The correct answer is: A. Loads system files to RAM.
The boot startup process is a series of steps that the computer takes when it is turned on. The first step is to load the BIOS, which is a small program that is stored on a chip on the motherboard. The BIOS then initializes the hardware and loads the operating system from the hard drive. The operating system then takes over and loads the rest of the system files into RAM.
The other options are incorrect because:
- Option B: Checks the computer connections is not part of the boot startup process. This is usually done by the operating system after it has been loaded.
- Option C: Clean up the computer memory is not part of the boot startup process. This is usually done by the operating system when it is idle.
- Option D: Prepare the computer ready is not a specific step in the boot startup process. It is a general description of what the boot startup process does.
