It encrypts data on hard drives to prevent access without the correct password.
16. Which is a BIOS security feature that can prevent data from being read from a hard drive even if the hard drive is moved to another computer?
17. What is one purpose of adjusting the clock speed within the BIOS configuration settings?
to allow a computer to run multiple operating systems in files or partitions
to change the order of the bootable partitions
to disable devices that are not needed or used by the computer
