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.
a communication device
Digital Data is data that is stored in binary, and a Digital Device is any device that works with binary data
Initiate data exchanges May upload data to serves
The telephone call has been transmitted over data networks/internet.

The Internet
A router is a networking device that forwards data on a network.
A router is a device that forwards data packets along networks. A router is connected to at least two networks, commonly two LANs or WANs or a LAN and its ISP's network. Routers are located at gateways, the places where two or more networks connect, and are the critical device that keeps data flowing between networks and keeps the networks connected to the Internet.
A router is a device that routes all traffic to and from your network. A router functions by forwarding packets of data between computer networks.
Specialized Device for exchanging data amongst class based Networks & Subnetted (multiple parts of one network) is Router.

packet switching technology which uses short fixed length
The speed of data transfer (in KBps or MBps) between computers connected in these networks (Internet, LAN or WAN) will be faster than normal networks. Hence they are called High speed networks. Here high speed Swithing facilitates high speed data transmission.
one such device is the spectacle or reading glasses.
If the message is going between two different networks then it must be routed (this includes different subnets of the same network as well). Routing is done by a router as the device.
