The digital communications network which facilitates the sharing of resources between nodes is termed as a telecommunication network. The process of sharing resources and data between two computers is called computer networking. The connections between them can be established using both cable media and wireless media. Some of the cable media which are used in computer networking are fiber-optic cables and twisted pair cables. A few of the other components of computer networks are generally classified on the basis of their bandwidth, network size, transmission medium and organizational intent. There are various applications and services which depend on computer networking such as World Wide Web, email, fax machines, shared use of printers, etc. This book provides comprehensive insights into the field of computer networking. It elucidates the concepts and innovative models around prospective developments with respect to this field. Coherent flow of topics, student-friendly language and extensive use of examples make this book an invaluable source of knowledge.
