Linear power supply - An AC powered linear power supply usually uses a transformer to convert the voltage from the wall outlet (mains) to a different, usually a lower voltage.
In the past mains electricity was supplied as DC in some regions, AC in others. Simple, cheap, linear power supplies running directly from either AC or DC mains, often without a transformer used. They used a rectifier and capacitor filter; the rectifier was essentially a conductor, having no sudden effect when operating from DC.
A switched-mode power supply (SMPS) works on a different principle. AC mains input is directly rectified without the use of a transformer, to obtain a DC voltage. This voltage is then sliced into small pieces by a high-speed electronic switch. The size of these slices grows larger as power output requirements increase.

What is the purpose of a UPS battery backup?
A UPS is an abbreviation for an "Uninterruptible Power Supply". The purpose of this device is to provide power when the main power source fails. UPS battery backups are used to provide power for computers, data centers and various other types of equipment. Typically the back-up is used with equipment that cannot have a disruption in the power supply, or equipment which may be damaged if there is a disruption in the power supply.

What box inside a computer case that supplies power to the motherboard?
The power supply. It is a Switched Mode Power Supply Unit. SMPSU. It provides three types of voltage at differing amperage capacities, from the mains supply. 5v Heavy duty +12v light duty -12v light duty. The wires are color coded as to what voltage they carry and end in plugs which attach to the various hardware inside the cabinet.
