Computer Networking Ebooks

A network, or data network, or IT network is a telecommunications network which allows computers to exchange data. They are most often used in business, education and other organizations that have computers. Networks are popularly referred to as internetworks, although this term is an umbrella term that also includes many types of computer networks that are not commonly thought of as internetworks. Computer networks can be classified based on a wide variety of characteristics such as the transmission medium used to link individual nodes, communications protocols and applications used in the network.
There are two general types of network topology: * Bus - All devices are connected to a single cable. * Star - A central device (hub/switch) connects all other device, acting as a "traffic cop" and providing an easy way of adding or removing devices.
