Detailed explanation-1: -Transport layers (Layer 4) work transparently within the layers above to deliver and receive data without errors. The send side breaks application messages into segments (packets) and passes them on to the network layer (Layer 3).
Detailed explanation-2: -The transport layer is the fourth layer of the OSI model which is responsible for the process to process delivery of data. The network layer divides the data received from the transport layer in the form of packets. The network layer provides two ways of communication namely-connection-oriented and connection-less.
Detailed explanation-3: -The network layer uses logical addresses to communicate from host to host in different networks. Furthermore, it adds the IP address of the sender and the receiver in each packet so that each sent packet can reach its designated destination. Network Layer also provides the services for routing and switching.
