What is RAM?

• A. Random Access Memory is high speed, volatile memory that can be read and written to
• B. Read Only Memory
• C. Magnetic tape storage
• D. Non-volatile disk

Answer: (A)

RAM, or Random Access Memory, is the fast, temporary workspace the CPU uses to hold data and instructions while a program runs. It can be read from and written to, which lets the processor update information quickly as it works. Because RAM is volatile, its contents disappear when power is removed, so the system must reload needed data from non-volatile storage when needed again. This distinguishes RAM from ROM, which is non-volatile and typically read-only; magnetic tape, a slow, magnetic storage used mainly for backups; and hard drives or SSDs, which are non-volatile disks used for long-term storage but are much slower than RAM. In short, RAM provides the quick, writable memory the system relies on for active tasks.
