Network bridge or network cables (i.e ethernet cables)
transport layer does this
Yes, that is one of its primary uses.
Network Interface card
Polling in satellite networks is electronic signally between satellites to see which one is going to send data. It also requires a receiver that is polled to see if it is ready to transmit data.
Besides the cables themselves, each device needs a NIC interface card, and if the computers are on separate networks you need a router. Within a network you would also need a hub, switch, or bridge device.
An access time is the time interval between the issuing of a request to send data from or write data to a storage device and the completion of this action.
Radio frequency signals.
circuit switching.
