What is Bootstrap and Bootstrap Loader...?
« on: May 06, 2015, 04:02:57 AM »
Bootstrap: To start a computer by loading its OPERATING SYSTEM from disk storage into memory. The name alludes to the seeming absurdity of trying to lift oneself off the floor by pulling on one's own bootstraps - since it is the operating system that enables a computer to read disks, then loading itself from disk would seem to be a similar impossibility. This paradox is resolved by the presence of a small program called the BOOTSTRAP LOADER, which resides permanently in the computer (stored in a ROM chip) and contains just sufficient code to read the rest of the operating system from disk. This process is informally called 'booting' or 'booting up' the computer.
