Prepare for this practice
Learn why a computer needs both fast working space for active tasks and persistent space for files and programs.
Review Computer memory and storage before starting →Ideas to recall
- Main memory holds data and instructions currently needed by running programs.
- Persistent storage keeps files and programs when power is removed.
- RAM capacity affects how much active work a system can hold efficiently.
- Storage capacity and storage speed affect how much data can be kept and how quickly it can be accessed.
Use these ideas to reason through each question; answer-specific explanations appear only after you check a response.
