Telecommunication systems are networks that enable the transmission of information over distances. They use various technologies, such as telephones, internet, and satellites, to facilitate communication between individuals and organizations. These systems can transmit voice, data, and video, allowing for real-time interaction and information sharing. The main components of telecommunication systems include transmitters, receivers, and communication channels. Transmitters convert information into signals, which are then sent through channels like fiber optics or radio waves. Receivers decode these signals back into usable information, making it possible for people to connect and communicate effectively across vast distances.
