Disclosed herein are an upgradable electronic device, a server for upgrading the electronic device, and a method for upgrading the electronic device. The electronic device includes: a storage unit storing program data; a communication unit receiving and storing a file for updating the program data from a management server and transmitting update data for updating the program data based on the stored file; and a controller updating the program data in response to the update data, wherein the update data transmitted from the communication unit includes delta data and an instruction, the delta data including only a changed portion of the program data.

Upgradable electronic device, server for upgrdading electronic device, and method for upgrading electronic device

The present invention relates to a network system and a control method thereof. The network system includes: a commercial electric appliance comprising a cost system for an operation thereof; and a control device communicably connected to the commercial electric appliance, wherein the control device comprises a display unit configured to remotely monitor operation information of the commercial electric appliance.

Network system and method for controlling same

A network system is provided. The network system includes: a first component having a first device code and performing a predetermined function; and a second component having a second device code and exchanging information with the first component for communication connection. One of the first and second components receives a command for the communication connection and generates a connection sequence. The component generating the connection sequence exchanges communication addresses and device codes with the other component receiving the connection sequence. If the information has not been exchanged between the first component and the second component during a predetermined time, the first component and the second component are switched to a communication connection standby mode.

Network system

A method for controlling an electronic device is provided. The method may include displaying, on a display, information related to at least one of a plurality of items to be managed or processed by the device, selecting at least one piece of item information displayed on the display, recognizing the selected piece of item information, and storing the recognized piece of item information into a memory as an object to be managed or processed by the device.
