Types of Computer Network | LAN, PAN, MAN & WAN

Computer Network Types

An electronic network could be a cluster of laptops connected to every different that allows the pc to speak with another computer and share their resources, data, and applications.

A network is often categorized by its size. A network is principal of 4 types:

·         LAN (Local Space Network)

·         PAN (Personal space Network)

·         MAN (Metropolitan space Network)

·         WAN (Wide Space Network)

LAN (Local Area Network)

• Local space Network may be a cluster of computers connected to every different in a very tiny space like a building, office.

• LAN is employed for connecting 2 or a lot of personal computers through a communication medium like twisted combine, coax, etc.

• It is more cost-effective because it is constructed with cheap hardware like hubs, network adapters, and local area network cables.

• The data is transferred at an especially quicker rate in the native space Networks.

• Local space Network provides higher security.

PAN (Personal Area Network)

• A personal space Network may be a network organized among a private person, usually among a variety of ten meters.

• Personal space Network is employed for connecting the pc devices of non-public use is thought as Personal space Network.

• Thomas Zimmerman was the primary analysis human to bring the thought of the private space Network.

• Personal space Network covers a district of thirty feet.

• Personal computer devices that are wont to develop the private space network are the portable computer, mobile phones, and media players and play stations.

There are two types of Personal Area Networks:

·         Wired Personal space Network

·         Wireless Personal space Network

Wireless Personal space Network:

 Wireless Personal space Network is developed by mere mistreatment of wireless technologies like wireless fidelity, Bluetooth. It’s an occasional varied network

Wired Personal space Network: Wired Personal space Network is made by victimization the USB.

Examples of Personal space Network:

Body space Network: A body space Network could be a network that moves with someone. As an example, a mobile network moves with someone. Suppose someone establishes a network association then creates a reference to another device to share the knowledge.

Offline Network: An associate in nursing offline network will be created within the house, therefore it's additionally referred to as a home network. A home network is meant to integrate the devices like printers, computers, TV however they're not connected to the net.

Small Home Office: it's accustomed to connect a range of devices to the net and to a company network employing a VPN

MAN (Metropolitan Area Network)

• A metropolitan space network could be a network that covers a bigger geographical area by interconnecting a unique local area network to create a bigger network.

• Government agencies use MAN to attach to the voters and personal industries.

• In MAN, numerous LANs are connected to every alternative through a workplace line.

• The most widely used protocols in MAN are RS-232, Frame Relay, ATM, ISDN, OC-3, ADSL, etc.

• It has a better vary than native space Network (LAN).

Uses of Metropolitan Area Network:

• MAN is employed in communication between the banks in a very town.

• It will be employed in associate Airline reservations.

• It will be employed in a school inside a town.

• It may be used for communication within the military.

WAN (Wide Area Network)

• A Wide Space Network may be a network that extends over an outsized geographic area like states or countries.

• A Wide Space Network is kind of larger network than the local area network.

• A Wide Space Network isn't restricted to one location, however, it spans over an outsized geographic area through a phone line, fiber optic cable, or satellite links.

• The internet is one of the largest WANs in the world.

• A Wide Space Network is widely employed in the sector of Business, government, and education.

Examples of Wide Area Network:

Mobile Broadband: A 4G network is widely used across a neighborhood or country.

Last-mile: A telecommunication company is employed to produce web services to the purchasers in many cities by connecting their homes with fiber.

Private network: A bank provides a non-public network that connects the forty-four offices. This network is formed by exploiting the phone-hired line provided by the telecommunication company.

Advantages of Wide Area Network:

Following square measure the benefits of the Wide space Network:

Geographical area: A good space Network provides an outsized geographic area. Suppose if the branch of our workplace is in an exceedingly completely different town then we will connect with them through WAN. The net provides a chartered line through that we will connect with another branch.

Centralized data: Just in the case of the WAN network, knowledge is centralized. Therefore, we have a tendency to ought not to get emails, files, or duplicate servers.

Get updated files: Software system firms work on the live server. Therefore, the programmers get the updated files inside seconds.

Exchange messages: In an exceedingly WAN network, messages square measure transmitted quickly. The net application like Facebook, WhatsApp, and Skype permits you to speak with friends.

Sharing of software package and resources: In the WAN network, we will share the software package and different resources sort of a drive, RAM.

Global business: We will do the business over the net globally.

High information measure: If we tend to use the hired lines for our company then this provides the high bandwidth. The high information measure will increase the info transfer rate that successively will increase the productivity of our company.

Disadvantages of Wide Area Network:

The following are the disadvantages of the Wide space Network:

Security issue: A WAN network has a lot of security problems as compared to {lan|local area network|LAN|computer network} and MAN network as all the technologies are combined along that makes the protection drawback.

Needs Firewall & antivirus software: The information is transferred on the net which may be modified or hacked by the hackers, therefore the firewall must be used. Some folks will inject the virus into our system therefore antivirus is required to guard against such a deadly disease.

High Setup value: The associate in nursing installation cost of the WAN network is high because it involves the buying of routers, switches.

Troubleshooting problems: It covers an outsized space therefore fixing the matter is tough.
