stand by: battery powered circuit is used when AC input fails
inline device: battery powered circuit is used continually

The switch on the back is the switch for the power supply only. The computer boots from the main power switch on the front. This particular method of switching was introduced with the ATX power supplies.
A no-break generator, also known as an uninterruptible power supply (UPS) or backup generator, is a system designed to provide continuous power without interruptions during a power outage. It seamlessly switches to battery or generator power when the main electricity supply fails, ensuring that critical equipment remains operational. This is particularly important for applications where even a brief loss of power can lead to significant disruptions or data loss. No-break generators are commonly used in data centers, hospitals, and other facilities that require reliable power.
The 2 main types of timber are Softwoods and Hardwoods.
The 3 main types of organic compounds used in society are alkanes, alkenes and alkynes
The two main types of rocket engines are Solid fuel rocket engines and Liquid fuel rocket engines.
the two main types of uninterpretable power supplies are: universal and uncompliant
the true UPS (called the inline UPS) and the standby UPS.

stand-by device and a in-line device
Uninterruptible power supplies (UPS) typically use sealed lead-acid batteries, although some models may also use lithium-ion batteries. These batteries provide backup power to the UPS when there is an interruption in the main power source, allowing for continuity of power supply to connected devices.

A UPS (uninterruptible power supply) works by providing backup power to electronic devices in the event of a power outage. It typically consists of a battery that stores power and an inverter that converts the stored DC power into AC power. When the main power source fails, the UPS switches to battery power to ensure continuity of power supply to the connected devices.
Dc Power Supplies converts AC to DC Two Main types 1)Linear : A simple circuit with diodes and capacitors 2)Switched Mode: sampling technique is used to convert AC to DC.
A UPS (Uninterruptible Power Supply) supplies a certain amount of power for a certain amount of time if the main electrical power is out. A surge protector does not. A UPS also serves to "even out" fluctuations in voltage, which are fairly common - most S/Ps do not do this. A S/P is there to protect against voltage SPIKES that might cause an overload, but they don't do a thing if the power goes out.
In the UK, the two main types of voltage in use are 230 volts for domestic supplies and 400 volts for industrial supplies.
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.
The name tells you - it supplies power to the device it is part of.
