Abstract
The present invention relates to a data communication apparatus which interfaces with a local area network (LAN), receives data from a transmission side, notifies a receiver on the LAN that the data was received and manages a plurality of data received individually for each notification destination. Notification that the plurality of individually-received data has been received is performed collectively. Thus, communication efficiency and communication traffic are improved even where a number of transmissions to the same destination and a number of receptions to the same destination are performed.
