Which layer is absent in broadcast network?
network layer
Which network layer protocol is responsible for routing packets on the network?
The network layer is the layer that is responsible for routing packets on the network. This is the layer in which Internet protocol operates. In the seven layer OSI model, the network layer is the third layer from the bottom.
How does a network administrator use the osi model to isolate a network problem?
the network administrator uses the OSI model to troubleshoot network problem by verifying functionality of each layer, in many cases, troubleshooting the network problem requires the network administrator to isolate at what layer the network problem occurs. network administrators often describe networking problems by layer number, for example, a physical link problem is described as a layer 1 problem; a router problem is a layer 3.
What layer programs access the network?
Network Layer
Which is an important factor when choosing a Layer 2 protocol?
-The geographic scope of the network -The physical layer implementation -The number of hosts to be interconnected
Hich three factors should be considered when implementing a Layer 2 protocol in a network?
the geographic scope of the network the physical layer implementation the number of hosts to be interconnected
Which layer is the network support layer?
Physical, Data link and Network layers make the Network Support layers.
What is layered network?
A layered network, or a network layer, is the set up of how data is sent over a network. Each layer has it's own responsibility by either capturing the data or routing it to a computer on the network.
Which layers of the OSI Reference Model provides for inter network connectivity?
Network Layer
What is specified by the network number in an IP address?
The network number in an IP address is that portion of the IP address that matches the subnet mask. For instance, if the IP address is 10.11.12.13 and the subnet mask is 255.255.0.0, then the network number is 10.11.0.0. If the subnet mask is 255.255.255.0, then the network number is 10.11.12.0. The network layer (layer 2 in the OSI model) in the TCP/IP protocol stack uses the network number to determine if the destination address is directly reachable, or if the frame needs to be routed through the default gateway.

What is the highest layer of the OSI model used by router?
Router works in Network Layer of OSI model
