Divide the network into wide area network, metropolitan area network and local area network based on geographical scope. Among them, a local area network is a network composed of multiple computers used in a small area. The coverage is usually limited to 10 kilometers and belongs to a small-scale network of components of a unit or department.
# Divide the network geographically into wide area networks (WAN), metropolitan area networks (MAN), and local area networks (LAN).
Classified according to the geographical scope of coverage, computer networks can be divided into three categories: local area network, metropolitan area network and wide area network.
Local Area Network (LAN). A local area network is a network composed of multiple computers used in a small area. The coverage is usually limited to 10 kilometers, and it is a small-scale network established by a unit or department.
Metropolitan Area Network (MAN). A metropolitan area network is a network that functions between a wide area network and a local area network. Its network coverage can usually extend to the entire city. With the help of communication optical fibers, multiple local area networks are connected to the public city network to form a large network, so that not only the resources within the local area network can be shared, Resources between LANs can also be shared.
Wide Area Network (WAN) Guangcheng Network is a long-distance network that involves long-distance communications. The coverage can be a country or multiple countries, or even the entire world. Since the geographical distance of wide area networks can exceed thousands of kilometers, information attenuation is very serious. This type of network generally requires leased dedicated lines and is connected through interface information processing protocols and lines to form a mesh structure to solve the routing problem.
