What are the classifications of computer networks? What are the characteristics of each of them?

There are a lot of them. Most of the features are resource sharing.

Computer network refers to a computer system that connects multiple computers and their peripheral devices with independent functions in different geographical locations through communication lines to realize resource sharing and information transmission under the management and coordination of network operating systems, network management software and network communication protocols.

1。Local Area Network (local

Usually our common "LAN" refers to the local area network, which is our most common and widely used network. At present, with the development and improvement of the entire computer network technology, the local area network has been fully applied and popularized, and almost every unit has its own local area network, and some even have their own small local area network in the family. The IEEE's 802 Standards Committee defines a variety of major LAN networks:

Ethernet, Token

RING), Fiber Distributed Interface Network (FDDI), Asynchronous Transfer Mode Network (ATM) and, most recently, Wireless Local Area Network (WLAN). These will be described in more detail later.

2。Metro (Metropolitan

This kind of network is generally the interconnection of computers in a city, but not within the same geographical area. The connection distance of this network can be 10 to 100 km, and it is standard. Compared with LAN, MAN extends a longer distance and has a larger number of connected computers, which can be said to be an extension of the LAN network in terms of geographical range.

In a large city or metropolitan area, a MAN network is usually connected to multiple LAN networks. Such as the LAN of the connecting ** institution, the LAN of the hospital, the LAN of telecommunications, the LAN of the company and so on.

3。Wide Area Network (WIDE

This type of network, also known as a long-range network, covers a wider range than a metropolitan area network (MAN), and it is generally interconnected between LAN or MAN networks between different cities, and the geographical range can range from hundreds of kilometers to thousands of kilometers.

4.Internet

The Internet is also known as the "Internet" because of the homonym of the English word "Internet". In today's development of Internet applications, it is a kind of network that we have to deal with every day, both in terms of geographical scope and network scale, it is the largest network, which is what we often call "web", "www" and "world wide web".

1 Divided by the scope of the network.

1) Local area network.

2) Metropolitan area network.

3) Wide Area Network.

2 By transmission technology of the network.

1) Broadcast networking.

2) Point-to-point networking.

3 Divided by the scope of use of the network.

1) Public network.

2) Private network.

Local Area Network (LAN) LAN) metropolitan area network (LAN) MAN), wide area network (WAN; WAN) Internet (Internet) This is so easy...Hehe.

There are 10 types of classification.
