 What are Networking devices?

As I said in the previous post, what is Computer Network, and what are the types of it? In that post, I also said that in the next coming post I will tell you about Networking.

A lot of people think that both networks and Networking are the same and if you have to give its definition anywhere, then you give the same definition of both, which is totally wrong. Both words are the same but one word is the first form of Verb, the second word is the fourth form of the verb, but do you know why both are different, what is the difference between them. If not, let me tell you. Hello Friends! Welcome once again to the Guptatreepoint blog. So let's see in today's post what is Networking? And few know about Networking devices.

What is Networking?

When two or more computers and a Networking device are connected to each other to share data transmission and resource through any communication channel, that is, it is called Network or Computer Network or Data Network.

Whereas the entire process of linking and connecting two or more computers and Networking devices with each other is called Networking. In other words, the entire process of creating and using any computer network is called Networking. We need Hardware, Software, and Protocol to create a computer network, we can also make computer network wired or wireless.

To share common data and information with any individual or group, we create a network and the process of creating this entire network is called Networking.

Benefits of Computer Network

There is a motive behind creating anything which is seen as a benefit. Computer networking has become a very good way to share information, through which many computers are linked with each other, that is, connect and exchange data among themselves. There are some advantages and disadvantages of making Computer Networking, so let's first know about its advantages.

1. Faster Communication

I told you that Networking is the process of connecting many computers together. Networking is generally designed for communication and data exchange. Through computer networks, we can message anyone in real-time and they can also reply to us by instant messaging. When we did not have Networking, we used to send our message through the post office (post office) which was a very lengthy process, and from that, the message did not arrive at the right time.

But since Networking has come, since then we can send our message to anyone anywhere in the world in seconds. This made our communication much faster. Through this, we can send our message or any type of file.

2. Boost Storage Capacity (Storage capacity will increase)

When you connect computers through the network, you do not need to store the same data in all computers, meaning that you can use the data of the same computer in all connected computers, and in this way the storage capacity of your computer increases. This means that you will save your storage space in which you can store other information.

3. Inexpensive Cost (Cheap Cost)

When you install a networking system, you can use the same resource with all connected computers, this will save your money. For example, if you want to run an institute, you can connect a single CPU (Central Processing Unit) with a lot of desktops, so that you have to spend only one CPU.

4. Easily File sharing

By installing the Networking system, you can use the same file in all connected devices, for this you do not need any separate storage space. For example, if you have connected a lot of desktops to a CPU in your institute, then all those desktop users can easily see the file kept in that CPU, meaning that the file can be easily shared among all. You do not have to copy-paste that file again and again.

5. Resource Sharing

You can use one resource (such as a printer, CPU, and other hardware devices) with many devices through a networking system, through a networking system, you can share a single resource with all devices. For example, if you have gone to any Internet cafe, then you must have seen that the same printer is connected with all the computers that share resources.

6. Easy to use

Due to the networking device, you will not need to install any software repeatedly in all computers nor do you need to make any Changement again and again, so it is very easy to use.

Disadvantages of Computer network - Disadvantages of computer network
When there is the benefit of anything, it is also necessary to lose it, like if you take the exam then it is necessary for some people to fail and some people to pass it, if the system of failure does not exist then all will pass. And it is not possible to know who has good knowledge and who does not have it. Similarly, there are some advantages to a computer network, then it will also have its disadvantages like a coin has two sides. So let's see about its loss.

1. Security Issue
When a lot of people will be added to your network, either one of them will want to harm you or an outsider will want to harm you when people share resources and files between each other, then an illegal person will definitely try to harm them. The security problem is very common with network and this is the disadvantage of computer network.

2. It lacks robustness (it lacks strength)
Whenever the main server will break down, meaning that all the systems connected to it will become useless, that means without the work, then all those systems will not work. If any bridging device (connecting two networks) or the central linking server fails, then all the systems connected to it will fail. To deal with this, the main server powerful system is created so that all these problems can be easily dealt with and it does not fail quickly.

3. It requires an expensive set-up
When you install a computer network, you will incur a higher cost because for networking you will need some network devices (such as Switch, hub, router, etc.) which will increase the cost, meaning that it will cost more. Apart from this, you will need Network Interface Cards (NICs) to do Networking. If you have not already installed Network Interface Cards, then it will also have an impact on cost.

Networking Device (devices used in the network)
Some basic hardware components used in the network:

1. HUB
Hub is also called Network Hub. This is a common networking device used to connect a segment (part) of a LAN. The hub has multiple ports when any packet reaches a port, it copies all the ports so that all the LAN segments connected to that hub can see this packet. Hubs are of two types Active Hub and Passive Hub.

2. Switch
A network switch is a computer networking device that works by connecting devices to a computer network by packet switching, through which data is sent from the source device and then the data is processed and then received near the Destination device. A network switch is also called the Switching hub, Bridging hub, and MAC bridge. Switch image

It filters the data between ports according to MAC address in the packet of information, meaning that it tries to filter the data and find out which port to send this data to. The switch has multiple ports and stores the MAC address (Media Access control address) of all ports in a table so that information can be sent directly to that port according to the MAC address. It does not copy the data near all the ports, so it is called an intelligent device.

3. Router
A Router is a Networking device that works to forward data between computer networks. Generally, Router works to connect different types of networks. The router works like traffic directing, meaning that it works to tell the route. All the data that is sent over the internet is in the form of a packet. When the packet of information is forwarded from one router to another via a network then an internetwork is formed until the data reaches its destination node. Router Image (WIFI

When any packet of information falls in any line of the router, the router first reads the network address of that information to find out about its destination node and then transfer it to the next network to take it to the destination node. Let us do it.

4. Bridge
A bridge is a computer networking device that works to connect the same type of network. This is completely different from the Router because router works to connect two different networks whereas Bridge works to connect the same network. In the OSI Model, bridging is performed in the data link layer.

Bridge example: As you may have seen in your city, bridges are made to connect the same type of road so that both roads are connected to each other. In the same way, a bridge is used to connect the same type of network so that data transmission takes place between the networks.

5. Repeater
It is an electronic device that works by receiving the signal and retransmits it. It is known by its name that it will do the work of repeating, that is, it will do the work of repeating anything. Its function is to increase the signal strength so that transmission can go far.

A repeater is used to increase the transmission power eg if any telephone call is being sent through the telephone line, then some power is lost in deciding the distance too long, which spoils the audio quality and The sound is unable to reach the other end completely, so the repeater is used so that it can again forward that audio signal with high power and the audio signal can reach the other end completely.

6. Interface cards:
Network Interface cards (NICs) are also called the Network Interface Controller (NIC, Network adapter, LAN adapter, and Physical Network interface. It is a computer hardware component used to connect computers to computer networks.

The network interface card is already designed in personal computers and workstations, it has been specially designed for LAN Transmission Technology.

7. Firewalls
A firewall is a network security system used to control and manage incoming and outgoing network traffic. Firewall rejects unsafe network traffic from accessing, that is, stops and allows Safe network traffic to access it. It establishes a barrier between unsafe network traffic and safe network traffic to prevent unauthorized access.

Conclusion and Final Words

Computer networking is a very fast and successful way of transferring data, it has made the work of people very easy, that means we can send information from one place to another in seconds. There are three types of computer networks generally: LAN, MAN, and WAN.
