Final answer:
Windows CE device drivers can be classified as Monolithic and Layered. Monolithic drivers are large single-block drivers, while Layered drivers are composed of modular layers for easier updates and maintenance.
Step-by-step explanation:
The question addresses Windows CE device drivers, which have two types, namely Monolithic and Layered. This classification is based on how the drivers are constructed and integrated with the operating system. Monolithic drivers are large and incorporate multiple functionalities within a single driver, much like a single, large block of code (hence the term monolithic). On the other hand, Layered drivers are designed to be more modular, separating different functions into layers which interact with each other, allowing for greater flexibility and ease of updates.
The correct answer to the question is: a) Monolithic and Layered.
