In one general aspect, a computing system includes a cast terminal including a keyboard component and a display component physically coupled to the keyboard component, and a central computing device. The keyboard component includes a first communication module configured to transmit keystroke data over a first wireless network to the central computing device using a first wireless communication protocol. The display component includes a second communication module configured to receive multimedia data over a second wireless network from the central computing device using a second wireless communication protocol. The central computing device includes a third communication module configured to receive the keystroke data from the first wireless network, and a fourth communication module configured to transmit the multimedia data over the second wireless network.
