Many hardware components have the role to fulfill Internet or any common computer network system or to work properly. Router, hub, and switch are extremely essential networking devices. They are all used for the same work-but each of them has different and special significance. Now the question is, what are the differences between each other? What are the special importance of them? And in fact, why are they all in their position? Without the ability to imagine networking, it is necessary that we know the details about the divisions. So let’s take a look at friends, they break everything.

  1. Hub

Hub

Many people have used the hub (local area network) to connect computers together. If any information is sent to any port in the hub, information will be sent to all the ports of the port, i.e. it will be attached to all ports. Can not send data from a particular computer to a computer connected to the Hub, the Canena Hub does not have any information about the computer connected to it. If you get information from the port, it will be conveyed to the rest of the ports like the ear.

Hub works like a normal electric multiplug – where multiple plates are transferred from one end to the pipeline and all the ports provide electricity. Multiplication is never understood by any plug-in with a plug-in. Think, five computers are connected to a hub, now if the data is sent from the computer, it will accept the remaining four computers without going to the specified computer.
Hub requirement

Hub is not really necessary for home use-any information you send will be copied on all devices. In addition, using hubs means to maintain safety at sea, it is possible to monitor all traffic from any device associated with it. In addition, hub bandwidth eliminates jam.

But there is no need for that, but it is not so. Let’s say that your office boss needs a copy of the document print but not only on your copy, you should have a copy of the printed copy of every employee in your office and all print copies should be only a printer. In this case, you can easily control the situation using the hub.

There is no security in the hub, but you can use it as a convenience too. You will be able to monitor all the employees in your office and all the traffic on that network. If any of your employees spend more time on Facebook or YouTube than work, the hub can help you catch them.
Second. The switch

The switch

Switches are used to connect multiple computers together or create a local area network. After transferring the data first, it creates a “switch table” – which remembers the MAC address of each device connected to it and remembers what port is connected to which portjoined.

Unlike the hub, the switch can differentiate between each computer, after the first data transfer, it remembers the MAC address of each port, so it is possible to send data from a computer to a particular computer or to a specific port.
Switch requirements

If you use a hub to create a general and private local area network – this is cheaper than a switch. But switching is more secure and efficient, and it reduces much less bandwidth. You can also send data from a computer to a particular computer. After watching the switch, it was seen that “A” computer is connected to port number 1 and “B” is connected to port number 4. In this situation, the switch will send the data from 1 port to port 4 port, avoiding receiving the remaining port data, so it would be possible to save more bandwidth than the hub.

When you go to the market to buy switches, you will usually see two types of switches. One is the managed switch and the second unmanned switch. Just plug in unmanaged switches and start servo. But in managed switches, bandwheel will be given preference for specific ports.

  1. Router

Router

The original work of the router is to send data from one network to another on the network packet. Each data packet has a destination address to access that data. Traveling from one router to another router until the returned data returns to the destination. Data from the Internet comes from your local area network. This means that when you search something in Google, your router sends a search request directly to Google servers. Then the data received from the server will be supplied on some computers in your local area network.

The router automatically generates some local IP addresses and provides each and every disc connected to it. Even if a web request has been sent from the device, your router controls all the processes with very efficiency and every data packet can be delivered to the actual destination.
Router Requirements

Although the original work of the router is done by distributing packets between two different networks, today’s modern router works much more than that.

It has 4-8 switch ports, which are used for local sharing, such as using a printer.
By using the Network Address Transaction (NAT) method in your local area, you provide each of these discs a unique IP.
Using the Dynamic Host Configuration Protocol (DHCP), each partition connects to an IP over the local area network.
There is a wide area network (WAN) port that connects your ISP to your local area network (LAN).
In addition, wireless router helps you connect your devices through WiFi.
