Introduction to Electronics Communication essays Introduction to Electronics Communications The field of electronics can be roughly divided into three major subfields, computers, communications and control. Virtually every electronic application can be classified as part of one of these three divisions. The largest field in terms of the sales of equipment and services and the number of employees in the computer field. It is also the youngest of the three. The communications industry is the second largest in size and is most certainly the oldest since electronics really started with radio communications. The smallest field is controlled. The computer industry is concerned with the development and servicing of computer hardware and software used by business, industry, and government for the processing, storage, and retrieval of data. The communications industry is concerned with electronic equipment used for the transfer of information between two or more points. That information may be voice, television pictures, computer data, or some other form of electronic information. The control filed is concerned with electronic power as well as various kinds of electronic components and circuits used to operate lights, heating elements, electric motors, and other devices. Although computers, communications, and control are three distinct fields, many applications involve the use of two or even all three disciplines. For example, computers are widely combined with control systems to automate factories and plants. Many computers are also part of networks that allow them to exchange data. In addition, the technologies from communications and control are often combined to perform remote operations. Communication is the basic process of exchanging information. It is what humans do to convey their thoughts, ideas, and feelings to one another. Humans have been communicating with one another from the beginning of humankind. Most humans communicated through the spoken ...
