一個(gè)可編制程序的機(jī)器。計(jì)算機(jī)的二種主要特性是:它響應(yīng)一個(gè)具體的指令為一個(gè)明確定義的方式.現(xiàn)代計(jì)算機(jī)是電子和數(shù)字化的。現(xiàn)有機(jī)器--電線，晶體管和電路--被稱為硬件；指令和數(shù)據(jù)被稱為軟件。

所有通用計(jì)算機(jī)要求以下硬件元件:

物理內(nèi)存：使計(jì)算機(jī),至少臨時(shí)地,存放數(shù)據(jù)和節(jié)目。一個(gè)可編制程序的機(jī)器。計(jì)算機(jī)的二種大容量存儲(chǔ)器設(shè)備:允許計(jì)算機(jī)永久地保存很多數(shù)據(jù)。大容量存儲(chǔ)器設(shè)備普遍包括驅(qū)動(dòng)器和磁盤(pán)驅(qū)動(dòng)器。

輸入設(shè)備:通常是鍵盤(pán)鼠標(biāo),輸入設(shè)備是數(shù)據(jù)和指令進(jìn)入計(jì)算機(jī)的途徑。

輸出設(shè)備:顯示器、打印機(jī),或其他可以讓您看到計(jì)算機(jī)完成了什么的設(shè)備。中央處理單元(CPU):計(jì)算機(jī)的心臟部分，是實(shí)際上執(zhí)行指令的部件。除了這些部件,使得許多其他的基本部件一起實(shí)現(xiàn)高效率地工作成為可能。例如,要求一個(gè)巴士傳送一個(gè)計(jì)算機(jī)上的一部分?jǐn)?shù)據(jù)到另外的巴士上去.電腦根據(jù)體積和重量大致分類如下,雖然有有可能的交叉：個(gè)人計(jì)算機(jī)（PC機(jī)）:一個(gè)小的、單用戶的電腦微處理器.除微處理器之外,一臺(tái)個(gè)人計(jì)算機(jī)有一個(gè)鍵盤(pán)用來(lái)輸入數(shù)據(jù),一個(gè)顯示器用來(lái)顯示信息,還有存貯設(shè)備用來(lái)保存數(shù)據(jù)。工作站:一個(gè)強(qiáng)大的、單用戶計(jì)算機(jī).就是一臺(tái)個(gè)人計(jì)算機(jī),但它有個(gè)更強(qiáng)大的微處理器和更優(yōu)質(zhì)的顯示器。·小型機(jī):多用戶電腦，可支持10到上百用戶同步.

·主機(jī):一個(gè)強(qiáng)大的多用戶電腦，可支持多用戶或成百上千的用戶同步.

·大型機(jī):一個(gè)非?？斓挠?jì)算機(jī)，能每秒響應(yīng)億萬(wàn)個(gè)指令.Discusstogetherandthendecidewhichkindofcomputeryouwouldliketobuyforyourschool.DiscussionA:Lookatthiscomputer.Ithasbeengivenasmallermonitor.B:That’sgoodbecausewecanthenhavemorecomputersintheschool.DoesithavetheInternetaswell?Sampledialogue:A:Youcanhaveitfittedbutitisnotincludedintheprice.Nowlookatthisone.Bothasmallmonitorandaflatscreenhavebeenincluded.ItcanbejoinedtotheInternetstraightawayandithasbeengivenalargeharddisccapacity.That’sgoodofcourse.B:Doyouthinkweshouldbuylaptopcomputersforourschool?Theyaremoreusefulbecausetheycanbemovedfromroomtoroom.Theschoolwouldnotneedtoprovideaspecialroomforcomputers.Theyarealsosmallerandcanbestoredawaymoreeasily.Buttheyhaveprovedtobemuchmoreexpensivethanapersonalcomputer.A:Yes,thatiswhytheprincipaltoldmewecouldnotbuythem.Hewouldnotbeabletoaffordenoughfortheschoo
