Networks that do not use wires are known as wireless networks and are commonly associated with the telecommunications industry. Data is transmitted using electromagnetic waves, usually radio waves, and remote information transmission systems which organise the data.
Computer networking deals with the communication between two computers or devices. A computer network is essentially a collection of computers that can communicate between each other and send and receive data. The computer networking industry was born out of the telecommunications disciple as it relies heavily on the theory and practical applications of technology and principles used in the telecoms industry.

A Ethernet/Network hub is a small and simple device which is generally used to connect various fibre or twisted pair opticEthernet devices together, this is in order to make them work as a single network segment. These hubs do not generally manage most of the traffic which comes through them due to the device being a fairly unsophisticated broadcast device. One of these hubs is fairly inexpensive and many network hubs bought today will support the Ethernetstandard, whereas other types such at the USB hubs are also available. Though Ethernet is the most common type traditionally used in home networking.
