Multiple Choice Questions on Volatile and Non-Volatile Memory

📚 Quick Study Guide

• 💾 Volatile Memory: This type of memory requires power to maintain the stored information. If the power is lost, the data is erased. RAM (Random Access Memory) is the most common example.
• ⚡ RAM Types: Includes SRAM (Static RAM) and DRAM (Dynamic RAM). DRAM needs to be refreshed periodically.
• 💡 Non-Volatile Memory: This type of memory can retain stored information even when not powered. Examples include ROM (Read-Only Memory), flash memory (like USB drives and SSDs), and magnetic storage (hard drives).
• 📝 ROM Types: Includes PROM (Programmable ROM), EPROM (Erasable PROM), and EEPROM (Electrically Erasable PROM).
• ⏱️ Access Time: Volatile memory generally has faster access times compared to non-volatile memory.
• 💰 Cost: Volatile memory is often more expensive per bit than non-volatile memory.
• 🔄 Usage: Volatile memory is used for active processes and data, while non-volatile memory is used for long-term storage.
