FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -A master boot record (MBR) is a special type of boot sector at the very beginning of partitioned computer mass storage devices like fixed disks or removable drives intended for use with IBM PC-compatible systems and beyond. The concept of MBRs was publicly introduced in 1983 with PC DOS 2.0.

Detailed explanation-2: -The Master Boot Record (MBR) is the information in the first sector of a hard disk or a removable drive. It identifies how and where the system’s operating system (OS) is located in order to be booted (loaded) into the computer’s main storage or random access memory (RAM).

Detailed explanation-3: -The boot sector is also referred to as the Master Boot Record (MBR). The MBR contains a partition table, which stores information on which primary partitions have be created on the hard disk so that it can then use this information to start the machine.

Detailed explanation-4: -The three main components of the master boot record are the master partition table, master boot code and disk signature.

Detailed explanation-5: -In simple terms, the BIOS loads and executes the Master Boot Record (MBR) boot loader. When you first turn on your computer, the BIOS first performs some integrity checks of the HDD or SSD. Then, the BIOS searches for, loads, and executes the boot loader program, which can be found in the Master Boot Record (MBR).
