What is a key feature of digital keyboards?

A key feature of digital keyboards is that they are designed primarily for typing and inputting data. This functionality is essential for users who need to interact with their devices, whether it's for composing text, coding, or entering information in various applications. The layout and design of digital keyboards facilitate efficient data entry, making them an integral part of any computer or device setup.

The other options pertain to features that are not inherent to digital keyboards. For instance, while some digital devices may provide internet access, this is not a characteristic of keyboards themselves. Similarly, keyboards do not have the functionality to print photos or enable video recording, as these actions require different types of hardware or software. Thus, the primary and defining purpose of digital keyboards is their capability for typing and data input.
