Networks are essential for connecting various devices and facilitating communication, data sharing, and resource allocation. They vary in size, range, and complexity, catering to different needs and scenarios. Here's an overview of the various types of networks:

Personal Area Network (PAN)

A PAN is a small network that typically involves a wireless connection within a personal space, like connecting a Bluetooth headset to a smartphone. It's ideal for individual use and has a limited range, usually not exceeding 10 meters.

Local Area Network (LAN)

A LAN connects devices within a limited area, such as a home, office, or school. It can be wired or wireless (WLAN), with the latter commonly known as Wi-Fi. LANs are suitable for sharing resources like printers and files within a single building or closely situated buildings.

Campus Area Network (CAN)

A CAN is larger than a LAN but smaller than a metropolitan area network (MAN). It's used to link multiple LANs within a specific area like a university campus or corporate park. CANs facilitate communication and resource sharing across different departments or buildings within the same organization.
