Explanation
The layer that handles packet fragmentation and reassembly in the Open System Interconnection (OSI) reference model is the network layer. The network layer is the third layer of the OSI model, and it is responsible for routing and forwarding packets across different networks. The network layer also performs packet fragmentation and reassembly, which are processes that divide a large packet into smaller fragments to fit the maximum transmission unit (MTU) of the underlying network, and reassemble the fragments back into the original packet at the destination. Packet fragmentation and reassembly can improve the efficiency and reliability of data transmission, as well as avoid congestion and errors.
