This book is for anyone who wants to understand computer programming. You'll learn to program in a language that' s used in millions of smartphones, tablets, and PCs. You'll code along with the book, writing programs to solve real-world problems as you learn the fundamentals of programming using Python 3. You'll learn about design, algorithms, testing, and debugging, and come away with all the tools you need to produce quality code. In this second edition, we've updated almost all the material, incorporating the lessons we've learned over the past five years of teaching Python to people new to programming.You don't need any programming experience to get started. First, you'll get a detailed introduction to Python and to programming. You'll find out exactly what happens when your programs are executed. Through real-world examples, you'll learn how to work with numbers, text, big data sets, and files. Then you'll see how to create and use your own data types.The incremental examples show you the steps and missteps that happen while developing programs, so you know what to expect when you tackle a problem on your own. Inspired by "How to Design Programs" (HtDP), you'll learn a six-step recipe for designing functions, which helps you as you start to learn the concepts--and becomes an integral part of writing programs by the end.As you learn to use the fundamental programming tools in the first half of the book, you'll see how to document and organize your code so that you and other programmers can more easily read and understand it. Beyond the basics, you'll learn how to ensure that your programs are reliable, and how to work with databases, download data from the web automatically, and build user interfaces. Most importantly, you'll learn how to think like a professional programmer.You'll need to download Python 3, available from "python.org". With that download comes IDLE, the editor we use for writing and running Python programs. (If you use Linux, you may need to installPython 3 and IDLE separately.)
If used for a class, the book of 12 chapters contains just about right amount of coverage for a semester or quarter. It balances introductory and fairly advanced subjects on computer networking and cybersecurity to furnish both technical and managerial knowledge. Although the writing is moderately dense, much effort has been placed on explaining sometimes challenging concepts in a manner that readers can follow through with careful readings.
No effort was spared in providing readers with real or quasi hands-on learning experience without necessarily relying on a computer lab. First, each chapter comes with practical exercises questions. In the class setting, they are good as individual or group assignments. Many of them are based on simulated or real cases, and take advantage of actual industry products and systems for a reader to better relate theories to practice. Second, there are a number of information-rich screen shots, figures, and tables in each chapter carefully constructed to enhance visual learning. Readers are encouraged to review each of them carefully to solidify learning.
In addition to the thorough technical details, managerial issues including network planning, design, and management are covered throughout the book from the practitioner s perspective to afford balanced learning. Besides, bearing in mind of the critical importance of cybersecurity in today s computer networks, implications of a networking technology on cybersecurity are discussed whenever appropriate. Lastly, two chapters are dedicated to introduce fundamentals of cybersecurity in terms of threat types and defense techniques. Summary of Updates This edition has several improvements over the previous one: With the rise of Internet of Things, a section is introduced (Chapter 1). The measures available to strengthen the security of Ethernet switches are expanded (Chapter 3). A section is newly created to provide a high-level understanding of the border gateway protocol (Chapter 6). The explanation of the data VLAN is expanded (Chapter 7). With the rapid progress in WiFi standards, Chapter 8 is updated throughout (Chapter 8). The explanation of Metro-Ethernet is replaced by Carrier-Ethernet reflecting technology advancement (Chapter 9). The cellular network section is added as a wireless WAN technology (Chapter 9). The explanation of WAN topologies (9.4.2) is dropped to avoid duplication (Chapter 9) The explanation of IPv6 is updated (Chapter 10). The firewall and DMZ section is expanded significantly to introduce different practical approaches in setting up the firewall (Chapter 12).
Introduction to Computer Science Using Python: A Computational Problem-Solving Focus,recommended by Guido van Rossum, the creator of Python (âThis is not your average Python bookâ¦I think this book is a great text for anyone teaching CS1â). With a focus on computational problem solving from Chapter 1, this text provides numerous hands-on exercises and examples, each chapter ending with a significant-size program demonstrating the step-by-step process of program development, testing, and debugging. A final chapter includes the history of computing, starting with Charles Babbage, containing over 65 historical images. An end-of-book Python 3 Programmersâ Reference is also included for quick lookup of Python details. Extensive instructor materials are provided for those adopting for classroom use, including an instructorsâ manual, over 1,000 well-developed slides covering all fundamental topics of each chapter, source code, and test bank.Â
