Top 5 Types Of Network

Types of Networks

Types of Network (based on area and based on architecture).

Today world is connected with computer networks. Every work and activity is done through a computer network due to the network such a big world has been created today.

Types of Network

With the help of computer networks today a big world change into a small village. This is possible by the computer network. A computer network is defined as the connection of at least two computer systems, either by a wired and wireless connection.

In other words, a computer network consists of two or more computers that are linked in order to share resources such as printers exchange files, or allows electronic communication.

The computer on a network may be linked through cables, telephone lines, radio waves, satellites, infrared light webcams.

Similarly, networking is an exchange of information and ideas among people with a common profession or special interest, usually in an informal setting. Networking often being with a single point of common ground.


Mainly computer networks are two types :

  • Area
  • Architecture

Similarly, there are three types of networks based on area and two types of networks based on Architecture.


On the basis of Area, There are Four types of network

Types of Network
  • LAN (Local Area Network )
  • MAN (Metropolitan Area Network)
  • WAN(Wide Area Network)
  • PAN(Personal Area Network)

What are the four types of network-based on the area?

The four types of networks based on the area are:
LAN (Local Area Network )
MAN (Metropolitan Area Network)
WAN(Wide Area Network)
PAN(Personal Area Network)


Local Area Network(LAN)

What is LAN?

A local area network is a group of computers connected with each other in a small place such as a school, Hospital, Building, Office etc Especially one with a radius of less than 1km.

Types of Networks

These types of Net has a limited scope and cost of operating LAN’s are owned controlled and managed by a single person or organization.

 LAN’s can be two types:-

Wired LAN it is connected by cable to physically connect all computer on the network. They can also be created using coaxial cables, phone lines, power lines. Wireless LAN’s uses radio wave for communication.

LANs,s have higher data transfer processes, a small geographic range and there is no need for leased telecommunication lines.

What are the advantages of LAN?

The advantages of LAN are:

  • Resource Sharing
  • Software application sharing
  • Easy and cheap Communication
  • Data security
  • Internet sharing

What are the disadvantage of LAN?

The disadvantages of LAN are:

  • High setup cost
  • Data Security Threat
  • Cover Small Area

Metropolitan Area Network(MAN):-

What is MAN(Metropolitan Area Network)?

A metropolitan area network is a computer network that interconnected users with computer resources in a geographic region of the size of the metropolitan area.

Types of Networks

MAN is a network that interconnects computers and other devices in an area larger than LAN but smaller than the area covered by WAN.

These types of networks can connect in a city, Community to form a single large network. The size of these types of networks lies in between LAN and MAN cover an area of 5-50 km.


Advantages of MAN

  • Large geographical area cover as compared to LAN
  • High-speed Data connectivity.
  • Bandwidth could be easily accessed within MAN’s.
  • It mainly used fibre optic cable.
  • It supports voice communication.

Disadvantages of MAN

  • It is hard to design and maintain MAN.
  • MAN is less fault-tolerant.
  • It is costlier to implement.

Wide Area Network

What is WAN(Wide Area Network)?

A wide area network is telecommunications networks covering the largest geographic area.

Types of Networks

A wide area network is telecommunications networks covering the largest geographic area. The internet is the biggest example of a wide area network and has influenced our daily lives all around the world.

Wide area networks are connected to local area networks to enable computers to share, send, and access information on a large scale.

If it weren’t for a wide-area network it wouldn’t be possible to communicate with the whole world.


Advantage of WAN

  • Cover large geographical area.
  • Centralized data.
  • Get information about the world easily.
  • Exchange massage.
  • Global business.

The disadvantage of WAN:-

  • The Data Transfer rate is lower than other networks.
  • The error rate is higher than another network.
  • It is very complex to design a WAN.
  • Security problem.
  • Needs a firewall and antivirus.
  • Maintenance issue.
  • There some optional Networks available in the world I explain shortly about this network.

Personal area network (PAN)

What is PAN(Personal Area Network)?

The smallest and most basic type of network, a PAN is made up of a wireless modem, a computer or two, phones, printers, tablets, etc.

Types of Networks

These types of networks are typically found in small offices and are managed by one person or organization from a single device.


Types of Networks

Wireless area network (WLAN)

What is WLAN(Wireless Local Area Network)?

WLAN is a wireless computer network that usually links two or more devices using wireless communication to form a local area network(LAN) within a limited area such as a home, school, office building.

These types of networks also have the same functions as a LAN, WNANs make use of wireless network technology, such as wi-fi,  Bluetooth, etc.


Types of Networks

Storage area network (SAN)

AS a dedicated high-speed network that connects shared pools of storage. SAN can be accessed in the same fashion as a drive attached to a server.


Types of Networks

System area network(SAN)

This term is fairly new within the past two decades, it is used to a relatively local area network that is designed to provide high-speed connection in the server-to-server applications.

The computers connected on a SAN operate as a single system at very high speeds.


Based on Architecture, the two types of network architecture are:-

Types of Networks
  • Peer-to-Peer network
  • Client/server network

Peer–to–peer network architecture

Types of Networks

Peer-to-peer network architecture is a commonly used computer networking architecture in which each workstation or node has the same capabilities and responsibilities.

These types of networks are often compared and contrasted to the classic client /server architecture, in which some computers are dedicated to serving others. Every computer in the p2p network is treated equally and can send as well as receive them directly.

p2p network cannot be under heavy load. These types of networks or their architecture are commonly used for file sharing and chatting in real-time. its type of computer network connected every computer to every computer.

The main advantage of the p2p network is, Does not need a Server because individual workstations are used to access the file. The main disadvantage of a p2p network is, files and folders cannot be centrally backup.


Client-server network architecture

Types of Networks

A client-server network is a medium through which clients access resources and services from a central computer, via either a local area network or a wide area network.

In a simple, these types of the network have one main server like modem, wi-fi which operates other computer or devices.

The main advantage of these types of networks is the greater security of the network because there is a main server that controls all devices and computers.

The Main Disadvantage of These types of networks if the main server crashed, the complete network break down because all computer connected with the main server.

Conclusion

Even we have various types of the network but overall each of the networks has the purpose to connect many computers and make the environment to access communication and sharing resource and convert the whole world into the global village without territorial barrier.
