While it is true, a net computing refers to a set of devices interconnected with each other from a medium, whereby they exchange information and share resources. For this, it is important that there are two well-defined roles for connected devices, since there must be both a sender and a receiver.
Now, in the great field of computer networks, it is valuable to know different terms, especially when it comes to connecting devices. At this point, comes into play the famous “HUB” or “Concentrators” that they are a piece of hardware capable of connecting network traffic coming from multiple devices.
But, to learn more about what are these devices for and how do they work, like how are they classified in the computer network environment and What aspects to take into account when setting up one in your network; We invite you to read this post. In such a way, you will know how to buy an ideal HUB for your type of network.
What is a hub or hub and what is it used for in a computer network?
Known as “Concentrator”, in Spanish, a HUB is defined as a device through which you can connect several devices to each other in order for them to communicate. That is to say, it serves to interconnect different equipment, such as: smartphones, tablets, computers, laptops, TVs, USBs and SD cards, for example.
Consequently, a HUB or hub presents the ability to create a network of computers connected to each other and even offers the possibility of extend the same from other similar equipment. Since, the hub is an entity that has a certain number of ports and thus, its purpose is based on retrieve the binary data that accesses through a port to emit it to the other inputs.
In this way, it deals with concrete existing network traffic that comes from numerous computers, and then takes care of regenerating the signal for all its ports. This, regardless of what is connected to these ports, because make a “broadcast” which consists of a process of receiving a piece of information and sending it to everyone.
Now, it should be noted that, a HUB is not the same as a switch. Given that, a hub is not able to disagree if the information that passes through itself is directed to one computer or another, because it is only limited to receive it and repeat it. While, a switch or “switch” is the smart version of a HUB and, therefore, manages to create a communication channel to distribute data to each target device, apart from the fact that works in networks with a larger number of machines.
HUB types How are these devices classified?
Among other details, to better understand the operation of hubs in terms of computer networks, it is relevant to know that there are different categories or classifications of such devices.
Which, we mention below and show you what each one is about:
Refers to a hub that only sends the signal to all connected hosts without amplifying it and it does not require electrical power to operate. Therefore, it only serves as a physical connection point and does not have the ability to manipulate or visualize the traffic that crosses it, so it does not increase the signal. Usually, are used to share physical media.
Unlike passive hubs, active hubs are connected to a power source or electrical outlet, as they require electrical energy to amplify the incoming signal, once it is received and before being broadcast to the other ports. Therefore, it is capable of regenerate and retransmit signals in the same way as a repeater. Furthermore, they are also known as “Multiport repeaters”, because they have eight or twelve ports to be able to connect the computers on the network.
As their name implies, they are more advanced hubs that, apart from working as a Active HUB, too have a microprocessor chip and have diagnostic capabilities. Thanks to this, they are completely useful in fault diagnosis. It should be noted that, this type of hubs They are also called “Smart hubs” and, mainly, they are characterized by being much more expensive than active hubs. In addition to this, allow connecting various types of cables.
What should I take into account when choosing the best Hub to mount my network?
To determine what are the key aspects to consider before buying a HUB or hub, first of all, it is essential set the intended use of this computer network device. Well, everything will depend on it to study the available alternatives and know how to choose between them. Once you are clear about the uses you want to give this new device, you can start to focus on certain aspects of great interest to achieve the best hub around your user experience.
Among these aspects, we highlight the following:
- Compatibility: Of course, it is essential to verify that the computer network hub you want to purchase, have compatibility with your other electronic devices. In other words, it can connect with your smartphone, laptop or TV, for example.
- Ticket type: Depending on the types of devices you need to connect, you have to focus on purchasing a hub that manage to adapt to these inputs to take advantage of their operation. Be it LAN, USB, HDMI, Type-C, etc. Otherwise, you won’t be able to use it to connect what you need.
- Variety of ports: On hubs, the more ports you have the greater your capacity. Therefore, as much as possible, try to select a HUB with multiple ports or inputs.
- The price: One of the most important factors to assess before buying a HUB, it is certainly the cost. This, It will vary according to the brand you decide to buy and the ports that it includes. In general, its price fluctuates between 10 and 60 euros.
