What is switch hub and bridge?

The key difference between hubs, switches and bridges is that hubs operate at Layer 1 of the OSI model, while bridges and switches work with MAC addresses at Layer 2. Hubs broadcast incoming traffic on all ports, whereas bridges and switches only route traffic towards their addressed destinations.

What is hub and bridge in networking?

1. Hub is network device which is used for connecting number of devices. Bridge is also a network device which is used to connect two different LAN working on same protocol.

What is difference between hub and switch network devices?

Hub and Switch are both network connecting devices. Hub works at physical layer and is responsible to transmit the signal to port to respond where the signal was received whereas Switch enable connection setting and terminating based on need. Switch works in Data Link Layer. …

What is bridge networking device?

A network bridge is a computer networking device that creates a single, aggregate network from multiple communication networks or network segments. Routing allows multiple networks to communicate independently and yet remain separate, whereas bridging connects two separate networks as if they were a single network.

Are bridges still used in networks?

Bridges as a product no longer exist due to how the market evolved. Typically the products specifically called bridges were used in hubbed environments to separate the collision domain or to bridge two network media types together (for example, Ethernet and token ring).

Why hub is not an intelligent device?

A Hub is not an intelligent device, it forwards the incoming messages to other devices without checking for any errors or processing it. It does not maintain any address table for connected devices. It only knows that a device is connected to one of its ports. A hub is connected in limited network size.

What is a bridge switch?

A Bridge is a device that connects two LANs and controls data flow between them. A Switch is a networking device that learns which machine is connected to its port by using the device’s IP Address. Bridges divide collision domain into two parts. Switches are used to connect the work stations or computer systems.

Why switch is intelligent than hub?

The reason switches are known as intelligent hubs is because they build address table in hardware to keep track of different hardware addresses and the port to which each hardware address is associated. The reason why they are compared to hubs because a switch, when started fresh, acts just like a hub.

Why did the hub replace with switches?

The main advantage of a switch over a hub is that it can allow multiple simultaneous packet deliveries from different sources to different receivers.

When would you use a network bridge?

Bridges connects two or more different LANs that has a similar protocol and provides communication between the devices (nodes) in them. By joining multiple LANs, bridges help in multiplying the network capacity of a single LAN. Since they operate at data link layer, they transmit data as data frames.
