What is the LAN bridges and internet switches?
Bridges and switches operate at the same OSI layer - layer 2. That means they switch packets based on the destination MAC address. A switch is sometimes called a multi-port bridge.A bridge has 2 ports, whereas a switch can have many more than that.
Which layers of the OSI model are involved in data encapsulation?
none
What is the most common method for illustrating the operations of a networking stack?
The OSI Model
What OSI layer is responsible for establishing a temporary communication session between two applications and ensuring that transmitted data can be reassembled in proper sequence?
The application layer.
Which OSI layer does error handling take place?
The data link layer (2nd layer), the network layer (3rd layer) and the transport layer (4th layer) each handle their own specific errors, which should prevent errors in both directions. Any untrapped errors will result in a corrupt transmission which may or may not be handled by the appropriate endpoint, dependant upon the protocol.
Connectivity devices such as hubs and repeaters operate at which layer?
Hubs and repeaters operate at the Physical Layer of the OSI Model. The Physical Layer is the first layer of the OSI Model.
Switches operate at layer and Hubs operate at layer of OSI model?
Hubs are a physical layer (layer 1) device; most switches operate at the Data Link layer (Layer 2) of the OSI model.
What layer of the OSI model does NAT operate?
Layer 3
Devices found in each OSI model?
1. Repeaters (Operate at the OSI Physical Layer).2. Bridges (Operate at the OSI Data Link Layer).3. Routers {and Brouters} (Operate at the OSI Network Layer).
You want to use the OSI reference model to troubleshoot a repeater Which OSI layer will you focus on?
Repeaters operate at the physical layer of the OSI model.
What layers of the OSI model does the NIC operate?
The NIC operates on Layer 2 (Data Link Layer) of the OSI Model.
What is the highest layer of the OSI model used by router?
Router works in Network Layer of OSI model
A non routable protocol does not operate in which layer of the OSI model?
Network Layer
What layer of the osi model does a LMI operate at?
Layer 2 - Data Link
What layer of OSI model does a computer operate?
All layers.
Which layer of the OSI model do VoIP signaling protocols operate in?
Layer 5 - Session layer
What layer of the osi model is odbc and sql?
