  1. A -explanation …packets can use different paths where as circuits connected via one path. Dedicated circuits like a T1 circuit uses one path. VoIP phones for example uses different paths…packets are sent and via IP it uses the best effort delivery while maximizing QoS. VoIP is a packet switching configuration. The old POTS or Plain Old Telephone uses a circuit switching network and uses that circuit as long as the connection remains between two subscribers, for example. Hope my answer is correct.
