Abstract
In this age of the Internet, it is important to take notice of personal-computer communication, which is better than the Internet for two-way communication. This thesis mainly deals with the following three points:1. It has been said that personal-computer communication has made anonymous communication possible. However, if users want to enjoy all of its advantages, actual anonymity is difficult to maintain. 2. Since users issue information in personal-computer communication with no intent to gain profits, the information tends to be true. 3. Many aspects of personal-computer communication impose overload on users.
