What is a Computer Network? There are so many types.
(What Is Network Meaning, Uses Of Computer Network, Computer Network Notes, Computer Network Means)
In today's post, we will talk about Computer Network. In this, you must read this information for the necessary information related to Computer Network.
Earlier, it was possible to send information from one place to another only through Postman. This trend is still today.
But there is a lot of delay in sending and receiving information from one place to another through all these mediums. Due to which important information could not be reached on time.
But the way the Internet has developed in the world, it has brought a revolution in the field of digitally exchanging any information. Through which we can send information from one place to another within seconds.
In this post related to Computer Network, we will know what is Computer Network? History of computer network, which was the first computer network? Types of computer networks, benefits of computer networks, etc.
Now we will know about it in detail.

What is a Computer Network?
(Computer Network means, Definition Of Network, What Is Networking)
When two or more computers are connected with a wire or through wireless, it is called Computer Network.
The work of any network is to exchange information from one place to another.
Which connect to each other through any communication channel and do the work of communication or resource sharing?
When a device is connected to a network, it is called networking.
Wire Medium is the one that is connected to any of the Twisted Pair Cable, Coaxial Cable, and Fiber Optics Cable.
Wireless Medium is one that is connected through Radio Wave, Bluetooth, Infrared, Satellite, Online Internet.
Computer Network that works with the Combination of Hardware and Software. Which allows communication between computers on the network.
When two devices connect with each other, either one of them is able to share data between the two, then at that time, we can call that device also Networked Device.
This can be Device Computers, Servers, Mobiles, Routers, etc.
History of computer network
(Computer Network History)
Computer networks were introduced in the 1960s to 1970. The name of that network was Arpanet. Which is called Advance Research Project Agency Network.
During the 1960s, Paul Baron and Donald Davis began work on Packet Switching with the aim of sharing information between two computers. And electronic telephone switch was launched in 1965. Which was used to control the computer?
Initially, the purpose of that network was to connect the terminal and remote job entry stations with the mainframe.
Arpanet was quite reliable as it used packet switching technology instead of circuit switching.
Arpanet was also used in the US Department of Defence so that the Guinea threat could be sent. Gradually, after further development, industrialists also started using it.
The result of this is that today it has become the largest network in the world, which we know as the Internet.
What was the first computer network?
(First Computer Network, Networking)
The world's first computer network name was Arpanet.
Arpanet was the first computer network to use packet switching.
The first Arpanet message was sent on 29 Oct 1969.
Type of computer network
(Network type, Types of Networking)
There are many types of computer networks. This includes the type of network according to the design, capacity, working style of each network.
Out of this, separate networks have been made to connect small and big Areas.
There are mainly three types of computer networks. Such as Lan, Man And Wan, but apart from this, there are many computer networks available to know about.
Lan (Local Area Network)
Man (Metropolitan Area Network)
Wan (Wide Area Network)
Wlan (Wireless Local Area Network)
Pan (Personal Area Network)
Han (Home Area Network)
Lan (Local Area Network): - Local Network or Small Area Network of any organization is called Lan Network.
It is a computer network covering local areas such as home, office, or building groups.
You will find this network everywhere such as Office, College, School, Business Organization, Data Storage, Document Printing, this network is used.
To make this, Hub, Switch, Network Adapter, Router, and Ethernet Cable are required.
The smallest lan can be made up of only two computers. In a Lan, we can connect 1000 computers.
Lan can be enabled via Wi-Fi or Ethernet. When you share your Wi-Fi connection with someone else, Lan is also enabled here.
Man (Metropolitan Area Network): - Metropolitan area network is spread over a larger geographical area than LAN.
It is a high-speed network that can carry voice, data, and images at a speed of 200 megabytes per second or more, up to a distance of about 75 km.
It is a network larger than Lan (Lan) and smaller than Wen (Wan). Through this network, one city is connected to another city.
Wan(Wide Area Network): - Wide area network allows long transmission of data, voice, image, and video. A Wan is larger than a Man network.
WAN is used to transfer data across large geographic areas, such as countries, continents, or the entire world.
Wlan (Wireless Local Area Network): - Wireless means without wire i.e. without wire. With which we connect our Networking Device to any Wi-Fi.
It works just like Lan but it does not have only Wire, meaning it works without Wire. It works on the base of Radio Wave.
Pan (Personal Area Network): - It is a computer network that works to connect the workspace of a personal person.
This is a small network that has its limits inside a house.
Han (Home Area Network): - Home Area Network is also a type of private network. With the help of this network, other devices available in a house such as Printers, tablets, Speakers, Laptops, etc. are connected among themselves.
It also has a Home Area Network with Internet Connection or Wi-Fi over Wire. But Wi-Fi technology is better used in this type of network.
Components for Computer Network
Computers, Switch, Router, Hub, Modem, Cables, Repeater, Network Cards, Bridge, etc.
Benefits of computer network
(Advantage of Computer Network in Hindi)
There are many benefits of networking which are given below:
Kosi files are shared by computer networking.
It can share devices like printers, scanners, CD-ROM drives, hard drives, etc.
Applications can also be shared on the network.
In this, the users are used to work like e-mail, video conferencing, etc. within the network.
This leads to maximum work being done at the least expense.
So or was the information about Computer Networking. In which we have tried to describe the complete information of "What is a computer network?"
In this post, we learned what is Computer networks? History of computer network, which was the first computer network? Types of computer networks, benefits of computer networks, etc.
