Why is programming code that is stored in ROM BIOS sometimes copied to RAM What is?

Programming code stored in ROM BiOS is sometimes copied to RAM to enhance system performance and speed up execution. RAM is significantly faster than ROM, allowing the CPU to access and execute the BiOS code more rapidly. This practice also enables the system to modify or update the BiOS settings dynamically during operation, facilitating better management of hardware components. Additionally, accessing BiOS functions from RAM can reduce wear on the ROM, extending its lifespan.
