計算機(jī)科學(xué)導(dǎo)論

內(nèi)容概要

隨著計算機(jī)應(yīng)用的普及，“計算機(jī)科學(xué)導(dǎo)論”課程不再是教授學(xué)生使用字處理器、數(shù)據(jù)庫、電子表格、演示軟件和電子郵件了，也不是只限于諸如Web頁面設(shè)計和交互式圖形的“娛樂”應(yīng)用，而是還應(yīng)包含諸如算法、硬件設(shè)計、計算機(jī)組織結(jié)構(gòu)、系統(tǒng)軟件、語言模型、計算理論以及計算機(jī)社會與倫理問題等知識。對這些核心知識的介紹，將向?qū)W生展示整個計算機(jī)領(lǐng)域的豐富和華美。它不僅使得學(xué)生可以高效地使用計算機(jī)和軟件，而且還可以鑒賞計算機(jī)和軟件的創(chuàng)建和實現(xiàn)背后的基本思想。本書就是針對“計算機(jī)科學(xué)導(dǎo)論”課的這種改革而編寫的。本書全面地介紹了該學(xué)科的內(nèi)容，無需讀者有計算機(jī)科學(xué)、程序設(shè)計或數(shù)學(xué)等背景知識。本書不僅適合用作計算機(jī)及相關(guān)專業(yè)學(xué)生的課程，也非常適合用作高中計算機(jī)科學(xué)課程的教材。

章節(jié)摘錄

插圖：The discussions in Level 1 assume that our algorithms are executed bysomething called a "computing agent," an abstract concept for any entity thatcan effectively carry out the instructions in our solution. However, in Level 2（Chapters 4-5）, "The Hardware World," we want our algorithms to be executedby "real" computers to produce "real" results. Thus begins our discussion ofhardware, logic design, and computer organization. The initial discussionintroduces the basic building blocks of computer systems——binary numbers,Boolean logic, gates, and circuits. It then shows how these elementary conceptsare used to construct a real computer using the classic Von Neumann architec-ture, including processors, memory, buses, and input/output. It presents a typ-ical machine language instruction set and explains how the algorithms of Level1 can be represented in machine language and run on the Von Neumann hard-ware of Level 2, conceptually tying together these two areas. It ends with a dis-cussion of important new directions in hardware design——multicore andmassively parallel machines.By the end of Level 2 students have been introduced to some basic con-cepts in logic design and computer organization, and they understand andappreciate the enormous complexity of these areas. This complexity is themotivation for Level 3 （Chapters 6-8）, "The Virtual Machine." This sectiondescribes how system software produces a more friendly, user-orientedproblem-solving environment that hides many of the ugly hardware detailsjust described. Level 3 looks at the same problem discussed in Level 2,encoding and executing an algorithm, but shows how much easier this is ina virtual environment containing software tools like editors, translators, andloaders. This section also discusses the services and responsibilities of oper-ating systems and how operating systems have evolved. It investigates oneof the most important virtual environments in current use——a network ofcomputers. It shows how systems such as the Ethernet, Internet, and theWeb are created from computers linked together via transmission media and communications software.
