A basic network as shown above involves a server which allows access to files, printing, and communication to anyone on the network such as a client. Clients only request services. When the computer converts something into digital information it is called digitizing. After transformed into bits it can travel across the network if there is enough bandwidth. Thy wire that connects one computer to another computer is called a cable medium indicated by the black lines above. A wireless media may be used instead of a cable media. Both types are called transmission media. The computers have to follow a certain protocol to transmit and receive data.
