Local-area network (LAN): A network infrastructure that provides access to users and end devices in a small geographical area.
Wide-area network (WAN): A network infrastructure that provides access to other networks over a wide geographical area.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 endpoints in a small geographical area.
Storage-area network (SAN): A network infrastructure designed to support file servers and provide data storage, retrieval, and replication. It involves high-end servers, multiple disk arrays (called blocks), and Fibre Channel interconnection technology.
