Which layers does a link-layer switch process?
The link layer...
What layer of OSI model does a computer operate?
All layers.
At which OSI model layers do the application layer or upper layer protocols operate?
Application Presentation Session
What are the three layers that a router must implement to operate?
A router must implement the Physical layer, the Link layer, and the Network layer
What is a switch known as that operates on layer 7?
There are no switches that operate on layer 7 (Application layer) on the OSI Model. Switches are a layer-2 device because they manage and switch frames.
What layers of the OSI model does the NIC operate?
The NIC operates on Layer 2 (Data Link Layer) of the OSI Model.
Which of the OSI layers handle the following. 1.dividing the transmitted bit stream into frames 2.dividing the application data into segments?
Which of the OSI layers handle the following. 1.dividing the transmitted bit stream into frames? Data link layer Which of the OSI layers handle the following: 2.dividing the application data into segments? Transport layer the PDU (Packet Data unit) for layers is as the following - Application, Presentation, and Session layers ==> uses Data - Transport layer ==> uses Segment - Network layer ==> uses Packets - Data link layer ==> uses Frames - Physical layer ==> uses Bits. ....
What type of device is switch?
A Switch is a Layer 2 device as they operate in the data link layer
What devices operate at the session layer of OSI model?
Gateway network device
Which of the following is considered a Layer 2 device?
Switches are generally considered layer 2 devices, but many are capable of operating at layers 3, 4 or higher. Most hubs are amplifying the electrical signal; therefore, they are really repeaters with several ports. Hubs and repeaters are Layer 1 (physical layer) devices.
Devices which are works on osi model 7 layers?
Devices that operate across the OSI model's seven layers include routers, switches, and firewalls. Routers function primarily at Layer 3 (Network) by directing data packets between networks, while switches operate mainly at Layer 2 (Data Link) to facilitate communication within a local area network. Firewalls can work at multiple layers, inspecting traffic and enforcing security policies across Layer 3 and Layer 4 (Transport), and sometimes even higher layers. Additionally, gateways can operate at all layers, translating between different network protocols.
A repeater work at the physical and network layers. a. true b.false?
False - a repeater is a simple layer 1 device. It would not have a need to operate at the network layer.
