In the OSI model, data at which layer is packaged into packets?

Explanation

The OSI model is a conceptual framework for understanding network communication. It divides network communication into seven layers, each with specific functions.● Network Layer: The network layer is responsible for routing data packets across networks. It determines the best path for data to travel between source and destination networks. This layer also performs logical addressing, assigning IP addresses to identify devices on the network. In this layer, data is segmented into packets and headers are added containing addressing information for routing.● Data Link Layer: The data link layer is responsible for error detection and correction in data transmission between directly connected devices on a network segment. It ensures reliable data transfer over the physical layer.● Transport Layer: The transport layer provides reliable data transfer services between applications running on different devices. It establishes connections, manages data flow, and ensures in-order delivery of data segments.Session Layer: The session layer establishes, manages, and terminates sessions between communicating applications. It provides mechanisms for data exchange and synchronization between applications
