Types of Network | 11 Types of Network | Definition
Before we start the types of network, you must know What is Network Security?
Here we talk about types of network and definitions in details. There are 11 types of network. These are the 11 types of the network we’re using these days mostly.
- Personal Area Network (PAN).
- Local Area Network (LAN)
- Wireless Local Area Network (WLAN)
- Campus Area Network (CAN)
- Metropolitan Area Network (MAN)
- Wide Area Network (WAN)
- Storage-Area Network (SAN)
- System-Area Network (also known as SAN)
- Passive Optical Local Area Network (POLAN)
- Enterprise Private Network (EPN)
- Virtual Private Network (VPN)
1. Personal Area Network
Personal area network (PAN) is made up of wireless modem or smartphones, electronic devices such as a computer or two. This type of networks mostly found in a small building. This type of network is managed by a person or an organization for their small businesses. Such as USB or firewire (in case of wired), wireless: Bluetooth, infrared, ZigBee etc. PANs range is typically a few meters only.
2. Local Area Network
This network covers small fixed areas such as a room, a building, an office or in a school. We can use a large number of computers in a LAN but it is restricted to a small geographical area. By creating a LAN, we can share resources such as hardware and software and transfer information between the computers. We can create a LAN, by using cable or wireless media.
3. Wireless Local Area Network (WLAN)
WLAN is using a wireless computer network which is links two or more than two devices through a wireless communication. The device to form a Local Area Network so it’s called Wireless Local Area Network (WLAN). It can be used within a small and limited area only for example Computer Laboratory, College, a small office building, school, home etc.
4. Campus Area Network (CAN)
Somewhere CAN (Campus Area Network) is also known as a corporate area network (CAN). It is a network of multiple interconnected LANs in a limited geographical area. Campus Area Network or Corporate Area Network is smaller than WAN or MAN. If you think what is WAN or MAN? We explained it below.
5. Metropolitan Area Network (MAN)
It is far larger than a LAN and smaller than a WAN. It covers a larger geographical area such as a university, an entire city, a valley, a district, a zone or a whole country. This type of network is prepared by connecting several LANs in different locations. To form a MAN, several LANs are connected through a telephone line, optical fiber cable or wireless communication media. The MAN network usually exists to provide connectivity to local ISPs, cable tv, or large corporations.
6. Wide Area Network (WAN)
This is the largest network and can interconnect networks throughout the world. It is not restricted to a geographical location. The Internet is an example of a worldwide public WAN. To form a WAN, several LANs and MANs are connected through the satellite links or microwave system. This technology is high speed and very expensive to set up.
7. Storage-Area Network (SAN)
SAN (Storage Area Network) is a type of high speed dedicated network or subnetwork which interconnects and presenting sharing pools of storage devices to multiple servers. It moves storage resources to the user network and reorganizes them into independent, high-performance network.
8. System-Area Network (also known as SAN)
System Area Network is basically designed for high-speed interconnection in cluster environments (server to server, multiprocessing system (processor to processor) and storage area networks (SANs). A SAN uses internet protocol (IP) address connection that assigned by TCP/IP.
9. Passive Optical Local Area Network (POLAN)
Passive Optical Local Area Network (POLAN) is making many advantages of optical fiber, it can be higher bandwidth. It is newly structured to replacing old structured cables.
10. Enterprise Private Network (EPN)
Enterprise Private Network (EPN) is made for a business to interconnect each other share resources such as shops, business sites, offices etc. It mostly used for business purposes.
11. Virtual Private Network (VPN)
Virtual Private Network (VPN) is an advanced technology which is an encrypted connection over less secure networks for example internet. It can hide your real location in real time. For example, windows VPN connection can use PPTP (packets to encapsulate) and send private traffic, such as it uses manual IP address.
