A telephone network is a system that allows people to communicate over long distances using telephones. It consists of various components, including telephone lines, switching stations, and cell towers. These elements work together to connect calls, enabling voice communication between individuals. There are two main types of telephone networks: landline networks and mobile networks. Landline networks use physical wires to connect homes and businesses, while mobile networks rely on wireless signals transmitted through the air. Both types of networks have evolved over time, incorporating digital technology to improve call quality and expand services.
