Final answer:
A device-based automation tool is more reliable during internet connectivity issues and offers better data security and privacy since it processes and stores data locally.
Step-by-step explanation:
One advantage a device-based automation tool has over a cloud-based automation tool is that it provides reliability when connectivity issues arise. For instance, a device running automation tasks locally doesn't rely on an Internet connection, thus it's not susceptible to frustrations such as a website not loading or a dropped cell phone call. Additionally, with device-based automation, sensitive data can be processed and stored locally, which can be a significant advantage in terms of data security and privacy.
