Abstract

PURPOSE:To improve the extendability of system, by transferring changing information from an information source to each sub-host for storage and recording, and processing an information retrieval request from a terminal device at the sub-host at this area locally. CONSTITUTION:A host 110 consists of a central processing unit 111, a file device 112, and a communication controller 113 and connected with an information source 120 through lines. Sub-hosts 100 and 200 respectively consist of central processing units 101 and 201, file devices 102 and 202, and communication controllers 103 and 203 and connected with the host 110 via lines. Terminal devices 1000-1002, 2000-2002 are respectively connected to the sub-hosts 100 and 200 at the installed area via lines.
