Why don't we learn about what are hubs. All You Need to Know About Hubs - A Deep Dive Into Their Purpose and FunctionalityImagine a network of computers or devices that are connected and can communicate with each other. How do they all stay connected, and enable communication between themselves? That's where hubs come to the rescue. In this article, we'll discuss what hubs are, how they work, and their importance in networking.What are Hubs?Hubs are devices that are used to connect multiple Ethernet devices to form a network. They serve as common connection points for devices in a network, allowing them to communicate with each other. In the simplest terms, hubs amplify and forward all incoming network traffic received over a single connection to all other ports.How do Hubs Work?Hubs are simple devices that work on the physical layer of network communication. They operate on the OSI layer 1, which means they only know how to forward data based on physical information, i.e., the signal received from the incoming device. They do not have any intelligence, and all incoming data is forwarded to all other devices in the network.When a device sends a message to another device in the network, the message is first passed through the hub, which forwards it to all the other devices connected to the hub. The recipient device then extracts the message, and the rest discard the message, as it is not meant for them.Types of Hubs:There are mainly two types of hubs, Active Hubs and Passive Hubs.Active Hubs:Active Hubs, also known as powered hubs, use their internal power supply to amplify the incoming data signals, enabling data to travel longer distances without losing quality. They are capable of cleaning and boosting the incoming signal through amplification before forwarding it to connected devices. Active Hubs are favored for high-performance networks where devices need to communicate over longer distances with minimal signal degradation.Passive Hubs:Passive Hubs, on the other hand, have no internal power supply and do not amplify the signals received. They just transfer data between devices connected to them. Passive hubs work well in small networks where all devices are located in close proximity and communicate over short distances.Importance of Hubs in Networking:Hubs form the foundation of networking, and without them, it would be impossible to connect multiple devices in a network. They enable communication between devices and ensure that data is properly transmitted over the network.In a world where most devices are network-connected, hubs have become an essential component. They enable the sharing of information and resources, making it possible for businesses and individuals to communicate and collaborate seamlessly.Conclusion:In summary, hubs play an important role in enabling communication between devices in a network. They come in different types - active and passive, and have their use-cases depending on the network size and requirement. As network technologies continue to evolve, hubs will continue to play an integral role in networking.
