Telecommunications systems are networks that enable the transmission of information over distances. They include various technologies such as telephones, internet, and satellites that facilitate communication through voice, data, and video. These systems rely on both wired and wireless connections to send and receive signals, allowing people to connect across the globe. The main components of telecommunications systems include transmitters, receivers, and communication channels. Transmitters convert information into signals, while receivers decode these signals back into usable information. Communication channels, such as fiber optics or radio waves, serve as the pathways for these signals, ensuring efficient and reliable communication.
