At what a layer of the OSI reference model does a hub switch or router operate?

At what a layer of the OSI reference model does a hub switch or router operate?

data link layer
A hub works on the physical layer (Layer 1) of OSI model while Switch works on the data link layer (Layer 2). Switch is more efficient than the hub. A switch can join multiple computers within one LAN, and a hub just connects multiple Ethernet devices together as a single segment.

Which layer of the TCP IP model does a hub operate within?

Physical Layer
Physical Layer – Physical layer of TCP/IP model is responsible for physical connectivity of two devices. Some of the devices used in Physical layers are, Hubs: Hubs are devices commonly used to connect segments of a LAN.

Which layer of the OSI model will I find hubs?

A hub works at the physical layer (layer 1) of the OSI model. A repeater hub also participates in collision detection, forwarding a jam signal to all ports if it detects a collision.

In which layer of the Open System Interconnection OSI does Frame Relay occur?

As a WAN protocol, Frame Relay is most commonly implemented at Layer 2 (data link layer) of the Open Systems Interconnection (OSI) seven layer model.

Which of the following devices operate at the data link layer of the Open Systems Interconnection OSI model?

Which three of the following devices operate at the Data Link Layer of the OSI model? Explanation: Network interface cards (NICs), bridges, and switches all operate at the OSI Data Link layer.

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.

What layer of the OSI Open System Interconnect 7 layer model does IPv4 and IPv6 reside?

The network layer describes routing, which is moving data from a system on one LAN to a system on another. IP addresses and routers exist at layer 3, where protocols include IPv4 and IPv6, among others.

What is 7 layer of OSI Model?

The OSI Model Defined In the OSI reference model, the communications between a computing system are split into seven different abstraction layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application.

What is the Open System Interconnection model?

OSI (Open System Interconnection) model is the reference model that describes how different model layers communicate over the network. ISO is an organization and OSI is the model. Therefore, this model consists of seven different layers. OSI layers which are the backbone of OSI model.

Which layer of the OSI model does not include the transmission media?

The lower boundary of the physical layer of the Open Systems Interconnection (OSI) model is the physical connector attached to the transmission media. Physical layer of the Open Systems Interconnection (OSI) model does not include the transmission media.

What is the position of Session layer of the OSI model?

The position of Session Layer of the Seven Layered Open Systems Interconnection (OSI) model is between Transport Layer and the Presentation Layer. Session layer is the fifth layer of seven layered Open Systems Interconnection (OSI) Model.

What is the presentation layer of the interconnection model?

The presentation layer is the sixth layer of the open system interconnection reference model. This layer is concerned with syntax and semantics of the information exchanged between two systems. The presentation layer is the layer which manages the rules and set of protocols to transfer data over the channel.
