network layer and data link layer

Answer 2

Answer:

The network layer is a host-to-host OSI layer.

Explanation:

• The Open Sources Interconnection (OSI) is a seven-layered architecture each with unique function but together to transmit date from one user to another across the world.
• The seven layers are – application, presentation, session, transport, network, and data link layer.
• The network layer is a hardware layer that functions as a host-to-host layer to transmit data from one host to another, both in different networks.
• It functions through routing and logical addressing. Routing that selects the data transmission route is implemented through routers.
• Logical addressing places the IP addresses of the sender and receiver in the header.
