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.

Host:

• A host is a computer system or any device connected to other system or device in a network to exchange the data.
• A network host provides required information or data resources, services, applications and many others to other users present in the network.
• It can be a network node related to the network address.

Datagrams:

• 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.
