9. DISANTAGES

   • Although the LAN will save cost over time due to shared computer resources but the initial setup costs of installing Local Area Networks is high. This is because any organization that will setup a network, will have to purchase necessary hardware equipment for networking.
   • Unauthorized users can access important data of an organization if centralized data repository is not secured properly by the LAN administrator
   • the transfer speed is faster with a ethernet cable than if you used a wifi box

10. The LAN administrator has the rights to check personal data files of each and every LAN user. Moreover he can check the internet history and computer use history of the LAN users

    • A WPAN (wireless personal area network) is a personal area network - a network for interconnecting devices centered around an individual person's workspace - in which the connections are wireless. Typically, a wireless personal area network uses some technology that permits communication within about 10 meters - in other words, a very short range. One such technology is Bluetooth, which was used as the basis for a new standard, IEEE 802.15
    • ADVANTAGES
      • Low power consumption Low cost Small personal networks Communication of devices within a personal space
