PURPOSE: A demonstration and practice apparatus of an information network system is provided to simulate a developed device using a laboratory computer by a user after learning a basic communication theory. CONSTITUTION: A LAN(Local Area Network) is installed on a network system demonstration practice board(100). A hub(101) is to attached on the network system demonstration practice board. A first serial communication part(210) is able to communicate by connecting a first display module(212) to a first LAN adaptor(211) which is connected to the hub and the LAN. A second serial communication part(220) connects a branch board(222) and a second LAN adaptor connected to the hub and the LAN. A plurality of second display modules(223) is connected to the branch board in order to communicate with the second serial communication part. A USB(Universal Serial Bus) converter(231) is connected to a third display module(232) in order to communicate with a USB communication part(230). A wireless communication part(240) communicates with a wireless operation apparatus(244) through an RFID(Radio Frequency Identification) module(243), a Zigbee module(242), or a wireless LAN module(241) connected to the hub and the LAN. An application device(300) is operated by being connected to the LAN of the board. |
