Telecommunication networks are systems that enable the transmission of information over distances. They connect various devices, such as phones, computers, and satellites, allowing people to communicate through voice, text, and data. These networks can be wired, like fiber optic cables, or wireless, like cellular networks and Wi-Fi. The main components of telecommunication networks include transmitters, receivers, and switching systems. Transmitters send signals, while receivers capture them. Switching systems manage the flow of information, ensuring it reaches the correct destination. Overall, these networks play a crucial role in modern communication and information exchange.
