Application Layer: This single layer maps to the Application, Presentation, and Session layers of the OSI model.
Some protocols that operate at this layer include HTTP, SMTP, and DNS.
Transport Layer: This layer maps to the Transport layer of the OSI model..
How is the network layer used?
The network layer has two main functions.
One is breaking up segments into network packets, and reassembling the packets on the receiving end.
The other is routing packets by discovering the best path across a physical network..
What is layering in computer network?
Use of Layered architecture in computer network provides with the feature of modularity and distinct interfaces.
Layered architecture ensures independence between layers, by offering services to higher layers from the lower layers and without specifying how this services are implemented..
What is the network layer in computer network notes?
The "network layer" is the part of the Internet communications process where these connections occur, by sending packets of data back and forth between different networks.
In the 7-layer OSI model (see below), the network layer is layer 3..
Why do we need network layer?
The network Layer is the third layer in the OSI model of computer networks.
Its main function is to transfer network packets from the source to the destination.
It is involved both the source host and the destination host..
