What is a computer network?
When two or more computers are added together it is called a computer network. The medium of connecting the computer was used to be the first cable now the wireless network has also been used. We will discuss the types of cables in our next upcoming post. Network term means net in which all the computers are connected in the same way as a network. Through computer network, we can send and receive text, photos, videos, documents, etc. through the message.
Why a computer network was needed
In today's time, data and information are becoming our capital. The more exact and accurate information or information, the more valuable it is. But the information is valuable only when it is found on time otherwise it has no significance. Using computer network, we can easily and quickly exchange information. Sharing of information or information can save time, money etc.
Computer network history
The computer network started in 1969, first of all ARPANET started using it for the first time in the defense field, then gradually the universities were added and gradually increasing the computer network increasing as the Internet. Today every human has reached. Internet term has already been reached from computer network. Whatever we are doing through a computer network, we know this as the Internet.
How many types of computer networks are there.
The computer network is divided into three categories based on its size.
local area network
Metropolitan area Network
Wide area network
local area network :
Local area network is a high-speed network and it is a very small network, it is used to connect the computers in a building or campus.
Features
* The local area network speed is much higher than the rest of the network.
* There is no fear of hacking or theft from the external network.
* The activity on the computer can be easily controlled.
Metropolitan area Network :
The Metropolitan Area Network is larger than the local area network, so its use is used in connecting the computers engaged in many buildings in a metro or city. This network is a smaller area than the local area and the wide area network. In this we can add two or more local area networks together. This 75km Can work till
Wide Area Network:
Wide Area Network is a very large network with the help of which we can connect one country to another country and then using the same network we can divide into smaller networks. The whole world is running on this network. This is the largest network. Different types of techniques are used to connect the wide area network. To create this network, fiber cable, satellite and towers, etc. are added and interconnected. Through this network we can send and receive data anywhere in the world
