Which type of memory is saved when performing a file backup?

The correct answer is SRAM, which stands for Static Random Access Memory. When performing a file backup in a FANUC handling tool system, SRAM is the type of memory that is typically saved. This is because SRAM retains data that is actively being used and is necessary for the operation of the robot system, such as temporary settings, configurations, and program states that can change over time.

SRAM is volatile, meaning it requires power to maintain the stored information. Therefore, when a backup is performed, backing up the SRAM ensures that all operational data is preserved for restoration if needed. This is critical in industrial applications where losing configuration or operational data might disrupt productivity.

In contrast, other types of memory mentioned have different functions or characteristics. F-ROM (Flash Read-Only Memory), EEPROM (Electrically Erasable Programmable Read-Only Memory), and ROM (Read-Only Memory) serve roles in storing firmware or permanent data, but when it comes to actively managing and backing up the current state and settings of a robot system, SRAM is the primary focus.
