There are different types of Network such as
1. Personal Area Network (PAN): - These types of network are typically found in small offices or residences and managed by one person or organization from a single device.
2. Local Area Network (LAN): - It connects groups of computers and peripherals. Enterprises typically manage and maintain LANs.
3. Wireless Local Area Network (WLAN): - Functioning like a LAN. It make use of wireless network technology, such as WiFi. It may be Personal or Organizational.
4. Campus Area Network (CAN): - This is larger than LAN. These types of networks are typically seen in universities, school and small businesses.
5. Metropolitan Area Network (MAN): - These types of networks are larger than LAN but smaller than WAN. Typically covers a town or city.
6. Wide Area Network (WAN): - These types of networks are larger than LAN and MAN. This covers City, State, Country, etc. The internet is the most basic example of WAN, connecting all computers together around the world.
7. Storage Area Network (SAN): - As a dedicated high-speed network that connects shared pools of storage devices to several servers. These types of networks don't rely on a LAN or WAN.
8. System Area Network (SAN): - This term is fairly new within the past two decades. It is used to explain a relatively local network that is designed to provide high speed connection in server-to-server applications, storage area networks and processor-to-processor application.
9. Passive Optical Local Area Network (POLAN): - It can be integrated into structured cabling to overcome concerns about supporting traditional Ethernet protocols and network applications such as PoE (Power over Ethernet). It uses optical splitters to split an optical signal from one strand of single mode optical fiber into multiple signals to serve users and devices.
10. Enterprise Private Network (EPN): - These types of network are built and owned by business that want to securely connect its various locations to share computer resources.
11. Virtual Private Network (VPN): - By extending a private network across the internet, a VPN lets its users send and receive data as if their devices were connected to the private network - even if they're not. Through a virtual point to point connection, users can access a private network remotely.
