Microprocesador/CPU The processor with the motherboard and RAM is one of the essential

parts for a computer. It is usually a small square of silicon coated with many gold pins that receives instructions, processes them and sends commands. Each processor has predefined instructions as addition, subtraction, multiplication, displacement ... etc. It has a small cache memory, which has very little capacity but is ultra fast. Perhaps you could compare a processor with a factory receives raw material and finished product returns.

Motherboard This component, sometimes disparaged, is as important as the

processor. The motherboard synchronizes the operation of all the parts of a computer, 99% of devices are connected there. If we compare the processor with a factory, the motherboard could compare with the road network surrounding it. It is a component which is manufactured in particular thinking processor family and standards in mind. In fact the first thing we choose to assemble a computer is the motherboard and then go looking if it supports certain devices or standards. For example how many video cards can connect, if you have 2 or 1 network cards, if it supports ECC RAM (special memory for servers) ... etc.

Ram RAM is a buffer that stores data and intermediate instructions. Guarda

such as a Word document while you edit in the Office. It is the second fastest computer memory after the cache. All data stored there are deleted when we turn off the computer unlike for example hard disk. In recent years this report has gone from 256Kb to 16Gb. On servers you can even find 64GB or 128GB DDR3 ECC RAM.

HDD The hard drive is one of the essential components of our computer

system. Generally it is an internal part of any computer, although in recent years it has popularized the external format, basically the technology is the same. The "Hard Drive" performance is much slower than RAM, but has much more capacity. Currently in 2015 you can find easily-6TB 4TB units, the most common and economical is to have 1-2Tb. It is also the component that changes radically technology. Magnetic technology gradually gives way to the "solid" or "chemistry" of the SSD or Solid State Drive disks.

Optical Readers Optical readers were very popular in the past. They are basically

those who read all these DVDs, CDs or BluRay discs. Internet now very developed in many countries is almost obsolete the disk drive. Any information can now be downloaded from the Internet or you can take it on a USB stick.

Graphics Card The video card is the part of your computer that sends the video

signal to your monitor or TV. Virtually alone is a small computer because the board has a processor, RAM, BIOS, power inputs ... etc. They are essential for people looking mostly play or video editing or 3D.

External Parts of a Computer Display Microphone Scanner Keyboard Printer Speakers Mause Cabinet

Display es un dispositivo de salida que, mediante una interfaz, muestra los

resultados del procesamiento de una computadora. El concepto de monitor fue definido por primera vez por Charles Antony Richard Hoare en un artículo del año 1974. 

Microphone Electronic apparatus for capturing sound waves and transform them

into electrical oscillations.

Printer Is a computer peripheral that allows a permanent copy of text or

graphics of documents stored in electronic form, printing paper gloss data on physical media, usually paper or transparencies, using ink or laser technology.

Keyboard or is a peripheral device consisting of a key system, such as a

typewriter, which allows data to a computer or digital device. The keyboards are composed of different types of keys that are alphanumeric and keys, scoring special.

Scanner es un periférico que se utiliza para convertir, mediante el uso de la

luz, imágenes o cualquier otro impreso a formato digital. 

Speakers the speakers are used to listen to sounds from the computer to listen

to music or sounds of errors, etc.

Mause is an input peripheral computer electronic use, generally made of

plastic, used as input or control data. It is used with one of the user's hands and detects its relative movement in two dimensions by the horizontal surface on which it rests, usually reflected by a pointer or arrow on the monitor.

Gabinet The cabinet is the outside of the computer and there are two main

types, tower and desktop. In class tower, there are mini tower, mid tower and full tower which are used for servers. Inside the case are all major devices.
