how many types of network in networking?

 LAN, MAN and WAN are the 3 types of network in network marketing.


Local Area Network (LAN) –

LAN or Local Area Network connects network devices in such a way that personal computer and workstations can share data, tools and programs. The group of computers and devices are connected together by a switch, or stack of switches, using a private addressing scheme as defined by the TCP/IP protocol. Private addresses are unique in relation to other computers on the local network. Routers are found at the boundary of a LAN, connecting them to the larger WAN.


Metropolitan Area Network (MAN) –

MAN or Metropolitan area Network covers a larger area than that of a LAN and smaller area as compared to WAN. It connects two or more computers that are apart but resides in the same or different cities. It covers a large geographical area and may serve as an ISP (Internet Service Provider). MAN is designed for customers who need a high-speed connectivity. Speeds of MAN ranges in terms of Mbps. It’s hard to design and maintain a Metropolitan Area Network.


The fault tolerance of a MAN is less and also there is more congestion in the network. It is costly and may or may not be owned by a single organization. The data transfer rate and the propagation delay of MAN is moderate. Devices used for transmission of data through MAN are: Modem and Wire/Cable. Examples of a MAN are the part of the telephone company network that can provide a high-speed DSL line to the customer or the cable TV network in a city.


Wide Area Network (WAN) –

WAN or Wide Area Network is a computer network that extends over a large geographical area, although it might be confined within the bounds of a state or country. A WAN could be a connection of LAN connecting to other LAN’s via telephone lines and radio waves and may be limited to an enterprise (a corporation or an organization) or accessible to the public. The technology is high speed and relatively expensive.


There are two types of WAN: Switched WAN and Point-to-Point WAN. WAN is difficult to design and maintain. Similar to a MAN, the fault tolerance of a WAN is less and there is more congestion in the network. A Communication medium used for WAN is PSTN or Satellite Link. Due to long distance transmission, the noise and error tend to be more in WAN.


But for network marketing business there should be a network marketing software is needed.

The most common categories of computer network are described in details below by our experts:

WAN (Wide Area Network)
WAN is defined as the computer network that covers a broad area which may span across provinces and even whole country. In the sector of telecommunications, this type of system is utilized. This network is of extreme high speed. So the users have to spend a huge amount of money to get the services from this network.
Government entities, business organizations and other education facilities use WAN to get connected and transmit data to each other. Different technologies are used to develop the wide area network links from integrated telephone lines, radio wave transmission and the optical fiber. The speed of the WAN has increased radically in the last few decades. From 110 bits per second in the year 1960 to up to 100 G/bits per second now, the speed has improved exponentially.
LAN (Local Area Network)
A network system installed in a building and operated under single administrative system is known as LAN. Generally, this type of network is used in organization’s offices, schools, colleges/universities, etc.
Usually, the LAN has a server of its own which has its own applications and storage systems that are shared among the users. From two to a few hundred, the number of users within the LAN network can vary. Today, Ethernet and Wi-Fi are the most common forms of LAN usage. A wireless LAN is always preferred to wired LAN due to its effectiveness, flexibility and cost. Simple LANs comprises of two to three switches which are connected to the router or modem for internet access. A complex LAN consists of several switches which uses a spanning tree protocol to prevent loops and manage more volumes of data transmission.
Internet
This network is mostly used in recent private, public, business, academic and government networks connected and guided by wireless and fiber-optic technologies. Computer network assignment help experts highlight internet as a network of global exchange connected by network system that uses TCP/IP to transmit data.
It is also referred to as Internet Area Network which is envisioned as the ideal networking model for the future. It connects all the endpoints through the public web, enabling the transmission of data and exchanging information possible without getting bound to a physical location. The rise of Internet Area Network is based on cloud computing. In the last one decade, high capacity networks and peer-to-peer architecture have paved the way for the popularity of internet networking.
MAN (Metropolitan Area Network)
This type of network facilities equips the whole city such as cable TV network. It can be used in various forms like Ethernet, Token-ring, ATM or FDDI. With accordance to the area of coverage, a MAN network covers larger area than LAN but smaller than WAN. MAN links generally use microwave, radio or infra-red laser transmission to connect between two LANs.
MANs are used to build high speed network for cities and towns which is effective due to its medium range. The network of MAN can extend up to 40 kilometers maintaining its speed and effectiveness. These days MAN networks work on Distributed Queue Dual Bus (DQDB) with IEEE 802.6 standard of data communication giving a speed of transmission up to 155 Mbps.

Before knowing about the types of networks, it is necessary to know what is network. When two and more computers are connected together, the medium which is used to connect them is called network.


Now coming to your question, there are five types of network in networking.

1. PAN (Personal Area Network)

types-of-network-letsdiskuss

The range of this type of network is very small. PAN is usually used within a home, and that’s why it is known as Personal Area Network. With a PAN network operating in a building, one can connect the computers of that building with each other and other gadgets like mobile phones and tablets can also be connected through it.

2. HAN (Home Area Network)

Several people using the same network to connect multiple devices with a computer is known as Home Area Network or HAN. Previously connected through modem or wire, now a days this is done with Wi-Fi.

3. LAN (Local Area Network)

This provides you with networking options within a local area. Schools, offices, airports, etc., use LAN. The protocol used for LAN is known as Ethernet.

4. MAN (Metropolitan Area Network)

With LAN, you can connect only two or more computers with each other, but with MAN, more computers can be connected. MAN is connected with high speed fiber optic wires through switches and hubs. MAN is greater than LAN but smaller than WAN.

5. WAN (Wide Area Network)

WAN is used for very big areas. Leased line connection is used to connect computers through WAN. Leased line is a telephone line which connects computer with ISP server.
