Question

The boot program is a simple code that is stored in

Answer 1

According to the wikipedia entry, a bootloader is a small program stored in ROM(a part of the main memory(RAM), isn't it??) which can only be read and not erased. I am a little puzzled here. Does this mean that every RAM we buy has a bootloader installed by default? And also, I read from a book which says that there is typically an area called the MBR (Master Boot Record) on the hard drive which includes a bootloader...

Answer 2

The boot program is a simple code that is stored in ROM memory.

• ROM memory is used to store read only files.
• When the computer is starting up / restarting / booting specific set of instructions are loaded , those instructions are stored in ROM.
• The boot code is the very first code to get executed on booting.
• Since ROM is non- volatile, i.e. either on system crash or power failure the boot code wont be affected.
