An information processing apparatus includes a first preservation unit configured to preserve execution request information for information processing; an execution unit configured to execute one or more types of the information processing; an execution control unit configured to have the execution unit being capable of executing one of the types of the information processing execute the information processing of the execution request information preserved by the first preservation unit; and a second preservation unit configured to preserve a stop command of the execution unit. If the execution unit does not execute the information processing, the execution control unit checks the second preservation unit if the second preservation unit preserves the stop command to have the execution unit execute a stop procedure.
