AC

Alternating current is the kind of power that characterizes the magnitude and direction exhibit a cyclical variation. Meanwhile, the manner in which this type of oscillating current is sinusoidal, that is, a curve that rises and falls continuously. Thanks to this form of oscillation of the AC power transmission achieved more efficiently. Alternating current is the kind of power that characterizes the magnitude and direction exhibit a cyclical variation. Meanwhile, the manner in which this type of oscillating current is sinusoidal, that is, a curve that rises and falls continuously.

This type of energy is produced by the generators and is generated in power plants. The current used in homes is alternating current (sockets).


DC

Direct current is the result of the flow of electrons (negative charge) by a conductor (copper wire cable or almost always) What is the negative terminal to the positive terminal of the battery. The DC batteries and dynamos occurs. And it is my time management.

THE MULTIMETER

The multimeter is a measuring instrument used in the electric field to measure the voltage (ie direct or alternating electric current) as well as also the resistance for a given conductor when electrons pass through the.


In computing helps us to know if the power supply of the PC is working well or else a diode or capacitor is shorted.

POWER CABLE




It is the cable is hooked wing source energy and powers the torrefuente and wer empowers tower.

POWER SUPPLY


It is a device that converts alternating voltage supply network in one or more strains, substantially continuous feeding the various circuits of the electronic device to which it is connected (computer, TV, printer, router, etc.).

AT
motherboard. The remaining two types, of which there is a variable quantity, feed the peripherals are not plugged into a slot on the motherboard, such as hard drives, CD-ROM, floppy, etc







ATX
It is very similar to the AT, but has a number of differences, both in performance and in the voltages supplied to the motherboard. The ATX power actually consists of two parts: a main source, corresponding to the old AT source (with some additions), and an auxiliary.




MINIATX
It is a sourceofgrowthwas able to format motherboard fully developed by VIA Technologies. Although it is a proprietary format origin, its specifications are open. In fact, manufacturers have other products in this format.







WATT




CONNECTORS SOURCE

ATX
An ATX motherboard has a size of 305 mm x 244 mm (12 "x 9.6"). this allows in some cases also fit bozamicroatx ATX motherboards.
another feature of the ATX motherboards are the type of connector to the power supply which is 24 (20 + 4) contacts that allow a unique way to connect and avoid mistakes as to sources at and an additional connector called p4 , 4 contacts. also have a software system shutdown.





MOLEX
Molex is a manufacturer of electronic components, including connectors for electrical cables and optical fibers and other products.
It is commonly referred to as internal Molex connectors on a desktop computer. It is used for peripherals that require more amperage cable provided by the school data such as:
- Hard drives (IDE, SCSI and SATA1)
- Units diskettes (3.5 and 5.25)
- Optical drives (CD, DVD and Blu-Ray)
- Video cards (Geforce Series 5 and 6, Motherboards PCI and AGP)
- Cooling systems (air and liquid)
- Modding Circuits (LEDs, light pipes, etc.)





SATA

Serial ATA or SATA is an interface for data transfer between the motherboard and some storage devices such as hard disk, regrabadores readers and CD / DVD / BR, Solid State Drives or other high performance devices are still being developed. Serial ATA replaces the traditional Parallel ATA or P-ATA. SATA provides higher speeds, better use when multiple units.
