What is phone?
A phone is an electronic device that lets you send and receive voice messages, text, photos, videos, and data over a distance. It works by converting sound into electrical signals, transmitting them through networks, and turning them back into sound at the other end.
Let's break it down
- Handset: The part you hold, containing a speaker and microphone.
- Display: A screen that shows text, images, and apps.
- Keypad/Touchscreen: Lets you dial numbers or interact with apps.
- Battery: Stores power so the phone can work without being plugged in.
- Processor: The “brain” that runs apps and handles tasks.
- Antenna & Radio Modules: Connect the phone to cellular, Wi‑Fi, Bluetooth, and GPS networks.
- Operating System (OS): Software layer (like Android or iOS) that manages hardware and runs apps.
