POST

Explanation:

POST stands for Power On Self test. The process of booting the system involves performing the self test POST. POST involves testing the computer hardware which are required for proper functioning of the computer. If the POST test fails, the computer performs the necessary action required for the proper functioning of the computer. It immediately raises alarm (beeps). Different number of beeps represents different devices which are having trouble. So, option (D) is correct option. Option (A) IDE is not the test. So, option (A) is wrong option. Option (B) POTS is not the test. So, option (B) is wrong option. Option (C) QoS is not the test. So, option (C) is wrong option.
