What Is Stored In Computer ROM?

The computer ROM is typically the location where operating system code and bootstrap code are stored. Since this is code that does not change often, it is stored in non-volatile memory so that its contents will not have to be reloaded from the disk each time power is lost.

The computer read-only memory (ROM) chips back up the computer software, which manages all operations of a machine, including executing instructions and processing data. Storing these functions in ROM saves valuable space on the less-secure hard drive. The innards of an old IBM laptop illustrate how computers work at their most basic level.
