    Every year, tens of thousands of people embark towards taking the exam via private study, Cisco Academy courses, or online training. The sad truth is most students quit along the way, and for those few who actually do attempt it, only 50% pass. All that time, effort, and money wasted! If there are so many manuals, CBT courses, lab simulators, exam engines, and study resources out there, then what goes wrong? This is the question Cisco trainer Paul Browning wanted to get to the bottom of. After interviewing thousands of students, he discovered that most people quit because they are simply overwhelmed with the sheer volume of material they need to digest and, of course, the large number of hands-on skills they need to be able to demonstrate in the exam. Add to that the day-to-day stresses of commuting to work, bringing up a family, and the distraction of everyday problems and challenges; it's no wonder people quit. This is where Cisco CCNA in 60 Days can help. Devised by two industry experts and countless Cisco students just like you, the 60-day programme breaks down every exam requirement into a daily study task. All you need to do is open the book at the relevant day (from 1 to 60), read the theory, and complete the lab. Every lesson is reviewed several times in the form of exam questions, review sessions, a handy exam cram guide, and, of course, hands-on labs for you to follow. You can choose to take the CCENT after the first 30 days and the ICND2 after the next 30 days, or you can take the CCNA after 60 days of study. Here is what is included in your study guide: 60 daily study tasks Full explanations of theory Real-world tips and advice Over 47 hands-on labs, plus 15 bonus CCENT and ICND2 labs CCENT and ICND2 cram guides Bonus VLSM guide Motivational goal-setting guide Downloadable videos Author Paul Browning is a former police officer who used his CCNA qualification to help him make a career change to IT. He worked for Cisco in the UK for a while, and then went on to start his own Cisco training company, which he ran for 8 years before moving into online Cisco training. He is the author of several Cisco study guides. He has also created the online Cisco certification training sites, including www.howtonetwork.net and www.in60days.net. Technical author Farai Tafa used to work in a shoe shop but decided he wanted more out of life, so he began to study for his Cisco exams. He is now a dual CCIE and one of the leading Cisco consultants in the US. He currently designs, installs, and troubleshoots networks for large companies.

    Routing TCP/IP, Volume II, provides you with the expertise necessary to understand and implement Border Gateway Protocol Version 4 (BGP-4), multicast routing, Network Address Translation (NAT), IPv6, and effective router management techniques. Jeff Doyle's practical approach, easy-to-read format, and comprehensive topic coverage make this book an instant classic and a must-have addition to any network professional's library. Routing TCP/IP, Volume II, expands upon the central theme of Volume I: scalability and management of network growth. Volume II moves beyond the interior gateway protocols covered in Volume I to examine both inter-autonomous system routing and more exotic routing issues such as multicasting and IPv6. This second volume follows the same informational structure used effectively in Volume I: discussing the topic fundamentals, following up with a series of configuration examples designed to show the concept in a real-world environment, and relying on tested troubleshooting measures to resolve any problems that might arise. This book helps you accomplish more than earning the highly valued CCIE number after your name; it also helps you develop the knowledge and skills that are essential to perform your job at an expert level. Whether you are pursuing CCIE certification, need to review for your CCIE recertification exam, or are just looking for expert-level advice on advanced routing issues, Routing TCP/IP, Volume II, helps you understand foundation concepts and apply best practice techniques for effective network growth and management.

    This text is user-focused and has been highly updated including topics, pictures and examples. The Williams text contains less theory and more application to engage students who might be more familiar with technology. Continually published and updated for over 15 years, Using Information Technology was the first text to foresee and define the impact of digital convergence--the fusion of computers and communications. It was also the first text to acknowledge the new priorities imposed by the Internet and World Wide Web and bring discussion of them from late in the course to the beginning. Today, it is directed toward the "Always On" generation that is at ease with digital technology--comfortable with iPhones, MySpace, Facebook, Twitter, Wikipedia, and the blogosphere--but not always savvy about its processes, possibilities, and liabilities. This 8th edition continues to address the two most significant challenges that instructors face in teaching this course: -Trying to make the course interesting and challenging, and -Trying to teach to students with a variety of computer backgrounds. In addition, this text correlates with Simnet Online for full integration of resources within the Computing Concepts course.

    On Twitter, word can spread faster than wildfire. Companies no longer have the option of ignoring the conversation. Unlike other hot social media spaces, "Twitterville" is dominated by professionals, not students. And despite its size, it still feels like a small town. Twitter allows people to interact much the way they do face-to-face, honestly and authentically. One minute, you re com- plaining about the weather with local friends, the next, you re talking shop with a colleague based halfway across the globe. No matter where you re from or what you do for a living, you will find conversations on Twitter that are valuable. Despite the millions of people joining the site, you ll quickly find the ones who can make a difference to you. Social media writer Shel Israel shares revealing stories of "Twitterville" residents, from CEOs to the student who became the first to report the devastation of the Szechuan earthquake; from visionaries trying to raise money for a cause to citizen journalists who outshine traditional media companies. Israel introduces you to trailblazers such as: . Frank Eliason, who used Twitter to reverse Comcast s blemished customer service reputation . Bill Fergus, who was on the team at Henry Ford Medical Center during the first live tweeted surgery . Scott Monty, social media officer for Ford, who held off a mob of misinformed Ranger fans and averted a PR crisis . Connie Reece, who used Twitter to raise tens of thousands of dollars for cancer patients in need . The Coffee Groundz, a Houston-area coffee shop that uses Twitter to pack the tables (and fight off Starbucks) "Twitterville" features many true stories as dramatic as these. But it also recounts those of ordinary businesspeople who use Twitter to get closer to their customers. And it explains how global neighborhoods will make geography increasingly irrelevant. It even explains why people sometimes really do care what you had for lunch."

    In this one-of-a-kind text, author V. Anton Spraul breaks down the ways that programmers solve problems and teaches you what other introductory books often ignore: how to Think Like a Programmer. Each chapter tackles a single programming concept, like classes, pointers, and recursion, and open-ended exercises throughout challenge you to apply your knowledge. You'll also learn how to:Split problems into discrete components to make them easier to solve Make the most of code reuse with functions, classes, and libraries Pick the perfect data structure for a particular job Master more advanced programming tools like recursion and dynamic memory Organize your thoughts and develop strategies to tackle particular types of problems Although the book's examples are written in C++, the creative problem-solving concepts they illustrate go beyond any particular language; in fact, they often reach outside the realm of computer science. As the most skillful programmers know, writing great code is a creative art—and the first step in creating your masterpiece is learning to Think Like a Programmer.
