During boot-up, the memory test: A. Is a superfluous step that should be ignored B. Checks and verifies that contiguous memory is installed C. Is an operational error D. Displays what memory is installed, but nothing else E. None of the above

The correct answer is: E. None of the above

During boot-up, the memory test checks the integrity of the RAM installed in your computer. It does this by writing a pattern of data to each memory location and then reading it back to verify that the data is correct. If any errors are found, the memory test will display an error message and the computer will not boot.

Option A is incorrect because the memory test is an important step in ensuring that your computer is working properly. Option B is incorrect because the memory test does not check for contiguous memory. Option C is incorrect because the memory test is not an operational error. Option D is incorrect because the memory test displays more than just what memory is installed.
