根据程序局部性理论，Denning提出了工作集理论。工作集是进程运行时被频繁访问的页面集合。在进程运行时，如果它的工作页面都在 (1) 器内，能够使进程有效地运行，否则会出现频繁的页面调入/调出现象。
假设窗口尺寸为10，在某一段时间内，进程所访问的逻辑页面顺序如图1-2所示，那么在t₁时刻的工作集是 (2) 。

某局域网通过两台路由器划分为3个子网，拓扑结构和地址分配如图1-7所示。

R2(config)#int e0
R2(config-if)# (1)

Prior to the availability of enterprise EDM, locating a document over a LAN could be difficult, and over a WAN (1) nearly impossible. With the model for collaborative work spreading, and with more users sharing (2) documents through e-mail and the Internet, enterprise EDM had become a necessity.
Many businesses are finding their greatest competitive advantage is the ability to harness the document (3) lifecycle. EDM systems manage this lifecycle from creation, revision, storage and (4) retrieval to routing and workflow. They also allow users to work on documents collaboratively.
Reusability of information is EDM’s main benefit, as well as the key to creating the paradigms that drive business process (5) reengineering.

Pharming is a scamming practice in which malicious code is installed on a personal computer or server, misdirecting users to (1) fraudulent Web sites without their knowledge or consent. Pharming has been called "phishing without a lure".
In phishing, the perpetrator sends out legitimate- (2) looking e-malls, appearing to come from some of the Web’s most popular sites, in an effort to obtain personal and financial information from individual recipients. But in pharming, larger numbers of computer users can be (3) victimized because it is not necessary to target individuals one by one and no conscious action is required on the part of the victim. In one form of pharming attack, code sent in an e-mail modifies local host files on a personal computer. The host files convert URLs into the number strings that the computer uses to access Web sites. A computer with a compromised host file will go to the fake Web site even if a user types in the correct Internet address or clicks on an affected (4) bookmark entry. Some spyware removal programs can correct the corruption, but it frequently recurs unless the user changes browsing. (5) habits,
