'Bootstrap Program' কোথায় সংরক্ষিত থাকে?

Bootstrap Memory:
Many microcomputers and most larger computers do not have their operating system programs stored in ROM.
Instead, these programs are stored in external mass memory, usually a magnetic disk.
A relatively small program, called a bootstrap program, is stored in ROM.
When the computer is powered on, it will execute the instructions that are in this bootstrap program.
