What is network and how many types?

Do you know what the network is and the type of networking. And what is the history of the network. Kiana is well aware of this. Many years ago, when people used to talk to each other and send messages, people still had the same objective. Information sharing means sending something from one place to another. But this work was not so easy in that thread.

People used to take many days to send one information to another place. In this, people would have a lot of problems like taking too much time, tiredness to go far, sometimes they could not get information. A question will come in your mind, what does this information mean? It can be anything like a message, text. photo, document, songs and video.

Networking is from ABACUS itself. Then used to send answers from ABACUS. Now the same has happened in ABACUS Computer. Now the same is being used. So now we will give you complete information about what is the Networking. Let's start.

Two or more computers joining together is called a network. You can add them to Wire or Wireless to share data. Talking about Wire Medium, it can be any of twisted pair cable, coaxial cable and fiber optics cable. Talking about Wireless Medium, it will be one of Radio Wave, Bluetooth, Infrared, Satellite.

What is Internet and who owns it
What is URL and how does it work
A network is a collection of all computers, servers, mainframe, network devices. In which data sharing is common. Internet is the most excellent example of a network. Where millions of people stay connected and share data. Networking devices like Router, Hub, Switch, Modem are all used in a network. Whatever I have explained above is called network.

Node is spoken to every computer connected in the network. We can share resource sharing such as Internet, Printer, File Servers along with common data sharing. Resource sharing means, when you go to Net cafe and Cyber ​​cafe, then you must have seen that there are many computers connected to each other. We can also speak Network. But one or two printers live in that cafe. Whenever you print from any computer, then print comes out from the same printer. So here with the help of Pay Network, we are sharing one resource means one printer. This is called Resource Sharing.

The world's largest network is the Internet, in which we keep sharing something everyday. Like whats app, image, video, contact, song all this is made possible with the help of a network. By the way, when we use our phone, everyone speaks, the network is not eligible. This means we are not connected with other mobiles and with Tower. This was some information What is Network in Hindi. Now we will tell you about the criteria of network.

Network definition
With these few criteria, we can tell whether the network of the network is excellent or not. That is Performance, Reliability, Security. Everyone knows about it in detail.

1. Performance
We can measure performance in a very good way. Among them are Transmit Time and another Response Time. At the same time, a message from one device to another device is used by Pohancha to call it Transmit Time. The time it takes to respond to a request is spoken by Response Time. Just like you did some search in Google and the time it takes to get the result is Response Time.

Performance also depends on some other factor. What is the user, which is the Transmission Medium, which is the hardware and software. By the way, two Networking Metrics are used to find the performance Throughput and Delay. We want more throughput and less Delay on demand. The same holds both limits.

2. Reliability
It means being brave. Unless a network is reliable, it can never be a good network. Reliability means Accuracy of Delivery. As long as the data is sent to the device on which it is sending, without link failure, it is reliable. After the link failure, the time it takes to recover from the back is reliability.

3. Security
We can protect the data from Unauthorized Access only by having security. Avoiding damage to data. Implementing policies to protect against DATA lost is the job of SECURITY. If it is stolen from the DATA network, then it will not say our data is Secure. It is very important to have network security.

History of Network
Now the network we are talking about, it was started many years ago in 1960 to 1970. The name of the network is ARPANET to which we call Advance Research Project Agency Network. The network's objective in Suruwat was to connect terminals and remote job entry stations with the mainframe. But at the time ARPANET had a fundamental concept of putting resource sharing concept at that time.

The ARPANET was quite reliable in that door as it used PACKET switching technology instead of Circuit Switching. The ARPANET was also used in the US Department of Defense to be sent to the Guinea threat. In connecting it to different universities of US. Industrialists also started using it. Gradually, he continued to do more development. Today it has become the largest network in the world, on which we speak Internet.

Network Devices
If there is a network, then all the devices in it remain connected, DATA has to be connected, DATA passes through different computers. Two networks to connect and computers to LAN. For all this we need some network devices like HUB, Repeater, Switch, Router, Modem, Bridge. Know about them from bed.

What is SAR Value and how to check?

Do you know what is SAR Value? Do you use mobile phones a lot? If the answer to this question is yes then you must know about SAR Value. Because like a phone bell, it is a danger bell for us. And some wise man said that it is good for us to be alert to danger. As we all know that nowadays mobile phone has become a part of our life. It is time for us to get acquainted with the danger from it. Mobile communication requires various electromagnetic waves. To send and receive such signals, an antenna is required, with the help of which transmission of these waves (or signals) takes place. Whenever there is a transmission, some percentage of the signals radiate to about 10-20% of the atmosphere. This is because there is some power in these signals which dissipate in coming to know, which is also called mobile radiation. This radiation level depends only on the usage of mobile. SAR (Specific Absorption Rate) Value is used to control this Radiation Level. So today we will know what is this SAR...

What is Metro Train and how does it run?

Everyone knows what is this Metro Train or what is Metro Rail, but do you know how this shape works? If not, then you must read this article. As we know our country is moving forward on the path of progress, its population is increasing more. Because of being a developing nation, there are many difficulties in its progress, in such a situation, problems of transportation or transportation are also emerging. Our scientists are working day and night to solve all these problems. Metro Rail has been a major contributor to providing traffic to the growing population, with the help of this many people are able to go from one place to another very easily. Since it carries traffic in underground tunnels in most places, it also has little problem of traffic. If seen, the metro rail in our country has been around for 25 years, but its increasing need has made it a very useful medium for traffic. So today we will know what is this Metro Train or what is Metro Rail and how does it work. Then what ...

Image What is stabilization and how does it work?

Do you know what this image stabilization is (what is image stabilization in camera) and how it works, if yes then it is a good thing and if not then this article is for you. Like we know that sometimes when we are clicking a photo, sometimes the picture becomes a bit blur or blurry because it is because our hand may be slightly shaken while the photo is being pulled, due to which the picture is complete Clear is not drawn. It hurts our heart a lot. But what should we do, we are an honest person, and humans make mistakes. Have you ever thought that despite something like this happening in mobile, Picture comes clear. How does the technology behind it work? If you want to get complete information about all this, then this article is Image Stabilization and how it works. Because today I am going to tell you about this topic. Then what is the delay? Let's start. Image Stabilization (IS) This is a method with which we can correct the habit of taking blurry pictures to a great extent. I...
