A Simple Guide to Network Types - PAN, LAN, MAN, and WAN

📝 Cheat Sheet

PAN, LAN, MAN, and WAN

Networks are grouped by size. A PAN covers a few feet around one person. A LAN covers one building. A MAN covers a city. A WAN covers a country or the entire world.

A computer network connects devices so they can share information. We can group networks into four main types based on their size. These types are:

  1. PAN
  2. LAN
  3. MAN
  4. WAN
❓ Pop Quiz

PAN (Personal Area Network)

A PAN is a tiny network for one person’s devices. It connects things that are very close to each other, like on your desk or in your pocket.

A PAN is a network just for you.

Examples of PAN

  • Connecting a smartphone to Bluetooth headphones.
  • Using a wireless mouse with a computer.
  • Syncing a smartwatch with a phone.
  • Connecting a phone to a car’s stereo.
  • Sending a file from a laptop to a phone using a USB cable.

More About PAN

  • How big is it? It covers a very small area, just a few feet.
  • How fast is it? It has good speed for personal devices and costs very little.
  • How is it used? It connects your personal gadgets together.

Answer

LAN covers one building. WAN covers a country or the world.

LAN is fast and cheap. WAN is slower and costs more.

Example: your school Wi-Fi is a LAN. The Internet is a WAN.

LAN (Local Area Network)

A LAN is a network that covers a small, local area. It connects devices in a single building or a small group of buildings.

A LAN connects devices in one place, like a home or school.

Examples of LAN

  • The Wi-Fi network in a home.
  • All the computers in a school’s computer lab.
  • The printers and computers connected in a small office.
  • The public Wi-Fi at a coffee shop.
  • The network at a local library.

More About LAN

  • How big is it? It covers a single building or a small campus.
  • How fast is it? It is very fast and does not cost much to set up.
  • How is it used? It is used to share files, printers, and the internet in one location.

MAN (Metropolitan Area Network)

A MAN is a network that is bigger than a LAN. It can connect computers across a whole city or a very large university campus.

A MAN is a network for a whole city.

Examples of MAN

  • A cable TV network that serves an entire city.
  • A university’s network that connects different campuses in a city.
  • A network connecting all government buildings downtown.
  • A chain of local hospital branches that share information.
  • A city-wide public Wi-Fi network.

More About MAN

  • How big is it? It is larger than a LAN and can cover an entire city.
  • How fast is it? It is faster than a WAN but slower than a LAN.
  • How is it used? It connects different LANs together across a city.
❓ Pop Quiz
A student connects Bluetooth headphones to their phone before class. Which type of network is being used?

WAN (Wide Area Network)

A WAN is the largest type of computer network. It connects devices over very large areas, like a country or even the entire world.

A WAN connects networks across the globe. The Internet is a WAN.

Examples of WAN

  • The Internet is the biggest WAN in the world.
  • A bank’s network that connects all its branches in a country.
  • A company’s network that connects its offices in different countries.
  • A military’s network that connects bases around the world.
  • An online gaming network for players in different countries.

More About WAN

  • How big is it? It can cover a country or the whole world.
  • How fast is it? It is usually slower than a LAN and costs a lot to manage.
  • How is it used? It is used to connect different LANs over long distances.
