Answer: No, UDP is not a two-way connection, it is a connectionless protocol that allows for two-way communication without establishing a persistent connection.
Connectionless Nature
UDP is inherently connectionless, meaning it does not establish a dedicated end-to-end connection before sending data.
Bidirectional Communication
Despite its connectionless design, UDP supports bidirectional communication. This means that two parties can exchange data both ways, but each exchange is independent.
No Session Management
Unlike connection-oriented protocols, UDP does not manage sessions or maintain state information about the exchanges. Each UDP packet is sent independently of others.
Application Responsibility
It falls upon the application using UDP to implement any necessary logic to manage the flow of data, ensure data integrity, or establish a logical “connection” or sequence of communication.
Conclusion
While UDP itself does not create a two-way connection in the traditional sense of establishing a continuous link between two endpoints, it supports two-way communication through independent, stateless datagrams.
