In fact, every action and movement of the users depend on the hardware and software of computers and networks. There are still many interactions between the users and the physical environment. For example, if the efficiency of the netw ork is too slow, users will complain to the system manager and the administrator of networks. Old machines will then be replaced by new workstations or a new repeater or hub will be added to their local networks to improve the speed of transmission. Eventually, users still transform their physical environments in order to fit their need although they may not notice the influence of their behaviors, which is like those of people transforming the real environment by their actions in real world.
People are only concerned with where they can get the data or use some server systems.
The function and user-interface of the cognized environment will be modified and improved by the experiences of users. The improvement o f these server systems are based on the knowledge of human interface and computer technology. People will use more and more powerful and multi-function servers in the future because the knowledge is accumulating. Many kinds of servers are applied in cyber space. The cognized environment will automa tically evolve and be improved by the contribution of their users.
