Book Description
The Internet continues to grow at a very rapid rate. Together with this growth there is an accompanying growth of the technologies on which it is based. These technologies make use of TCP/IP as their foundation. To start to make sense of all these interrelated systems it is important that today's computer user be aware of the technologies on which the Internet is based. This book introduces those technologies and is aimed at the Internet user who wishes to understand the technologies on which much of today's business and recreational computing is based. As such, the intention of this book is to give a succinct overview of 'how it all works' rather than provide a comprehensive reference work. This book will help you quickly obtain an understanding of the technological principles behind the Internet/communications revolution in both your working and recreational lives, and: · provides a thorough understanding of intranets, extranets and the Internet · explains all about: how e-mail delivers mail the domain name service how the Internet finds computers the problems facing network designers the basics of computer security issues some new technologies such as WAP, Bluetooth, UMTS and NAPSTER · Shows you how your office or home network really works.

Pages : 337
Book Description
AN INSTANT NEW YORK TIMES BESTSELLER!! Named a Best Book of 2019 by TIME, Amazon, and The Washington Post A Wired Must-Read Book of Summer “Gretchen McCulloch is the internet’s favorite linguist, and this book is essential reading. Reading her work is like suddenly being able to see the matrix.” —Jonny Sun, author of everyone's a aliebn when ur a aliebn too Because Internet is for anyone who's ever puzzled over how to punctuate a text message or wondered where memes come from. It's the perfect book for understanding how the internet is changing the English language, why that's a good thing, and what our online interactions reveal about who we are. Language is humanity's most spectacular open-source project, and the internet is making our language change faster and in more interesting ways than ever before. Internet conversations are structured by the shape of our apps and platforms, from the grammar of status updates to the protocols of comments and @replies. Linguistically inventive online communities spread new slang and jargon with dizzying speed. What's more, social media is a vast laboratory of unedited, unfiltered words where we can watch language evolve in real time. Even the most absurd-looking slang has genuine patterns behind it. Internet linguist Gretchen McCulloch explores the deep forces that shape human language and influence the way we communicate with one another. She explains how your first social internet experience influences whether you prefer "LOL" or "lol," why ~sparkly tildes~ succeeded where centuries of proposals for irony punctuation had failed, what emoji have in common with physical gestures, and how the artfully disarrayed language of animal memes like lolcats and doggo made them more likely to spread.

Understanding Computers, Smartphones and the Internet
Author: Ernie Dainow
Publisher: Ernie Dainow
ISBN: 0995214409
Category : Education
Languages : en
Pages : 126
Book Description
Most introductory books about computers are long, detailed technical books such as those used in a computer science course or else tutorials that provide instructions on how to operate a computer with little description of what happens inside the machine. This book fits in the large gap between these two extremes. It is for people who would like to understand how computers work, without having to learn a lot of technical details. Only the most important things about computers are covered. There is no math except some simple arithmetic. The only prerequisite is knowing how to use a web browser. As an alternative or adjunct to reading the book, you can watch a series of short videos by going to youtube.com and searching for “Understanding Computers, Smartphones and the Internet”. Only current day technology is covered. People who are interested in learning about how computers evolved from the earliest machines can read the companion book “A Concise History of Computers, Smartphones and the Internet”. While originally intended for people who are not in the computer field, this book is also useful for those taking a coding course or an introductory computer science course. Even people already in the computer field will find things of interest in this book.

The Internet of Us: Knowing More and Understanding Less in the Age of Big Data
Author: Michael P. Lynch
Publisher: W. W. Norton & Company
ISBN: 1631491865
Category : Philosophy
Languages : en
Pages : 256
Book Description
"An intelligent book that struggles honestly with important questions: Is the net turning us into passive knowers? Is it degrading our ability to reason? What can we do about this?" —David Weinberger, Los Angeles Review of Books We used to say "seeing is believing"; now, googling is believing. With 24/7 access to nearly all of the world’s information at our fingertips, we no longer trek to the library or the encyclopedia shelf in search of answers. We just open our browsers, type in a few keywords and wait for the information to come to us. Now firmly established as a pioneering work of modern philosophy, The Internet of Us has helped revolutionize our understanding of what it means to be human in the digital age. Indeed, demonstrating that knowledge based on reason plays an essential role in society and that there is more to “knowing” than just acquiring information, leading philosopher Michael P. Lynch shows how our digital way of life makes us value some ways of processing information over others, and thus risks distorting the greatest traits of mankind. Charting a path from Plato’s cave to Google Glass, the result is a necessary guide on how to navigate the philosophical quagmire that is the "Internet of Things."

Networking and Online Games
Author: Grenville Armitage
Publisher: John Wiley & Sons
ISBN: 0470030461
Category : Technology & Engineering
Languages : en
Pages : 232
Book Description
The computer game industry is clearly growing in the direction of multiplayer, online games. Understanding the demands of games on IP (Internet Protocol) networks is essential for ISP (Internet Service Provider) engineers to develop appropriate IP services. Correspondingly, knowledge of the underlying network's capabilities is vital for game developers. Networking and Online Games concisely draws together and illustrates the overlapping and interacting technical concerns of these sectors. The text explains the principles behind modern multiplayer communication systems and the techniques underlying contemporary networked games. The traffic patterns that modern games impose on networks, and how network performance and service level limitations impact on game designers and player experiences, are covered in-depth, giving the reader the knowledge necessary to develop better gaming products and network services. Examples of real-world multiplayer online games illustrate the theory throughout. Networking and Online Games: Provides a comprehensive, cutting-edge guide to the development and service provision needs of online, networked games. Contrasts the considerations of ISPs (e.g. predicting traffic loads) with those of game developers (e.g. sources of lag/jitter), clarifying coinciding requirements. Explains how different technologies such as cable, ADSL (Asymmetric Digital Subscriber Line) and wireless, etc., affect online game-play experience, and how different game styles impose varying traffic dynamics and requirements on the network. Discusses future directions brought by emerging technologies such as UMTS (Universal Mobile Telephone Service), GPRS (General Packet Radio Service), Wireless LANs, IP service Quality, and NAPT/NAT (Network Address Port Translation/Network Address Translation) Illustrates the concepts using high-level examples of existing multiplayer online games (such as Quake III Arena, Wolfenstein Enemy Territory, and Half-Life 2). Networking and Online Games will be an invaluable resource for games developers, engineers and technicians at Internet Service Providers, as well as advanced undergraduate and graduate students in Electrical Engineering, Computer Science and Multimedia Engineering.

The Flip Side of Free
Author: Michael Kende
Publisher: MIT Press
ISBN: 0262362856
Category : Business & Economics
Languages : en
Pages : 267
Book Description
Why "free" comes at a price: the costs of free internet services in terms of privacy, cybersecurity, and the growing market power of technology giants. The upside of the internet is free Wi-Fi at Starbucks, Facetime over long distances, and nearly unlimited data for downloading or streaming. The downside is that our data goes to companies that use it to make money, our financial information is exposed to hackers, and the market power of technology companies continues to increase. In The Flip Side of Free, Michael Kende shows that free internet comes at a price. We're beginning to realize this. Our all-purpose techno-caveat is "I love my smart speaker...but"--is it really tracking everything I do? listening to everything I say?
