with out that devices we can not read the data
The part of computer memory that is permanent and unchanging is typically referred to as Read-Only Memory (ROM). Unlike volatile memory like RAM, which loses its data when power is turned off, ROM retains its contents even when the computer is powered down. It is used to store firmware, which is essential for booting the computer and performing hardware initialization. This makes ROM crucial for the system's basic functions.
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
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.
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.
