An information processing device includes an input unit configured to input data, a processing unit configured to process the data, an output unit configured to output the data, and an execution unit configured to execute a first process, a second process, and a third process. A function of an application is provided by operating the input unit, the processing unit, and the output unit in conjunction with each other. The first process executes application management software that manages activation and termination of the application. The second process executes basic application software that provides a basic function of the information processing device. The third process executes extended application software that provides an extended function added to the information processing device.
