What Are the Four Types of Network? 
The most common types of networks include Local Area Network (LAN) and Wide Area Network (WAN). The other two main types of network are Metropolitan Area Network (MAN) and Wireless LAN (WLAN), with Wireless WAN (WWAN) also an offshoot of a similar principle. Here's a brief breakdown of each of the four main types of network.
Local Area Network.
Typically the most common type of network you'll encounter, a Local Area Network, involves connecting computers in a relatively small area. That area can be your home, an office, or school, amongst other locations. The devices can connect either via an Ethernet cable or through Wi-Fi. 
W ide Area Network.
This type of network spans a large geographic area such as a city, state, or country. The internet itself is considered the largest Wide Area Network globally, with Wide Area Networks making it possible for smaller Local Area Networks to connect to it. Businesses may also have a Wide Area Network to link their many offices together.

• 
  Metropolitan Area Network. A Metropolitan Area Network is bigger than a LAN but smaller than a WAN. Large corporations or government bodies use it to link together different resources across a business. 
  
• 
  Wireless LAN.
  

A wireless LAN works much like a Local Area Network, but it does so through wireless connections such as Wi-Fi or Bluetooth rather than using Ethernet cables. 
Why Do I Need a Network?
Likely, the only network you'll come across knowingly daily is a home network, aka a Local Area Network (LAN). Not everyone needs a home network. If you only have one computer and no other devices you want to take online or share resources with, there's no need for a network. 
However, most people now have their own LAN setup at home with multiple devices connected to it. It's important to know if wired or wireless is best for your home, or a combination of both, as well as understand how to set up a home network.
