Packets
Data Link Layer
tcp is the transport control protocol and ip is the internet protocol. tcp is concerned with guaranteed delivery of packets from source to destination, while ip is the protocol used to actually deliver packets. tcp is located at layer 4 of the osi model, or the transport layer. ip is located at layer 3 of the osi model, or the network layer. check out the video tutorials in the link below.
Network Layer
transport layer of osi model is responsible for end to end delivery of packets over a network

MTU-based fragmentation primarily occurs at the Network Layer (Layer 3) of the OSI model, where IP packets are divided to fit the maximum transmission unit of a network.
