What do you understand about a Bootstrap Program in Operating Systems? |
|
Answer» A Bootstrap Program is usually a program that initializes the operating system during the startup of the computer system, that is, the first program that is run when a computer system boots up. The operating system is loaded using a METHOD or application known as booting. Overall, the performance and functionality of the operating system are solely dependent on the bootstrap PROGRAMME. It is entirely stored on the disc in boot blocks at a certain location. It also locates and loads the kernel into the main memory, after which the program begins to run. As we can SEE in the image GIVEN below, the Bootstrap Program resides in the Read-Only Memory (ROM) of our COMPUTERS and they are the ones to first read the Operating Systems and load it into the RAM (Random Access Memory) of our computers. Only after that, the operating systems can start other devices of the computer like the Graphics cards, keyboards, mouses, etc. |
