Which partition scheme is most commonly associated with BIOS-based systems?

• A. GPT
• B. MBR
• C. exFAT
• D. NTFS

Answer: (B)

BIOS-based systems historically boot using a simple partitioning layout defined by the Master Boot Record. This scheme places boot code and a small partition table in the first sector of the disk and typically supports up to four primary partitions (or three primaries plus one extended partition containing logical drives). It also carries a practical size limit around 2 TB for disks with 512-byte sectors, which matches the era when BIOS was the standard boot method. GPT, by contrast, was designed to work with the newer UEFI boot process, allowing many more partitions and far larger disks. The other two options aren’t partition schemes at all; they’re file systems used to organize data on a partition or drive.
