Which type of system executes pre-defined tasks based solely on input commands without adjusting to outcomes?

The answer points to a system that operates without making adjustments based on the results of its actions. An open loop system fits this description perfectly. Such systems follow a set of pre-defined processes and execute tasks strictly based on the given input commands, without considering the output or the effects of those processes. This means that once the input is processed, there is no feedback mechanism that influences future actions or decisions.

In contrast, an adaptive system learns from outcomes and modifies its behavior accordingly. A control system typically includes mechanisms to regulate its output in response to feedback. Similarly, a feedback system relies on information about the output to make necessary adjustments to the system's operation. Therefore, the defining characteristic of an open loop system is that it does not incorporate feedback from the output to influence future inputs or actions, which is why it is the correct choice in this context.
