What is computer memory? Explain.
Understand the Problem
The question is asking for an explanation of computer memory, specifically the concepts of primary and secondary memory, along with their functions and characteristics.
Answer
Computer memory stores data and instructions temporarily (RAM) or permanently (hard drives).
Computer memory is the storage system within a computer used to save data and instructions either temporarily or permanently. Primary memory (RAM) is volatile and fast, storing data for quick access during processing. Secondary memory (such as hard drives) is non-volatile and used for long-term data storage.

Computer memory is the storage system within a computer used to save data and instructions either temporarily or permanently. Primary memory (RAM) is volatile and fast, storing data for quick access during processing. Secondary memory (such as hard drives) is non-volatile and used for long-term data storage.
More Information
Computer memory is crucial for a computer's functionality, allowing data processing and retrieval. Primary memory (RAM) allows fast data access but loses its contents when powered off. Secondary memory provides persistent storage, preserving data even without power.
Tips
A common mistake is confusing memory with storage. Remember, primary memory (RAM) is volatile and for immediate data access, while secondary memory is non-volatile, for longer-term storage.
