An autonomous deep-sea research submarine uses an on-board computer system to control its navigation, capture high-resolution sonar images, and log telemetry data. The system is equipped with a high-capacity solid-state drive (SSD) as secondary storage, alongside a much smaller capacity of volatile Random Access Memory (RAM).
Explain two reasons why the capacity of the secondary storage (SSD) must be significantly larger than the capacity of the RAM in this system.
