Abstract: A method and a system for updating data are proposed, for allowing a user at a client's computer device to monitor data condition in a server, wherein the server includes a data-updating module and a data-reading module, and is pre-constructed with a database and a corresponding result table. First, when a data source transmits data to the server, the transmitted data are stored in the database. When a predetermined data-updating time is reached in operation of the server, the data-updating module retrieves the data from the database and stores the retrieved data in the result table. When a predetermined data-reading time is reached in operation of the client's computer device, a data-reading request is submitted to the server, allowing the data-reading module to read the data in the result table according to the request and transmit the read data to the client's computer device for display.

Abstract: A shared input/output network management system is proposed, which allows a group of I/O-unequipped computer units, such as a group of servers, to share one single set of I/O devices, including keyboard, monitor, and pointing device, for the purpose of allowing the user to perform management tasks, such as system updates, file maintenance, and hardware/software testing, on these servers through the single set of I/O devices. The proposed shared input/output network management system is characterized by the use of USB (Universal Serial Bus) communication interface, rather than a keyboard/video/mouse (KVM) switch, for connecting all the servers in the server group to a notebook computer running a server group management program, whereby management tasks can be carried out through the I/O devices of the notebook computer and the server group management program running on the notebook computer.
