简介:

USB(通用串行总线)是用于将适用USB 的外围设备连接到主机的外部总线结构,其主要是用在
中速和低速的外设USB 是通过PCI 总线和PC 的内部系统数据线连接实现数据的传输USB,
同时又是一种通信协议他支持主系统(host)和USB 的外围设备(device)之间的数据传输/thumb.jpg)
包括一下资料：/thumb.jpg)

USB 的优点:
1.USB 为所有的USB 外设提供了单一的易于使用的标准的连接类型这样一来就简化了
USB 外设的设计同时也简化了用户在判断哪个插头对应哪个插槽时的任务,实现了单一的数据通用接口
2. 整个的USB的系统只有一个端口和一个中断节省了系统资源
3.USB 支持热插拔(hot plug)和PNP(Plug-and-Play) 也就是说在不关闭PC 的情况下可以
安全的插上和断开USB 设备计算机系统动态地检测外设的插拔并且动态地加载驱动程序其他
普通的外围连接标准如SCSI 设备等必须在关掉主机的情况下才能插拔外围设备
4. USB在设备供电方面提供了灵活性USB直接连接到Hub 或者是连接到Host 的设备可以通过USB 电缆
供电也可以通过电池或者其它的电力设备来供电或使用两种供电方式的组合.并且支持节约能源的挂机和唤醒模式
5. USB 提供全速12Mbps 的速率和低速1.5Mbps 的速率来适应各种不同类型的外设
USB2.0 还支持480Mbps 的高速传输速率
6. 为了适应各种不同类型外围设备的要求USB 提供了四种不同的数据传输类型控制传输Bulk
数据传输中断数据传输和同步数据传输同步数据传输可为音频和视频等实时设备的实时数据传输提供固定带宽
7. USB 的端口具有很灵活的扩展性一个USB 端口串接上一个USB Hub 就可以扩展为多个USB端口/thumb.jpg)

warning。。。f-secure client secruity 7.01 build 104提示有如下病毒
"Virus.MSWord.Thus.ew”
F-Secure Virus Descriptions : Thus
NAME: Thus
ALIAS: Thursday
Thus is a Word 97 macro virus that has a destructive payload.
Many Thus variants activate their payload at December 13th. Then the virus deletes all files from the root of "C:" drive and from all its subdirectories, but it does not delete directories themselves. Only files with system, read-only or hidden attribute set are left. After deletion the system cannot be restarted any more. Files may be still recoverable with a suitable recovery software. However, if the system has been used since the activation, then it is likely that files have been already overwritten. In that case files should be restored from backups.
VARIANT: Thus.A
When an infected document is opened, W97M/Thus.A will infect the global template as well as every currently open document in Word. After that every document that is created, opened or closed will be infected.
The virus detects already-infected documents by looking for this marker:
Thus_001
This is why the virus was named "Thus". The virus is also known by the alias "Thursday".
The virus activates its payload at December 13th, when it deletes most of the files from the root of "C:" drive and from all its subdirectories. Only files with system, read-only or hidden attribute set are left. After deletion the system cannot be restarted any more.
The virus is not visible in any way. It has been reported in the wild globally during September 1999.
VARIANT: Thus.B
This variant is functionally identical with W97M/Thus.A. The only difference between these two are that this variant has a few apostrophe style commented empty lines at the end of its code.
VARIANT: Thus.J
W97M/Thus.J is a modified variant of W97M/Thus.A - the payload is different. This variant activates its payload at November 3rd, when the virus attempts to create a plain text file, "C:\000_new\Thus_100.txt".
