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.

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.

MAINBOARD

The motherboard is a printed circuit board that allows the integration of all components of a computer. For this, has a basic software known as BIOS, enabling it to fulfill its functions.

PORTS USB, PS / 2, Ethernet (RJ45). SERIAL, PARALLEL, SOUND, SATA EXTERNAL.

USB PORT

It's basically a rectangular 4-pin connector that allow transmission of data between a wide range of external devices (peripherals) with the computer; therefore is considered port.

PS/2

Connector type is usually used to connect the keyboard and mouse on PC. Currently many computers, especially laptops, do not bring more than the PS / 2 port, as many mice and keyboards come to the USB port.

SERIAL

A serial port or serial port is a communications interface digital data, frequently used by computers and peripherals, where information is transmitted bit by bit sending a single bit at a time, in contrast to the parallel port that sends several bits simultaneously.

 PARALLEL PORT

A parallel port is an interface between a computer and a peripheral, whose main characteristic is that the data bits traveling together, sending a packet byte at a time.

THE AUDIO PORT

The audio port has the function of capturing audio from outside, record audio, play sound to speakers and capture the microphone signal comprises a cylindrical connector with 2 or 3 terminals that allows transmission of data to an external device (peripheral), basically speakers and microphones, from computer.

SATA EXTERNAL

It is called port that enables data transmission between a (peripheral) external device to the computer. It is a port of spatial form with 7 terminals, emerging market, based on technology for SATA hard drives. And is integrated on the motherboard (Motherboard) and also through PCI expansion cards.

SOCKETS

It is a type of electronic socket installed on the motherboard, which is used to fix and connect the microprocessor, without allowing solder be removed later. Therefore, equipment used in open architecture, which seeks to have modularity in the variety of components, allowing the change of the card or integrated.

MULTICORE

Multi-core technology is the term that describes today's processors that have two or more worksheets processor (more commonly known as cores) working simultaneously as a single system. Dual-core or dual-processor chips that function as a single system are the first type of multi-core technology applications.

HYPER READY

Allows prepared to run multithreaded programs (multi-threaded) processing in parallel within a single processor, increasing the use of processor execution units.

RAM MEMORY DDR, DDR2, DDR3.

DDR

Modules are composed of synchronous memories (SDRAM), available in encapsulated DIMM, which allows data transfer for two different channels simultaneously in the same clock cycle.

DDR2

The DDR2 memories have higher latencies than those achieved with conventional DDR, which harmed their performance. Reduce latency in DDR2 is not easy.

DDR3

These modules can transfer data at a rate of 800-1600 MHz Effective Clock, compared to the current range of DDR 2 533-800 MHz or 200-400 MHz DDR.

CONNECTORS SATA, PATA OR IDE

SATA:

It is an interface for data transfer between the motherboard and some storage devices, as can be the hard disk, readers and regrabadores CD / DVD / BR, Drives Solid State or other devices of high performance are still being developed.
