Abstract: A server system, a data transmission system and a data transmission method thereof are disclosed. The data transmission method includes the following steps: dividing a piece of data into a plurality of packets by the server system; transmitting an nth packet to a device end by the server system, wherein n is greater than or equal to 1; transmitting an (n+1)th packet after the nth packet is transmitted by the server system; and receiving an nth acknowledgement generated by the device end based on receiving the nth packet from the server system, wherein it is earlier to transmit the (n+1)th packet than to receive the nth acknowledgement.

Abstract: A data access method of transactional file system and electronic apparatus are provided. The method includes: when performing a data access operation, selecting a valid transaction point as a first transaction point from a transaction point table including a plurality of transaction points; copying the information in the first transaction point to a second transaction point in the plurality of transaction points, and executing the data access operation according to the information in the second transaction point; and when the data access operation is completed, executing a commit instruction and setting the second transaction point as the valid transaction point according to the commit instruction.

Abstract: A computer device includes a power managing controller coupled to a system controller, which in turn is coupled to an optical disk drive via an IDE bus, and operable in a normal mode, where electric power is supplied to the system controller, and a suspend mode, where electric power to the system controller is disrupted. A control key set is coupled to a keyboard controller that is coupled to the system controller and the power managing controller, and that is further coupled to the optical disk drive via a serial bus. The keyboard controller generates a control signal in accordance with operation of the control key set and received directly by the optical disk drive via the serial bus when the power managing controller operates in the suspend mode for controlling operation of the optical disk drive.

Abstract: A method for managing the input codes from the keyboard and the point device and an apparatus thereof are provided. When the computer system is not coupled to a PS/2 mouse and a hybrid keyboard is found to be connected to the computer system, the method first requests the hybrid keyboard to send a leading code designated to the pointing device. Afterwards, the method detects whether an input code from the hybrid keyboard has a leading code. And if there is a leading code, the method emulates the input code as a PS/2 mouse code and sends the emulated PS/2 mouse code to the computer system.
