摘要
本文从论述微机系统的数据安全性入手，分析了用纯硬件电路保护微机数据安全性的方法及采取的措施，论述了所设计的硬盘写保护卡的设计思路、功能、效果等，硬保护是一种更简单、可靠、廉价的数据保护措施。
Starting with the problem of the data security of the PC. This paper analyses the method of using hardware circuit to protect the data security of the PC and the adopted measure. It discusses the design idea, function as well as the result of the designed 'hard disc writing protecting card'. The author's conclusion is that 'hardware protection' is simpler, more reliable and cheaper measure of data protection for PC.
