Explanation
The Network layer (Layer 3) of the OSI model uses a connectionless protocol for packet delivery. The most common protocol at this layer is IP (Internet Protocol), which is connectionless. It sends packets without establishing a dedicated connection between the sender and receiver, meaning there is no guaranteed delivery or error recovery at this layer - those responsibilities are handled by higher layers, such as the Transport layer.
