RAM stands for Random Access Memory. What does RAM refer to?

• A. A type of computer memory where information is stored
• B. A plug-in device used to store information
• C. The set of programs that tell a computer what to do
• D. A worldwide connected system of computer networks

Answer: (A)

RAM is the fast, temporary workspace a computer uses to hold data and instructions while programs are running. It’s a type of memory that the processor can access quickly from anywhere in memory, which is why it’s called random access. Because RAM is volatile, its contents disappear when the power is off, unlike long-term storage like a hard drive that keeps data without power. This combination—being memory used for active tasks and being fast and temporary—is what RAM describes.

The other ideas don’t fit: a plug-in device used to store information points more to peripherals or expansion cards, not the memory directly used by the CPU. The set of programs that tell a computer what to do refers to software, not memory. A worldwide connected system of computer networks is the Internet, not RAM.
