Final answer:
Digital data refers to information represented in binary code, while a digital device uses digital signals and processes digital data.
Step-by-step explanation:
The terms 'digital data' and 'digital device' are related to the use of binary code in modern technology. Digital data refers to information that is represented using binary digits, or bits, which are either ones or zeroes. For example, when you take a photo on your smartphone, the image is converted into a sequence of binary digits that can be stored and transmitted digitally. A digital device, on the other hand, is a device that uses digital signals and processes digital data. This includes computers, smartphones, tablets, and other electronic devices that rely on binary code for operation.
