一、网络的选择１．网络操作系统的选择目前,流行于一般局域网用户中的网络操作系统有多种,各用户的条件不同,需求不同,选型也就不同。主要选型有两种：Ｎｅｔｗａｒｅ和ＷｉｎｄｏｗｓＮＴ。ＷｉｎｄｏｗｓＮＴ在学习Ｗｉｎｄｏｗｓ系统、运行多媒体软件,与Ｉｎｔｅｒｎｅｔ网互联等方面具有突出的优势。但它对计算机硬件的配置要求高,这既提高了设备费用,又使一批老式的计算机不能上网。而Ｎｅｔｗａｒｅ在这方面具有明显的优势。因此,我们选用了Ｎｅｔｗａｒｅ３．１２和Ｎｅｔｗａｒｅ４．１的网络平台,它不但具有硬件需求低的… 相似文献

内存管理是计算机操作系统中非常重要的一项功能，在ＤＯＳ操作系统下，内存管理一直是令ＤＯＳ用户较为头痛的问题；在Ｗｉｎｄｏｗｓ操作系统下，内存使用量很大，而内存的大小对Ｗｉｎｄｏｗｓ的运行性影响是很大的，所以一个ＤＯＳ用户或一个Ｗｉｎｄｏｗｓ用户深入了解内存的分布以及管理操作方法是非常重要和必要的，本文对此作了阐述。 相似文献

存储器是计算机系统中必须仔细管理的重要资源。尽管现在计算机的主存容量较大,价格也相对便宜,但由于软件对主存的需求也增大,特别在目前推出基于微机的多任务多线程的Ｗｉｎｄｏｗｓ９５与ＷｉｎｄｏｗｓＮＴ操作系统中要求内存保持较多进程,以改善系统的性能,因而... 相似文献

The communication of people partially is the communication of cultures. Culture has a direct effect on international commercial activities in all aspects. Different conceptions about time, space, equality, law and the like, lead people to deal with things in different ways. So to know cultures of the counterpart is to facil-itate our enterprises so as to have a smooth and successful communication in commercial activity. 相似文献

Given a graph G,a subgraph C is called a clique of G if C is a complete subgraph of G maximal under inclusion and |C|≥2. A clique-transversal set S of G is a set of vertices of G such that S meets all cliques of G. The clique-transversal number, denoted as TC (G), is the minimum cardinality of a clique-transversal set in G. The clique-graph of G, denoted as K (G), is the graph obtained by taking the cliques of G as vertices, and two vertices are adjacent if and only if the corresponding cliques in G have nonempty intersection. Let F be a class of graphs G such that F={G|K(G) is a tree}. In this paper the graphs in F having independent clique-transversal sets are shown and thus TC (G)/|G|≤1/2 for all G ∈ F. 相似文献

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help? 相似文献

Different nations have different social cultures, and the social culture of every nation is developing with the development of the nation, language is greatly influenced by social culture, which enables language to possess national and historical characteristics. Word is the smallest, independent, meaningful linguistic unit of language. It can well reflect the national and historical characteristics. From synchronic aspect, the social and cultural influence on word meaning is mainly embodied in conceptual and associative meanings of word. The incorrespondence of word meaning is a phenomenon that exists in both conceptual and associative meanings of word among different languages. From diachronic aspect, the development of social culture causes some changes of word meaning to some extent. Therefore, social culture plays a key role in vocabulary learning and mastery of a language. 相似文献

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love. 相似文献
