Types of Networks


Network infrastructures can vary greatly in terms of:

  • Size of the area covered

  • Number of users connected

  • Number and types of services available

  • Area of responsibility
The figure illustrates the two most common types of network infrastructures:

  • Local Area Network (LAN) - A network infrastructure that provides access to users and end devices in a small geographical area, which is typically an enterprise, home, or small business network owned and managed by an individual or IT department.

  • Wide Area Network (WAN) - A network infrastructure that provides access to other networks over a wide geographical area, which is typically owned and managed by a telecommunications service provider.
Other types of networks include:

  • Metropolitan Area Network (MAN) - A network infrastructure that spans a physical area larger than a LAN but smaller than a WAN (e.g., a city). MANs are typically operated by a single entity such as a large organization.

  • Wireless LAN (WLAN) - Similar to a LAN but wirelessly interconnects users and end points in a small geographical area.

  • Storage Area Network (SAN) - A network infrastructure designed to support file servers and provide data storage, retrieval, and replication.
