The area that holds all the startup instructions a computer needs to start is the BIOS (Basic Input/Output System) or UEFI (Unified Extensible Firmware Interface) firmware. This firmware is stored in a non-volatile memory chip on the motherboard and is responsible for initializing hardware components and loading the operating system during the boot process.
A computer accesses ROM (Read-Only Memory) when it needs to retrieve essential instructions and data during the startup process or when performing basic functions.
Because - the computer needs a specific set of instructions to start -up. The instructions held in ROM initialise the hardware and instruct the computer to load the operating system (and where to find it on the hard-drive).
A computer needs instructions to perform a task. There are many aspects of a computer, such as all the internal parts, the peripherals, and the software components. A computer needs hardware to store and process information, and needs software instructions to do anything for us. If there was no software at all on a computer it would merely be a box of parts. There would be no software telling the computer to show information on the output, and no software to accept instructions from the input.

The BIOS.
Yes, ROM (Read-Only Memory) commonly holds the computer's firmware, which includes the basic instructions for booting the operating system. However, the operating system itself is typically stored on a hard drive or solid-state drive and loaded into RAM during operation. ROM retains its contents even when the power is off, making it suitable for storing essential system software that needs to be accessed at startup.
When a computer starts up it needs to check various things that may stop the computer from starting properly. These instructions are contained in the micro-processor that is installed as part of the computer. These instructions are long, detailed, and what most people normally do not worry about
to prevent corruption of other programs, it needs to be uninstalled correctly. You could accidently disable a program your computer needs if you just dump the file, as some software uses shared data files.

If you use 1-Click (Answers), you might find, as I did, that if it's in your list of Startups you will probably need to 'exit' it (in the taskbar) *first, before you will be able to have the 'Turn Off Computer' take effect. [(Start/ Run/type 'msconfig' and enter/ Startup (tab)/ Startup Items (checked boxes)]
it is the ROM . The ROM has firmware which controls the booting up of the computer during start up. The booting software, known as BIOS (Basic Input Output System) give instructions to the POST (Power On Self-Test) which then runs tests to on the computer to make sure that all the devices are well connected to the computer. Sometimes this process is so fast that when observed, it appears as if there is are no tests being run by the POST process.
It is common knowledge to that almost any computer store holds ink cartridges because they are essentials for computer needs. Just a drive to the nearest computer store.
