PROBLEM TO BE SOLVED: To provide a network system capable of controlling a device without installing a device driver in a client.SOLUTION: An application execution server 3 receives an application execution request, generates device control information for controlling a device 5, and transmits it to a device server 4. The device server 4 converts the received device control information into command conversion information, stores it, and transmits information to that effect to the application execution server 3. The application execution server 3 transmits response data corresponding to the application execution request to a client terminal 51. The client terminal 51 transmits a device operation request to the device 5 on the basis of the response data. The device 5 transmits a device command request to the device server 4 on the basis of the request, operates according to command conversion information in its response, and transmits an operation result to the client terminal 51. |
