37、B）字節(jié)C）字D)字符12.存儲器中的每個存儲單元都被賦予一個唯一的序號，稱為（D）A）序號B）下標(biāo)C）編號D)地址第三章第三章微型計算機硬件基礎(chǔ)知識微型計算機硬件基礎(chǔ)知識習(xí)題習(xí)題3一、思考題1簡述計算機的系統(tǒng)組成及工作原理。答：一個完整的微型計算機系統(tǒng)由硬件系統(tǒng)和軟件系統(tǒng)兩大部分組成。計算機的工作原理是：計算機啟動工作后，首先將待執(zhí)行程序在內(nèi)存中的起始地址送入程序計數(shù)器PC，控制器根據(jù)PC中的地址，從存儲器中取出指令，送入指令寄存器I

38、R，IR中的操作碼部分經(jīng)指令譯碼器ID譯碼，將識別出的操作性質(zhì)送入操作命令產(chǎn)生部件，再由操作命令產(chǎn)生部件按一定順序發(fā)出一系列控制命令信號，送到各有關(guān)部件，使各部件完成指令所規(guī)定的操作。2計算機硬件系統(tǒng)包括那幾個部分？答：微型計算機的硬件系統(tǒng)包括中央處理單元（CPU）、內(nèi)存儲器、外存儲器和輸入輸出設(shè)備等。6RAM和ROM的功能是什么？比較它們的特點與之不同之處？答：ROM通常用來固化存儲一些生產(chǎn)廠家寫入的程序或數(shù)據(jù)，用于啟動電腦和控制電腦

39、的工作方式。而RAM則用來存取各種動態(tài)的輸入輸出數(shù)據(jù)、中間計算結(jié)果以及與外部存儲器交換的數(shù)據(jù)和暫存數(shù)據(jù)。ROM是只讀存儲器，斷電后其保存的數(shù)據(jù)不會丟失。RAM是隨機存儲器，斷電后其保存的數(shù)據(jù)會丟失。二、選擇題1.下面有關(guān)計算機的敘述中，（B)是正確的。A）計算機的主機包括CPU.內(nèi)存儲器和硬盤三部分B）計算機程序必須裝載到內(nèi)存中才能執(zhí)行C）計算機必須有硬盤才能工作D）計算機鍵盤上字母鍵的排列方式是隨機的2.PentiumIII800微機
