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, which work together to connect calls. When someone makes a call, their voice is converted into electrical signals that travel through these components to reach the recipient. 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 technology to connect cell phones. Both types enable voice communication and can also support data services like texting and internet access.
