What is a network hub and how does it work?


A network hub is a very basic networking device, using it to connect multiple computers with other networking devices. Now for your information, let me tell you that Hubs are such common network infrastructure devices which are used LAN is for connectivity, while switches are now replacing hubs. Hubs function according to the central connection point of LANs.

At the same time, people have many doubts about Hubs. So today I thought that why should you people be provided complete information about what are Hubs so that you can know how this networking device works and what are its advantages and disadvantages. Then without delay let’s start.

What is Hub – What is Hub in Hindi

A Hub is a device that splits a network connection into multiple computers. It is like a distribution center. when one The computer requests information from a single network or from a specific computer, then it sends that request to the hub via a cable.

What is Network Hub?

Then the hub receives that request and transmits it to the entire network. Every computer in that network then has to know that this Data broadcast happens whether it is for them or not.

But right now these hubs are very less in vogue and they are being replaced by more advanced communication devices such as Switches and Routers.

This hub is basically a multiport repeater. This hub is used to connect multiple wires which come from different branches, for example the connector which is used. star topology and it is used to connect different stations.

Hubs cannot filter data, so data packets are sent to all connected devices. In other words, then all the hosts that are connected to the hub have a collision domain one (1).

Apart from this, they also do not have their own intelligence so that they can find the best path for the data packets, so that in the end their wastage and inefficiencies also.

Types of Hubs – Types of Hubs in Hindi

When it comes to the types of hubs, they can be divided into three broad categories on technical bases. They are passive hubs, active hubs and intelligent hubs.

Passive Hub

Passive Hubs are those hubs that collect wiring from the nodes and power supply of the Active Hub. These hubs relay signals to the network without cleaning and boosting them, and they cannot be used to extend the distance between nodes.

As its name is passive, in the same way, it only broadcasts signals through the input port, while it sends them through the output port.

At the same time, it does not do anything to regenerate or process signals because it only functions like a connector in a topology to connect many wires.

Active Hub

These are called hubs which have their own power supply and can clean, boost and relay signals on their own in the network. It serves as both a repeater and a wiring center. They are used to extend the maximum distance between nodes.

This active hub works more than a connector, while it regenerates data bits to ensure whether the signals are strong or not. Another name for an active hub is a multiport repeater.

Along with actively participating in a network, it also behaves like an interface. It can also easily monitor data before forwarding them and sometimes it also improves signals before forwarding them to other connections.

Having such a feature, network problems can be easily troubleshooted.

Intelligent Hub

An intelligent hub can very easily perform all the tasks that a passive hub and active hub perform, and together they help in effectively managing the network resources so that the performance of the network is highly efficient.

Through an intelligent hub, the actual location of the problem can be identified so that it can be eliminated from the root. It is very adaptable to different technologies and it can be used without much change in its configuration.

This intelligent hub also performs many different functions such as bridging, routing, switching And network management.

what is network hub

A network hub is a networking device that is connected to multiple peripherals in a network and helps them to function as a single segment, while unlike a switch or router, it broadcasts data across each connection. It does not route them to a specific device.

Network hubs also have different speeds, which are referred to as the network data rate or called bandwidth. Where earlier older network hubs only 10 Mbps speeds Whereas today’s hubs offer speeds of up to 100 Mbps.

In today’s larger networks, it is necessary that a dual speed network hub is used, and it comes in both 10 and 100 Mbps which provides connection points to computers and printers.

Therefore, before purchasing a hub, pay attention to how many devices are going to be connected with that network hub.

What are the features of Network Hub?

Do you know the maximum number of computers that can be connected to one big hub? If we talk about a USB hub, then we can connect 127 devices to it and 32 to the network hub. Let us now know what are the features of Network Hub.

  • It operates in half duplex mode.
  • It is available in 4 to 24 port sizes.
  • In this, the hosts are responsible if there is any collision detection and retransmission of packets.
  • They are mainly of three types: – Active hub, passive hub and intelligent hub.

How does the hub work?

If we look in the true sense then a network hub is more of a A variable port is a repeater, and not just a common The link is for the cluster of computers. Its very common operation is that whatever information it receives, it forwards it to all the PC terminals which are attached.

The major disadvantage in this is that there is repetition of data in it, so that unnecessary data traffic is sent to the network. Therefore, the data is sent in bulk without identifying its destination.

Whereas if we compare it with switches then it works more efficiently, switches control the flow of data traffic in an organized manner. A switch is a very intelligent device. It easily identifies to whom the data should be sent.

Transferring the correct data packets to the appropriate units increases the network bandwidth. Therefore we can say that by using Switch in place of Hubs, there is no unnecessary data load in the network. From this unnecessary data flow, the same amount of information is sent to all the units whether they are needed there or not.

Hubs are used more in small networks, while Switch is used in large networks. These network hubs are devices that follow the OSI model. layer one (physical layer) while switches layer 2(data link layer) operates in the OSI model.

Often a switch and a hub are combined and used according to a switching hub, and this helps to deliver the right data packets to the right place.

What are the uses of Hubs?

These network hubs can be used in place of switches because they are not very expensive. Along with being cheap, they are used in many works only.

  • In some special cases, hubs are used in place of network taps for effective installation of the protocol analyzer.
  • Network hub is very efficient to receive very large traffic load which comes for cluster of computers.
  • These are very easy to use. Whereas if we had to use switch instead of hub then we have to configure the switch settings first.
  • They can be used a To establish the loop, where it is necessary to provide a connection to the end users in a presentation hall.
  • Hubs can be used for network extension because network hubs repeat each and every data packets further to whatever is sent to them.
  • Whereas hubs are used more specifically in small networks.

How to set up a Network Hub in your home?

If you want to set up a network hub in your home, then for this you have to do some important steps. like before you Internet connection must be brought ISP (Internet Service Provider). Once your Internet connection is installed, then you can connect your network hub with the modem and for this you can use a network cable (Cat5 or RJ-45).

After this, if you want, on your computer NIC (Network Interface Card) can also connect with another cable. You can also do this with your other computers and printers that are in your network. Whereas if you have a wireless network, then you can use a wireless hub; Just make sure that your hub has as many wireless ports available as your connection.

What are the Advantages of Hub?

Let us know about the Advantages of Hubs.

  • It can easily be extended over the entire distance of the network.
  • Using them does not affect the performance of the network much.
  • They are very cheap so everyone can use them.
  • Many different media types can be easily connected with them.

What are the Disadvantages of Hub?

Let us know about some disadvantages of Hubs.

  • It does not have many advanced mechanisms such as collision detection and retransmission of packets.
  • They do not operate in Full Duplex Mode.
  • These other network architectures such as token ring And can not connect with ethernet.
  • It cannot be used to filter information ie it passes packets to all connected segments.
  • There is no mechanism to reduce network traffic in this.

What are the applications of Hub?

Networking Hub is a very widely used networking connectivity device. It has many advantages compared to other connectivity devices. Let’s try to know about some applications of Hub:

  • Hubs are used to create small home networks.
  • Hubs are used to monitor networks.
  • These hubs are used for connectivity in many organizations and computer labs.
  • By using it, it makes a device or peripheral available in the entire network.

Why is the hub used?

hub (Hub) is a network device used to connect multiple devices together used Is.

What is meant by gateway?

Gateway A hardware device that connects two networksgate” serves as. This can be a router, firewall, server, or other device that enables traffic to move in and out of the network.

Why is the switch called an intelligent hub?

The switch is called an intelligent hub because it addresses the hardware itself. Let’s prepare the table, they are also different To track the hardware addresses properly, as well as the ports to which each hardware address belongs.
