Focused on fundamental concepts and practical applications, this book provides a strong foundation in the basic principles and terminology of computer networking and internet technology. This thoroughly revised edition introduces the important topics of current interest like Adhoc Networks and Internet of Things (IoT) in Chapter 8 which is suitable for introductory one-semester courses for undergraduate students of computer science and engineering, electronics and telecommunication engineering, information technology, as well as students of computer applications (BCA and MCA). This edition has also focused on the UGC specified Choice Based Credit System (CBCS) curriculum for B.Sc. in Electronics/Electronic Science.
The text begins with an overview of computer networking and a discussion on data communication. Then it proceeds to explain how computer networks such as local area networks (LANs) and wide area networks (WANs) work, and how internetworking is implemented. Besides, the book provides a description of the Internet and TCP/IP protocol. With the prolific growth of networking, ‘network management and security’ has become an increasingly important part of the academic curriculum. This topic has been adequately dealt with in a separate chapter. The practical aspects of networking, listing the essential requirements needed for actually setting up a computer network, are thoroughly explained in the final chapter of the book. An appendix dealing with telephone networking, wireless networking, cellular networking and satellite and telemetry communication has been included to meet the requirements of the students.
