The session layer (layer 5)
data-link layer
The Session Layer L5
The Physical Layer
+network layer logical communication between hosts +transport layer: logical communication between processes ex: we have 2 house and one house have 12 room. kids in the houses send letter together. network layer: only send letter between the houses transport layer: it make sure that the letter be sent to right the room in the house.
The speed at which it establish a network connection.
In a virtual circuit network, there is an end-to-end connection in the sense that each router along the path must maintain state for the connection; hence the terminology connection service. In a connection-oriented transport service over a connectionless network layer, such as TCP over IP, the end systems maintain connection state, but the routers have no notion of any connections; hence the terminology connection-oriented service.
There are three layers in between the network layer & application layer on the basis of ISO-OSI refference they are given below 1:Transmition layer 2:Session layer 3:Presentation layer
IGMP
The Physical Layer
TCP is the protocol of network layer, It is connection oriented protocol. UDP is the protocol of network layer, It is connection less protocol.
transport
The Access Layer
manages the data transport between the processes running on each end host
The physical layer - it describes the hardware and the signaling techniques used at the physical connection between the network and the device.

The advantage of using a layer 3 switch is the speed at which it can establish a network connection.
The speed at which it establish a network connection.
its depend on which protocol used in transport layer
In a virtual circuit network, there is an end-to-end connection in the sense that each router along the path must maintain state for the connection; hence the terminology connection service. In a connection-oriented transport service over a connectionless network layer, such as TCP over IP, the end systems maintain connection state, but the routers have no notion of any connections; hence the terminology connection-oriented service.
