Computer

This is the latest information letting you know, TCP / IP Network Layer. The net work layer is called IP (internet Protocol). since this is a network layer, it is responsible for sending data between end systems of different networks. IP accomplishes this by using data link layer such as Ethernet to transmit data between systems on the same network ,often the system Ethernet delivers the data to is router that can now forward the data to another network.
each end system has a unique address  . some systems have multiple network interfaces and therefore multiple IP addresses. The IP layer in each end system uses a data link layer to transmit and receive IP packets.


Thanks
