Abstract: An electronic apparatus includes a storage unit which stores therein a guide program regarding the electronic apparatus, a display unit which displays a three dimensional (3D) view of the electronic apparatus and a tag regarding a hardware component appearing on the 3D view when the guide program is executed, an input unit which receives a user command directing to rotate the 3D view, and a control unit which rotates the 3D view according to the user command, and controls the display unit to display the tag regarding the hardware component appearing on the rotated 3D view.

Abstract: A computer system including a computer main body provided with a hard disk drive (HDD) to retrieve/store data and an HDD driver to drive the hard disk drive to rotate at a predetermined rotational speed, further including a lower noise mode selection part allowing a user to select one between a normal mode and a lower noise mode; and a controller to control the HDD driver to drive the hard disk drive to rotate at a maximum speed when the normal mode is selected and at a minimum speed when the lower noise mode is selected. With this configuration, the present invention provides a computer system and a control method thereof, in which a hard disk drive can be set to a lower noise mode by a user.

Abstract: A wireless Internet accessing system allowing determination and/or access to a web page by entering a telephone number of the web page holder in lieu of entering a URL of the web page. For example, the system can have a receiver receiving information from a cellular phone, a wireless Internet accessing unit wirelessly accessing an Internet, a web page address database storing telephone numbers and web page addresses of the respective telephone numbers, and a network access controller. The controller determines whether the received information has both telephone number signals and an identification key signal distinguished from the telephone number signal, retrieves a web page address corresponding to the telephone number from the web page address database, if determined that the identification key signal is additionally included, and controls the cellular phone to be wirelessly connected to the retrieved web page address through the wireless Internet accessing unit.
