Question 2

An example of an algorithm is to unplug the device, wait 30 seconds, and restart the device.

This sequence of steps represents a clear and defined procedure for resolving a common issue, illustrating the concept of an algorithm effectively.

A) Unplug the device, wait 30 seconds, and restart the device.

This option is correct as it lays out a specific set of instructions to solve a problem. It demonstrates the characteristics of an algorithm by providing a sequential method that can be followed to achieve a desired outcome.

B) The list contains apples, bananas, and oranges.

This option is incorrect because it merely states a fact about the contents of a list without providing a procedure or steps to follow. An algorithm requires a defined process, which this statement does not offer.

C) The sign of two integers determines the sign of the product.

While this option describes a mathematical rule, it does not present a step-by-step procedure to solve a problem. Algorithms involve specific instructions or actions, making this statement insufficient to qualify as an example of an algorithm.

D) A webpage uses an HTML file type.

This option is incorrect because it describes a characteristic of web pages rather than a sequence of steps to follow. It does not represent a procedure or algorithm, which requires a series of actions to achieve a result.

Conclusion

Option A is definitively the correct answer as it exemplifies a structured approach to problem-solving through a sequential process. The other options fail to meet the criteria of an algorithm since they either describe static facts or lack a defined sequence of actions. Thus, A stands out as the only choice that clearly illustrates what an algorithm is.
