Rom (read only memory) is a memory clip into which fixed data is written permanently at the time of its manufacture.
Bootstrap program refers to a computer start up program which is held in the form of a Rom.
The reasons why it is held in Rom include:
i) New data cannot be written into the memory and so the data on the memory clip is unchangeable and irremovable. This means that data cannot be corrupted and so the system maintains its consistency.
ii) Rom is a ‗non volatile‘ memory which means that its contents do not disappear when the computer power source is switched off. This ensures that data is securely held and suffers no risk of getting lost. In this case, Rom chips will consist of items of software such as the computer operating system and various pieces of translation software.
