ROM chips control the startup of the computer
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.

Rom
No, it's not required as part of the computer, it's an optional component
Read-only memory (ROM) in a computer is a type of non-volatile memory that stores data permanently and cannot be easily modified or erased. Unlike random-access memory (RAM) which is volatile and temporary, ROM retains its data even when the computer is turned off. ROM is typically used to store essential system software and firmware that is necessary for the computer to function properly.
ROM
BIOS provides the boot-up process for a computer. It is part of ROM.
When purchasing a computer, you need only be concerned with the RAM. All computers have ROM, but for the most part, the type or amount of it will make no impact on any aspect of the computer's operation. Since no applications you run are going to rely on ROM for storage, that leaves only RAM.
If I was to purchase a computer that is a average desktop computer how much RAM and Rom should I have?
no, ROM cannot be wriitten
Well, isn't that just a happy little question! ROM and a secondary computer both store information for your computer to use. ROM holds essential instructions that never change, like a sturdy tree rooted in the ground. A secondary computer, like a hard drive, stores data that can be added or removed, much like the ever-changing landscape of a beautiful painting.
