Introduction to Electronics Communication
Introduction to Electronics CommunicationsThe 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 number of employees is 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 control. 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 poin
But despite these long-distance communication attempts, transmission distances were limited. If anything, there is a glut of information in printed form. Communicating over long distances is another problem. It is what humans do to convey their thoughts, ideas and feelings to one another. For example, computers are widely combined with control systems to automate factories and plants. If the signal could be launched from a hill, mountain, or chain of high towers, distances of several miles could usually be achieved. Many computers are also part of networks that allow them to exchange data. For many years, long-distance communication was limited to the sending of verbal or written messages by human runner, horseback, and ship and later by trains. This language barrier continues today, but it can be overcome as humans learn the languages of others and can serve as interpreters. Body movements and facial expressions were effective communication tools. Although computers, communications, and control are three distinct fields, many applications involve the use of two or even all three disciplines. In 1887, radio was discovered, and it was demonstrated in 1895. 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.
