下列说法中，正确的是
A．服务器只能用大型的主机、小型机构成
B．服务器只能用安腾处理器组成
C．服务器不能用个人计算机构成
D．服务器可以用奔腾、安腾处理器组成
参考答案：D
解析： 多重处理是指CPU系统，它是高速并行处理技术中最常用的体系结构之一。从奔腾到安腾，标志着英特尔体系结构从IA-32向IA-64的推进。两者的区别在于：奔腾是32位芯片，主要用于台式机与笔记本电脑；安腾是64位芯片，主要用于服务器和工作站。由于服务器和工作站处理的数据量都很庞大，就需要64位的安腾处理器。

| I consider myself something of an expert on apologies. A quick temper has 1 me with plenty of opportunities to make them. In one of my earliest 2 , my mother is telling me, "Don't watch the 3 when you say'I'm sorry'. Hold your head up and look the person in the 4 , so he'll know you 5 it." My mother thus made the key point of a(n) 6 apology: it must be direct. You must never 7 to be doing something else. You do not 8 a pile of letters while apologizing to a person 9 in position after blaming him or her for a mistake that turned out to be your 10 . You do not apologize to a hostess, whose guest of honor you treat 11 , by sending flowers the next day without mentioning your bad 12 . One of the important things you should do for an 13 apology is readiness to 14 the responsibility for our careless mistakes. We are used to making excuses, which leaves no 15 for the other person to 16 us. Since most people are open-hearted, the no-excuse apology leaves both parties feeling 17 about themselves. That, after all, is the 18 of every apology. It 19 little whether the apologizer is wholly or only partly at fault: answering for one's 20 encourages others to take their share of the blame. | ||||
