Surge Protector
A surge protector protects a system against lightening strikes but not against sags or blackouts. Line conditioners also called power conditioners protect your computer against sags and brownouts. The UPS protects your computer against blackouts ~TiffyQT
Protects against potential electrical power problems by supplying a consistent level of electrical power to a computer. The battery is constantly recharging while the UPS is in use.
It's true that a surge protector would protect against surges like those caused by lightning strikes but would do nothing to help with sags and brownouts. To address both high voltage (surges) and low voltage (brownouts) you would need an uninterruptible power supply (UPS). A UPS provides clean current by powering your computer from the battery while simultaneously charging the battery from the electrical supply.
A fuse cannot protect 100% of the time against every possible event. It protects conductors and appliances from over currents in excess of the fuse's rating and that is all. It will not protect against a nearby lighting strike. It will not protect your TV's more sensitive components if protection built into the TV fails.
Online ups protect their computer equipment against electrical power browns outs and blackouts by using multiple power generators that have a back up system.
