Why was first packet switching developed?

Packet switching was developed to improve the efficiency and reliability of data transmission over networks. Traditional circuit-switched networks were inefficient for handling bursty data traffic, as they required a dedicated path for the entire duration of a communication session. Packet switching allows data to be broken into smaller packets that can be sent independently across the network, optimizing bandwidth usage and enhancing resilience against network failures. This innovation laid the foundation for modern computer networking and the internet.
