Explanation / Answer
The correct option is c) Data Trasmission Rate(DTR). DTR is the speed with which data can be transmitted from one device to another. Hence, it can be used to directly determine the time taken to transfer an information file in a communication system. The correct option is a)Packet-Switched Networks. These networks utilise 3 key points- use of a decentralized network with multiple paths between any two points, dividing user messages into smaller packets, and delivery by store and forward switching. The correct option is c)33.6 kbps. Analog circuits can conduct only fairly low-speed data communications. In fact, the maximum bit rate over an analog facility is 33.6Kbps when there are analog loops at either end.
