Transport Layer:
Transport layer is used for transferring the data or messages between the nodes and the devices. The data is sent in the form of blocks or segments. It is used to establish the end-to-end connection between the source and the destination.
Network Layer:
Network layer is provides the path in which the data packets are transferred from the source to the destination. It also helps in converting the logical or IP address to physical or Media Access Control (MAC) address.
Internet Protocol:
Internet protocol is a process or protocol in which data is transferred between the computer systems through internet. Each computer system has its own IP address to send or receive the required data. It consists of five different layers namely, application layer, transport layer, network layer, link layer and physical layer.
Datagram:
- In networking, a datagram is a transferring unit which is used to transfer the data from a source to the destination and it doesn’t provide guaranteed service.
- It includes fragmentation process which is defined as the division of the data packet into small one when the data packets are larger than the maximum length of a particular system.
