Which osi layer is responsible for the mechanical connection to the network?
The Physical Layer
Difference between transport and network 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.
What is the advantage of using a layer 3 switch in the core of a campus network?
The speed at which it establish a network connection.
In the text the term connection oriented service is used to describe a transport layer service and connection service for a network layer service Why the subtle shades in terminology?
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.
The layer lies between the network layer and the application layer?
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
Operates at the network layer and manages multicasting?
IGMP
Which layer of the OSI model sets up a virtual connection between the communications devices on a network?
transport

Difference TCP and UDP?
TCP is the protocol of network layer, It is connection oriented protocol. UDP is the protocol of network layer, It is connection less protocol.
Which network design layer provides connection point for end user devices to the network?
The Access Layer
What happens to the transport layer PDU as the packet moves through the network?
manages the data transport between the processes running on each end host
What layer of the OSI model defines the rules for accessing and using the physical layer?
The physical layer - it describes the hardware and the signaling techniques used at the physical connection between the network and the device.

What layer is divided into two layers?
The OSI model's data link layer is divided into two sublayers: the Logical Link Control (LLC) and the Media Access Control (MAC) layers. The LLC layer manages communication between devices on a network, while the MAC layer controls access to the physical network medium.
What is the advantage of using a layer 3 switch in the core of a campus network?
The speed at which it establish a network connection.
What is the advantage of using a layer 3 switches in the core of a campus network?
The advantage of using a layer 3 switch is the speed at which it can establish a network connection.
Which OSI layer establishes maintains and terminates the connection with the destination?
The OSI layer responsible for establishing, maintaining, and terminating connections with the destination is the Session Layer, which is the fifth layer of the OSI model. It manages sessions between applications, ensuring that data exchange occurs smoothly and efficiently. This layer provides mechanisms for controlling the dialog and synchronization between communication parties.
