What's The Difference Between A Local Area Network (LAN), Metropolitan Area Network (MAN), & Wide Area Network (WAN)?

Which of the following network is used to connect cities states or countries?

A Local Area Network (LAN) provides a quick, short link between network devices. Most homes and offices have a LAN which allows personal computers and workstations to easily share data between one another at a high rate of transfer. A LAN also enables users to access other devices, such as printers, modems, or local servers. They are privately owned and managed and provide service to relatively small geographical areas. A LAN can serve as few as one user or as many as thousands. Since a LAN covers a small area, noise and error are minimized.
Both a Metropolitan Area Network (MAN) and Wide Area Network (WAN) provide network communications over larger geographical regions. The primary difference between the two lies within the size of the regions being served.
A Metropolitan Area Network is a class of network which serves a large geographical area between 5 to 50 kilometers in range. This geographical area can include several buildings, such as a college campus, sometimes referred to as a campus network, or an area as large as a city (metropolitan area).

These networks are larger than a LAN, but smaller than a WAN, generally providing communications via fiber optic cable, and mostly works within Layer 2, or the data link layer, of the OSI model. Usually, a MAN does not belong to any particular organization, but rather a consortium of users or a single network provider which takes charge of the service, owns its hardware and other equipment, and sells access to the network to end users. In this regard, levels of service must be discussed and agreed upon between each user and the MAN provider.
A Wide Area Network provides coverage far greater than a MAN is capable of providing. A WAN connects LANs and MAns, with an example of a WAN being the Internet. While a WAN, which operates similarly to a MAN, can span the globe, a MAN is only capable of spanning an area between 5 to 50 kilometers in range.

LAN, which stands for local area network, and WAN, which stands for wide area network, are two types of networks that allow for interconnectivity between computers. As the naming conventions suggest, LANs are for smaller, more localized networking — in a home, business, school, etc. — while WANs cover larger areas, such as cities, and even allow computers in different nations to connect. LANs are typically faster and more secure than WANs, but WANs enable more widespread connectivity. And while LANs tend to be owned, controlled and managed in-house by the organization where they are deployed, WANs typically require two or more of their constituent LANs to be connected over the public Internet or via a private connection established by a third-party telecommunications provider.

What is a LAN?

Local area networks (LANs) allow computers and devices that are near each other — and usually making use of the same switch or router — to connect to share files and complete tasks. Consisting only of everyday devices (e.g., desktops, laptops, tablets, printers), router and/or switch, and Ethernet cables or wireless cards, LANs are relatively inexpensive to set up and are commonly used in homes.

Ethernet cables, like the Cat5, Cat5e, and Cat6 and Cat6a, can be used to physically connect computers to the network. In the instances where fiber-to-the-home (or similar) is available, copper cabling may also be used at some point. Wi-Fi has become one of the most popular methods for wireless networking over a local network.

What is a WAN?

A wide area network (WAN) is used to connect computers that are not close to one another. It is possible — and almost always the case — that LANs are connected to WANs. This enables small home or office networks to connect to wider networks, such as those across state or country lines. Most WANs connect through public networks, like the telephone system, or via leased lines. The Internet, which connects computers all around the world, can be considered the largest WAN in existence.

Many interconnected LANs can become part of a larger WAN.

Speed

How fast data can be transferred over a LAN or WAN depends on the quality and data transfer capabilities of one's hardware and cables.

Having all the computers in a LAN physically connected to a router (or sometimes a switch) is the fastest way to transfer data between computers on a LAN. Moreover, using modern cables — Cat5e and better — will ensure the best data transfer speeds.

WAN speeds are affected by a number of factors. The equipment used in LANs that are connected to WANs affects a user's experience, as does the type of cabling used in the wide area network itself. WANs are typically slower than LANs due to the distance data must travel. For example, data transfers between two different states in the U.S. are faster than data transfers between London and Los Angeles. High-quality, copper submarine cables are used to help speed up data transfers between nations.

Wired vs. Wireless Speeds

Wirelessly transferring data via Wi-Fi significantly slows down transfer speeds, as typical wireless technology has a theoretical maximum speed that is lower than a wired connection's theoretical maximum speed.[1] Wireless connections will also likely feel less reliable, as wireless signals may experience interference from other devices' signals, from separating walls, from radio waves, etc. If consistent high speeds are needed within a LAN or WAN, particularly for business or gaming purposes, one should be physically connected to the network.

It is worth noting, however, that wireless technology has begun to "catch up" to wired technology in recent years. While the most reliable, high-speed connection is still one that is wired, wireless technology will likely feel just as comfortable for the average user.

Security

The most secure computer is one that is not connected to any network. LANs are safer than WANs, just by the nature and scope of a wide area network. The more people involved in interconnectivity, the greater chance there is for foul play. Using proper router security settings can help protect computers that connect to a network.

Which of the following network is used to connect cities states and countries?

Detailed Solution. 1) WAN: A wide area network(WAN) connects computers in different cities or countries.

Which type of network is used to connect two cities?

A metropolitan area network (MAN) is a computer network that connects computers within a metropolitan area, which could be a single large city, multiple cities and towns, or any given large area with multiple buildings. A MAN is larger than a local area network (LAN) but smaller than a wide area network (WAN).
