The Hubs enable devices to communicate and share data by acting as central connecting points inside a computer network. Regardless of the destination, data signals are transmitted to all connected devices by hubs operating at the physical layer of the OSI model. In this article, we will closely examine the network hub, explaining what it is, its many kinds of hubs, its functions, and how they differ from other networking devices like switches.
A Network Hub Is…
A networking device known as a hub acts as the primary point of connection for a LAN. Its main purpose is to collect data signals from linked devices and send them out to all linked devices, irrespective of who is supposed to receive them. In the Open Systems Interconnection (OSI) model, hubs transmit raw data at the physical layer (Layer 1) and do not perform any processing or intelligence on that data.
Various Types of Hub In a Computer Network
Active Hub
An external power source is necessary to operate an active hub, also called a powered hub. It transfers the data over greater distances without signal deterioration since it amplifies and regenerates incoming signals. Active hubs are great for increasing network connectivity because they accommodate more ports.
Passive Hub
There is no need to connect an external power source to a passive hub, also called an unpowered hub. Without signal amplification or regeneration, it only establishes a physical link between devices. The number of ports a passive hub can support is smaller, and the transmission distance is also limited.
Wireless Networking Hub
A wireless networking hub, also called or known as a Wi-Fi hub, works the same as a network hub. It connects all the devices in a Local Area Network (LAN) without the hassle of cables. It allows multiple devices, like smartphones, computers, and tablets, to communicate with each other and access the internet seamlessly. Essentially, one can say it is the wireless meeting ground for all wireless devices.
Our Opinions on Hubs
There are benefits and drawbacks to using hubs, like every networking device.
A hub’s benefits
- Quick Setup: Hubs are user-friendly since they are easy to install and don’t require much configuring.
- Cost-Friendly: Hubs are more affordable than other networking equipment, such as switches or routers.
- Broadcasting: Hubs can be helpful when broadcasting is necessary. Such as video streaming, because they disseminate incoming data to all connected devices.
Restrictions associated with hub usage
- Congestion: As the number of devices connected to a network grows, its performance can degrade due to the hub’s data transmission to all of them.
- Concerning Security: It is easier for unauthorized users to intercept data transmitted across the network because hubs do not have built-in security mechanisms.
- Domain Collision: Every device is part of the same collision domain in a hub-based network. Data loss and retransmission may ensue in the event of a collision that occurs when two devices transmit data at the same time.
Do You Know How Stackable Hubs Function?
To function, hubs take data signals from linked devices and rebroadcast them to every other device in the network. The hub is responsible for instantly broadcasting any data received by any connected device. The hub does not filter or process the data in this type of broadcasting, called “store-and-forward” transmission.
So, What Exactly Is a Hub Good For?
Hardware devices, known as hubs, allow numerous devices to link to a single network. All devices linked to it can communicate with each other since it acts as a hub. In a network configuration, a hub serves multiple purposes, such as:
Extending an Existing Network: Network hubs are perfect for connecting more devices to an existing network. They add numerous devices to a network without the hassle and expense of running more cables.
Sharing Data: A network hub allows all linked devices to exchange data. This is handy when numerous people require access to the same data or files.
Management Made Easier: A hub can make network management easier by concentrating traffic on one network area. Because of this, network administrators can keep tabs on everything happening on the network without ever having to leave their desks.
Affordable: A network hub is usually cheaper than a switch or router for small networks. This is because switches and routers are often intended for usage in more extensive networks with more intricate requirements.
Low Latency: The latency, or time it takes for a signal to move from one device to another, is something hubs provide efficiently. Video streaming and teleconferencing are two examples of applications that benefit greatly from their ability to transmit data in real time.

Playing high-definition material at lightning speed is a breeze thanks to the HDMI connector, which can handle resolutions up to 4K@30Hz.
Can You Tell Me How a Hub Differs From a Switch?
The main distinction between hubs and switches is how they manage data transfer inside a network.
A network hub is an OSI device that acts as a relay for incoming data, broadcasting it to all connected devices at the model’s physical layer (Layer 1). The data is replicated and forwarded to all other devices on the network when it is sent to a hub from a device. With this broadcasting method, devices compete for the network’s bandwidth in a shared collision domain, which can cause congestion and slowdowns.
On the other hand, switches function at the OSI model’s data link layer (Layer 2). Using Media Access Control (MAC) addresses, it manages data transport smartly. The destination media access control (MAC) address is one determinant a switch uses to send data from one device to another selectively.
Conclusion
In conclusion, knowing what a network hub is and how it works helps us to appreciate its many applications; hubs offer remarkable network scalability, stability, and flexibility. Hubs are becoming a standard feature of many networks as the number of connected devices in homes and offices continues to rise. If you want to keep track of all the connected devices in your home, a network hub could be the way to go. Any business, no matter how big or small, can profit from a hub because of all the extra features and ease of use. Make sure you know if you need a Direct Macro hub or a switch when thinking about networking equipment so you can use all the features they offer!
