Landline telephones are traditional communication devices that connect calls through physical wires. They typically consist of a handset and a base unit, which is connected to a telephone line. Landlines are known for their reliability and sound quality, making them a popular choice for homes and businesses. Unlike mobile phones, which rely on cellular networks, landline telephones use a direct connection to a telephone exchange. This means that they do not require charging and can work during power outages, as long as the phone line remains intact. Many people still use landlines for their stability and ease of use.
