History
↓↓
The telephone is a device that converts sound into electrical signals to enable voice communication over distances.
Its invention is credited to Alexander Graham Bell, who was awarded the first patent in 1876.
Early telephones were connected by manual switchboards operated by human operators.
In the late 19th and early 20th centuries, telephone networks expanded rapidly in cities and rural areas worldwide.
The development of rotary dials, touch-tone systems, and eventually mobile and digital phones revolutionized communication.
Today, telephones, including smartphones, are essential global tools for personal, business, and emergency communication.
