Final answer:
The main difference between the peripherals of desktop PCs and smartphones is that desktop peripherals are external, while smartphones have built-in peripherals like keyboards and touchscreens.
Explanation:
The key differences between the peripheral devices of a standard desktop PC and a smartphone are centered around their design and intended use. For a desktop PC, peripherals such as a keyboard and monitor are largely external. This is because a desktop is designed to utilize a consistent source of electric power and fits on or beneath a desk, hence not intended to be highly portable. These peripherals extend the computing functionality and include input, storage, and output devices like mice, keyboards, monitors, and printers.
In contrast, a smartphone integrates many peripherals, making them internal or built-in. The primary input device for smartphones is the touchscreen, which combines the functionality of a mouse and a keyboard through gestures or selections made by fingers or a stylus. Smartphones are also equipped with built-in microphones and cameras of varying qualities for capturing sound and images and for communication purposes. These distinctions make the smartphone a highly portable device, combining voice, text, email, and personal computing into a single unit that can access the internet and run apps.
Therefore, the correct statement that describes the key differences is: The smartphone has items normally thought of as peripherals such as keyboard and monitor built in, whereas with the desktop computer, the peripherals are largely external.
