Book review: In-depth understanding of computer systems

Today to review: in-depth understanding of computer systems, writing technical articles in the belly of the ink other in too little, just write me read this book sentiment, long ago bought this book, but the revised version. At that time to look at that called a uncomfortable ah, the root of the heavenly book almost. This time to participate in the training, the teacher also mentioned that the book came, and developed the first to read which chapters, and then I was looking for this book has a third version, and is a coloring page, do not say on the next single, I want to insist on slow reading this book, try to do the book exercises (program is how to run up also started) The whole book personal feeling is the expression and processing of information, the program machine-level representation of the two chapters difficult, the 2nd chapter complement, unsigned addition, multiplication, fractional, 3rd Chapter Assembly refers to instructions, because the 3rd version contains 16-bit, 32-bit, 64-bit, so the instructions of the operation of the number of different, need to identify the source, the This is reflected in the exercises in the book. which can not understand the place to go online to see do not know knowledge, such as: The original code, anti-code, the complement of the conversion, signed number and the relationship between unsigned number, as well as fractional in the computer is how to store, and so on, this knowledge of the truth is very low and basic, read the information on the web to fill the gaps in In the 3rd chapter of the Assembly that the understanding of the source, the operand instruction, array, structure, pointer allocation after the bottom of what kind, the stack in the process call also know a lot, some screenshots of the book left in the mobile phone convenient nothing to see. The book in the following chapters on the IO, network, concurrent content in the main entire C code, more suitable for Linux C development students. Like other disk in the book, optimization, virtual memory after reading to the bottom of the computer content also have some knowledge, and then combined with the content of the teacher class, you can say to the computer system understand a lot. Fortunately the first time in-depth understanding of the computer system this book looks almost, the second paragraph intends to look at the Java Basic book, has also done Java development, but forgot almost, rooted teachers and students step by step upgrade self-technology, haha.
