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 the information. A question will come in your mind, what is the meaning of this information? 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.


(What is Network)

What is network and how many types?


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.

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 a lot of computers connected between them. 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 every day. 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 that 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 the 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. Know about each one in detail.

1. Performance
We can measure performance in a very good way. Notable among them are Transmit Time and the other is Response Time. At the same time, a message from one device to another device is used by Pohanch, which is called 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. How much is the user, which is the Transmission Medium, which is the hardware and software. By the way, two Networking Metrics are used to find out 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, then it is reliable. After Link Failure, the time it takes to recover from back again is the same reliability.

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

History of Network
Now the network we are talking about, it was started many years ago from 1960 to 1970. The name of the network is ARPANET to which we call Advance Research Project Agency Network. In Suruwat, the purpose of the network 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 the PACKET switching technique rather than 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 call Internet.

Network Devices
If there is a network, then all the devices in it remain connected, DATA has to be known, 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.

HUB
What is a hub? This is a Basic Networking Devices. This device works in the physical layer. For this reason, it physically connects networking devices among themselves. On the network in which the twisted pair cable is used, this device is used. Without any change, it works to forward a packet to other devices. Whether or not the "data packet" is for the device, it transmits all these devices without doing it. There are two types of hub: Active HUB and Passive HUB.

Switch
What is the switch? This device also works on a physical layer like HUB. This DEVICE is more intelligent than HUB. HUB simply forwards the Data Packet but also filters along with Switch Forwarding. Therefore, it is called intelligent.

When Switch Receives DATA Packet. Then he finds the address of the address by filtering it. And packe that device

Types Of Network 

By the way, there are many types of Computer Network. They have been divided according to their size, geographic area and how many computers can live in a network. Starting from a network of small rooms, it can connect computers from all over the world. So let's know the types of network.

There are 3 types of network on AMATOR LAN, MAN and WAN. After leaving them, there are other things too, such as PAN, HAN.

1. Personal Area Network (What is PAN)
This network is also called PAN. This is a small network that has its limits inside a house. For example, in a Building, the PAN contains one or more computers. Along with this, telephone, video game and some other devices are connected.

2. Home Area Network (What is HAN)
If some people in the same residence are using the same network, then we can call it Home Area Network. It is also called HAN. It has internet connection with WIRE on demand. Which is associated with a modem. This modem provides both connection means wire and wireless. You can do all this work in this network. WIFI is also the Home Area Network.

You can also print out the document by sitting in any corner of the house.
You can also upload and download photos
Along with online video sharing, you can also do video streaming.
There is no significant difference between PAN and HAN.
3. Local Area Network (What is LAN)
Local Area Network means LAN. You will find this network everywhere like office, college, school, business organization. This network is used for resource sharing, data storage, document printing. Some hardware is not required to make it, just hub, switch, network adapter, router and Ethernet cable are required.

The smallest LAN can be made up of only two computers. We can connect 1000 computers in one LAN. Most LANs are used in wire connections. But nowadays it is also being used in wireless. The specialty of this network is its speed, low expenses and security. Ethernet cable is used in this.
This network is special for document sharing and printing in an office. What happens in document sharing? A central server resides where all the files are kept. Whichever employee can access the file without going there. If someone has to print also, he can print using the central printer. This is the advantage of LAN. It is called resource sharing.
If a Local Area network is wireless, it is called a wireless LAN.

USP

It is limited in the small geographical area.
A home is used in Office and college.
It has its ownwrship private
This network can be easily created
The data transmission speed of this network is high
4. What is Metropolitan Area Network (MAN)
You can also speak Metropolitan Area Network or MAN. This is a network connecting all the cities. This network connects all the big colleges, schools, government office networks in one city. MAN is a larger network than LAN. MAN covers from 10KM to 100KM. It is used to create a large network by connecting all the LANs interchangeably.

If such networks start being used in a college campus, then they call it campus area network. Its best example is cable TV Network. MAN is used to connect LAN to LAN. A big business organization becomes its own MAN. Through which he can connect his different branch.

USP

It is confined in large geographical areas such as town, city.
Its ownership is public and private.
It costs more to install this network than a LAN.
The data transmission speed is moderate.
5. Wide Area Network (What is WAN)
The network that comes after LAN and MAN is Wide Area Network. By the way, this is the largest network that connects computers across the globe. It is also called WAN. Wide area network is called LAN of LANS. The specialty of this network is that the DATA rate is low, but covers more distance. Internet is the best example of Wide Area Network.

WANs are of two types 1. Enterprise WAN and 2. Global WAN. Computers connected with wide area network mostly use public networks such as Telephone line, Leased line and satellites. The largest WAN is the Internet.

By the way, there are a lot of Wide Area Network. Such as public packet network, large corporate network, military networks, banking networks, railway reservation network and finally Airline Reservation network.

Network Service Provider is spoken to the company providing network through WAN. They are called the core of the Internet. The most expensive network is called the WAN. Because some such type of technology is used in it. Such as SONET, Framerelay and ATM.

USP
Large geographical areas such as two countries in Upsa can connect to this network
It is owned by public and private
Installing and maintaining this network is difficult.
data transmission speed is slow
Network 
So friends, today's information is very important. Which has a lot of good information about the network. Like what is network? It is very important for everyone to have knowledge of Networking. Everywhere we are surrounded by network. By the way, it will be easy for students to understand this Networking. Right now you are connected to a network yourself, so you are able to read my article.
