PROBLEM TO BE SOLVED: To improve power-saving effect by restoring a power source state only when a packet addressed to this system is received. SOLUTION: In a LAN card 1, it is decided whether or not a received packet is addressed to this computer and only when so, an interruption signal to a CPU 211 is generated to restore the power source state from a low power-source ON state to a normal power-source ON state. Therefore, it can be decided whether the packet is a packet that this computer should process in a standby state without actuating a network driver 311, and consequently while environment wherein packet reception addressed to this computer is always responded to is maintained, sufficient power-saving effect can be obtained. |
