Which of the following actions is NOT a method to increase a computer's capacity?

Replacing software is not a method to increase a computer's capacity because capacity typically refers to the hardware-related resources of a computer, such as its memory, storage, and processing power. Increasing memory and adding external storage are direct ways to enhance a computer's ability to run applications and store data, thereby increasing its effective capacity.

Replacing components can also improve capacity by upgrading parts like the CPU or graphics card to better performance standards. However, while software updates or replacement can enhance performance or functionality, they do not physically increase the amount of memory or storage; thus, they do not increase the computer's capacity in the same way that hardware modifications do.
