FIELD: physics, communications.SUBSTANCE: invention relates to a communication device and a communication method. The communication device comprises: a first operating system which executes commands belonging to a first group of commands; a second operating system which executes commands belonging to a second group of commands different from the first group of commands; and a determining unit which, when a first command belonging to the first group of commands is obtained from an external device, inputs the first command into the first operating system, when a first response is output from the first operating system as a response to the first command, transmits the first response to the external device and, when a second command belonging to the second group of commands is output from the first operating system as a response to the first command, inputs the second command into the second operating system and further inputs into the first operating system a second response as a response to the second command which is output from the second operating system.EFFECT: performing command fetching between operating systems without lowering operating system security levels.12 cl, 19 dwg |
