A display processing unit displays on a display unit an item acquisition status using the item acquisition information acquired by the item information acquiring unit.

Abstract: In an arrangement wherein a first personal computer and a second personal computer perform peer-to-peer communication, and the first personal computer has an additional function module which the second personal computer does not have, the first personal computer and the second personal computer can perform peer-to-peer communication based on the additional function module. Accordingly, the functions of a function module can be used for communication even in the event that not all terminals communicating have the function module.
