Desde hace varios años el PC (Personal Computer – Computadora Personal), conocido como ordenador personal o, simplemente, como computadora, se ha convertido para muchas personas en un instrumento indispensable de trabajo e incluso de ocio. |


For several years the PC (Personal Computer - Personal Computer), known as a personalcomputer, or simply as a computer, has become for many an essential tool of work and even leisure.

Todo usuario de un ordenador lógicamente conoce los pasos a seguir para ponerlo en funcionamiento, pero no todos conocen cómo funciona, ni pueden identificar su configuración interna, es decir, las piezas y dispositivos principales que se encuentran alojados en el interior de la carcasa o cubiertametálica de protección.
Every computer user knows the logical steps to make it operational, but not everyone knows how it works, and can identify their internal configuration, ie, parts and devices that are housed inside the casing or cover protective metal.

However, we can say that everyone who works with a computer or personal computer knows what the hardware or peripheral devices more visibleand common form it, such as:
Main Computer
Floppy Disk Drives 3.5 "(virtually unused)
Reader and / or CD or DVD recorder

Sin embargo, podemos decir que todo el que trabaja con un ordenador o computadora personal conoce cuáles son los dispositivos de hardware o periféricos más visibles y comunes que la componen, como son:
Cuerpo del ordenadorDisquetera para disquetes de 3,5 pulgadas (prácticamente en desuso)
Lector y/o grabador de CDs o DVDs


In principle all PCs or personal computers are installed on your motherboard the same devices, but with different characteristics of capacity and speed of data processing, which means they can perform operations more or less rapidly andmore or work permit fewer programs open at the same time.

1) reader and CD burner and dual layer DVDs.

2) Fan Dual-Core processor.

3) Dual Serial ATA hard drive.

4) voltage transformer or voltage.

5) Motherboard.

6) video card.

What happens when we turn on the computer?

Board (mother board), which shows the steps taken toinitialize the computer for operation from time to press the power button.

When we turn on the computer, electrical power (1) reaches the power transformer or power (2). Through the connector (3) the processor distributes the different voltages and operating voltages to the motherboard, including the microprocessor or CPU (4). As soon as the microprocessor is powered, it sends a command to thememory chip ROM BIOS (5) (Basic Input / Output System - Basic Input / Output), which are recorded routines POST (Power-On Self- Test - Self-diagnostic on) or boot program. Without the BIOS contains the set of instructions recorded in memory, the computer system of the computer could not load into RAM from the operating system files required to start the boot and let the rest can be used programsinstalled.

Once the BIOS receives the order of the microprocessor, the POST begins executing a sequence of diagnostic tests to see if the video card (6), RAM (7), disk drives [if you have floppy disk, drive (8), player and / or CD or DVD], keyboard, mouse and other hardware devices connected to the computer are able to function properly.

When the BIOS can not detect a particular deviceinstalled or detect failures in any of them, you will hear sounds in a series of beeps and beeps and displayed on the monitor screen error messages, indicating that there are problems. If the BIOS does not detect anything abnormal during the review, contact the boot sector (boot sector of hard disk) to continue the boot of the computer.

During the previous check, the BIOS is displayed on the...
