A. POST
B. CMOS
C. RIPT
D. PMOD
🧠 Explanation:
When you turn on a computer, the BIOS runs a program called POST. It checks hardware like RAM, CPU, and storage to make sure everything works fine. If something’s wrong, it shows an error code. This is super important because it helps the computer start properly. You’ll find POST in every PC or server, ensuring they run smoothly for tasks like studying, gaming, or office work. Without it, hardware issues could crash the system, so it’s key in IT and electronics for reliable performance.
