Question

Why are some memories called ‘rovers’?​

Answer 1

Answer:

Better memory than ever

The computer is composed of equipment comparable to a high-end, powerful laptop computer. It contains special memory to tolerate the extreme radiation environment from space and to safeguard against power-off cycles so the programs and data will remain and will not accidentally erase when the rover shuts down at night.

On-board memory includes 128 MB of DRAM with error detection and correction and 3 MB of EEPROM. That´s roughly the equivalent memory of a standard home computer. This onboard memory is roughly 1000 more than the Sojourner rover from the Pathfinder mission had.
