In computer networking, two of the most common terms you’ll encounter are LAN and WAN. These terms describe different types of networks based on size, purpose, and geographical coverage. Understanding the difference between LAN and WAN is essential. This knowledge is useful when you’re setting up a home network. It is also important for managing the office IT infrastructure. Additionally, knowing this helps when learning how the internet works.

What is a LAN (Local Area Network)?
A LAN, or Local Area Network, is a network that connects devices within a limited area such as a home, office, school, or building.
- Devices in a LAN might include computers, printers, IP cameras, switches, and routers.
- All devices share the same internal network and can easily communicate with each other.
- LANs are typically fast and have low latency since everything is nearby.
🔹 Example of a LAN:
In your home, your smartphone, laptop, smart TV, and printer all connect to your MikroTik router. They form a LAN—each device gets a local IP (like 192.168.88.5) and can share files or stream content between them.
What is a WAN (Wide Area Network)?
A WAN, or Wide Area Network, is a network that connects devices over a large geographical area, often spanning cities, countries, or even continents.
- The most common example of a WAN is the internet itself.
- WANs are typically used to connect multiple LANs together.
- WAN connections often involve telecom providers or ISPs (Internet Service Providers).
🔹 Example of a WAN:
Your home router connects to your ISP through the WAN port. It gets access to the internet. You’re using a WAN. If you work remotely and connect to your company’s network in another city, that’s another form of WAN in action.
Key Differences Between LAN and WAN
| Feature | LAN (Local Area Network) | WAN (Wide Area Network) |
|---|---|---|
| Coverage | Small (home, office) | Large (city, country, global) |
| Speed | Typically faster | Typically slower (depends on ISP) |
| Ownership | Private (you manage it) | Often public or managed by ISPs |
| Examples | Home/office network | Internet, company branch connections |
Both LAN and WAN play crucial roles in how we connect and communicate digitally. While LAN handles your local connections—like devices in your home—WAN connects you to the world through your ISP. Understanding the difference helps in setting up, troubleshooting, and managing your network more effectively.
