connectionless communication

Connectionless communication is a method where data is sent from one device to another without establishing a dedicated connection beforehand. Think of it like mailing a letter—you send a message without confirming the recipient is ready or available beforehand. Each message travels independently, and there's no guarantee it will arrive or arrive in order. This approach is often faster and more efficient for simple or sporadic data exchanges, as it doesn’t require establishing or maintaining a persistent connection between devices. Examples include the internet’s User Datagram Protocol (UDP).
