Preface
In modern history, the progress of information technology has a great impact on education. On the one hand, traditional education is facing severe challenges; on the other hand, it also creates good opportunities for the further development of education. With the arrival of the information age, countries all over the world have paid unprecedented attention to the application of information technology in education. The rapid development of technology has made it possible to achieve the previously unattainable means or more ideal teaching methods. However, the reality is not as optimistic as people think. This is because many teachers in classroom teaching cannot effectively use this new technology means and methods to achieve efficient classroom teaching. The reasons are quite complicated, but the main reason is that information technology and classroom teaching fail to form an organic whole. Therefore, to change this situation, some necessary measures must be taken to make information technology play an important role in classroom teaching. However, to make better use of computer teaching, network security must be guaranteed.
This book gives a brief overview of the computer system, introduces modern educational technology and computer aided teaching, and expounds the security management of the network.
前言
在近现代历史上，信息技术的每一项进步，都对教育产生巨大影响。一方面是传统教育面临着严峻的挑战，另一方面，也为教育进一步发展创造了良好的机遇。信息时代的到来，使世界各国对发展信息技术在教育中的应用，都给与了前所未有的关注，以其技术发展极快的特点，使原来可望而不可及的手段或比较理想的教学方式变得可能了。然而，现实的情况并非像人们想象的那么乐观，这是因为许多教师在课堂教学中不能有效地运用这一新技术的手段和方法来实现高效率的课堂教学，究其原因是相当复杂的，但其中最主要的原因是信息技术与课堂教学未能形成有机的整体。因此，要改变这一状况，必须采取一些必要的步骤，使信息技术在课堂教学中发挥重要作用。然而要想更好地使用计算机教学，必须保证网络的安全性。
本书先通过对计算机系统进行简要的概述，接着介绍了现代教育技术、计算机教学，并对网络的安全管理进行了阐述。
