     DETAILED DESCRIPTION OF THE INVENTION 
       [0048]    Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. 
         [0049]    As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, unless otherwise specified, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the metes and bounds of the claims, or equivalence of such metes and bounds are therefore intended to be embraced by the appended claims. 
         [0050]    Hereinafter, a terminal provided with a networking module according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. 
         [0051]      FIG. 1  is a block diagram showing the configuration of a terminal provided with a networking module according to an embodiment of the present invention and a counter terminal connected to the terminal,  FIG. 2  is a block diagram showing the configuration of power supplier of the networking module according to an embodiment of the present invention, and  FIG. 3  is an illustration showing a screen for setting data sharing with another terminal according to an embodiment of the present invention. 
         [0052]    As shown in  FIG. 1 , the terminal  100  according to an embodiment of the present invention comprises a connection port  10  for connecting with another terminal. Hereinafter, another terminal connected with the terminal  100  according to an embodiment of the present invention will be referred to as ‘a counter terminal  200 ’. 
         [0053]    Here, the terminal  100  is a data processing apparatus such as a desktop computer or a portable computer. And the counter terminal  200  is also one of various data processing apparatuses, or an electronic apparatus including storage devices. 
         [0054]    The connection port  10  is a connecting means supporting a communication protocol allowing the terminal  100  to exchange data with another terminal In particular, the connection port may be an USB (Universal Serial Bus) port broadly used in connection with peripherals. 
         [0055]    In addition, a data cable  300  is inserted into the connection port  10  of the terminal  100 . One end of the data cable  300  is inserted into the connection port  10  of the terminal  100  and the other end of the data cable  300  is inserted into a connection port  15  of the counter terminal  200 , whereby the terminal  100  and the counter terminal  200  is connected physically and electrically. 
         [0056]    This is merely an embodiment of the present invention, and the two terminals may be connected without the data cable  300 , if a wireless communicating module supporting the same kind of communication protocol is installed on each of the terminal  100  and the counter terminal  200 . 
         [0057]    For example, in a case where a wireless communicating module supporting a communication protocol such as infrared data communication, Zigbee, Bluetooth, or UWB (Ultra Wide-Band) specification is installed on each of the two terminals, the terminal  100  and the counter terminal  200  can be connected by wireless networking through several steps such as device recognition and selection. 
         [0058]    In the meantime, the terminal  100  comprises a networking module  20 . The networking module  20  receives and/or transmits data from and/or to the counter terminal  200  connected to the terminal  100  through the data cable  300 . 
         [0059]    The networking module  20  exchanges data stored in a storage device (including local disk and removable disk) provided in the terminal  100 , or stored in a storage area such as a folder or a file of the terminal  100  with data stored in a storage device provided in the counter terminal  200  or in a storage area of the counter terminal  200 , according to user settings or commands. 
         [0060]    To perform this, the networking module  20  comprises a controller  20   a  and a storage unit  20   b.  The controller  20   a  is a control means to receive and/or transmit data inputting and/or outputting between the terminal  100  and the counter terminal  200  through the data cable  300 . 
         [0061]    Here, the storage unit  20   b  is a nonvolatile memory means such as a flash memory, ROM (Read Only Memory), M-RAM (Magnetic Random Access Memory), P-RAM (Phase-change Random Access Memory), and Fe-RAM (Ferroelectric Random Access Memory). The storage unit  20   b  stores a device driver which is a program routine by which each operating system of the terminal  100  and the counter terminal  200  recognizes the networking module  20  as a device and communicates with the networking module  20 . 
         [0062]    In addition, the controller  20   a  installs the device driver stored in the storage unit  20   b  on both the terminal  100  and the counter terminal  200 , if a connection of the data cable  300  connected with the counter terminal  200  into the connection port  10  of the terminal  100  is detected. 
         [0063]    Moreover, the storage unit  20   b  may store an interfacing program as an application program which allows the terminal  100  and the counter terminal to exchange data with each other through the networking module  20 . 
         [0064]    Also, the controller  20   a  may install the interfacing program on the two terminals after a connection between the two terminals is detected and the device driver is installed on the two terminals. 
         [0065]    On this occasion, the controller  20   a  may skip installations of the device driver and/or the interfacing program if the device driver and/or the interfacing program are already installed. 
         [0066]    In addition, the controller  20   a  installs the device driver and/or the interfacing program automatically or on command of users. 
         [0067]    After installation of the device driver and the interfacing program, the terminal  100  and the counter terminal  200  runs the interfacing program. The interfacing program is also run automatically or on command of users. 
         [0068]    The interfacing program is run by a control unit  30  of the terminal  100 . The control unit  30  is a control means executing the operating system of the terminal  100 . The control unit  30  may be a central processing unit of the terminal  100 . 
         [0069]    The control unit  30  accesses to the storage unit  20   b  or loads the interfacing program stored in the storage unit  20   b  to a RAM  60  and runs the interfacing program. Then, the control unit  30  executes receiving and transmitting data with the counter terminal  200  through the controller  20   a.    
         [0070]    Meanwhile, in the counter terminal  200 , a control unit  25  of the counter terminal  200  runs the interfacing program. The control unit  25  stores the interfacing program in a HDD (Hard disk drive)  35 , or a RAM (Random Access Memory)  55  and runs the interfacing program. 
         [0071]    Here, the interfacing program is run on the operating systems of the terminal  100  and the counter terminal  200 , and at this time, the device driver is used. 
         [0072]    The interfacing program provides a user interface for selecting storage devices, storage areas, data transmitting directions, or data transmitting policies (or data-synchronization policies) in order to move data between the terminal  100  and the counter terminal  200 . 
         [0073]    That is, the terminal  100  may comprise a plurality of storage devices, for example the HDD  40  and an ODD (optical disk drive)  50 , as shown in  FIG. 1 . 
         [0074]    Meanwhile, the counter terminal  200  may also comprise a plurality of storage devices, for example the HDD  35  and an ODD  45 , as shown in  FIG. 1 . 
         [0075]    The interfacing program may provide lists of storage devices or storage areas of one of the terminal  100  and the counter terminal  200  to the other. 
         [0076]    As above, users can select one of storage devices, storage areas such as folders or files, which users desire to transmit, in the user interface provided by the interfacing program. 
         [0077]    The interfacing program recognizes a plurality of the storage devices of the terminal  100  and the counter terminal  200 , and provides lists of them to the terminal  100  and the counter terminal  200 . Then users can select a storage device or a storage area which stores data to be transmitted, and a storage device of a storage area which is to store the data transmitted. 
         [0078]    For example, if a user selects the HDD  40  of the terminal  100  and the HDD  35  of the counter terminal  200  through the interfacing program, the networking module  20  receives and transmits the data selected from data stored in the two HDD  35  and  40 . 
         [0079]    If a user commands to synchronize the ODD  50  of the terminal  100  with a certain folder in the HDD  35  of the counter terminal  200 , data in the ODD  50  and data in the folder of the HDD  35  are synchronized. 
         [0080]    In the above, the transmitting direction or the synchronization direction may be selected by users through the interfacing program. 
         [0081]    That is, users can select a certain data through the interfacing program, and transmit the data between the two terminals  100  and  200  by a selected direction. Here, users can input commands and selections through one of the terminal  100  and the counter terminal  200 . 
         [0082]    Also, data stored in the terminal  100  can be transmit to the counter terminal  200 , and data stored in the counter terminal  200  can be transmit to the terminal  100 . 
         [0083]    Furthermore, data stored in a storage device or a storage area of the terminal  100  and data stored in a storage device or a storage area of the counter terminal  200  can be synchronized. 
         [0084]    That is, if a user commands synchronization between the HDD  40  of the terminal  100  and the HDD  35  of the counter terminal  200  on the user interface provided by the interfacing program, data stored in the HDD  40  of the terminal  100  and data stored in the HDD  35  of the counter terminal  200  become synchronized to each other. 
         [0085]    On this occasion, users can select synchronization direction. That is, data of the HDD  35  of the counter terminal  200  is replaced with the data stored in the HDD  40  of the terminal  100  or data of the HDD  40  of the terminal  100  is replaced with the data stored in the HDD  35  of the counter terminal  200 . 
         [0086]    Also, data stored in the HDD  35  of the counter terminal  200  but not stored in the HDD  40  of the terminal  100  may be moved to the HDD  40  of the terminal  100 . Likewise, data stored in the HDD  40  of the counter terminal  100  but not stored in the HDD  35  of the terminal  200  may be moved to the HDD  35  of the terminal  200 . 
         [0087]    In addition, as described above, users can select storage devices or storage areas for data-synchronization through the user interface provided by the interfacing program. 
         [0088]    That is, users may select a folder from each of the two terminals  100  and  200 , and synchronize the selected two folders. 
         [0089]    In detail, first of all, storage devices and storage areas of the terminal  100  are displayed in the terminal  100  in order for users to select storage devices and storage areas to be permitted to share. Then users may select at least one storage device or area in which data is permitted to share. 
         [0090]    After then, a list of the selected storage devices or areas is displayed on the counter terminal  200 . 
         [0091]    Likewise, in the counter terminal  200 , storage devices and storage areas of the counter terminal  200  are displayed in the terminal  200  in order for users to select storage devices and storage areas permitted to be shared. Then users may select at least one storage device or area in which data is permitted to be shared. 
         [0092]    A list of the selected storage devices or areas of the counter terminal  200  is displayed on the terminal  100 . 
         [0093]    Here, the interfacing program allows users to set a receiving and transmitting level on each of the storage devices and areas selected to be shared. 
         [0094]    That is, in a case where a user selects a certain folder of the terminal  100  and permits to share data in the selected folder with the counter terminal  200 , it may be selected whether the data in the folder can be only read or can be both read and edited through the counter terminal  200 . 
         [0095]    Likewise, in a case where data stored in the ODD  45  of the counter terminal  200  is permitted to be shared with the terminal  100 , users can set the data in the ODD  45  to be able to only be displayed on the terminal  100 . 
         [0096]    In this case, in permitting to transmit data in the terminal  100  or the counter terminal  200 , a process to certify an authority to allow data transmitting may be done. 
         [0097]    For example, the interfacing program requires users to input a password in the process to allowing data receiving or transmitting. And only when a password inputted corresponds to a predetermined password, data is transmitted. 
         [0098]    Meanwhile, on the list of the storage devices and areas of the counter terminal  200 , permitted to be share data with the terminal  100 , wherein the list is displayed on the terminal  100 , users can select at least one of the storage devices and areas to which data stored in the terminal  100  is transmitted, or from which data transmitted to the terminal  100 . 
         [0099]    For example, if it is tried to transmit data stored in the terminal  100  to a folder of the counter terminal  200 , a name or an icon of a file or a folder to be transmitted is selected and dragged-and-dropt to one of names or icons representing storage devices or areas of the counter terminal  200  in the terminal  100 , whereby the file or the folder is transmitted to a storage device or area of the counter terminal  200 . 
         [0100]    Furthermore, if a user selects data to be transmitted to the counter terminal  200  in the terminal  100  and commends to transmit, the interfacing program provides user interface for selecting one of storage devices or areas of the counter terminal  200  permitted to be shared, to the terminal  100  and then a user selects one of storage devices or areas so that the data selected to be transmitted is transmitted to the one of storage devices or areas of the counter terminal  200 . 
         [0101]    Likewise, if a user selects data to be transmitted to the terminal  100  in the counter terminal  200  and commends to transmit, the interfacing program provides user interface for selecting one of storage devices or areas of the terminal  00  permitted to be shared, to the counter terminal  200  and then a user selects one of storage devices or areas so that the data selected to be transmitted is transmitted to the one of storage devices or areas of the terminal  100 . 
         [0102]    Also, in the terminal  100  or the counter terminal  200 , users can choose a storage device or area of the terminal  100  and a storage device or area of the counter terminal  200 , and then command to synchronize data of the two selected storage devices or areas. 
         [0103]    For the purpose of making it easier to select storage devices or areas and to transmit or synchronize data, the terminal  100  and the counter terminal  200  may access to storage areas of each other through Window explorer (or window browser) on the operation system based on Window of Microsoft and read or write data of the storage areas. 
         [0104]    To transmit or synchronize data, each of control units  30  and  25  of the terminal  100  and the counter terminal  200  runs the interfacing program and then the control unit  30  of the terminal  100  allows the controller  20   a  of the networking module  20  to input and/or output data. After then, the controller  20   a  moves data through the data cable  300 . 
         [0105]    The interfacing program displays the progress and the completion of data transmission through each display unit of each of the two terminals  100  and  200  while moving data between the two terminals. 
         [0106]    Then, if the terminal  100  and the counter terminal  200  are disconnected from each other, the interfacing program run by the counter terminal  200  may uninstall itself and the device driver. 
         [0107]    That is, if the data cable  300  is disconnected from the connection port  10  or  15 , the control unit  25  of the counter terminal  200  detects this and then uninstalls the interfacing program and the device driver. 
         [0108]    Here, the uninstallation is performed by an uninstall program included in the interfacing program. 
         [0109]    However, in a case where the terminal  100  and the counter terminal  200  are connected to each other by wireless way, the communication between the terminal  100  and the counter terminal  200  is disconnected by a disconnecting condition such as a user command, the passage of time and the completion of data transmission and the terminal  100  and the counter terminal  200  detect this. 
         [0110]    In addition, if the counter terminal  200  is also a terminal provided with a networking module, such as the terminal  100  according to the present invention, the uninstallation process may be skipped. 
         [0111]    Further, the interfacing program and the device driver for the networking module may be uninstalled also in the terminal  100 , wherein the interfacing program and the device driver are uninstalled only on the RAM  60  and the HDD  40 , not on the storage unit  20   b  of the networking module. 
         [0112]    In the meantime, the terminal  100  according to an embodiment of the present invention is connected to Internet through an Internet module  65  of the counter terminal  200 . 
         [0113]    A function to change the Internet sharing environment of the terminal  100  and the counter terminal  200  is provided by a program included in the interfacing program or another program. 
         [0114]    That is, the interfacing program or the another program is automatically installed and run on the terminal  100  and the counter terminal  200  when connection between the terminal  100  and the counter terminal  200  is detected and changes the Internet sharing environment. 
         [0115]    The values changed will be described in detail later on with reference to  FIG. 6 . 
         [0116]    If values of the Internet sharing environment are changed, the terminal  100  can be connected to the Internet through the Internet module  65  of the counter terminal  200 . 
         [0117]    Meanwhile, each control unit  30  or  25  of the terminal  100  and the counter terminal  200  blocks the terminal  100  or the counter terminal  200  to enter a power saving mode through the operating system when connection between the terminal  100  and the counter terminal  200  is detected. 
         [0118]    Since power must be supplied to storage devices such as the HDDs  40  and  35  and the ODDs  50  and  45  in order to transmit data between the terminal  100  and the counter terminal  200 , the terminal  100  and the counter terminal  200  are prevented from entering the power saving mode while transmitting data. 
         [0119]    If the terminal  100  and the counter terminal  200  are in the power saving mode when the terminal  100  and the counter terminal  200  are connected to each other, the terminal  100  and the counter terminal  200  are resumed from the power saving mode. 
         [0120]    In another embodiment of the present invention, the terminal  100  and the counter terminal can share hardwares of each other, if the terminal  100  and the counter terminal  200  are connected to each other. 
         [0121]    This may be achieved by transmitting data to be input/output to/from hardwares through the networking module provided in the terminal  100 . 
         [0122]    For example, if one of input devices of the terminal  100 , such as a mouse, a keyboard or a touch-pad, is permitted to be shared with the counter terminal  200 , signals input by the one of the input devices are transmitted to the counter terminal  200  through the networking module, so that the one of the input devices of the terminal  100  may be used as an input device for the counter terminal  200 . 
         [0123]    In this case, the signals input by one of the input devices may be transmitted to both of the control units  30  and  25  of the two terminals  100  and  200 , and processed by the both of the control units  30  and  25 . 
         [0124]    But if one of input devices of the terminal  100  is permitted to be used as an input device only for the counter terminal  200 , signals input by the one of the input devices may be transmitted only to the counter terminal  200 . 
         [0125]    Here, users may select whether to permit sharing one of the input devices of the terminal  100  with the counter terminal  200  on the user interface provided by the interfacing program or on a user interface basically provided by the operating system of the terminal  100 . 
         [0126]    In addition, in a case where one of the input devices of  100  is permitted to be shared with  200 , as above, a user interface to stop sharing the one of the input devices may be provided in the counter terminal  200 . 
         [0127]    The user interface to stop sharing the input device may be provided by the interfacing program or by the operating system of the counter terminal  200 . 
         [0128]    If an input device of the terminal  100  is permitted to be shared with the counter terminal  200 , the control unit  25  of the counter terminal  200  detects this and provides the interface to stop sharing. When a user commands to stop sharing through the interface to stop sharing the input device, signals input by the input device are no longer transmitted to the counter terminal  200 . Then, the signals input by the input device are processed in the terminal  100 . 
         [0129]    These can be applicable in a case of permitting an input device of the counter terminal  200  to be shared with the terminal  100 . 
         [0130]    As described above, in a case where an input device of one of the two terminals  100  and  200  is permitted to be shared with the other, signals from the input device may be transmitted to the other through the networking module  20 , so that the two terminals  100  and  200  can share their input devices. 
         [0131]    As another example, if an output device such as a monitor or a speaker of the counter terminal  200  is permitted to be shared with the terminal  100 , signals to be output by the output device are transmitted from the terminal  100  to the counter terminal  200  through the networking module  20 , so that the output device of the counter terminal  200  may be used as an output device for the terminal  100 . 
         [0132]    Here, the same signals can be output by both the terminal  100  and the counter terminal  200 . To allow an output device of the counter terminal  200  to be shared with the terminal  100 , the interfacing program being run on the counter terminal  200  may provide a user interface by which users can select whether to permit an output device to be shared. 
         [0133]    Also, the operating system of the counter terminal  200  may provide a user interface providing the same function. 
         [0134]    For example, as shown in  FIG. 3 , in the device manager basically provided in the operating system to set hardware variables, a shortcut menu shown up when a monitor icon is right-clicked includes a sharing item, and a monitor corresponding to the monitor icon may be shared with another terminal by clicking on the sharing item. 
         [0135]    Furthermore, as described above, if an output device of the counter terminal  200  is permitted to be shared with the terminal  100 , a user interface to stop sharing the output device is provided in the terminal  100 . 
         [0136]    The user interface to stop sharing the output device is provided by the interfacing program being run on the terminal  100  or by the operating system of the terminal  100 . 
         [0137]    When the output device is stopped from being shared, signals generated by the counter terminal  200  are displayed on the output device. 
         [0138]    In the meantime, a power supplier of the networking module of the terminal  100  according to an embodiment of the present invention, as shown in  FIG. 1  includes a switch S connected across a power line through which internal power (voltage V 1 ) is provided to the terminal  100 . 
         [0139]    The internal power (voltage V 1 ) source may be a battery or a regulator or an adapter converting external AC power to DC power according to a kind of the terminal and to power supplying states. 
         [0140]    The switch may be a circuit element or device being able to control electric current based on control signals, such as a BJT (Bipolar Junction Transistor) or a FET (Field Effect Transistor). 
         [0141]    The internal power (voltage V 1 ) is supplied to every element of the terminal  100  and also to the networking module  20 . However, in a state where the terminal  100  is not connected to another terminal, such as the counter terminal  200 , the switch S is opened, so that the internal power may be not supplied to the networking module  20  in order to reduce power consumption. 
         [0142]    If a control signal is applied on the switch S, in other words, if an external power (voltage V 2 ) is supplied to the switch S from the counter terminal  200  through the data cable  300 , the switch S is shorted, so that the internal power (voltage V 1 ) is supplied to the networking module  20 . Accordingly, the networking module  20  is activated, and then data transmission can be done. 
         [0143]    Meanwhile, the external power (voltage V 2 ) is applied on some pins of a chip included in the controller  20   a,  so that the controller  20   a  may detect whether the external power is input to the terminal  100 . 
         [0144]    After then, the counter terminal  200  is connected to the terminal  100  and the internal power is provided to the networking module  20 . Thus the controller  20   a  detects the external power (voltage V 2 ) and then installs the interfacing program and the device driver as described above. 
         [0145]    Moreover, the control unit  30  of the terminal  100  may detects the external power supplied from the counter terminal  200  through the data cable  300 , and the control unit  25  of the counter terminal  200  may detects power supplied from the terminal  100  through the data cable  300 , so that both of the control units  30  and  25  can detect connection and disconnection of each other. 
         [0146]    In this case, each control unit  30  or  25  of the two terminals  100  and  200  runs the uninstall program included in the interfacing program so that the interfacing program and the device driver may be uninstalled, if the data cable  300  is disconnected. 
         [0147]    Whereas, even if the disconnection between the terminal  100  and the counter terminal  200  is detected, the control unit  30  of the terminal  100  may not run uninstall program not to uninstall the interfacing program and the device driver, in order to prevent the terminal  100  from repetitively re-installing the interfacing program and the device driver. In addition, if the counter terminal  200  is a terminal provided with the networking module  20  according to an embodiment of the present invention, such as the terminal  100 , the control unit  25  of the counter terminal  200  may also not run the uninstall program. 
         [0148]    Hereinafter, a method for receiving and transmitting data according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. 
         [0149]      FIG. 4  is a flow chart showing a process of receiving and transmitting data between two terminals according to an embodiment of the present invention,  FIG. 5  is a flow chart showing a process of receiving and transmitting data between two terminals according to another embodiment of the present invention, and  FIG. 6  is a flow chart showing a process of receiving and transmitting data between two terminals according to another embodiment of the present invention. 
         [0150]    As shown in  FIG. 4 , the method for receiving and transmitting data according to an embodiment of the present invention starts with a step of connecting the terminal  100  and the data cable  300  connected to another terminal (hereinafter, a counter terminal  200 ) (S 100 ). 
         [0151]    In the step  100  (S 100 ), the control unit  30  of the terminal  100  and the controller  20   a  of the networking module  20  detect power provided through the data cable  300 . 
         [0152]    Here, if each of the terminal  100  and the counter terminal  200  includes a wireless communicating module supporting the same wireless communication protocol, the step  100  may comprise a step of activating each of the wireless communicating module of the terminal  100  and the counter terminal  200  and a step of connecting the each wireless communicating module to a wireless network. Moreover, the step  100  may comprise a step in which the terminal  100  recognizes the counter terminal  200  connected to the terminal  100  through the wireless network, and a step certifying an authority to connect the terminal  100  to another terminal 
         [0153]    Then, the switch S connected across the power line through which the internal power is supplied to the networking module  20  is turned on by the external power (voltage V 2 ) supplied from the counter terminal  200  through the data cable  300 , thus the internal power in supplied to the networking module  20  (S 110 ). 
         [0154]    The networking module  20 , however, is not necessarily activated by the above way. The terminal  100  may supply just standby power to the networking module  20  usually, and supply driving power to the networking module  20  when connection with another terminal is being detected. 
         [0155]    In the step  110  (S 110 ), if the networking module  20  is activated, the controller  20   a  provided in the networking module  20  installs the interfacing program and the device driver stored in the storage unit  20   b  on the terminal  100  and the counter terminal  200  (S 120 ). 
         [0156]    At this time, the controller  20   a  may install the interfacing program and the device driver automatically or on user command. In addition, the step  120  (S 120 ) may include a step of asking whether to install the interfacing program and the device driver. 
         [0157]    Here, if the interfacing program and the device driver have already installed in the terminal  100  and the counter terminal  200 , the step  120  can be skipped. 
         [0158]    Then, if the installation of the interfacing program and the device driver is completed in the step  120 , the control units  30  and  25  of the terminal  100  and the counter terminal  200  run the interfacing program using the operating system (S 130 ). Also, users can command to run the interfacing program. 
         [0159]    The interfacing program run in the step  130  (S 130 ) may provide a user interface in order to make it easier to transmit data. The user interface provided by the interfacing program allows users to select storage areas of the terminal  100 , storage areas of the counter terminal  200 , data-transmitting directions and data-transmitting policies regarding data to be transmitted (S 140 ). 
         [0160]    In the user interface, a list of storage devices and areas of the terminal  100  is provided, so that users can select one of the storage devices and areas on the list. In addition, in the user interface provided in the counter terminal  200 , a list of storage devices and areas of the counter terminal  200  is provided, so that users can choose one of the storage devices and areas on the list. 
         [0161]    Here, the selected storage devices and areas of one of the two terminals  100  and  200  are permitted to be shared with the other. A list of the selected storage devices and areas of the terminal  100  is displayed on the counter terminal  200 , and a list of the selected storage devices and areas of the counter terminal  200  is displayed on the terminal  100 . 
         [0162]    Accordingly, users may select on the terminal  100  a storage device or area of the counter terminal  200  in which data desired to be transferred to the terminal  100  is stored, and then select on the terminal  100  a storage device or area of the terminal  100  in which data transmitted from the counter terminal  200  is to be stored. Then users may input a data transmission, exchange or synchronization command. 
         [0163]    According to the input command, data desired to be transferred is transferred from the counter terminal  200  to the terminal  100  (S 150 ). 
         [0164]    Likewise, if users want data to be transmitted from the terminal  100  to the counter terminal  200 , users may select on the counter terminal  200  a storage device or area of the terminal  100  in which data desired to be transferred to the counter terminal  200  is stored, and then input a data transmission command. 
         [0165]    Accordingly, the data desired to be transferred to the counter terminal  200  is transferred (S 150 ). 
         [0166]    In the step  140  (S 140 ), the data transmitting direction which may be selected on the user interface provided by the interfacing program represents whether to transmit data from the terminal  100  to the counter terminal  200  or from the counter terminal  200  to the terminal  100 . 
         [0167]    The data transmitting policy represents whether to transmit data selected to be transmitted, or synchronize two storage areas of the terminal  100  and the counter terminal  200 . If data in a storage area of the terminal  100  and data in a storage area of the counter terminal  200  is synchronized, the transmitting policy comprises on which one of the two storage areas the synchronization bases. 
         [0168]    In the step  150  (S 150 ), the control unit  30  of the terminal  100  and the control unit of the counter terminal  200  communicates through the networking module  20 , and the networking module  20  controls input/output of data between the terminal  100  and the counter terminal  200 . 
         [0169]    In the meantime, as shown in  FIG. 5 , a method for receiving and transmitting data according to another embodiment of the present invention starts with detecting disconnection between the terminal and the data cable  300  connected with another terminal, for example the counter terminal  200  (S 200 ). 
         [0170]    The step  200  (S 200 ) is conducted by detecting physical disconnection between the connection port  10  and the data cable  300  or discontinuance of power supply through the data cable  300 . 
         [0171]    In a case where the terminal  100  and the counter terminal  200  are connected by wireless way, the step  200  is conducted by detecting disconnection of wireless communication. Then, if the disconnection between the terminal  100  and the counter terminal  200  is detected, each of the control units  30  and  25  quits the interfacing program (S 210 ). 
         [0172]    After then, the interfacing program and the device driver installed on the counter terminal  200  are uninstalled (S 220 ). 
         [0173]    The step  220  (S 220 ) is conducted by the uninstall program which is automatically run at the same time with detecting disconnection. 
         [0174]    Likewise, the interfacing program and the device driver installed on the terminal  100  may be also uninstalled. But if the counter terminal  200  also has the networking module  20 , the interfacing program and the device driver installed on the counter terminal  200  may not be uninstalled. 
         [0175]    Meanwhile, as shown in  FIG. 6 , a method for receiving and transmitting data according to another embodiment of the present invention provides a way how the terminal  100  is connected to Internet through the Internet module  65  of the counter terminal  200 , in a case where the terminal  100  can&#39;t be connected to Internet, but the counter terminal can. 
         [0176]    The method stats with connecting the terminal  100  and the counter terminal  200  through the data cable  300  (S 300 ). 
         [0177]    In the step  300  (S 300 ), if connection between the terminal  100  and the counter terminal  200 , the networking module is activated (S 310 ). 
         [0178]    The connection between the terminal  100  and the counter terminal  200  may be detected in various ways, for example as described above, by detecting power supply from the data cable  300 . 
         [0179]    The activation of the networking module  20  means that the networking module  20  starts to be supplied with driving power, in a state where being supplied only with standby power or where being off 
         [0180]    After the networking module  20  is activated in the step  310  (S 310 ), the controller  20   a  installs the interfacing program and the device driver stored in the storage unit  20   b  on the terminal  100  and the counter terminal  200  (S 320 ). Here, if the interfacing program and the device driver are already installed, the step  320  (S 320 ) may be skipped. 
         [0181]    The controller  20   a  of the networking module may set Internet sharing environment of the terminal  100  and the counter terminal  200  (S 330 ). 
         [0182]    In the operating system based on Window of Microsoft, Internet sharing is supported. The controller  20   a  intermediates communication between the control unit  30  of the terminal  100  and the control unit  25  of the counter terminal  200  by the installed device driver, and permits each of the control unit  30  or  25  to change Internet sharing environment of the terminal  100  and the counter terminal  200 . 
         [0183]    A program for changing the Internet sharing environment may be included in the interfacing program or be stored as separate program in the storage unit  20   b.    
         [0184]    In the counter terminal  200 , the step  330  (S 330 ) is conducted by setting the Internet protocol address of the counter terminal  200 , a sub-network mask value and a domain name server address. 
         [0185]    Likewise, in the terminal  100 , the step  330  is conducted by setting the Internet protocol address of the terminal  100 , a sub-network mask value and a gateway address. 
         [0186]    Here, the Internet protocol address, the sub-network mask value and the gateway address are set to predetermined values. 
         [0187]    The Internet protocol address set on the counter terminal  200  and the Internet protocol address set on the terminal  100  are determined to be related to each other. The sub-network mask values set on the terminal  100  and the counter terminal  200  are determined as the same value. The gateway address set on the terminal  100  is predetermined as the Internet protocol address of the counter terminal  200 .
