Effects can be of natural or artificial origin. We can consider physical, biophysical effect of the environment to be natural ones. Effects can be deliberate and indeliberate by its character, destructive, neutral or constructive by its direction. Apparently, physical nature of certain effect is the main classifying feature. The target of such an effect is mainly the organism as a physical body.
Energetic effects can cause violation of normal functions of organs and systems.
The level of violation vary from decreasing adaptive capacity, tissues destruction and even to death. Powerful electromagnetic superhigh-frequency radiation, ionizing rays can be examples of such an effect. As we can imagine a computer can be modified to be such a weapon but at some extent. Because it has all types of energetic effects already built-in. The role of the information in man-machine interaction is extremely great.
