Clustering
Collections of machines in a fixed configuration designed to operate and be managed as a single machine. Differs from grid computing where resources can enter and leave the pool as necessary.
集群
指设计成按单一机器进行操作和管理的固定配置，它将多台机器集合起来（工作）。它与网格计算不同，在网络中资源可以按需要进入或离开这个集合。
Transflective
A type of LCD screen in which the pixels are illuminated from both the front of the monitor's screen and from behind the screen, combining the illumination characteristics of both transmissive and reflective technologies. Transflective LCDs work under any lighting condition, from complete darkness to bright sunlight.
传输反射型
它是液晶显示屏的一种类型，其像素是从屏幕正面和背面两个方向照亮的，它综合了传输型和反射型技术的两种照明特性。传输反射型液晶显示器能在任何光照条件下工作，从完全黑暗到明亮的阳光下都能工作。
Directory Harvest Attack
A directory harvest attack (DHA) is an attempt to determine the valid e-mail addresses associated with an e-mail server so that they can be added to a spam database. A directory harvest attack can use either of two methods for harvesting valid e-mail addresses. The first method uses a brute force approach to send a message to all possible alphanumeric combinations that could be used for the username part of an e-mail at the server. The second and more selective method involves sending a message to the most likely usernames - for example, for all possible combinations of first initials followed by common surnames. In either case, the e-mail server generally returns a “Not found” reply message for all messages sent to a nonexistent address, but does not return a message for those sent to valid addresses. The DHA program creates a database of all the e-mail addresses at the server that were not returned during the attack.
目录收割攻击
目录收割攻击（ DHA ）是试图确定与一台电子邮件服务器有关的有效电子邮件地址，从而把这些地址加入垃圾邮件数据库。目录收割攻击能利用两种方法收集有效电子邮件地址。第一种是利用暴力法，给可以用作电子邮件用户名部分的所有可能的数字字母组合发消息。第二种也是更常选用的方法是给最有可能的用户名发消息，如常用姓前面的所有可能的名字缩写组合（译注 : 西方人将名放在姓前，并将名字缩写，如 P.J.Smith ）。在每一种情况下，电子邮件服务器通常都会给发送给不存在的地址的消息回复一个 “ 未找到 ” 的信息，但是那些发送给有效地址的消息不会被回复这样的信息。据此 DHA 程序就生成一个数据库，把攻击中没有被返送回来的电子邮件地址记录下来。
