The difference between WAN and LAN, the difference between WAN and LAN

Difference Between WAN and LAN1. Wide area network: It is a remote network that connects computer communication in different regions of local area network or metropolitan area network.

2. Local area network: It is a regional network formed in a local area, and the distribution area is limited.

1. Wide area network: spanning a large physical range, covering a range from tens of kilometers to thousands of kilometers, it can connect multiple regions, cities and countries, or across several continents and can provide long-distance communication, forming an international long-distance network.

2. LAN: The coverage area of LAN is within a radius of several thousand meters, and it has the characteristics of convenient installation, cost saving, and convenient expansion.

The difference between the two is simple.

Wide area network, large scope, now basically refers to the Internet (Internet) covering the entire country, covering the whole world, in the wide area network users can interconnect and share their information to others.

LAN, small range, usually can refer to the scale of an Internet café, or the scope of a whole building, the use of communication exchange equipment to connect various terminal equipment such as computers and mobile phones together, small scale, small range may be a room is the scope of an Internet café, the equipment in this can communicate with each other, but can not be connected to the outside network (such as the WAN is what we often call the Internet Internet), if you need to connect to the outside WAN also need to pull a fiber optic fiber, from the LAN to the WAN, In this way, the LAN is interconnected with the WAN, and of course, the LAN is also part of the WAN.

Local Area Network

The coverage area of the LAN is generally within a radius of several thousand meters, and it has the characteristics of easy installation, cost saving, and convenient expansion, which makes it widely used in various offices. LAN can realize file management, application software sharing, printer sharing and other functions, in the process of use, by maintaining LAN network security, can effectively protect data security, to ensure that the LAN network can operate normally and stably.

The local area network connects various computers, external devices and databases in a certain area to form a computer communication network, and connects with the local area network or database in other places through special data lines to form a larger range of information processing systems. The LAN connects network servers, network workstations, printers and other network interconnection devices through network transmission media to realize system management files, share application software, office equipment, send work schedules and other communication services.

Wide Area Network

WAN is also known as WAN, extranet, and public network. It is a remote network that connects computer communication in different regions, either a local area network or a metropolitan area network. It is usually spanning a large physical range, covering a range of tens to thousands of kilometers, and it can connect multiple regions, cities and countries, or across several continents and provide long-distance communication to form an international long-range network.

A WAN is not the same as the Internet.

A local area network is a computer network that connects computers in a limited area, such as a home, school, laboratory, university campus, or office building. In contrast, WANs not only cover large geographical distances, but also often involve fixed leased lines and connections to the Internet. In contrast, the Internet is much broader and is a system that connects businesses and personal computers around the world.

Difference Between LAN and WAN

LAN and WAN ranges are different. LAN is a closed computer group built by more than 2 computers with network cables and other network equipment in a fixed geographical area, with a range of several kilometers; A WAN is a collection of networks with a very large geographical span, ranging from tens of kilometers to thousands of kilometers.

The IP address settings are different. The LAN must have a unique IP address on the network, which is unique, and the IP address can still be used in another LAN. Each dedicated computer or other network device on a WAN has one or more WAN IP addresses and cannot be duplicated.

The way it is connected is different. LAN is connected by switches, while WAN is connected by routers.

Wide Area Network

A wide area network (WAN) is a collection of computer networks that span large and geographically specific areas. Often across provinces, cities, or even a country. A WAN consists of subnets of different sizes, which can be either LAN or small WAN.

Difference Between LAN and WAN

The LAN is in a certain area, and the WAN spans a large area, so how to define this area? For example, the head office of a large company is located in Beijing, and the branches are located all over the country.

If the company connects all its branches together through the network, then one branch office is a local area network, and the entire head office network is a wide area network.

The scope of these two concepts is not the same.

LAN is in a fixed range, there are two computers connected with network cables and other network facilities together to build an independent computer system, the scope of the LAN is limited, about a few kilometers or so.

The IP address is not the same.

To surf the Internet in a local area network you must have your own IP address, which is still useful in other local area networks. Every computer on a WAN has one or more WAN IP addresses.

1. The scope of the two is not the same. LAN is a closed computer group built by more than 2 computers with network cables and other network equipment in a fixed geographical area, with a range of several kilometers; A WAN is a collection of networks with a very large geographical span, ranging from tens of kilometers to thousands of kilometers.

2. The IP address settings of the two are different. In a LAN, there must be a unique IP address on the network, which is unique, and in another LAN, this IP address can still be used. Each computer (or other network device) on a WAN has one or more WAN IP addresses and cannot be duplicated.

3. The way the two are connected is different. LAN is connected by switches, while WAN relies on routers to connect multiple LANs into a noisy row.

Difference Between LAN and WANFirst, the scope is different.

1. The scope of the LAN is relatively small, generally about a few kilometers.

2. The coverage area of the WAN is relatively large, ranging from tens of kilometers to thousands of kilometers.

Second, the role is different.

1. The LAN can realize the functions of file management, application of soft and hidden parts sharing, printer sharing and so on.

2. The WAN can connect multiple regions, cities and countries, or across several continents and provide long-distance communication, forming an international long-range network with friends.

Third, the connection method is different.

1. The LAN is connected by a switch.

2. The WAN relies on routers to connect multiple LANs.

Fourth, the interface type is different.

1. The interface types of LAN are AUI, BNC and RJ-45 interfaces, as well as FDDI, ATM, optical fiber interfaces, etc. Acacia.

2. The interface types of WAN are E1, POS, ATM, etc.
