Intro to Computing - How Hardware Works
Explain why RAM is considered 'volatile' memory and how this affects saving work on a computer.
ARAM keeps data only while powered; unsaved work is lost if power fails
BRAM saves data permanently, so saving work is unnecessary
CRAM automatically backs up data to cloud storage
DRAM controls file saving on the hard drive
Step-by-Step Solution
Solution:

  1. Step 1: Define volatility of RAM

    RAM requires continuous power to hold data; it loses data when power is off.

  2. Step 2: Impact on saving work

    If work is not saved to permanent storage, power loss causes data loss.

  3. Final Answer:

    RAM keeps data only while powered; unsaved work is lost if power fails -> Option A

  4. Quick Check:

    RAM volatility means save work to avoid loss [OK]
Quick Trick: Save work because RAM loses data without power [OK]
Common Mistakes:
MISTAKES
  • Assuming RAM saves data permanently
  • Thinking RAM backs up data automatically
  • Confusing RAM with file management
