A phone is a device used for communication, allowing people to talk to each other over long distances. It converts sound into electrical signals, which are transmitted through wires or wirelessly. Modern phones often include additional features like texting, internet access, and applications, making them versatile tools for daily life. There are two main types of phones: landline phones, which are connected to a physical line, and mobile phones, which use cellular networks. Mobile phones, also known as cell phones, have become increasingly popular due to their portability and multifunctionality, serving as cameras, music players, and more.
