There are different types of computer networks used for devices like computer, phone, tablet, … This article will help you distinguish between LAN WAN and MAN the three most popular networks today!
1. LAN (Internal network)
– What is a LAN?
LAN stands for (Local Area Network), also known as the local area network, is used in certain confined areas with high transmission speeds.

LAN devices can share resources with each other, typically file sharing, printers, … and some other devices.
– Advantages of LAN
High transmission speed, support to connect many devices quickly. Although limited in scope of connection, but the cost, using less wire, easy to manage.
2. MAN Network (Urban Network)
– What is MAN Network?
MAN Network (Metropolitan Area Network), also known as the urban network, is connected from many LANs through cables, other means of communication, … , the provincial.
The MAN network model is often used mainly for organizations, businesses with many branches, many parts connected together.

Man network is often used for businesses because this model provides many types of services such as connecting voice over (voice), data (data), video (image), deploying applications easily. .
– Advantages of the MAN network
The large range of connectivity makes it easy, efficient, low-cost for interactions between business divisions, stable transfer speeds, information security, and simple management.
3. WAN (Wide area network)
– What is WAN?
WAN (Wide Area Network), also known as wide area network, is a combination of urban networks including MAN and LAN networks through satellite equipment, optical cables, and power cables.

Wide area network was created to connect on a large scale on a national scale. The protocol used in the WAN is TCP / IP, the bandwidth varies depending on the installation location.
– Advantages of the WAN
Extensive connectivity, no signal restrictions, easy information sharing, data storage. The transmission speed is relatively different depending on the area or transmission equipment.
4. Compare LAN WAN and MAN
You can easily distinguish the 3 types of LAN WAN and MAN through the comparison table below:

5. Some other types of networks
– PAN Network (Personal Network)
PAN networks, or small-scale personal area networks, are often used via routers. This routing helps to transmit data on the device to the destination.

– SAN network (Storage network)
SAN networks are often used to connect resources and data between devices on the same network, the transmission speed is very high faster than normal LAN.

– EPN network (Enterprise private network)
This network model is based on 802.3 Ethernet standard, can support 1.23Gbit / s speed in both downstream and vice versa. Especially when this model was born, this is the solution for optical access network not only in Vietnam but also globally.

– VPN network (Virtual private network)
A VPN (Virtual Private Network), or virtual private network, helps users connect to a secure network when participating in community networks. This network model allows users to connect to many different sites similar to the WAN model.
