Preface
With the rapid development of the globalization of information, people’s life and work have been becoming more and more intelligent. Computer science and technology plays an important role in the production and life of modern society; it also connects inseparably with the study and life of the public. Computer application technology has the characteristics of wide, professional and open, and now has become an important tool for information collection, processing, integration and application. With the rapid growth of information age, computer science and technology plays a more important and accurate role, pointing out the direction of the development of society. The application of computer science and technology is now the focus in various industries. In this context, the good application effect of computer science and technology will be more prominent.
The information age as a concept has several different interpretations. From one perspective, the development and application of computer technology is the starting point of the information age and the development process of computer science and technology is exactly the process of the development of the information age. The relationship between them is mutual and closely connected. The information age offers a friendly environment for the development of computer science and technology, which makes the important position of computer science technology in the modern society be reflected. The proposing of the big data, cloud computing and other computer technology makes all walks of life be more aware of the importance of information technology and computer science and technology. But at the same time, computer science and technology is also facing severe challenges, which puts forward more strict requirements for the function of computer technology. If computer technology cannot be continuously innovated, it cannot meet the development needs of the times. Therefore, we should increase the frequency of the update of computer science and technology and keep innovating to satisfy the development needs of the information age. The author writes this book from the angle of computer science and technology and application experiment hoping to provide help for the readers.
前 言
随着信息全球化的快速发展，人们的生活和工作越来越智能化。其中，计算机科学技术在现代社会的生产和生活中占有非常重要的地位，公众的学习和生活与计算机科学技术密不可分。计算机科学技术在现代社会的生产和生活中占有非常重要的地位，公众的学习和生活与计算机科学技术密不可分。计算机应用技术具有广泛性、专业性、开放性的特点，已成为信息采集、处理、集成和应用的重要工具。随着信息时代的快速发展，计算机科学技术发挥着更加重要和准确的作用，为社会的发展指明了前进方向，计算机科学技术的应用是各行业关注的热点，在此背景下计算机科学技术良好的应用效果将更加凸显。
信息时代作为一个概念具有多种解释，从一种角度来看，计算机技术的发展和应用是信息时代的起点，而计算机科学技术的发展过程恰恰也是信息时代发展的过程，两者之间的关系是相互的、密切联系的。信息时代为计算机科学技术的发展提供了良好的环境，使得计算机科学技术在现代社会的重要地位得以体现。大数据、云计算等的提出使得各行各业更加认识到信息技术和计算机科学技术的重要性。但与此同时，计算机科学技术也面临着严峻的挑战，对计算机技术的功能提出了更加严格的要求，若不能不断创新，计算机技术则无法满足时代的发展需要。因此，要加大计算机科学技术的更新换代频率，不断创新，满足信息时代的发展要求。编者从计算机科学技术与应用试验角度出发，编写本书，希望能为广大读者提供帮助。
