Explanation:

A technological system is a system that consists of components constructed to work together in order to process an input to an output/result. These components or parts that make up a technological system are as follows: input, processing, output and feedback.

- The input is what is taken in by the system.

- The process is the series of occurrences conducted by the internal parts of the system to bring about an output.

- The output is the final result of the system.

- The feedback is how the system should work in comparison to how it is working.

Among all these parts of a technological system, the part that is OPTIONAL i.e the system can function without, is the FEEDBACK.
