Datagram packet switching:

Detailed explanation-1: -Circuit switching is a switching method in which a dedicated communication path in physical form between two nodes within a network is established, maintained and terminated for each communication session. In traditional landlines, circuit switching was used; fiber optic lines were set up for each telephone call.
Detailed explanation-2: -Advantages of packet switching over circuit switching: Data packets are able to find the destination without the use of a dedicated channel. Reduces lost data packets because packet switching allows for resending of packets. More cost-effective since there is no need for a dedicated channel for voice or data traffic.
Detailed explanation-3: -Packet Switching transmits data across digital networks by breaking it down into blocks or packets for more efficient transfer using various network devices.
Detailed explanation-4: -Circuit switching is a type of network configuration in which a physical path is obtained and dedicated to a single connection between two endpoints in the network for the duration of a dedicated connection. Ordinary voice phone service uses circuit switching.
