This paper showed the some subjects for the managements of the network systems of Personal Computers, Engineering Work Stations and Main Frame.
The operations and examinations of the presents network systems for agriculture, farmers and the forum groups in the rural community showed some subjects for the improvements of network systems.
Then, the academic network systems in Japan has performed the great network service for the researcher in the universities. But many problems and differences arose in the facilities in the network system especially the network system consists by the multiventures. And in these days, many big host systems changed to Unix Work Station and these network uses. Then, the younger genarations showed much interests in the computer and local network system that they can very easily use and that has much utility, especially with personal computer. And the educational course of the "Fundamental Information Science" for the young
generations in the college has become very popular and essential, with much subject as the lack of instructor and equipment.
Here, this study showed the subjects of the coexistences and the network of these many kinds of computers and many kinds of networks as local and wide area and proposed some improvements for users.
