Abstract: In information processing between computers which perform a remote operation via a network, all or a part of process information being executed by an operation target and data for use in a process are transmitted beforehand to an operation unit, and the operation unit continues the processing by use of the process information transmitted beforehand when connection via the network for communication between the computers is interrupted or cut. When it is detected that the communication returns to a normal state, the process information being executed by the operation unit and the data for use in the process are transmitted to the operation target, and the operation target continues execution of an information processing program by use of the received process information and the data for use in the process.

Abstract: When a user depresses a power button of a client the client transmits a power processing request. A management server which collectively manages power control requests receives the power processing request from the client and processes the power of a server which is allocated to the user in place of the client. Also, the management server generates screen information of the server which is in process of power processing and transmits it to the client. The client displays received screen information on a display device.
