Which devices works at Layer 2?

Which devices works at Layer 2?

LAYER 2 NETWORKS Devices used on a Layer 2 Ethernet network include network interface cards, hubs, bridges and switches. Ethernet devices use ‘burned in’ MAC addresses to identify each host. These addresses are attached to network interface cards and cannot be changed.

What is Layer 2 device in networking?

A layer 2 device on a computing network will transmit data to a destination according to Media Access Control (MAC) addresses, also known as Ethernet addresses. The data link layer of a multipoint network can establish a connection, segment data into frames, and manages data arrivals.

Is hub a Layer 2 device?

Hubs are basically layer 1 devices without any intelligence and do not separate collision or broadcast domains. Switches are basically layer 2 (MAC addresses) with some intelligence and separate collision domains.

Is bridge a Layer 2 device?

A network bridge is a computer networking device that creates a single, aggregate network from multiple communication networks or network segments. In the OSI model, bridging is performed in the data link layer (layer 2).

What kind of devices are used in data link layer?

Some of the devices used in Data Link layer are, A bridge is a type of computer network device that provides interconnection with other networks that use the same protocol, connecting two different networks together and providing communication between them. Modem stands for MOdulator/DEModulator.

How is communication between devices in Layer 2?

Communication among devices at layer 2 is done via some interconnecting device, which forms connection between each host machine or network devices (router, wireless, etc). Switch is that device which provides interconnection. Switch has ports (physical interface) at which wires from various network devices or host machines connect.

What is the function of a layer 2 switch?

In the above section, we mentioned that a layer 2 switch is a bridge. The function of a network bridge is to join two network segments or divide one network into two separated network segments or LANs.

What are the pros and cons of Layer 2 networking?

So let’s consider their pros and cons: The PROS of using a Layer 2 network: Layer 2 networking tends to be cheaper to set up, and has lower maintenance overheads. Layer 2 networks require no routers, just the right array of network switches. This makes them simpler and easier to understand.
