A communication system including: a terminal ( 121 ); and a device ( 111 ), a device ( 112 ), and a device ( 113 ) existing within a LAN ( 110 ) connected to the terminal ( 121 ) through the Internet. The terminal ( 121 ) includes: a representative device preference storing unit ( 14 ) that stores information about processing performed by plural devices; a terminal control unit ( 15 ) that determines a representative device serving as a representative from among a plural devices based on information stored in the representative device preference storing unit ( 14 ); and a terminal side communication unit ( 10 ) that transmits a request for information about the devices within the LAN ( 110 ) to the representative device and receives a response to the request from the representative device. The device ( 111 ) includes: a device side communication unit ( 1 ) that receives a request for the information about the devices within the LAN from the terminal ( 121 ); and a device control unit ( 6 ) that acquires the information about the devices within the LAN ( 110 ) from the devices within the LAN ( 110 ). When receiving the request from the terminal ( 121 ), the device side communication unit ( 1 ) further transmits, as a response, the information acquired by the device control unit ( 6 ) to the terminal ( 121 ).
