Telecommunication systems are networks that enable the transmission of information over distances using electronic means. They include various technologies such as telephones, internet, and satellites to facilitate communication between individuals and organizations. These systems convert data into signals that can be sent through cables, radio waves, or optical fibers. These systems consist of several components, including transmitters, receivers, and switching equipment. They work together to ensure that messages, whether voice, text, or video, are delivered accurately and efficiently. Telecommunication systems play a crucial role in modern society, connecting people and businesses across the globe.
