Abstract
In a network system without a server, a network device and a system that can share information in all devices efficiently and surely are provided.CPUs of a plurality of devices connected to a network determine a host device based on device numbers and network strengths of each of the devices. When transmitting share information stored in a memory to the host device, the CPUs of the client devices merge share information transmitted from the other client devices with the share information stored in the memories so as to transmit the merged information to the host device. The CPU of the host device generates share information about all the devices so as to distribute the information to all the client devices. When the share information is changed, the CPU of the host device generates finite difference information with respect to previous share information so as to distribute the information to all the client devices. When the share information is successively changed, the CPU of the host device merges the respective pieces of finite difference information so as to distribute the information to the client devices.
