This print textbook is available for students to rent for their classes. The Pearson print rental program provides students with affordable access to learning materials, so they come to class ready to succeed.

A top-down, layered approach to computer networking.

Unique among computer networking texts, the 8th Edition of the popular Computer Networking: A Top Down Approach builds on the authors’ long tradition of teaching this complex subject through a layered approach in a “top-down manner.” The text works its way from the application layer down toward the physical layer, motivating students by exposing them to important concepts early in their study of networking. Focusing on the Internet and the fundamentally important issues of networking, this text provides an excellent foundation for students in computer science and electrical engineering, without requiring extensive knowledge of programming or mathematics. The 8th Edition has been updated to reflect the most important and exciting recent advances in networking, including the importance of software-defined networking (SDN) and the rapid adoption of 4G/5G networks and the mobile applications they enable.

First Published in 2000. The timing of this book is auspicious in that we can look backwards at the twentieth century as the period of maximum environmental impact by humans in their history, while looking forward to a new era of potential improvement by drawing on and learning from this experience. This book''s purpose, therefore, is to consider how to address education for children to become informed and concerned adults who will be able to understand critically the implications of these choices and act wisely in the wider interests of society and the planet as a whole.

The fourth edition of Teaching Secondary Science has been fully updated and includes a wide range of new material. This invaluable resource offers a new collection of sample lesson plans and includes two new chapters covering effective e-learning and advice on supporting learners with English as a second language. It continues as a comprehensive guide for all aspects of science teaching, with a focus on understanding pupils’ alternative frameworks of belief, the importance of developing or challenging them and the need to enable pupils to take ownership of scientific ideas. This new edition supports all aspects of teaching science in a stimulating environment, enabling pupils to understand their place in the world and look after it.Key features include:Illustrative and engaging lesson plans for use in the classroomHelp for pupils to construct new scientific meaningsM-level support materialsAdvice on teaching ‘difficult ideas’ in biology, chemistry, physics and earth sciencesEducation for sustainable development and understanding climate changeManaging the science classroom and health and safety in the laboratorySupport for talk for learning, and advice on numeracy in scienceNew chapters on e-learning and supporting learners with English as a second languagePresenting an environmentally sustainable, global approach to science teaching, this book emphasises the need to build on or challenge children’s existing ideas so they better understand the world in which they live. Essential reading for all students and practising science teachers, this invaluable book will support those undertaking secondary science PGCE, school-based routes into teaching and those studying at Masters level.
