What else can I help you with?
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 encapsulation in layered communications?
Encapsulation in layered communications refers to the process of wrapping data with protocol information as it moves down the layers of the OSI or TCP/IP model. Each layer adds its own header (and sometimes trailer) to the data from the layer above, creating a "packet" at the transport layer, a "frame" at the data link layer, and so on. This method allows each layer to operate independently while ensuring that the necessary information is available for proper data transmission and reception. Ultimately, encapsulation facilitates modular communication by allowing different networking protocols to work together seamlessly.
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.
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.
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 layer of the OSI model does NAT operate?
Layer 3
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
Wireless access point operate in what layer in OSI model?
it works in layer 2
