1.Introduction

At the heart of almost every computer security architecture is a set of cryptographic protocols that use cryptography to encrypt and sign data.They are used to exchange con?dential data such as pin numbers and passwords,to authentify use

Abstract. In this paper we study dynamic properties of knowledge-based systems. We argue the importance of such dynamic properties for the construction and analysis of knowledge-based systems. We present a case-study of a simple classification method for w

开机提示Verifying DMI Pool Data的解决

DMI是英文单词Desktop ManagementInterface的缩写，也就是桌面管理界面，它含有关于系统硬件的配置信息。计算机每次启动时都对DMI数据进行校验，如果该数据出错或硬件有所变动，就会对机器进行检测，并把测试的数据写入BIOS芯片保存。所以如果我们在BIOS设置中禁止了BIOS芯片的刷新功能或者在主板使用跳线禁止了BIOS芯片的刷新功能，那这台机器的DMI数据将不能被更新。如果你更换了硬件配置，那么在进行WINDOWS系统时，机器仍旧按老系统的配置进行工作。这样就不能充分发挥新添加硬件的性能，有时还会出现这样或那样的故障。如果我们在启动计算机时看到上述这个信息后，系统长时间停止不前或处于死机状态，对于机器此类故障一般很难处理。因为不能像进入系统后出现的故障，我们可以检查系统日志之类的文件进行分析。不过，根据PC机启动的过程原理分析，出现这条信息时一般有以下的可能情况：1.硬件改变

当主机的硬件配置有所变化，但是我们使用的是POST功能时，此时系统不能识别新添加的硬件，将会按老的配置进行工作，此时就会出现
