【正文】 grammers． ? 5. EDI refers to the electronic exchange of business information between two panies using a specific and structured format over private works． 譯： 小型計(jì)算機(jī)網(wǎng)絡(luò)可能僅由家庭中的兩臺(tái)計(jì)算機(jī)組成 ， 它們可以共享打印機(jī)和因特網(wǎng)連接 。 transfer and process a variety of forms of information in a unified manner． ? 8． The data warehouse is the data environment that can be used as the single integrated source of data for processing information． 譯： 信息用戶(hù)只需要處理一個(gè)集成環(huán)境 ， 而不是一系列獨(dú)立的信息子系統(tǒng) 。 譯： 有免費(fèi)的防火墻軟件 ， 可以運(yùn)行在最低的硬件配置上 ， 并能較好地保護(hù)您的網(wǎng)絡(luò) 。 首先 ，我們將論述其拓?fù)浣Y(jié)構(gòu) ， 然后談一些硬件問(wèn)題 ， 包括網(wǎng)絡(luò)設(shè)備和相關(guān)的傳輸介質(zhì)類(lèi)型 。 ? 3． The basic concept of a data warehouse is the difference between data and information． Data is posed of facts that are often found in certain systems ， such as data on student information at a university． In a data warehouse environment， data is only valuable when it is anized and displayed as information． Information is an integrated collection of facts and is used as the basis for decision making． The data warehouse is the data environment that can be used as the single integrated source of data for processing information． ? 譯： 數(shù)據(jù)倉(cāng)庫(kù)的基本概念是數(shù)據(jù)和信息之間的差異 。 數(shù)據(jù)倉(cāng)庫(kù)是一種數(shù)據(jù)環(huán)境 ， 是用于信息處理的單一和綜合的數(shù)據(jù)源 。 在數(shù)據(jù)倉(cāng)庫(kù)環(huán)境中 ， 數(shù)據(jù)只有在組織和顯示為信息后才有價(jià)值 。 有三種常見(jiàn)的拓?fù)浣Y(jié)構(gòu)：星型 、 總線(xiàn)型和環(huán)型 。 ? 1． A puter work links puters together to allow users to share hardware， software， and data， and municate with each other electronically． Computer works exist in many sizes and types． We will discuss the topologies of works first， and then touch on some hardware issues， including the work devices and the types of transmission media involved． Communication works can be classified in terms of their physical arrangement or Topologies． Three mon topologies are the star， bus， and ring． ? 譯：計(jì)算機(jī)網(wǎng)絡(luò)以電子的方式將用戶(hù)的計(jì)算機(jī)連接在一起 ， 用戶(hù)通過(guò)網(wǎng)絡(luò) ， 就可以共享硬件 、 軟件 、 數(shù)據(jù) ，就可以相互通信 。 譯： 數(shù)據(jù)倉(cāng)
