The master boot record (MBR) is an important part of the computer’s boot process. What is one of the items contained in the MBR?
A) A table of the computer’s primary partitions
B) A list of hard drive controllers inside the computer
C) A summary of operating system memory locations
D) A table of BIOS capabilities
The answer: A) A table of the computer’s primary partitions
For the master boot record to start the computer from an active partition, it has to know the location of an active boot partition.
The incorrect answers:
B) A list of hard drive controllers inside the computer
Controller information isn’t stored inside of the master boot record.
C) A summary of operating system memory locations
This sounds like a very high-tech answer, but it has nothing to do with the master boot record.
D) A table of BIOS capabilities
The BIOS doesn’t contain a description of boot locations.
