The Master Boot Record (MBR) consists of the master boot code, the partition table, and the signature word. The signature word, also known as the boot signature, is a specific 2-byte value (0x55AA) located at the end of the MBR that indicates the presence of a valid bootable disk. This is a critical component in the MBR structure, ensuring that the disk is recognized as bootable by the system.
The correct answer is A. Signature word because the Master Boot Record (MBR) typically consists of the following components: Master boot code Partition table Signature word (also known as the boot signature) The signature word is a specific 2-byte value (0x55AA) at the end of the MBR that indicates the presence of a valid bootable disk. The disk signature (option D) is a unique identifier used by the operating system to distinguish between different disks, but it is not a fundamental component of the MBR structure as defined in the CHFI v10 textbook.
The structure of MBR consists of three parts: Master Boot Code or Boot Strap – It is an executable code and responsible for loading OS into computer memory. It consists of a data structure of 446 bytes. Partition Table – It maintains the data of all the hard disk partitions and consists of a data structure 64 bytes Disk Signature – It is located at the end of the MBR and contains only 2 bytes of data. It is required by BIOS during booting.
