Landline telephones are traditional communication devices that connect calls through physical wires. They typically consist of a handset and a base unit, allowing users to make and receive calls using a telephone network. Landline phones 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. They require a power source, but many models can still function during power outages. Despite the rise of mobile phones and VoIP services, landlines remain an important communication tool for many people.
