Understanding Computer Memory

Computer memory is the essential workspace where your system processes data. It comes in two primary forms: RAM (Random Access Memory) and storage. RAM is volatile, meaning it temporarily holds the data of actively running programs and the operating system for incredibly fast access by the CPU. This is your computer's short-term memory, which gets cleared when the power turns off.

For long-term data retention, computers use storage drives like SSDs (Solid State Drives) or HDDs (Hard Disk Drives). This non-volatile memory preserves your files, software, and operating system even when the computer is shut down.
