Final answer:
Declarative knowledge in information processing technology involves propositional knowledge, which deals with factual truths that can be expressed in declarative sentences, as well as procedural knowledge regarding the actual performance of tasks.
Step-by-step explanation:
When examining the subject of epistemology in the field of information processing technology (IPT), specifically in the context of declarative knowledge, we look at propositional knowledge as a starting point. This type of knowledge deals with facts or truths that can be expressed in declarative sentences with a truth value, meaning they can be judged as either true or false. Among the different types of propositional knowledge, logical knowledge constitutes one such type, concerned with the truth value based on logic and reasoning processes.
An example of logical propositional knowledge is understanding that 'if all mammals breathe air, and dolphins are mammals, then dolphins breathe air' is a true proposition. Another type of knowledge relevant to IPT is procedural knowledge, which is more about 'know-how' and involves being able to perform certain tasks. For instance, one can have propositional knowledge of how a computer program should function theoretically, but procedural knowledge allows an individual to actually write and debug the program.
While procedural knowledge plays a significant role in technology and computing, it is essential not to overlook that both procedural and propositional knowledge are integral to the field and often interconnected, as understanding the facts about how systems work is foundational to being able to manipulate and create within the field of IPT.
