As the name suggests, the Uninterruptible Power Supply is an appliance that is used to provide a continuous supply of power to an electrical device. It can supply the device even when the main source is temporarily shut down, as during a blackout. At such times, it provides the device with its own stored energy. Thus, it ensures that the device continues functioning even if the primary source of electrical supply is not able to provide the power required for its functioning. This is very important to improve efficiencies of workplace environment that rely largely on electric supply, such as an office that uses computers.

Types

There are three main types of UPS, based on their method of providing supply.

Standby UPS, also known as the Offline UPS – This is the most basic type. It works in the following manner – As long as the external electrical supply is on, it remains inactive, though it keeps on charging itself. However, if there is any ebb in the amount of power being supplied to the device, the UPS will take over and supply current itself. This will continue until the primary supply is back to normal. When that happens, the uninterruptible supply will

What is computer hardware? Hardware components like the monitor, keyboard, CPU (Central Processing Unit), mouse, and other I/O (Input-Output) devices constitute a computer. The working of the monitor, keyboard, mouse, and I/O devices depends largely upon the CPU. Due to some minor causes, like loose connections or dust saturation, any of them can stop functioning.

Faults occurring in the CPU are most hazardous, as it has a very complicated structure. The CPU is an assembly of the motherboard, hard disk drive (HDD), random access memory (RAM), compact disc-read only memory (CD-ROM) drive, and the floppy drive. Unless you are well-acquainted with the CPU hardware, it is extremely difficult to pinpoint exactly where the fault has occurred. If any one of these components fail to perform, there are a few repair tips that can be followed. In order to view the circuitry inside the CPU, its casing has to be removed.

Motherboard
The entire functioning of the computer depends on this component. The processor chipset, that performs all the logical operations of the PC, is embedded in the motherboard. Ribbon cables, power supply, CPU, and RAM are the things to be checked first on the motherboard. Check if any of the ribbon cables

The graphics card is also known as video card, graphic controller, graphics accelerator or display card. It is a PCB (printed circuit board) that has three major components. These components are video memory, video BIOS, and graphics processing unit.

The graphics card should be changed if it gives a poor performance or if you want more speed options for the computer games. In the first case, you need to verify that it is the reason for the poor performance and not the computer. To do this, use the scan disk or defragmentation options and look for bad sectors on the hard disk. You can also try using other ways to speedup your computer. If they do not work, you can conclude that the lowered performance is due to the faulty working of the card. Once it has been established that the graphics card is responsible for the low speed, you should upgrade it.

Some video cards are integrated in the motherboard and some are externally connected to the computer. Older versions of motherboards used a PCI (peripheral computer Interconnect) slot in order to plug-in the video card. Newer versions of computers use the accelerated graphics port (AGP). The latest version of computers

Liquid cooling systems have been used to cool cars since eons and seemingly, it also happens to be the way to cool your computer. Yes, it is true that computers today are designed to emit less heat, but integrated circuits are integrated circuits; they are bound to radiate heat in generous proportions. The joys of overclocking are way too many to be caged under the restriction of heat generation. Having yawned over air coolers, it is time to move on to a slicker option – that is liquid cooling.

Components of a Liquid Cooling System

The liquid coolant comes first, and a popular option is distilled water. Chemical additives (antifreeze solutions) give it that snazzy color and help lower the temperature of the water, increasing its effectiveness. An interesting variant is liquid nitrogen. With a boiling temperature of -196°C, it beats water in every aspect. But the recommended use of liquid nitrogen is strictly for smaller overclocking sessions. A reservoir is the tank that stores the coolant. You need a pump that helps the liquid to flow smoothly. This pump is available in variations that help you fix it outside the reservoir, or submerge it. The radiator is used to absorb the
