The Master Boot Record (MBR) is used on Mass storage disks, such as hard drives, which are designed to hold multiple partitions. See related link, below.

MBR (Master Boot Record) - this is because prior to windows vista all x86 based computers used the MBR partition style only.
MAR-memory address register used stored the address of the memory loaction MBR- memory buffer register is the actully data.
When MBR fails then the operating system will not load.
The Master Boot Record (MBR) scheme has a limit of 2TB for the maximum partition size. Additionally, MBR only supports up to four primary partitions or three primary partitions and one extended partition with multiple logical partitions within it. Modern systems often opt for the newer GUID Partition Table (GPT) scheme, which does not have these limitations.
Full form of MBR is Master Boot Record in computer hardware field...
MBR - Master Boot Record
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.
