Which three of the following devices operate at the data link layer of the OSI Model?

Which three of the following devices operate at the data link layer of the OSI Model?

Hubs operate at Layer 1, or the Physical layer of the OSI model. Which of the following devices operates at the OSI model Layer 2? A switch operates at the OSI model Layer 2 (Data Link layer). It reads the MAC address to make frame forwarding decisions.

Which network device works at the OSI data link layer?

The OSI Model and Networking Protocols Network devices that operate at this layer include Layer 2 switches (switching hubs) and bridges. The data link layer is divided into two sublayers: Logical Link Control (LLC) sublayer provides the logic for the data link.

What is a 3 layer device?

Simply put, a layer 3 switch combines the functionality of a switch and a router. It acts as a switch to connect devices that are on the same subnet or virtual LAN at lightning speeds and has IP routing intelligence built into it to double up as a router.

What are the three OSI layers?

OSI uses three layers — application, presentation and session — to define the functionality of upper layers, while TCP/IP uses only the application layer.

Which devices work in network layer?

A switch can work at either the Data Link layer or the Network layer of the OSI model. A multilayer switch is one that can operate at both layers, which means that it can operate as both a switch and a router. A multilayer switch is a high-performance device that supports the same routing protocols as routers.

Which of the following devices operate at Layer 2?

A Layer 2 switch is a device that operates according to the Layer 2 data communications protocol. A Layer 2 device decides how to forward data based on the MAC address. Ethernet hubs and network switches work at the data link layer, with a switch delivering greater performance than a hub.

Which of the following is Layer 3 device?

According to OSI Layers, Layer 3 is called Network Layer and the device that is used at Layer 3 is Router. Also, there are some Switches which are designed or taught with Layer 3 capabilities or functionalities and are called as Layer 3 Switches and can be used at Layer 3….Answers.

What is a Layer 3 network switch?

Simply to say, a layer 3 switch is a network switch with some router functions. The most important purpose of the layer 3 switch is to speed up the data exchange within a large LAN. The routing function is also used for this purpose. It can accomplish one route and multiple packet forwarding processes.

Which network devices function only at layer 3?

A Layer 3 switch is a high-performance device for network routing. A router works with IP addresses at layer 3 of the model. Layer 3 networks are built to run on on layer 2 networks. In an IP layer 3 network, the IP portion of the datagram has to be read.

What are the three 3 layers of OSI model that make up the application layers of the TCP IP model?

The top three layers of the OSI model: application, presentation, and session map to the application layer of the TCP/IP model.

What network devices operate at OSI Layer 2 and 3?

Additionally, what network devices operate at OSI Layer 2 and what devices operate at OSI Layer 3? Data-link layer: Bridges, Modems, Network cards, 2-layer switches. Network layer: Routers, Brouters, 3-layer switches. Transport layer: Gateways, Firewalls. Session layer: Gateways, Firewalls, PC’s.

What devices are used in the data link layer?

There are several devices which are used in the Data Link Layer; below explain each one – Bridge: Bridge is electronic device that is used in the computer networking and it helps to establish interconnection along with another bridge under similar protocol.

Where does the use of encryption devices occur in the OSI?

The use of encryption devices occurs during the Presentation layer of the OSI Model as it is the responsibility of this layer to encrypt data.

What is the OSI model of networking?

The Open Systems Interconnect Model, abbreviated as OSI Model, is one of the oldest networking models over which many modern protocols are based. There are basically sever different layers which are involved in the OSI Model; Physical, Data Link, Network, Transport, Session, Presentation and Application Layer.
