1250412 V. INSTRUCTION DESCRIPTION (1) ~- [Technical Field of the Invention] The present invention relates to a data access system and method, and more particularly, to a computer device that transmits a USB cable through a USB cable Access to each other's data in the data storage area. [Prior Art] With the rapid development of information technology, computers have become one of the most important tools in daily life and work. In the process of using computers, people often need to access data from each other in two months. At present, the only way to provide short-distance communication between two computers is the infrared transmission mode. However, since the desktop computer does not have an infrared transmission interface, the infrared transmission of such short-range communication is only Limited to notebook computers (NOTEBOOK). In addition, due to the limitation of the infrared transmission rate, the infrared transmission interface can generally only perform small transmission processing of text files, etc., but cannot transmit processing types such as video broadcasts. On the other hand, if a computer that does not have an infrared transmission interface needs to transmit data, it must be implemented by means of various memory cards (Mem〇ry Card), which not only adds extra cost, but also the size of the shared data is affected by the memory card. Capacity limit. Therefore, how to make the two computers convenient and fast access to each other's resources is a problem that needs to be solved. SUMMARY OF THE INVENTION In view of the above disadvantages of the prior art, the main object of the present invention is to provide a data access system and method, which only need to connect two by using one transmission line.
