What is the purpose of RAM?

Explanation:
RAM is the fast, temporary working memory the CPU uses to store data and instructions while programs are running. Because RAM is volatile, all information is lost when power is removed, which is why permanent files stay on hard drives or SSDs. BIOS settings, on the other hand, are kept in non-volatile memory on the motherboard so they persist without power. RAM isn’t considered a non-volatile cache; the CPU’s caches are separate and even faster but much smaller. So, RAM’s purpose is to hold the active data and code the CPU needs access to quickly during operation.
