Question
Which generation of computers is associated with operating systems that required human operators to set switches?
Correct Answer
Option A is the correct answer.
Detailed Explanation
First-generation computers did not have an operating system; they required human operators to set switches to control the machine. This contrasts with later generations where operating systems became more automated and user-friendly.
Hint
In this earliest generation, the 'operating system' was literally a human being manually configuring the machine.
