During boot, when the processor loads the operating system into RAM, what is the resulting state of the OS?

• A. The computer powers down
• B. The operating system becomes active in memory
• C. The display driver is reinstalled
• D. The BIOS checks the RAM

Answer: (B)

When the OS is loaded into RAM and begins executing, it becomes active in memory. The system firmware (BIOS/UEFI) first performs checks and then loads the OS into RAM, handing control to it so the OS starts running and manages hardware and software. This active state means the OS is now running and responsive, using RAM to hold its code, data, and processes. The other options don’t describe what happens to the OS: powering down is the opposite of booting, a display driver is typically loaded after the OS is running, and RAM checks happen during the firmware’s POST phase, not as the OS’s resulting state.
