What is a hub? It is a device of the computing world, which has a great function of being able to connect different equipment in it, there are different commercial brands, which offer the user great advantages, learn about it in this article. types of hub

What is a hub?

A hub is a device known as a hub, which can be connected to different devices, such as smartphones, USB TVs, SD cards and tablets or PCs. types of hub

Due to its ability to connect several devices in it, it is believed that it is a complicated device, but it is simple even more than the well-known switch or a router.

It can be seen that while a switch is creating a communication path to supply information to each equipment, the hub limits the network exclusively to the sending equipment; the switch has the functionality in networks with a great majority of equipment than the hub.

The function of the router is to communicate the devices with remote networks, it has the ability to interconnect many networks, it is an activity that the switch and neither the hub do.

The primary objective of a hub is to transform the connection center within a network, since all the ports are connected, which means that data is shared simultaneously in the devices connected to the hub so that they can be shared. observe from any of these.

Likewise, hubs can be used to connect different elements of a LAN, through its various ports, in such a way that it creates the same network for all the devices that are connected.

A network hub or repeater hub is a device that has the wonderful function of connecting several devices through crossed cables or fiber optics to function as a single network element.

Its operation types of hub

The hubs work in the physical layer, that is to say layer 1, of the OSI model and its activity is like a multi-port repeater; repeater hubs also act as conflict detectors, sending an obstruction signal to all ports in the event that it has detected an abnormality.

These network devices are not complicated at all, and neither do they congest the traffic that passes through their action, any data that accesses through one port is extended to all other ports.

There are certain hubs on the market that have special ports that can be combined in a way that accepts more hubs, simply by joining them with Ethernet cables, although switches may have to be used to prevent some problems in the network.

There are certain hubs that are known as “smart” with the ability to detect difficulties such as large collisions on individual ports, and in addition to partitioning the port, simply by disconnecting it from the shared element.

An intelligent hub has the ability to show the problem easily, by means of the lights that indicate where the fault is, it also offers the advantage that each of the devices in the network can be disconnected to verify where the difficulty is. .

Its utility types of hub

We have mentioned that a USB hub is an expansion device, it is a propagator of the USB ports of a main system, being the case if a laptop has three USB ports, and is connected to a hub, perhaps extending the number of devices or peripherals to be connected, compared to the well-known terminal blocks.

We invite you to know the following article  USB sound card,   with the intention of knowing a little more about technology.

Among its benefits of a USB hub is the synchronization of the connection as well as the disconnection, when it gathers connections, consciously starting the activity in a single process.

Types of hub

In the computer market there are several types of hub that have several ports, most of them can have up to seven ports, however there are some options of 127 ports, let’s see the classification:

Liabilities

It refers to a hub that does not require an external source to power it, because it does not regenerate the signal, it is as if it is part of the cable, the magnitude of the cable must be taken into account. types of hub

This type of passive hub does not have the ability to amplify incoming packet electrical signals, prior to extending outside the network.

Assets

It is the type of hub that has the ability to regenerate the signal and requires an external socket to feed it; Active hubs offer the option of expansion just like a repeater runs, this type of hub does not provide certain extra functions that are really vital for companies.

The smart ones types of hub

This type has the ability to detect faults like collisions or any other cause, and it has the function as an active hub.

Among the variety of hubs, it can be said that they have differences in terms of transfer speed, there is USB 1.0 (up to 12 Mbps); USB 2.0 (up to 480 Mbps) or USB 3.0 (up to 5Gbps).

An important factor to consider is the power supply, the hubs are divided into self-powered or self-powered, those with an external power supply, and those powered by the main equipment bus, known as bus powered.

These have a disadvantage with difference to those that are self-powered, because the 500 milliamperes (mA) of energy contained in each port are fragmented, perhaps certain devices will not work because they need a lot of energy.

Who may be interested in a hub?

Hubs are devices or concentrators that represent an importance in the world of computing, offering their great capacity to adapt to the particular requirements of users, especially since they have different types of ports, and can be different according to the devices. . types of hub

It may happen that a user owns an archaic computer, of course it does not have many USB inputs or it could be that several of them are not working.

The hub represents a good option to solve these cases, because most of them work as a multi-USB port, which also allows consulting the data contained in the USB memory, especially when using the Smartphone and the printer is connected.

Likewise, if the old laptop does not have the memory card slot, in this case the application of a hub will work as a card reader, as well as it can be connected to the television and show slides.

Another of the functions that hubs have is to access the duplication of a screen, especially through its HDMI port, and if one of the monitors you want to install does not have this input, using a hub is the solution.

It is also important to note that hubs can be useful to connect the laptop to a router or modem, being one of the main functions, which means that the user has the opportunity to enjoy the speed of an Ethernet network from the computer. .

So, that a hub is a device that may be of interest to any user who requires at least one additional port, what must be sure is the type of hub that should be used and that it is also compatible with the equipment.

Aspects to consider before purchasing a hub types of hub

Before knowing what to consider when buying a hub, it should be borne in mind that everything will depend on the use that the device is going to have.

Among the main aspects, the value of the device counts, because the price ranges between the brand and the ports they contain, however, they are not very expensive.

Likewise, the variety of ports and capacity must be taken into account, it is vital to know what types of inputs are required, whether they are HDMI, LAN, USB Type-C, USB 3.0, SDHC card, micro SDHC card or another type. types of hub

It is also important to know what is the compatibility of the hub with other electronic devices, you must be sure, because a hub if it cannot be connected to the laptop, or other portable equipment or the television, will not be useful.

Another significant aspect is to know the type of material and design that the hub is composed of, if the intention or need of the user is to take it from one place to another, you must be aware of its size and weight.

Finally, something that is interesting and cannot be overlooked, is the issue of the guarantee and the after-sales service offered by the manufacturer and the shops, if it were the case that it presents a fault of course, you want to have a service effective care.

Recommended hubs

In this segment it is important to mention which are the most recommended hubs that exist at the forefront of the computing world, we will start with:
