【正文】 , responsible for directing most of the puter system activities based on the instructions provided. As one puter generation has evolved to the next, the physical size of the CPU has often bee smaller and smaller, while its speed and capacity have increased tremendously. Indeed, these changes have resulted in microputers that are small enough to fit on your desk or your lap.2.Microsoft Word printer DBMS(database management system) Spreadsheet disk cell value Microsoft Excel documentWord processor, __Spreadsheet _________, Database are all application software.

Operating systems software defines the ‘personality’ of the puter by specifying the way in which programs are controlled, files are stored and retrieved, and how the system’s hardware ponents are held together. Software written to run on a specific PC operating system can’t run on another. To use PCs effectively, one must understand the capabilities of their operating systems software.個人計算機軟件建立于特定的操作系統(tǒng)和計算機。基于某一特定的PC操作系統(tǒng)編寫的軟件不能用于其他操作系統(tǒng)。3．An application software (also called enduser program) is any program designed to perform a specific function directly for the user or, in some cases, for another application program. Examples of application software include word processors。 Web browsers。 drawing, paint, and image editing programs。應用軟件的例子有：字處理器，數(shù)據(jù)庫程序，網(wǎng)絡瀏覽器，打發(fā)工具，繪圖和圖像編輯程序，通信程序等。計算機專業(yè)英語作業(yè)2第46章作業(yè)一．Vocabulary( 詞匯)(一)．Translate the following words and expressions into Chinese(寫出下列詞組的漢語。 Specification 需求分析和說明 (二)．Fill in the blanks with the corresponding English abbreviations.(根據(jù)漢語寫出相應的英語縮寫。)1．客戶機/服務器 client/server 2．二維的 two dimensional 3．點擊鼠標右鍵 right click 4．調(diào)試程序 debug the program 5．高級語言 highlevel language 6．標準版 standard edition 7．代碼窗口 code window 8．軟件生命周期 software life cycle 9．軟件測試 software testing 10．數(shù)據(jù)流圖 dataflow diagram 二．Tell whether the following statements are true(T) or false(F).(判斷正誤。)（一）．1.
