Answer
Brief Explanations:
In early electronic computing, hardware - specific helper files were often created by customers as there was less standardization. Computer operation involved mechanical switches and wires due to the technology level at that time. The hardware was bulky and expensive because of the large - scale components and limited manufacturing capabilities. Early computing was not very efficient or accurate, and required a lot of human intervention.
Answer:
