What is the purpose of the 'refresh' process in DRAM?

To store more data.

To prevent data loss by re-charging the capacitors.

To speed up the access time.

To rewrite the data to a different location.

DRAM capacitors lose their charge over time; therefore, the refresh process periodically restores the charge.
