Claim:
A communication apparatus which is connected to an information processing apparatus so as to operate dependent on the information processing apparatus and connects the information processing apparatus and an external apparatus so as to allow communication therebetween, comprising: a judgment unit which acquires and analyzes instruction information transmitted from the external apparatus to the information processing apparatus, judges whether the instruction information is an instruction for directing the information processing apparatus to execute a predetermined operation, and transmits the instruction information to the information processing apparatus if the instruction information is an instruction for directing the predetermined operation; a storage unit which stores the instruction information if the judgment unit judges that the instruction information is an instruction not for directing the predetermined operation; a transmission unit which detects whether the information processing apparatus is in a normal state in which power is consumed normally or a power-saving state in which power consumption is reduced, and transmits the instruction information stored by the storage unit to the information processing apparatus when the information processing apparatus is in the normal state; and a switching unit which switches the communication apparatus to a normal state in which power is consumed normally if the judgment unit judges that the instruction information is an instruction for directing the predetermined operation when the communication apparatus is in a power-saving state in which power consumption is reduced; wherein the power-saving state is a state in which a speed of processing a task is reduced.
