The iPhone architecture consists of several components, including the A-Series chips, memory, storage, sensors, and radios. The A-Series chips, developed by Apple, are the central processing units (CPUs) that enable the device to run applications and processes. In recent models, these chips are also integrated with graphics processing units (GPUs) and neural engines that enable advanced machine learning and artificial intelligence capabilities.

The memory, or RAM, provides temporary storage for data and instructions that are actively being used by the device, while the storage, typically in the form of flash memory, stores files and data that persist even when the device is turned off.

Sensors, such as the accelerometer, gyroscope, and proximity sensors, enable the device to detect and respond to physical movements and environmental conditions. The radios, including Wi-Fi, Bluetooth, and cellular networks, enable communication and data transfer between the device and other devices or networks.

All of these components are tightly integrated and optimized to work together to provide a seamless and efficient user experience on iPhones.
