Random Access Memory (RAM) serves as volatile, temporary storage for data and applications that the CPU is actively using. When a computer is running applications, they are loaded from permanent storage into RAM for fast access by the processor. Hard Disk Drives (HDDs) and Solid-State Drives (SSDs) are forms of non-volatile, permanent storage where files are saved for long-term access. The Central Processing Unit (CPU) executes instructions and processes data but relies on RAM for holding the active data it needs.
