38、R，IR中的操作碼部分經(jīng)指令譯碼器ID譯碼，將識(shí)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(hào)，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(jì)算機(jī)硬件系統(tǒng)包括那幾個(gè)部分？答：微型計(jì)算機(jī)的硬件系統(tǒng)包括中央處理單元（CPU）、內(nèi)存儲(chǔ)器、外存儲(chǔ)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(diǎn)與之不同之處？答：ROM通常用來固化存儲(chǔ)一些生產(chǎn)廠家寫入的程序或數(shù)據(jù)，用于啟動(dòng)電腦和控制電腦

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