etc.; software engineering is divided into software development, software Management, etc.; just not subdivided in the figure. Each field can be divided into n branches, which can be described as rich in colorful. This picture is just a personal understanding of the computer during learning, so there is no understanding of other computer applications such as bioengineering. This picture is not very comprehensive, because the crosshance of computers is very powerful, this is just from an angle, such as from network communication, there are hardware, such as routers, switches, etc. also belong to hardware. The category, so it is not possible to really clear the limit.
Although the computer is divided into three parts of application, software, hardware, and thus three parts are constantly expanding, this does not mean that the three are isolated, but they are very close, mutual Cross penetration. Such as software engineering involves programming language, algorithm, model, and possibly involving multimedia, database, network communication, information security, etc. There is also more interesting that I will compile, compile, embedded, operating system, etc., between software and hardware, because they do are between hardware and software. Here, I recommend a book "in-depth computer system". One of the biggest features of this book is that the programmer's perspective tells compilation, compilation until the hardware implementation, roaming a computer system. Although I also believe that a book cannot explain so many complex science, at least the author explains some links within the computer system in a unique manner, providing us with a new idea to understand and learn computers. This is the most valuable.
