らないという不便さがあった。For example, a personal computer system that can process Japanese data but only has a small-capacity external storage device (for example, a floppy disk), and a small computer system that is equipped with an external storage device such as a large-capacity disk but does not have Japanese processing functions. If you have a computer system and try to receive large amounts of data from a Japanese database via a public telephone line etc. and a modem, the conventional connection method will only allow you to connect to one of the systems. Therefore, this large amount of data cannot be loaded into the system, or even if it is loaded, it must be stored in pieces, for example, on a number of floppy disks, which is inconvenient.
