An accessible guide to our digital infrastructure, explaining the basics of operating systems, networks, security, and other topics for the general reader.
Most of us feel at home in front of a computer; we own smartphones, tablets, and laptops; we look things up online and check social media to see what our friends are doing. But we may be a bit fuzzy about how any of this really works. In Bits to Bitcoin, Mark Stuart Day offers an accessible guide to our digital infrastructure, explaining the basics of operating systems, networks, security, and related topics for the general reader. He takes the reader from a single process to multiple processes that interact with each other; he explores processes that fail and processes that overcome failures; and he examines processes that attack each other or defend themselves against attacks.
Day tells us that steps are digital but ramps are analog; that computation is about “doing something with stuff” and that both the “stuff” and the “doing” can be digital. He explains timesharing, deadlock, and thrashing; virtual memory and virtual machines; packets and networks; resources and servers; secret keys and public keys; Moore's law and Thompson's hack. He describes how building in redundancy guards against failure and how endpoints communicate across the Internet. He explains why programs crash or have other bugs, why they are attacked by viruses, and why those problems are hard to fix. Finally, after examining secrets, trust, and cheating, he explains the mechanisms that allow the Bitcoin system to record money transfers accurately while fending off attacks.
商品描述(中文翻譯)
一個易於理解的數位基礎設施指南，為一般讀者解釋作業系統、網路、安全性及其他主題的基本概念。
我們大多數人在電腦前感到自在；我們擁有智慧型手機、平板電腦和筆記型電腦；我們在線上查詢資訊，並查看社交媒體以了解朋友的動態。但我們可能對這一切的運作方式有些模糊。在《Bits to Bitcoin》中，Mark Stuart Day 提供了一個易於理解的數位基礎設施指南，為一般讀者解釋作業系統、網路、安全性及相關主題的基本概念。他帶領讀者從單一過程到多個相互作用的過程；他探討失敗的過程和克服失敗的過程；並檢視相互攻擊或自我防禦的過程。
Day 告訴我們，步驟是數位的，但坡道是類比的；計算是關於「用東西做某事」，而「東西」和「做」都可以是數位的。他解釋了時間共享、死鎖和抖動；虛擬記憶體和虛擬機器；封包和網路；資源和伺服器；私鑰和公鑰；摩爾定律和湯普森的黑客。他描述了如何通過內建冗餘來防範故障，以及端點如何在互聯網上進行通信。他解釋了為什麼程式會崩潰或出現其他錯誤，為什麼它們會受到病毒攻擊，以及為什麼這些問題難以修復。最後，在檢視秘密、信任和作弊之後，他解釋了使比特幣系統能夠準確記錄資金轉移同時抵禦攻擊的機制。
