Network types: LAN, WAN, MAN
LAN (Local Area Network):
- Scope: Covers a small area like a home, office, or school.
- Speed: Fast because devices are close together.
- Example: Connecting computers and printers in an office.
MAN (Metropolitan Area Network):
- Scope: Covers a city or a large campus.
- Speed: Moderate, faster than WAN but slower than LAN.
- Example: A city’s public Wi-Fi or a university connecting different campuses.
WAN (Wide Area Network):
- Scope: Covers large areas like countries or continents.
- Speed: Slower due to long distances and complex infrastructure.
- Example: The Internet is the biggest WAN.
Here’s a comparison table for LAN, MAN, and WAN:
| Aspect | LAN (Local Area Network) | MAN (Metropolitan Area Network) | WAN (Wide Area Network) |
|---|---|---|---|
| Coverage Area | Small (home, office, school) | Medium (city, large campus) | Large (country, continent, global) |
| Speed | High | Moderate | Lower compared to LAN and MAN |
| Ownership | Private (individual or organization) | Can be private or public | Usually public or shared among providers |
| Cost | Low | Moderate | High (due to infrastructure) |
| Example | Office network, home Wi-Fi | City-wide Wi-Fi, university networks | The Internet, international company networks |
| Reliability | Highly reliable | Reliable | Less reliable due to distance and complexity |
| Data Transfer Rate | Fastest | Moderate | Slowest compared to LAN and MAN |
