------------------------------------------------ Which of the following statements describes key differences between the peripheral devices of a standard desktop PC computer and a smartphone?

1. The smartphone has items normally thought of as peripherals, such as a keyboard and monitor, built in, whereas with the desktop computer the peripherals are largely external.

2. The desktop computer has peripherals such as a keyboard and monitor built in, whereas with the smartphone the peripherals are largely external.

3. The desktop is more likely to have peripheral devices built into the computer compared to the smartphone.

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.
