A software program for initiating the operation of a computer.
The function of the program is to set up the input and output (I/O) devices and load the OPERATING SYSTEM from a disk, cassette, or built-in ROM.
Because the computer gets itself up and going from an inert state, it could be said to lift itself up "by its own bootstraps" -- this is where the term Boot originates.
