In-depth Understanding of Computer System Catalogue 2

Today, the author recommends five books to learn about computer systems and computer networks. If you are a computer student or a computer-related worker with an in-depth understanding of computer systems (the second edition of the original book) Introduction: one of the great computer science textbooks.

I have the resources you want here, which can be shared with you for free through Baidu Netdisk: https://pan.baidu.com/s/1UbD27fQ4qDBEZt910ns9Hw Extract code: 1234 "In-depth Understanding of Computer Systems" [4] is reasonable The preferred bibliography of computer systems is the common choice of more than 100,000 programmers.

In-depth understanding of the storage and processing of information in the computer system

The processing, storage and transmission of all information inside the computer is carried out in binary form. The reason why binary is adopted is that binary itself has logical characteristics. Binary refers to the counting system in digital circuits based on the base 2.In this system, binary is usually represented by two different symbols 0 and 1.

C language string: a character array ending with null (value 0), such as the string 12345 encoding is 61 62 63 64 65 using ASCII encoding. The Linux system can use the man ascii command to view the ASCII encoding table. Binary is the core of computer encoding, storing and operating information.

The computer information system that stores and processes state secrets, referred to as the "secret information system", refers to a system composed of computers and their related and supporting facilities and equipment that stores, processes and transmits state secret information in accordance with certain application objectives and rules.

Information system and computer system are two related but different concepts.Information system is a broader concept, which refers to a system in which an organization or entity uses technology and processes to collect, store, process and transmit information. It includes personnel, processes, data, technology and equipment and other components.

Talk about your understanding of computers

Computers areA modern intelligent electronic device that can run according to the program and process massive data automatically and at high speed. It is composed of hardware system and software system. And we are biased towards the software system. It's not that the hardware system is not important. Without hardware, where did the software come from? It's just that we only learned something about computers.

Second, computer science is a very challenging discipline. Learning computer science requires continuous thinking and exploration, and requires certain mathematical and logical thinking ability. This kind of challenge makes me feel very interesting to study computer science-related majors, and I can constantly challenge myself and improve my ability.

Because the computer mainly carried out numerical calculations in the early stage of its appearance, we continued the name "computer".Therefore, when we follow the term "computer", we should have a more comprehensive understanding of the meaning of computer.

Computer resources mainly refer to computer hardware, software and data. 2 Interconnected computers are multiple independent "autonomous computers" distributed in different geographical locations. Networked computers can provide services for both local users and network services for remote users. 3 Networked computers follow a common network protocol.
