"Computer Networking Essentials" starts with an introduction to networking concepts. Readers learn computer networking terminology and history, and then dive into the technical concepts involved in sharing data across a computer network.

A computer network is a set of two or more computers with an interconnection which allows communication between the linked computers. Computer networks are essential in facilitating communication within organizations, as well as the entire globe, by means of the Internet. Networks may vary considerably according to size, functionality and topology. In addition, they differ in terms of standards and network models that people use in designing and implementing networks. This book will briefly examine networks and how they help individuals and organizations. According to size, a network may be a Local Area Network (LAN), Metropolitan Area Network (MAN) or Wide Area Network (WAN). LANs cover small geographical locations, for instance, a campus building. MANs cover a metropolitan area such as a town or a city. A WAN covers an extremely large area like a country, region or the entire planet. According to topology, a network may be a bus, star, ring, star-bus, or a token-ring network among others.
