Usually none.
Long ago BIOS(which isn't really part of an OS...) was stored on ROM.
These days you've usually got your OS installed on Hard Drive or a SSD drive.
What else can I help you with?
What part of the operating sytem is stored on ROM?
Most computers nowadays do not store any portion of the operating system in ROM. Among those that did and still do, only the kernel and basic system libraries are placed in ROM.
Where is the operating system stored in a handheld device?
ROM
Where in the cellphone that the operating system stored in?
ROM - the read-only memory
Where is the The operating system of a cell phone is stored?
read-only memory
Where is the operating system of a cellphone stored?
circut board - the read-only memory (ROM)
Where is the operating system stored in the Cow?
ROM(read only memory) is the place where the operating system is stored in the computer. == == Ok, it doesn't take Einstein to realise that ROM cannot be updated. So if you want the ability to upgrade an operating system, it can't be on ROM. Also consider disk costs v memory costs. Again, you do not need to be a Nobel Prize winner to figure it out.
Where is the operating system of a cell phone stored?
It is typically burned into a tiny ROM chip on the phone's circuit board.
What is stored on a ROM chip that is responsible for loading the operating system from its permanent location on the hard drive into RAM?
BIOS
What is the importance of ROM in the Operating system?
ROM - Read Only Memory, is a non-volatile section of memory which contains the programs which will start running when the computer is first turned on. These ROM programs could contain the entire operating system, or could start the basic input/output functions which load the operating system in from another location, such as stored on a disk.
Why is an operating system software handed from hard disk then a Rom chip?
The operating system has nothing to do with the ROM chip
Which computer first stored its operating system in rom?
This is hard to say precisely. However the Minuteman I and II guidance computers stored their software on read only tracks on a harddisk platter, and the Apollo guidance computer stored its software in core rope ROM. But neither of these actually had an operating system, their software ran directly on the hardware with no intermediate layers.
Some advantages of having the operating system stored on backing store rather than in ROM?
Ok, it doesn't take Einstein to realise that ROM cannot be updated. So if you want the ability to upgrade an operating system, it can't be on ROM. Also consider disk costs v memory costs. Again, you do not need to be a Nobel Prize winner to figure it out.
