The term Web server is sometimes also used to refer to the physical computer that runs Web server software. Leading manufacturers of Web server computers are IBM, Compaq, Dell, and Hewlett Packard. Although any personal computer can run Web server software, it is best to use a computer that has been optimized for this purpose. To be a Web server, a computer must have the Web server software described above installed and be connected to the Internet. Every Web server machine has an IP address.
術(shù)語網(wǎng)絡(luò)服務(wù)器有時也被用于指運(yùn)行網(wǎng)絡(luò)服務(wù)器軟件的實(shí)際計(jì)算機(jī)。網(wǎng)絡(luò)服務(wù)器計(jì)算機(jī)的制造商是IBM(國際商用機(jī)器公司)、Compaq(康柏)、Dell(戴爾)和Hewlett Packard(惠普)。雖然任何個人計(jì)算機(jī)都能運(yùn)行網(wǎng)絡(luò)服務(wù)器軟件，但是使用一部為這個目的化的計(jì)算機(jī)。作為一個網(wǎng)絡(luò)服務(wù)器,一部計(jì)算機(jī)必須安裝上述網(wǎng)絡(luò)服務(wù)器軟件且聯(lián)接到因特網(wǎng)。每部網(wǎng)絡(luò)服務(wù)器計(jì)算機(jī)有一個IP地址。
Aside from the generic Web server software packages, there are actually many types of specialized servers on the Web, from database servers that access specific information with a database, to ad servers that deliver targeted banner ads, to mail servers that provide mail messages, and video servers that provide video clips. At a small e-commerce site, all of these software packages might be running on a single machine, with a single processor. At a large corporate site, there may be hundreds of discrete machines, many with multiple processors, running specialized Web server functions described above.
除了一般的網(wǎng)絡(luò)服務(wù)器軟件包之外，網(wǎng)絡(luò)上其實(shí)還有許多類專用服務(wù)器, 從訪問數(shù)據(jù)庫特定信息的數(shù)據(jù)庫服務(wù)器, 到遞特定標(biāo)題廣告的廣告服務(wù)器,到提供郵寄信息的郵件服務(wù)器,以及提供視頻剪輯的視頻服務(wù)器。在一個小型電子商務(wù)網(wǎng)站，所有的這些軟件包可能在一部具有一個處理器的機(jī)器上運(yùn)行。在一個大公司的網(wǎng)站,可能有數(shù)百臺分布的機(jī)器, 多數(shù)具有多個處理器,運(yùn)行上述特定的網(wǎng)絡(luò)服務(wù)器功能。
A Web client, on the other hand, is any computing device attached to the Internet that is capable of making HTTP requests and displaying HTML pages. The most common client is a Windows PC or Macintosh, with various flavors of UNIX machines a distant third.
另一方面，網(wǎng)絡(luò)客戶機(jī)是指任何一種聯(lián)接到因特網(wǎng)、能夠發(fā)出HTTP請求并顯示網(wǎng)頁的計(jì)算裝置。最常見的客戶機(jī)是采用Windows操作系統(tǒng)的個人計(jì)算機(jī)或麥金托什機(jī),各種不同風(fēng)格的UNIX機(jī)遠(yuǎn)遠(yuǎn)排在第三。
