A mobile phone contains a microprocessor, memory storage, battery, microphone and speaker, touch screen, and antenna that allow it to process information and communicate over a cellular network. The microprocessor focuses on the display, keyboard, and control signals while connecting to the network via the antenna. The memory and flash storage hold the phone's operating system and files. The battery powers the components and the microphone and speaker enable voice communication.
