Laptops, all-in-one desktops, and smartphones usually have _____.

Laptops, all-in-one desktops, and smartphones typically come equipped with internal microphones to facilitate a range of functions, such as video conferencing, voice recognition, and hands-free communication. This feature is essential for users who rely on online meeting tools or virtual assistants like Siri or Google Assistant, as the internal microphone allows these devices to pick up sound without the need for additional external equipment.

While external speakers, touch screens, and physical keyboards are common in many devices, they are not universally present in all laptops, all-in-ones, or smartphones. For instance, not all laptops have integrated touch screens, and many all-in-one desktops might not include physical keyboards in their design or default configuration. Therefore, the presence of internal microphones is a more consistent characteristic across these devices, making this option the most accurate.
