A landline phone is a traditional telephone that connects to the public switched telephone network through physical wires. It typically consists of a handset and a base unit, allowing users to make and receive calls from a fixed location. Landline phones are known for their reliability and clear sound quality. Unlike mobile phones, which rely on cellular networks, landline phones do not require charging and can function during power outages if connected to a backup power source. They are often used in homes and businesses for everyday communication, providing a stable option for voice calls without the need for internet connectivity.
