What type of RAM is described as temporary and requiring frequent refreshing?

• A. Static
• B. Volatile
• C. Dynamic
• D. Permanent

Answer: (B)

The term that best describes RAM as temporary and requiring frequent refreshing is "dynamic." Dynamic RAM (DRAM) is a type of volatile memory that stores each bit of data in a separate capacitor within an integrated circuit. Since capacitors tend to leak charge, DRAM requires the data to be constantly refreshed or rewritten every few milliseconds to maintain the stored information. This need for refreshing is what makes it dynamic and distinguishes it from static RAM (SRAM), which does not require such frequent refreshing and retains data as long as power is supplied. In terms of the characteristics of memory types, "volatile" accurately describes DRAM since it loses its contents when the power is turned off. However, the specific emphasis on "requiring frequent refreshing" directly points to the nature of dynamic RAM rather than just its volatility. Permanent memory, on the other hand, does not require refreshing and retains data even when the power is off, making it distinct from dynamic RAM.
