Hub Vs Bridge – what are the main differences?
Are you looking to know the differences between a networking hub and bridge? The following article provides a detailed review of what they are and their major differences in functionality.
When using a network in the large scale, there are devices you may need that may not be required in a home network setup. Two of such devices are hubs and bridges. A hub is small networking device that transmits a network signal to each port from where the signal was received. It is part of the physical layer of networking.There are two types of bus: active hub and passive hubs.
A bridge on the other hand is a network device that connects two different LocalArea Network (LAN) on the same protocol. A bridge is considered more intelligent than a hub since it performs data filtration. The bridge works in the data link layer of the OSI networking model. For large organizations such as schools and work offices, hubs and bridges are used for their respective functions. They are used in conjunction with other networking devices such as switches.

Hub vs. Bridge – How do these devices compare?
Hubs are quite different from bridges in terms of functionality and operations. The following section highlights the features of both devices and how the compare.
Connections and ports
Since hubs and bridges are quite different in operations and use, they vary a lot in their ports and external connections. While hubs are simple and only establish connection between several connected devices, the come with a lot more ports than bridges. A hub works as a connector of different LAN connections from devices. Because of this, hubs may have as little as four ports and as many as 128 ports depending on the brand and price tag. On the other hand, bridges only feature multiple ports divided into two main categories: one incoming and one outgoing ports. The ports are independent ensure that data for one device does not go and is not accessed by another device.
Functionality and use
Hubs and bridges are used over a large scale network connections by large organizations and institutions such as schools. A hub acts as a link between connected devices and does not provide data filtering. Devices such as PCs are connected to the hub through Ethernet cables. The device acts as the main connector of the LAN segments. The main purpose of the hub is to move the packets of data to the connected devices. The lack of data filtering means that when a packet of data is sent by one device or node, it is forwarded to connected devices through the hub. This is also the reason hubs are considered unintelligent networking devices. On the other side, we have the bridge. A bridge is much more secure since it offers data filtering. A bridge is used to connect two LAN of different devices that are operating on the same protocol. It is also used to break down or fragment large LAN into smaller networks. A bridge works by receiving frames of data from the network. It then takes the destination address from the frame and checks for a location to send the frame. In turn, this means that devices or lines connected to a bridge can have their own collision domains. Bridges are therefore considered intelligent networking devices.
Supported devices
Hubs and bridges are versatile in terms of the devices they support. This is because they come with multiple ports. A hub can be connected to other networking devices such as switches, it can also be connected to PCs through the many gigabit Ethernet ports it comes with. A bridge on the other hand comes with two ports that are meant to connect different LANs on the same network protocol. They can be connected to hubs, switches and PCs through the LAN Ethernet ports they come with
Hub vs. Bridge – A comparison Overview
Hub – Overview
A hub is a networking device that provides a simple functionality yet very essential in the operation of a network, especially a large network connection. The main job of this small device is to provide a connection between the multiple devices connected to it. It transmits the network signal to each port except the receiver port. The hub is an important device as devices cannot communicate with each other over a large network without them. Because of this, you will mainly find them being used in institutions such as schools and office buildings. The hub operated on the physical layer of the OSI networking model. This means it falls under the unintelligent category of networking devices. However, the main reason it is referred to as unintelligent is because it does not provide data filtering. For instance, it say four PCs are connected the hub and one of the PCs sends data to the hub, the packet of data would be forwarded to the remaining three connected PCs.
There are also two types of hubs: active and passive hubs. A passive hub only allows for the transmission of electric signals. The active hub on the other hand also provides passage for the electric signals but also boosts and regenerates the signal before it is transmitted to the connected devices. The active hub does not do data processing.

Bridge – Overview
Another essential device that is used over large scale networking is the bridge. It is a small device that allows two different LANs on the same protocol to communicate. In addition, it is also used to break down and fragment large network packets into smaller ones. A bridge works by retrieving the destination address from a received network frame. It uses the destination address to check and find the location where the frame should be sent. Because of this, different connected devices or line have their own collision domains. Today, there are wireless bridges that are used in homes and smaller setups. They work similarly to the wired bridges and do a fantastic job in boosting the network to dead zones in the house. There are three types of bridges: transparent bridge, Source Route Bridge and Translational Bridge.
