Network is the set of interconnected devices. Thus, we can easily share information like text, video, audio with each other.
Some device such as printers is interconnected through a communication link such as a cable. These devices communicated through a network system. That consisted of Hardware and Software.
That’s why our device of mobile and computer requires a computer network for accessing to others.
The Net is important in our daily life usually like Business, Entertainment, Industry, Banking Sector, etc.
So, we can easily maintain each thing and also saved time. So, It’s much helpful to us.
Advantage Of Network
- Important for file sharing and resource sharing.
- Enhanced connectivity and communication.
- Useful to improve price and performance ratio.
- It has very fast internet access.
- It provides data security and management as well.
Disadvantages Of Network
- Lack of data security and privacy.
- Vulnerability to computer viruses.
- Net failure.
- Administration issues.
Types Of Computer Network
LAN (Local Area Network)
The IEEE 802 LAN is popularly used to shared medium peer to peer communication and broadcasting to the station to station.
LAN is a group of communication devices on the internet. It interconnected within an Office, Building, Computer Lab or Campus.
That enables the station to the communication without any intermedia switching node.
Its own private net. which is arranged in a single building or a campus to cover a few kilometers range. (maximum 3 to 5)
The LAN transmission capacity is more than 1 Mbps.
Characteristics of LAN
- It allows users to share storage devices to the printer, application data, and another resource.
- Transfers data at high speed. (more than 1 Mbps)
- Exists in limited geographical areas. (within few kilometers)
- Multiple accesses. (many can use it at the same time)
- It has a lower error rate.
Advantages of LAN
- Provide a cost-effective multi-user computer environment.
- Fitted in any site requirement.
- Any number of users can be accommodated.
- It allows the sharing of mass central storage and printers.
- Flexible and growth-oriented.
MAN (Metropolitan Area Net)
It may be a single network such as cable television. This connected with the number of LAN’s together as a large. So, the resources of it shared by LAN-to-LAN or device-to-device.
For example, one company can use a MAN to connect the internet for offices purpose. MAN can have covered the whole city.
MAN standard has sponsored by IEEE, ANSI (American National Standard Of Institute). It connected with DEU operating.
It provides a transfer rate from 34 to 150 Mbps.
MAN designed with two and national buses. That’s independent with another bus in the transfer of Traffic.
WAN (Wide Area Net)
WAN provides long-distance transmission of data and voice. That covers a larger area like City, State, Nation, and World.
All the hosts are connected by each other to the communicated subnet which carries messages from Host to Host.
In WAN when a packet sent from one router to another via one or more intermediate routers. That packet received at Each Intermediate Router.
Each subnet connected to the router for point to point stored and forward it by switch subnet. So the packet stored in router until the required output line is free.
Characteristics of WAN
- Exist in the unlimited geographical area.
- More susceptible to errors due to the distance the data can travel.
- Interconnect multiple LAN.
- More sophisticated and complex than LAN.
Types of WAN
Public Net: This connected with many users. So that has less secured. Because all users connected by one IP address.
That may have crashed. Because The System lacks down by the large traffic. So It not suitable for a Business Owner.
Private Net: The Many Users used the private WAN for security. It’s much secured. Because of only One User may have connected.
The Internet has interconnected to WAN. It globally connected to millions of users. More than 100 countries people are exchanging the data, news, and opinions on the Internet.
Network is connected globally. Therefore, we can shared our information with each other. That’s making easier human life evryday.
Today, Network is connected worldwide and also increase up to the new user. That helpful to us to get more news of worldwide. The people are getting more known from the internet.
The net is good. But also, that’s some to change in some categories such as data privacy, data theft protection, etc. Because the hacker is a major issued on the internet.
We require strong protection against the hacker. So, we can safely access the net connection the whole day.
Definitely, the Net is changing the world. Because many of the things that’s going possible by net connection. many businesses going through online. Today, The news report of the United States people’s investing millions of dollars on the internet. It is a big achievement of the internet.
The Internet has to have more popular by learning about Machine learning, Artificial intelligence, and various technology.
