Electronic device and operating method therefor

A method of the electronic device, comprising:

• a first operation performed based on that the electronic device is not connected to an external display device;
• and
• a second operation performed while an external docking device is connected to a wired local area network (LAN) when the electronic device is inserted into the external docking device using a connector and connected to the external output device through the external docking device,
• wherein the first operation includes displaying a first screen including a plurality of icons representing a plurality of application programs in a first format, and
• the second operation includes,
• rendering a second screen including the plurality of icons in a second format;
• providing data associated with the second screen to the external output device through the connector for the external output device to display the second screen;
• and
• connecting the electronic device to the wired LAN through the connector using a first media access control (MAC) address shared with an external device on the wired LAN.

A non-transitory computer-readable storage medium storing one or more programs for performing the steps of:

• performing a first operation based on that an electronic device is not connected to an external output device;
• and
• performing a second operation while an external docking device is connected to a wired local area network (LAN) when the electronic device is inserted into the external docking device using a connector and connected to the external output device through the docking device,
• wherein the first operation includes displaying a first screen including a plurality of icons representing a plurality of application programs in a first format, and
• the second operation includes,
• rendering a second screen including the plurality of icons in a second format,
• providing data associated with the second screen to the external output device through the connector so that the external output device displays the second screen, and
• connecting the electronic device through the connector to the wired LAN using the first media access control (MAC) address shared with an external device on the wired LAN.
