Most IP layer-bad proxy mechanisms, such as network address translation (NAT), only support uni-directional proxy, from the internal network to external network (the Internet). The proxy establishes the communication channel by (86) IP address. The IP address must be (87) . The proxy mechanisms prevent applications that must establish return data channels from establishing their data channels, such as, multimedia applications. IP layer-bad proxy mechanisms need additional software (88) for each application that us (89) channels. SOCKS identifies communication targets through domain names, overcoming the restriction of using private IP address. SOCKS can u domain names to establish communication between parate LANs, with (90) IP address.

解析：[解析] 大部分基于IP层的代理机制(例如网络地址翻译 NAT)只支持从内部网络到外部网络(Internet)的单向代理。代理通过操作IP地址建立通信通道。IP地址必须是可路由的。这种代理机制使得那些必须建立返回数据通道的应用无法建立它们的数据通道，例如多媒体应用。基于IP层的代理机制对每一个使用多个通道的应用都需要附加的软件模块。SOCKS通过域名识别通信目标，克服了使用专用IP地址的局限。SOCKS可使用域名在各个分离的LAN之间建立通信，这些LAN具有重叠的IP地址。
[分析] 在(86)小题的备选项中，manipulating和conduct都有“操作”的意思，但manipulating侧重于“处理、使用”，而conduct侧重于“引导、管理”。
在(90)小题的备选项中，duplicating 是指“复制、副本”，指完全一样。而overlapping 是指“重叠、交叉”，既有相同的部分，也有不同的部分。
The primary advantages of a Client/Server system ari from splitting the processing between the client system and the databa rver. Since the bulk of the databa proce
ssing is done on the back-end, the speed of the DBMS isn't tied to the speed of the (31) .
The major disadvantage of Client/Server system is the incread cost of (32) and support personnel who maintain the databa rver. There is also the issue of (33) with so many parts comprising the entire C/S system; Murphy's Law can kick in-the more pieces that compo the system, the more pieces that can fail. It's also harder to track down problems when the system (34) . And it can initially take longer to get all the components t up and working together. All this is compounded by the general lack of experience and experti of potential support personnel and programmers, due to the relative newness of the technology. As C/S system become more common, this problem should abate.
Therefore the C/S system is more (35) .

解析：[解析] 客户机/服务器(C/S)系统的主要优点来自它把客户端和数据库服务器的处理进
行分离，因为大量的数据处理放在后台完成，DBMS的速度不会受到工作站速度的影响。
C/S系统的主要缺点是维护数据库服务器的管理和支持人员的成本增加。另外，因为C/S系统由很多模块组成，从而增加了系统的复杂性。Murphy定理表明，组成系统的模块越多，失败的模块就越多。当系统崩溃时，很难跟踪到错误之处。而且，C/S需要首先花很长的时间进行构件开发和组装。因为相对来说，这些技术比较新，缺乏经验、技术支持专家和程序员，但随着C/S系统的普及，这个问题将得到缓解。
因此，C/S系统的效率高，但维护困难。
[分析] 这是一道关于OS结构模式的讨论试题。
C/S是基于资源不对等，且为实现共享而提出来的，是20世纪90年代成熟起来的技术，CIS结构将应用一分为二，服务器(后台)负责数据管理，客户机(前台)完成与用户的交互任务。C/S结构具有强大的数据操作和事务处理能力，处理速度快。但C/S结构维护十分困难，软件只要修改一小点，都要重新安装所有客户端程序。

莲子百合排骨汤解析：[解析] 过去几年中，智能技术已经压了古代演变。第一代以Prolog 和OPS这些工具为代表。Prolog是一个简单的反向链环境，而OPS是一个简单的前向链环境。
这就导致了第二代知识工程环境，其目标是对其知识系统进行建模、原型化和构造。
第三代则更多地关心运行要求、性能、数据库集成、连接性和计算机辅助软件工程——生产性工具。
所有第三代均面向一般问题求解，代表着用于构造专家系统、知识库和人工智能应用的通用实现环境。
某些面向专门求解的产品也同通用知识环境紧密结合，允许最终用户增加用户规则和对象，以及预定义的基于知识的逻辑以处理制造模拟问题。
市场正迅速向着面向专门求解的智能产品环境方向转变。代表着商业企业新的思路和发展的第四代将降低同问题解有关的成本、风险和开发时间。
Today's respon to the data access dilemma eschews the traditional archival approach in favor of emerging standards for what are described as the documents of the future: compound documents. Product urs and developers hope the latest standards effort--such as OpenDoc and Microsoft Corp.'s Object Linking and Embedding (OLE) will (26) data accessibility.
OpenDoc is a standards group (27) a common look and feel throughout documents, even though different applications are ud.
OLE technologies allow Microsoft to (28) its various software products. Microsoft creates, governs and distributes the OLE capability, which is what most (29) it from the open Ope
