What are Man and Wan?

MAN (Metropolitan Area Network)

A MAN (Metropolitan Area Network) is a network that spans a city or a large campus, connecting multiple local area networks (LANs). It is larger than a LAN but smaller than a wide area network (WAN).

Key Features of MAN

• Geographic Range: Covers a city or metropolitan area (e.g., connecting offices across a city).
• Ownership: Typically owned and managed by a single organization or a consortium.
• Speed: Offers high-speed connections suitable for sharing resources and services within the area.

Use Cases

• Connecting branch offices within a city.
• Providing internet access in public places like parks or universities.

WAN (Wide Area Network)

A WAN (Wide Area Network) is a network that spans large geographic areas, such as countries or continents. It connects multiple LANs and MANs, allowing data exchange over long distances.

Key Features of WAN

• Geographic Range: Covers vast areas, often worldwide (e.g., the internet is the largest WAN).
• Ownership: Typically owned by multiple entities, including ISPs and telecom companies.
• Speed: Can vary based on infrastructure, with fiber optics offering higher speeds.

Use Cases

• Connecting offices located in different cities or countries.
• Supporting global communication and data exchange.

Key Differences Between MAN and WAN

• Coverage Area: MAN covers cities; WAN covers much larger areas like countries or continents.
• Ownership: MAN is usually owned by a single organization, whereas WAN is a shared infrastructure.
• Speed and Latency: MAN often provides higher speeds with lower latency than WAN due to its smaller range.
