The network allows PCs to interface and talks to various PCs through any medium. LAN, MAN, and WAN are three important systems designed to work in their distribution area. There are some similarities and similarities between them. In sharp contrast to this is the geological area where they are distributed, for example, the area covered by the LAN is the smallest. The area covered by the metropolitan area network is larger than that of the local area network, while the area covered by the wide-area network is the largest.

There are also different types of computer networks, such as:

  • Container (Personal Area Network)
  • SAN (Storage Area Network)
  • EPN (Enterprise Private Network)
  • VPN (Virtual Private Network)

Neighbor (LAN) –

The LAN or local area network interface arranges gadgets so that PCs and workstations can share information, equipment, and projects. The collection of PCs and gadgets are linked together by a switch or a group of switches and use private collusion characterized by TCP / IP conventions. According to the different PCs arranged by the neighbors, the private location is excellent. Switches are located at the border of the LAN, associating them with the larger WAN.

Since the number of connected PCs is limited, the information transmission speed is very fast. By definition, the association must be fast and usually cheap equipment (such as a center, arrange connectors and Ethernet links). The terrain area of ​​the LAN is small (the size is limited to a few kilometers) and is proprietary. People can use it for business, family, clinic, school, and other places. The local area network has little structure and keeps up. The communication medium for LAN has a twisted pair link and a coaxial link. It covers short intervals, so errors and confusion are limited.

The information rate of early LANs was 4 to 16 Mbps. Today, the speed is usually 100 or 1000 Mbps. The extension delay in the LAN is very short. The smallest LAN may use only two PCs, while the larger LAN may require many PCs. LAN usually depends heavily on the speed and security of wired association, while remote association can also be part of the LAN. The LAN is more adaptable to internal faults, and there is less blocking in the system. For example Extensive research on playing Counter-Strike in a similar room (no internet).

Metropolitan area network (MAN) –

Compared with the wide-area network, the metropolitan area network or metropolitan area network covers a larger area than the local area network, and the local area network covers a smaller area. It interfaces with at least two independent PCs, but they live in the same or different urban communities. It covers a vast land area and may be filled as an ISP (Internet Service Provider). MAN is suitable for customers who need a fast network. The speed of MAN is up to Mbps. Planning and maintaining a metropolitan network is difficult.

Reduce the adaptability of MAN to non-serious failures, in addition, there are more obstacles in the system. It is very expensive and can be imagined to be protected by a separate association. The Metropolitan area network information movement rate and propagation delay are moderate. Gadgets used to transfer information through MAN include modem and cable/cable. The MAN example is part of the telephone organization and can provide a fast DSL line for customers or digital TV in the city.

Wide Area Network (WAN) –

A WAN or wide area network is a PC organization. Although it may be restricted by a certain state or country, it will extend over a huge terrain area. WAN may be an association where the LAN interacts with other LANs through telephone lines and radio waves and may be limited to joint ventures (companies or associations) or open to the general public. Innovation is rapid and usually expensive.

There are two types of WAN: switched WAN and point-to-point WAN. WAN is difficult to plan and keep up with. As the metropolitan area network, the adaptability to non-serious faults of the wide-area network is also small, and there is more congestion in the system. The communication medium used for WAN is PSTN or Satellite Link. Due to a large number of distance transmissions, there is usually more chaos and errors in the WAN.

The information rate of the WAN is delayed by about one-tenth the speed of the LAN because it includes extended intervals and the number of expanded servers and terminals. The speed of WAN is almost from several thousand bits per second (Kbps) to megabits per second (Mbps). Delaying sexual intercourse is perhaps the most serious problem here. Gadgets used to transmit information over the WAN include optical fiber, microwave, and satellite. The case of switching WAN is a non-parallel mobile mode (ATM) system, while point-to-point WAN is a dial-up line that connects a home PC to the Internet.

Conclusion –

There are many advantages of LAN on MAN and WAN. For example, LAN has shocking firm quality, high information transmission rate can be monitored without effort, and also provides edge accessories. Neighbors cannot cover urban areas or towns, so an urban area network is needed, which can bring cities or urban communities together. In addition, for interfacing with a country or a collection of countries, a wide area network is required.

FAQ-

How does a metropolitan area network work?

Metropolitan area network (MAN) is similar to local area network (LAN), but spans the entire city or campus. MAN is formed by connecting multiple LANs. … the metropolitan area network is very efficient and can provide fast communication through high-speed carriers such as fiber optic cables.

What is the Metropolitan Area Network example?

The metropolitan area network is a type of network that serves a large geographic area within a range of 5 to 50 kilometers. … WAN connects LAN and MAns. One example is the Internet.

Who uses a metropolitan area network?

Local area networks are used in office buildings, schools, and rooms, metropolitan area networks are mainly used in cities, and wide area networks are used in states, provinces, or countries. The metropolitan area network usually connects the enterprise to the enterprise and connects the enterprise to the wide-area network.

What is a small metropolitan area network called?

A metropolitan area network (MAN) is a network that interconnects users with computer resources. Computer resources in this geographic area or area are even larger than those covered by a large local area network (LAN), but they are covered by a wide area network (WAN). The area should be small.
