This article uses easy-to-understand examples to introduce what is the difference among local area network, wide area network and metropolitan area network. The code is very detailed. Interested friends can use it for reference. I hope it will be helpful to you.

The differences of local area network and metropolitan area network are: 1, different coverage; 2, different interface types; 3, different transmission rates; 4, different protocols.

The differences between the local area network and the metropolitan area network are:

1. Different coverage

Local area network is smaller than metropolitan area network and wide area network. The transmission distance of the wide area network is generally more than 100 kilometers.

2. Different interface types

Local area network: Ethernet RJ-45 electrical interface, LC/SC/ST multimode fiber.

Metropolitan area network: IP-VPN, Wireless LAN.

Wan: serial port, T1, POS, ATM,E1.

3. Different transmission rates

Wide area Network (10/100/1000/10000/10G/40G/100G).

Man (basic service of 4 kb/s to leased line service of 2.5 Gb/s/10 Gb/s).

Local area network (ISDN/PSTN/T1/E1/T3/E3/OC-3/OC-12/OC-48/OC-192).

4. Different protocols are used

Wide area Network (Ethernet)

Metropolitan area Network (TCP/IP protocol)

Local area network (PPP,HDLC)

Extended data:

Actual use of three types of networks:

1. Local area network (Loxal Area Network,L A N) refers to the computer network formed by the interconnection of computers in office buildings or campus within a few hundred meters to more than ten kilometers. Computer local area network is widely used to connect personal computers or workstations of campuses, factories and institutions to facilitate the sharing of resources (such as printers) and data communication between personal computers or workstations.

2. The technology used in metropolitan area network (Metropolitan Area Network,M A N) is basically similar to that of local area network, but on a larger scale. The metropolitan area network can cover not only several office buildings not far away, but also a city; it can be either a private network or a public network.

3. Wide area network (Wido Area Network,WA N) usually spans a large physical range, such as a country.

On the local area network, wide area network, metropolitan area network what is the difference between what is shared here, I hope that the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
