MAR-memory address register used stored the address of the memory loaction
MBR- memory buffer register is the actully data.
A computer's BIOS (Basic Input/Output System) is the heart of most modern personal computers. It is the part of the system that executes when a computer is first turned on, before any other programs or software are run. It ensures that the computer is set up correctly and is able to run properly, at least until subsequent programs and software are run. One such set up is the MBR (Master Boot Record), which is on the primary system device, commonly, but not always, a hard disk. Once the BIOS determines where the primary system device is located, it then uses that device's information to locate the area where the MBR resides (also referred to as the "boot sector"), examines it for errors, computer viruses, etc, and then allows the MBR to run; on most systems, this will initiate the computer's operating system, which is the part most commonly seen and familiar to that computer's user.
When MBR fails then the operating system will not load.
Well, assuming you mean "Master Boot Record". The master boot record is a 512 byte strip of data on a disk which contains, along with a few other things, the partition table for the disk in question and the bootstrap info for the operating system AND the disk identification. The last one is not always used. The MBR is very important.
The MBR takes control of the boot process from the sytem bios.
In Windows Operating System when system is powered on then power is supplied to BIOS Chip on Motherboard. BIOS checks all devices and their firmwares and looks for the MBR code on First Bootable device or bootable device found in order as configured in BIOS. MBR the first sector on bootable media directs to the Bootloader program. Bootloader program loads the Windows Kernel and then Windows OS takes control in Memory and Manages the Operating System's features.

Full form of MBR is Master Boot Record in computer hardware field...
BIOS reads the MBR.
I our company's case I understood it to mean "member". I was the contact person for our Limited Loss Company, and MBR was inserted after my name in the official EIN document. Furthermore, an IRS document found in the internet has this: "A single member or sole member LLC account will contain the words "SOLE MBR" or "SINGLE MBR" within the Sort Name line as shown on CC INOLES" So: MBR = member.
The Master Boot Record (MBR) is stored at the beginning of your hard drive (in the first 512 bytes.) The MBR contains information about the beginning and ending of each partition, which partition contains the operating system for booting, and other valuable information about the disk layout. Your computer will not boot up if your MBR is corrupt or missing.

The most common is when the sector signature is damaged or removed, which results in the infamous error message "Operating system not found." If the first sector is damaged, then you will just get a black screen on boot. The Master Boot Record (MBR) will only execute on boot. It is normal for a computer to function fine if its MBR is edited while the computer is active. Be very careful! A damaged MBR can be fatal to the contents of your hard disk drive (HDD); recovery may not be possible.

The instructions are stored in the Master Boot Record (MBR).
