What do you mean by MAR and MBR in computer organization?
MAR-memory address register used stored the address of the memory loaction MBR- memory buffer register is the actully data.
What takes control of the boot process from the system bios?
The MBR takes control of the boot process from the sytem bios.
What is the function of mbr?
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.
How does a computer BIOS find the MBR?
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.
What is the boot start process in windows operating system?
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.
