A telefonok, or telephone, is a device that allows people to communicate over distances by converting sound into electrical signals. These signals are transmitted through wires or wirelessly, enabling conversations between individuals who are not physically present in the same location. Modern telefonok come in various forms, including landline phones and mobile phones. Mobile phones, often referred to as okostelefonok or smartphones, offer additional features such as internet access, messaging, and applications, making them versatile tools for communication and information sharing.
