Detailed explanation-1: -Anything that has to do with inter-network connections takes place at the network layer. This includes setting up the routes for data packets to take, checking to see if a server in another network is up and running, and addressing and receiving IP packets from other networks.
Detailed explanation-2: -The Internet Layer of the TCP/IP model aligns with the Layer 3 (Network) layer of the OSI model. This is where IP addresses and routing live. When data is transmitted from a node on one LAN to a node on a different LAN, the Internet Layer is used.
Detailed explanation-3: -In a process called encapsulation, the network layer adds IP header information, such as the IP address of the source (sending) and destination (receiving) hosts.
Detailed explanation-4: -Layer 3 is the Network or Internet layer. When transmitting data, this layer adds a header containing the source and destination IP addresses to the to the data received from the Transport layer. The packet it creates will then be forwarded to the MAC or Data Link layer.
Detailed explanation-5: -Layer 3 (Network): This layer determines how data is sent to the receiving device. It’s responsible for packet forwarding, routing, and addressing.
