What Is Telecommunications?

Telecommunications has been defined as a technology concerned with communicating from a distance, and we can categorize it in various ways. Figure shows one possible view of the different sections of telecommunications. It includes mechanical communication and electrical communication because telecommunications has evolved from a mechanical to an electrical form using increasingly more sophisticated electrical systems. This is why many authorities such as the national post, telegraph, and telephone (PTT) companies are involved in telecommunications using both forms. Our main concern here is electrical and bidirectional communication, as shown in the upper part of Figure. The share of mechanical telecommunications such as conventional mail and press is expected to decrease, whereas electrical, especially bidirectional, communication will increase and take the major share of telecommunications in the future. Hence, major press corporations are interested in electrical telecommunications as a business opportunity.
