Features, Uses, and Difference Between LAN, WAN and MAN.

In today’s world, we are connected with many types of networks like LAN, WAN, and MAN through the internet.

These are the most popular and major network types that help us to share and access data and information digitally. Let’s know the LAN, WAN, and MAN with diagrams in detail.

Also Features and the differences between LAN, MAN, WAN, with the comparison chart.

1. LAN

The full form of LAN is the ‘Local Area Network. ‘ As the name suggests, it connects the computers by covering the local area within 10m to 1.5 km. Since it covers a small local area, you will find LAN in local places like offices, colleges, schools, groups of buildings, business organizations.

This network is managed and used by one person or one small organization. This network is used for resource sharing, data storage, document printing by connecting devices like printers, scanners, projectors, and other storage components.

In (LAN, WAN, and MAN), The LAN often connected via Ethernet cables and Wi-Fi also Token Ring and Fiber Distributed Data Interface, or FDDI, TCP/IP are the most common protocol that is used in this network.

When you share your internet connection with someone else, such sharing is also an example of LAN. The smallest LAN can be made up of only two computers.

The transmission rate of LAN ranges from 4Mbps to 16Mbps and can maximize up to 100 Mbps. For the interconnection of the host in LAN, we can use any type of network topology which meets the need of the network such as a bus or ring topology.

In a LAN, we can connect up to 1000 computers. Most LANs are used in wire connections. But nowadays, it is also being used without wire, i.e., in wireless connections. The bonus point of this network is its high speed, lower expenses, and security.

LAN (Local Area Network)

Features of LAN:

  1. The network capacity of a LAN is limited to a single room and small geographical areas like homes, small firms, and offices.
  2. The LAN has the advantage of high speed for data transfer.
  3. File transfer and recovery are more manageable in a LAN network because backup files are stored in a server.
  4. It has no connection with the external system, which ensures privacy.
  5. The LAN network is a private network, it doesn’t own by any government bodies.
  6. The network ranges from 1m to 1.5km.
Uses of LAN:

LAN often use as a local network at home for sharing data as well as on-campus of a college and school. Similarly, LAN is used as an intranet for business organizations via wifi.

Advantages of LAN

  • Resource Sharing: Unlimited data sharing via computer resources such as printers, DVD-ROM, modems, drives, and hard disks with local area networks; this reduces costs.
  • Software Applications Sharing: It is cheaper for each client to use the same software on the network instead of buying separately licensed software.
  • Easy and Cheap Communication: Communication will be handy and economical because data and messages can be easily transferred to networked computers.
  • Centralized Data: All the data of users is saved on the server’s database, one should not worry about losing the data and documents. Since there is a backup option to avoid such errors.
  • Security Level: Intermediate.
  • Internet Sharing: Local area network facilitates the sharing of a single Internet connection among all the users who are connected with the LAN.

Disadvantages of LAN

  • Setup Cost: Although LANs will save costs over time due to sharing computer resources, the initial cost of establishing a local area network is a bit expensive.
  • LAN Maintenance: Local area networks require a LAN administrator for handling software installation, wiring setup, hardware failures, or cable malfunctions.
  • Server Load: If the server is not very good, it cannot overload many computer connections, which can cause damage.
  • Security: There is a risk of insecurity because hackers can enter the system. Similarly, viruses, malware can also enter into a LAN it can damage all those that are connected.
  • Covers Limited Area: The local area network is limited covers only a small area such as a home, an office, a building, or a cluster of nearby buildings.

2. MAN

The Full form of MAN is the ‘Metropolitan Area Network.’ The WAN is a superior version of the LAN network, often used in cities and other locations covering a range of 5-60 km to transfer data at high speed.

MANs are high-speed connection networks because It is an extensive network by connecting several LANs into a single large network with a common bridge.

Under this network of MAN, two or more local area networks are connected. That bridge is called backbone lines which usually established by optical cable and twisted pair cables to boost data transfer speed.

This network connects all the prominent colleges, schools, and government offices, business organizations in the city. Thus, we can say that a MAN network is made up of multiple LANs.

The best example of a MAN is Cable TV situated in the middle of a city, as its cable spreads throughout the city, and the user uses the service through the cable network.

A big business organization has its own MAN. Through which it connects to a different branch. If such networks start being used on a college campus, they call it a CAN (campus area network).

MAN can be considered as a group of one or more LAN networks connected together through a single cable. RS-232, X-25, Frame Relay, and ATM are the common protocol practice for communication in MAN.

MAN (Metropolitan Area Network)

Features of MAN:

  1. The network coverage of MAN is more massive than LAN but smaller than WAN.
  2. It is bounded in large geographical areas such as a town, city.
  3. The data transmission speed is moderate.
  4. Its ownership can be public or private parties.
  5. The network ranges from 5 to 60km.
Uses of MAN:

MAN used in various government bodies, police stations, private firms that are situated within a city. The officers, employees can easily communicate either with each other or between their departments and branches in order to pass the important data and message quickly over this network without any need for the Internet connection.

Thus it provides various resource sharing over a large distance in the city than the LAN networks.

Advantages of MAN

  • MAN provides high-speed communication via fiber optic cable.
  • This provides a good backbone for large networks and gives WANs more access.
  • It serves many towns and cities and thus provides great inter-connectivity in large areas at a low cost.
  • The dual bus used in MAN helps in the transmission of data in both directions simultaneously.

Disadvantages of MAN

  • MAN needs more cables from joining connections from one place to another.
  • Greater will be the cable length, the more will be the cost of establishing the MAN.
  • At such a big distance anyone can hack the network. One can’t put security at each point of the network in the widespread areas, hence it becomes easier for unwanted people to access it for their own benefits.
  • It is difficult for the system to protect from the graphical areas of hackers and industrial espionage.

3. WAN

A WAN full-form is ‘Wide Area Network. ‘ A WAN is used to connect computers that are not close to one another. It is the collection of many LANs with a much more extensive range than LAN and MAN.

In LAN, WAN, and MAN, the WAN network’s geographical periphery is more widespread such as a network of systems spread across the entire city, country, or even continent.

This network connects has similar structures, as LANs and MANs. Most WANs are public networks, like the phone line and satellites, telephone systems, or leased lines.

Generally, fiber optic cable is used as a medium for transmission in WAN. This network works on physical, data-link, and network layers of the OSI Reference Model.

Devices involved for the transmission of data, images, video, big database, and files in the connection of WAN more diversified, ranging from routers to switches, bridges, firewall modems, and so on.

Some of the most common WAN protocols in use today are Frame Relay, X-25, Integrated Services Digital Network, or ISDN, and Point-to-Point Protocol, or PPP.

An example of the largest WAN is the Internet. Through the Internet, people can connect from one place or other computers or users anywhere in the world. It is implemented by a public broadcasting system.

WAN (Wide Area Network)

Features of WAN:

  1. It is generally used for voice and data for mobile and landline phone applications.
  2. A large number of people can communicate with one another in this single network.
  3. Its data transmission speed fluctuating sometimes slow or even very fast.
  4. The network range or coverage area of ​​a WAN is more massive, from which we can transfer the data across the world.
Uses of WAN:

The WAN networks are used for military services. There is a satellite method of transmission is used in this setup. WAN is used in this field for the communication and operation of the military with high security.

Airlines and Railways use WAN networks for booking tickets from anywhere in the country. The is done because client nodes are situated all over the country and are connected to a centralized server to one network.

Advantages of WAN

  • It covers a large geographic area so that long-distance businesses and companies are able to connect on a single network.
  • Shares software and resources with connecting workstations.
  • Messages can be sent very fast to someone else on the system, the rate of transmission is very high even if we send large-sized files of more than 10 MB.
  • Everyone on the network can use the same data. This avoids problems where some users may have older versions of information than others.
  • All clients associated through WAN will stay in synchronization with each other constantly, accordingly, there will be no odds of a correspondence hole between them.

Disadvantages of WAN

  • A good firewall is needed to prevent anonymous hackers from hacking the data and disrupting the network.
  • Setting up a network is very expensive, slow, and complicated. The more comprehensive the system, the more expensive it.
  • There is a need to appoint technicians and supervisors for the full-time maintenance of connections.
  • There is a need to spend many expenses for security purposes.
