What is Hub? What is Network Switch? What is Router?

What is Hub?

Many people have used the hub (local area network) to connect the computers together. If any information is sent to any port of the Hub, then the information will be sent to the computer on all the ports ie connecting it to every computer connected to it. Can not send data from a particular computer to a computer connected to the Hub, the Kennan Hub does not have any knowledge about computers connected to it. If you get the information from a port, it will be conveyed to the rest of the ports like the ear.

The hub works like a normal electric multi-plug – where multiple plates are transmitted from one end to the plumbing and all the ports provide electricity. Multi-plugin is never understood by any plug-in with any plug-in. Think, five computers are connected to a hub, now if the data is sent from a computer, it will not be able to access the remaining four computers at the same computer.


Advantage of Hub:

Hub is not really necessary for the home use-any information you send will be copied to all devices. Besides, using the hub means leaving the security behind the sea, it is possible to keep an eye on all traffic from any device connected to it. Besides, the hub bandwidth will end up being jam.

But there is no need for it, but not so. Suppose, your office boss requires a copy of a document print, but not only on your copy, you need a print copy made by every employee in your office and there is only one printer for printing all the copies. In this case, you can easily control the hub using the hub.

There is no security in the hub, but you can also use it as a feature. You can keep an eye on all the employees in your office and all the traffic on that network. The hub can help you to catch any employee if you spend more time on Facebook or YouTube than work


What is Network Switch?

Switches are used to combine many computers together or to create local area networks. After first transferring data, it creates a “switch table” – which remembers the Mac address of each device connected to it and remembers exactly which partition is connected to a port.

Unlike the hub, the switch can make a difference between each computer, after the first data transmission, it remembers the port of each port, so it is possible to send data from a computer to a specific computer or to a specific port.


Advantage of Networking Switch:

Using a hub to create a common and private local area network – it’s far cheaper than a switch. But switching is much safer and efficient, and it reduces much less bandwidth. You can also send data from a computer to a specific computer.

Think you want to send a data from “A” to “B” computer. After watching the switch, it was noticed that “A” computer is connected to port No. 1 and “B” is connected to port number 4. In this situation, the switch will send data from Port No. 1 to 4 port directly, while the rest of the ports will refrain from receiving the data, so it will be possible to save more bandwidth than the hub.

When you go to the market to buy a switch, you will usually see two types of switch. One is Managed Switch and another Unmanned Switch. Just plug in the unmanaged switches and start the co-operation. But in the Managed Switches, bandwidth will be given priority for specific ports. For example, you can use more bandwidth ports to make Skype calls.


What is Router?

The router’s real work is to send data from one network to another on a network packet. Each data packet contains the destination address to reach that data. Traveling from one router to another router travels to the delivered data destination. That’s how data from the internet comes to your local area network. That means when you search something in Google, your router sends the search request directly to the Google server. Then the data received from the server will be supplied on a specific computer in your local area network.

The router automatically generates some local IP addresses and provides each partition connected to it. Regardless of whether the web request is sent from the partition, your router controls all the processes with much efficiency and every data packet can be delivered to the real destination.


Advantage of  Router:

Today, the modern router does more than making the router’s main work, because of the exchange of packets between two different networks.

It has 4-8 switch ports, which is used for local sharing, such as using a printer.
Using a Network Address Translation (NAT) method in your local area, each device provides a unique IP. These IPs are outside the Internet or your ISP.
Using the Dynamic Host Configuration Protocol (DHCP) connects each partition in the local area network to an IP.
The router has a dedicated firewall to protect your local area network.
It has a wide area network (WAN) port that connects your ISP to your local area network (LAN).
The wireless router also helps you connect your devices to WiFi.
