Correct responses for wired networks will indicate that in most configurations, each node (computers and peripherals) in a network is connected to a server. Nodes are connected to the server using network cables attached to network interface cards (NIC). NICs enable the nodes to communicate with each other and with the server. Nodes with the proper permissions are able to access the network's resources. These permissions are granted by the network administrator, who sets up and maintains an organization's network and makes sure it runs efficiently. The network administrator is assisted by the NOS that monitors network use and manages its resources.

Correct responses for wired networks will indicate that two most common connections are infrared and microwave. Networks using infrared transmit data using light emitting diodes (LEDs) or lasers. Microwave transmissions can be terrestrial (by land), using microwave towers to transmit signals from one place to another. Signals can also be transmitted using satellites. Satellites receive data from network nodes and transmit it to other nodes requesting the information.
