After reading this book I envy von Neumann this person, because he invented the computer, computer is one of the most advanced scientific and technological inventions in the 20th century, the production of human activities and social activities have a very important impact, and with a strong vitality of rapid development. Its application field extends from the initial military research application to all areas of society, has formed a large scale computer industry, led the global technological progress, resulting in profound social change, the computer has spread throughout the general school, enterprises and institutions, into ordinary people's homes, to become an indispensable tool in the information society. Computer applications in China more and more common, after the reform and opening up, the number of Chinese computer users continue to rise, the application level is constantly improving, especially in the Internet, communications, multimedia and other fields of application has achieved good results.

This book, let me have a more understanding of the computer, which impressed me is the operating system, because the operating system is to manage, control and supervise the computer software and hardware Resources coordinated operation of the program system, by a series of different control and management functions of the program, it is directly run on the computer hardware, The most basic system software is the core of system software. Operating system is the product of computer development, its main purpose is two: one is convenient for users to use the computer, is the user and computer interface. For example, the user can type a simple command to automate complex functions, which is the result of operating system help, the second is to unify the management of all the resources of the computer system, reasonably organize the work flow of computers, in order to fully and rationally exert the efficiency of the computer.

Now no matter save, take money, stocks, online shopping, or e-commerce, and even aviation, postal and other industries to use the computer. And with the development of the computer-the emergence and popularization of the network, it is greatly promote and facilitate the economic market transactions, determine the lifeblood and direction of the economy.
