  1. Local Area Network (LAN): A LAN covers a limited geographical area, typically within a building or a campus. It allows devices within its boundaries to communicate directly with each other at high speeds, making it ideal for small to medium-sized organizations.
  2. Wide Area Network (WAN): WANs cover larger geographical areas, such as cities, countries, or even global distances. They connect multiple LANs and facilitate communication between devices across vast distances. The internet is a prime example of a worldwide WAN.
  3. Metropolitan Area Network (MAN): A MAN lies between LAN and WAN in terms of geographic scope, covering an entire city or a large campus. It provides high-speed connectivity within a metropolitan area.
  4. Wireless Local Area Network (WLAN): A WLAN is a type of LAN that uses wireless communication technologies, such as Wi-Fi, to connect devices without the need for physical cables.
  5. Campus Area Network (CAN): A CAN typically covers a university campus or a corporate headquarters, connecting various buildings and facilities.
  6. Personal Area Network (PAN): A PAN is a network formed by personal devices, like smartphones, laptops, and wearable devices, within the range of an individual person.
