Essentials of Computer Networking

A digital telecommunications network that facilitates the sharing of data among computing devices through data links connecting nodes is called a computer network. Network nodes are the devices within the network that are responsible for originating, routing, and terminating data. Nodes can include hosts like phones, servers, and personal computers, as well as networking hardware such as switches and routers. Various transmission media like radio waves, optical fiber, and electrical cable can be used to link devices and form computer networks. Networks are distinguished by their organizational objectives and physical capabilities. Examples of different network types include wide area networks, local area networks, and nanoscale networks. This book is a valuable compilation of topics, ranging from the basic to the most complex principles and applications in the field of computer networking. It explores all the important aspects of this field in the present day scenario. This textbook will serve as a reference to a broad spectrum of readers.
