Abstract

The present invention relates to a data transmission system having a first information processor and a second information processor connected with each other through a network and having touch screen interfaces; and a pointer that wirelessly sends data to and/or receives data from the first information processor and the second information processor, wherein the first information processor transmits address information of previously stored data to the pointer, the data corresponding to a first touch signal input through the touch screen interface, the pointer stores the address information received from the first information processor and transmits the stored address information to the second information processor, if an address requesting signal is received from the second information processor, and the second information processor receives stored data from the first information processor and stores the received data, the stored data corresponds to the address information received from the pointer. Thus, In the present invention, a process to set up an network environment is not required as in the conventional data transmission system using the conventional Windows Explorer, so that a normal user having minimal knowledge of networking can transmit data more easily. Moreover, even if the user doesn'"'"'t know the exact IP address information of the information processor storing data to be transmitted or the directory in which a file is stored, the user can transmit data. Further, only the address information of the stored data to be transmitted is stored in the pointer, so that the address storage of the pointer has a greater storage capacity. Data transmission between information processors placed far from each other is accomplished with ease by using the pointer which is easily carried.
