Computer network:
The composition that connects two or more computers into one another is called a computer network. The information can be transmitted to the network. Depending on the needs of computers in the network, it is easy to use different programs or hardware accumulation. 1 server is created in the network. They are added to the rest of the PC. In essence, it is important to share services and information from hardware parts.
Computer networks have the potential to benefit themselves.
1) Sherring of data: - Information about more than one computer can be shared, so it can be possible to view or view information in a departmental office on a computer at the same time, thus saving time and effort.
2) Sherring of Divis: - A computer can be shared with more than one computer. Eg printer, scanner
3) Communication: - It is possible to engage in messaging with many computers at one time.
There is 1 server in every office. This is a proxy server for accessing the Internet which is given an IP Address. The IP address that is inserted into the IP address is inserted into the computer. This can be given the URL that you have access to the Internet. Even though the network is easy to access data, there are many such problems. One is the Virus Problem. Virus means that if the file exceeds the file due to the exe file, the virus removes the system's PC file due to which the PC becomes a problem.
The network can not see data as it is due to the network and no one can see this data. No one can access data if sharing is removed. The network needs a very specific code or password. If the network remains open, then anyone can access it, it can be used remotely. Or network may be hacked. Now the Internet uses hackers to send email to hack another's network. Cable is not required in the place where the wireless network is located. It can be connected via a wireless network setting in a PC network. The most beneficial part of the network is that network printer is printed in the same printer in the network by adding it to the network connected to the network so that it reads the cost of the printer and reads the space. Networking is networked by adding router, hub, switch, satellite or modem. CAT 5 cable is networked by optic fiber cable.
The network's classification is based on the size and structure of the network so that there are 3 types of networks.
1) Local Area Network (LAN): -
Computers in the same building or section are connected to each other, called local area networks. In this network, the computers are connected to one another by cable. There is less computer connectivity in the network. This network is cheaper than the rest of the network, LAN card and cable is required in LAN. LAN is used for a short distance of 10 kg meters.
2) Metropolitan Area Network (MAN): -
This network is bigger than LAN. Metropolitan area network is connected to the full city. Different cables are used in this network. A mobile company is possible in different parts of a city. A network of telephones or radios is the network of man.
3) Wide Area Network (WAN): - When a network of two cities is connected to another, the network is called Wide Area Network. These networks are connected via a telephone line or via satellite in the satellite.
