Multiple Choice Questions: Memory in Computers for Kids

📚 Quick Study Guide

• 💾 Memory: Computer memory is where the computer stores data and instructions it needs to work. Think of it like the computer's short-term memory.
• ⚡ RAM (Random Access Memory): This is the main memory that the computer uses when it's running. It's fast but loses its data when the power is turned off (volatile).
• 💾 ROM (Read-Only Memory): This memory stores permanent instructions that the computer needs to start up. It keeps its data even when the power is off (non-volatile).
• 💽 Storage Devices: These are used for long-term storage of data, like hard drives (HDDs) or solid-state drives (SSDs).
• 🔢 Bits and Bytes: Memory is measured in bits and bytes. 8 bits make 1 byte. Kilobytes (KB), Megabytes (MB), Gigabytes (GB), and Terabytes (TB) are used to measure larger amounts of memory. $1 KB = 1024 Bytes$, $1 MB = 1024 KB$, $1 GB = 1024 MB$, $1 TB = 1024 GB$.
• ⏱️ Volatile vs. Non-Volatile: Volatile memory (like RAM) requires power to maintain the stored information. Non-volatile memory (like ROM and SSDs) retains the information even without power.
