現(xiàn)代的微處理器可以在一個集成電路的封裝中，集成100萬個以上的晶體管，而該硅片的大小僅約1平方英寸（1英寸=2.54厘米）。微處理器是所有個人電腦的心臟。如果再加上存儲器和電源，那么對于一臺計算機所需要的所有部件（除了外圍設備）就齊備了。當今最流行的微處理器系列是摩托羅拉（Motorola）公司的680x0系列。它支持蘋果（apple）公司的Macintosh機型和英特爾(Intel)公司的80x86xilie，它是所有IBMPC兼容機及PS/2計算機的核心。2．擴展詞匯。diskfull磁盤滿了disknotready磁盤未準備好terminal終端deviceunavailable設備不可用devicefault設備故障invalid無效的parameter參數(shù)error錯誤version版本NotesReadingComprehensionWindows

3.WhatisthedifferencebetweenWindowsandthetraditionalfilingcabinet?譯文鍵盤

當你想將信息輸入電腦，只需要在鍵盤上敲打字母和數(shù)字。在所有輸入設備中，鍵盤是最常使用的。沒有鼠標我們?nèi)阅苡面I盤工作，因為所有鼠標的工作都可以用鍵盤來完成。然而沒有鍵盤就不可能完成任務。因此作為電腦初學者，第一步就是學會使用鍵盤。

通常來說，鍵盤分為六大區(qū)和四個附加鍵。字母與數(shù)字鍵區(qū)占據(jù)了鍵盤的絕大部分，位于鍵盤的左部。一共是26個字母和10個數(shù)字。剩余的絕大部分是控制鍵。在上方我們可以看到功能鍵，它們分別執(zhí)行不同的任務。數(shù)字鍵區(qū)在鍵盤右部。在字母和數(shù)字鍵之間是特殊功能鍵和方向鍵。

如果你想打字很快僅僅對鍵盤有個大概了解還不夠。有些人電腦很在行因為他們會盲打，就是說他們打字很快。盲打也叫按指法打，指的是不看鍵盤用手指輸入文本。聽起來很有趣，事實上，學會盲打需要時間，你需要不斷地學習與練習。

另一種經(jīng)常用到的硬件是軟盤。它可移動，可以方便隨身攜帶。你可以用軟盤從電腦上拷貝文件，然后隨身攜帶。然而它的容量相對很小，今天已逐漸被U盤——一種更小但是容量很大的移動硬盤——所代替。譯文Windows

Windows因為形狀像矩形盒子所以起名為Windows。這些
