 Electronics (from Greek Electronics - electron) - the science of interaction electrons with electromagnetic fields and about methods of creation electronic devices and devices in which this interaction is used for conversion electromagnetic energy, mainly for transmission, processing and storage information.

   Also electronics Is an industry physics and techniques in which electronic processes related to the formation and control of free movement are studied electrons and / or others charged particles in various media (vacuum, solid body gas, plasma) and at their borders, as well as problems and methods of development electronic devices for various purposes.

The most characteristic types of such transformations  -  generation,  strengthening  and  reception  electromagnetic oscillations  with  frequency  up to 1012Hz as well  infrared,  visible,  ultraviolet  and  x-ray radiation  (1012—1020  Hz). Conversion to such high frequencies is possible due to extremely low inertia  electron  - the smallest of the currently known charged particles. Interactions are studied in electronics  electrons  as with macrofields in the workspace  electronic device and with microfields inside  atom,  molecules  or  crystal lattice.

  Electronics is based on many sections  physics  -  electrodynamics,  classical  and  quantum mechanics,  solid state physics, optics,  thermodynamics, as well as on  chemistry,  metallurgy,  crystallography  other  science. Using the results of these and a number of other industries  knowledge, on the one hand, poses new challenges to other sciences, which stimulates their further development, on the other  - creates new ones  electronic devices  and devices and thus arms  science  qualitatively new means and  research methods. Practical tasks of electronics: development  electronic devices  and devices that perform different  functions  in conversion systems and  information transfer, c  control systems, c  computer technology, as well as in energy  devices; development of scientific bases  technology  production  electronic devices  and  technology that uses electronic and ionic processes and devices for various industries  science  and  techniques.

Electronics play a leading role in  scientific and technological revolution. Implementation  electronic devices  in various fields  human activity  to a large extent (often decisive) contributes to the successful development of complex scientific and technical problems, increase  productivity  physical and mental  labor, improvement  economic indicators  production. Based on the achievements of electronics is evolving  manufacturing industry  electronic equipment  for different  types of communication,  automation, television,  radar,  computer technology,  process control systems,  instrument making, as well as equipment  lighting,  infrared technology,  radiology  and others.
