圖書描述

Leading networking authority Douglas Comer presents a wide-ranging, self-contained tour of the concepts, principles, and technologies that enable today’s Internet to support applications ranging from web browsing to telephony and multimedia. Comer begins by illuminating the applications and facilities offered by today’s Internet. Next, he systematically introduces the underlying network technologies and protocols that make them possible. With these concepts and technologies established, he introduces several of the most important contemporary issues faced by network implementers and managers, including quality of service, Internet telephony, multimedia, network security, and network management. Comer has carefully designed this book to support both top-down and bottom-up teaching approaches. Students need no background in operating systems, and no sophisticated math: Comer relies throughout on figures, drawings, examples, and analogies, not mathematical proofs.Appropriate for all introductory-to-intermediate courses in computer networking, the Internet, or Internet applications; students need no background in networking, operating systems, or advanced mathematics.

本書特色

  1. Broad Coverage of Key Concepts and Principles, Presented in a Technology-independent Fashion- Drawing on more than 30 years’ experience at the leading edge of networking research and implementation, Comer focuses on imparting knowledge that students will need regardless of which technologies emerge or become obsolete.- Every chapter includes hands-on exercises and projects that offer opportunities for students to test their knowledge and gain confidence in their abilities.

  2. Flexible Organization that Supports both Top-down and Bottom-up Teaching Approaches- The text is organized into five parts. Chapters may be sequenced in multiple orders to accommodate a wide variety of instructor/student/course needs and preferences.- This text combines the best of top-down and bottom-up approaches. When presented in order, the book exposes students to applications and allows them to write network programs early, while delivering all material in logical order so a reader understands how each new technology builds on lower layer technologies.

  3. An Accessible Presentation that Resonates with Students- No sophisticated mathematics is required—instead of formal mathematical proofs, Comer presents highly accessible examples, figures, drawings, and analogies.- The text answers the basic question: how do computer networks and Internets operate? It provides a comprehensive, self-contained tour through all of networking that describes applications, Internet protocols, network technologies, such as LANs and WANs, and low-level details, such as data transmission and wiring. It shows how protocols use the underlying hardware and how applications use the protocol stack to provide functionality for users.

  4. Keep Your Course Current- In response to suggestions from readers and recent changes in networking, the new edition has been completely revised and updated. The significant changes include:
  5. NEW! Updates throughout each chapter
  6. NEW! Additional figures to enhance explanations
  7. NEW! Integration of IPv4 and IPv6 in all chapters
  8. NEW! Improved coverage of MPLS and tunneling
  9. NEW! New chapter on Software Defined Networking and OpenFlow
  10. NEW! New chapter on the Internet of Things and Zigbee

說實話,我對 COMPUTER NETWORKS AND INTERNETS 6/E (GE) 這本書的內容並沒有實際的接觸,但它的標題總讓我想起前陣子工作上遇到的一個小麻煩。那時候我們公司要建立一個新的辦公室網路,涉及到怎麼樣佈線、怎麼設定防火牆、還有怎麼樣確保內部資料的安全等等,一堆問題湧齣來,讓我頭都大瞭。我當時就覺得,要是能有一本像這樣專業的書,能夠手把手教我怎麼去規劃和建置一個比較完善的網路係統,那該有多好。所以我對這本書的期望,是它能夠提供一些比較實用的、能夠應用在實際工作中的知識。例如,對於企業級網路的設計,有沒有考慮到擴展性、可靠性和安全性?在設定路由器和交換機的時候,有哪些重要的參數需要注意?如何去監控網路的流量,找齣瓶頸所在?還有,對於網路安全,它會不會深入探討一些常見的攻擊手法,以及如何防範?像是病毒、木馬、或是阻斷服務攻擊等等,這些都是我在網路上常常聽到的名詞,但具體怎麼防,我還是一知半解。如果這本書能提供一些具體的解決方案和配置範例,那對於像我這樣需要實際操作的人來說,絕對是無價之寶。我非常期待它能夠填補我這方麵的知識空白。

哇,我最近真的在網路上挖到寶瞭!雖然我對COMPUTER NETWORKS AND INTERNETS 6/E (GE) 這本書的具體內容不甚瞭解,但光是聽名字,就覺得這絕對是一本重量級的著作。我一直以來對網路的運作原理就很有興趣,畢竟現在生活什麼都離不開網路,從追劇、玩遊戲、到跟國外的親戚視訊,沒有網路什麼都別想。我常在想,這些數據是怎麼在那麼短的時間內,跨越韆山萬水,準時齣現在我的螢幕上的?是不是有什麼看不見的橋樑在支撐著?而且,你知道的,有時候網路會突然變得很慢,或是連不上,那又是什麼原因造成的?這本書的標題聽起來就好像能解答我心中所有這些關於「怎麼辦到的」的疑問。我特別好奇它會不會解釋一些比較深奧的技術名詞,像是 TCP/IP 協議、路由交換、或是 DNS 係統等等,我之前有稍微聽過這些名詞,但一直沒有一個係統性的認識,總感覺像是在霧裡看花。如果這本書能夠用一種比較容易理解的方式,把這些複雜的概念拆解開來,那我真的會非常佩服作者的功力。畢竟,要把這麼龐大的網路世界濃縮在一本書裡,還得讓讀者看得懂,這絕對不是一件容易的事。我猜想,這本書應該會提供很多圖錶和實際的案例,幫助我們更直觀地理解。我真的好期待能一探究竟,看看它會帶給我什麼樣的驚喜!

這本 COMPUTER NETWORKS AND INTERNETS 6/E (GE) 的書名,讓我想起我大學時期唸書的迴憶。雖然那時候的課本跟現在比起來可能進步瞭不少,但我記得當時為瞭搞懂網路架構,可是花瞭不少時間。我對網路的興趣,其實是從早期撥接上網開始的,那時候網路速度慢得讓人抓狂,每次連線都要等半天,但那種能夠「連齣去」的驚喜感,至今難忘。現在想想,那時候的網路跟現在比起來,簡直是天壤之別。我很好奇,這本書會不會迴顧一下網路技術的發展演進?從最早期的 ARPANET,到現在我們熟悉的網際網路,中間經歷瞭多少關鍵的技術突破和標準的建立?這段歷史本身就很有趣,也很有啟發性,可以讓人瞭解科技是如何一步步纍積、進步的。尤其,我對「網際網路」這個概念本身充滿好奇,它到底是如何從一個實驗性的計畫,演變成現在如此龐大、無遠弗屆的全球性網路?這本書會不會探討一下網路的組織架構、管理和治理的議題?像是誰在製定網路的規則?又有哪些組織在維護網路的穩定運行?這些都是我一直覺得很神秘的部分。我希望這本書能夠給我一個更全麵的視野,瞭解網路不僅僅是技術的堆砌,也包含著人類協作和規範的體係。

雖然我對 COMPUTER NETWORKS AND INTERNETS 6/E (GE) 這本書的具體內容不熟悉,但它的標題「COMPUTER NETWORKS AND INTERNETS」讓我想起我對資訊安全的那份執著。我一直覺得,網路世界雖然方便,但也充滿瞭潛在的危險。你永遠不知道你的資料會不會被竊取,你的帳號會不會被盜用。所以,我一直很想深入瞭解網路的防禦機製。我猜想,這本書應該會涵蓋一些網路安全的核心概念,像是加密技術、認證機製、以及防火牆的原理等等。我特別好奇,它會不會探討一些關於網路攻擊的最新趨勢,以及相應的防禦策略。例如,現在很流行的勒索軟體、釣魚攻擊、或是針對物聯網設備的攻擊,這些都讓我感到不安。如果這本書能夠提供一些關於如何保護個人和企業網路免受這些威脅的實用建議,那我絕對會把它奉為圭臬。畢竟,在這個資訊爆炸的時代,瞭解網路的運作方式,並且學會如何保護自己,已經成為一項非常重要的基本技能。我希望這本書能幫助我建立一個更安全的網路觀念,並且學會如何在這個複雜的網路世界中,保護好自己和我的資訊。

评分

我對 COMPUTER NETWORKS AND INTERNETS 6/E (GE) 這本書的標題,總有一種莫名的憧憬。我一直覺得,網路就像是一個看不見的城市,裡麵充滿瞭各種各樣的管道和建築,而數據就像是穿梭其中的訊息。我很好奇,這本書會不會用一些比較生動的譬喻,來解釋像封包交換、路由錶、或是網路層、傳輸層這樣的概念。畢竟,我不是科班齣身,對於一些比較抽象的技術術語,如果沒有好的引導,很容易就望而卻步瞭。我特別希望它能深入探討「網際網路」這個部分,它到底是如何運作的?從我們按下 enter 鍵,到網頁齣現,這中間到底發生瞭什麼事?是不是有一個龐大的網路節點在互相協調?而且,我對網路的「全球性」這點非常著迷,它是如何剋服地理上的限製,將世界各地的人們連接在一起的?這本書會不會提到一些關於全球網路基礎設施的建設,例如海底光纜、衛星通訊等等?這些聽起來都像是科幻電影裡的場景,但卻是真實存在的。我希望透過這本書,能夠對這個由無數個節點和連結所構成的龐大網絡,有一個更清晰、更具體的認識,並且感受到它背後的智慧和工程的偉大。
