as MRI, CAT and the X-ray machines all rely on electronics in order to work quickly and accurately. The effects of electronics on the contemporary society are very significant. Modern life is difficult to visualize without mobile phones, broadband internet, SIM, digital cameras, home appliances, I-pod, LCD TVs, cell phones, I-phone and lot more. Background Electronics engineering, also referred to as electronic engineering is an engineering discipline which uses the scientific knowledge of the behavior and effects of electrons to develop components, devices, systems, or equipment (as in electron tubes, transistors, integrated circuits, and printed circuit boards) that uses electricity as part of its driving force. Both terms denote a broad engineering field that encompasses many subfields including those that deal with power, instrumentation engineering, telecommunications, semiconductor circuit design and many others. Electronic engineering as a profession sprang from technological improvements in the telegraph industry in th the late 19 century and the radio and the telephone th industries in the early 20 century. People were attracted to radio by the technical fascination it inspired, first in receiving and then in transmitting. Many who went into broadcasting in the 1920s were only 'amateurs' in the period before World War I. The modern discipline of electronic engineering was to a large extent born out of telephone, radio, and television equipment development and the large amount of electronic systems development during World War II of radar, sonar, and communication systems. Electronics in the early 20th century started thriving at a greater speed. From the beginning, electronics got its special recognition. The radio invented by the Italian genius Marconi and the work of Henry Hertz opened the road to further discoveries and inventions. The invention of the television is another miraculous contribution of electronics for the mankind. It was revolution in both communication technology and also for the world media. Today, the distances between the continents do not seem to be far enough. People can he watch the distant things from their home. The entertainment industry has got a new life. The credit goes to the British engineer John Logie Baird who followed the foot prints of Marconi and tried to send the images in the same way as the speech. After a long experiment he found that a series of static pictures if sent within a small interval of time in between them, seem to be moving. This move was successful after a number of trails. The real electronics of today was actually started after the discovery of the transistor effect. Transistor opened the road for the electronics and there after electronics got its independent identity in electrical engineering. More importantly it opened the road for the computing world. Computers of various types started hitting the market and the research works got a boost. Today, computers and communication have become ubiquitous in everyday life. Emerging fields The effect of electronics is not absent in other branches of sciences. Electronics has made its presence in other disciplines such as medicine, mechanical engineering resulting in derivatives such as medical electronics and mechatronics. The aviation industry, entertainment industry and the manufacturing industries have gained increased productivity through electronics. There are new and emerging fields such as quantum communication, nanotechnology and bioinformatics which will be the leading areas of research in future taking human civilization to greater heights. An application of electronics worth mentioning here is the development of simputer. The simputer is a self-contained, open hardware handheld computer, designed for use in environments where computing devices such as personal computers are deemed inappropriate. Due to the low cost, it was also deemed appropriate to bring computing power to the developing countries. The word "Simputer" is an acronym for "Simple, Inexpensive and Multilingual people's comPUTER". In 2004, simputers were extensively used by the government of Karnataka to automate the process of land records procurement. The simputer has seen deployment by the police force to track traffic offenders and issue traffic tickets. 13
Conclusion Electronics as a technology will continue to present very exciting challenges. In the semiconductor industry, Moore's Law has applied for a very long time, yet there is every scope for us to continue to make things smaller. A new field is emerging in electronics that will be a giant leap in computer and electronics science. It is the field of quantum computing and quantum technology. Quantum computing is area of scientific knowledge aimed at developing computer technology based on the principles of quantum theory. We are bound to see many nanotechnology applications within the electronic industry in the near future. These will undoubtedly increase the quality of life in our society.
