What can be used to protect a computer system from data loss during an unexpected loss of electric power?
Cloud storage service
Portable generator
Surge protector
Uninterruptible power supply (UPS)
An uninterruptible power supply (UPS) provides emergency battery power when the main power source fails, allowing time for an orderly shutdown of computers and connected equipment and preventing data loss and hardware damage. Surge protectors guard against voltage spikes but do not supply power during an outage. Cloud storage offers off-site backups but cannot keep a system running when the power fails. Portable generators can supply power for longer periods but take seconds to minutes to start, leaving an immediate gap in protection.
