COMPUTER PARTS OF EXTERNAL AND INTERNAL.

NATIONAL ACADEMIC.

EXTERNAL PARTSDISPLAY: It is an output device that, using an interface displays the results of processing a computer. The monitor concept was first defined by Charles Anthony Richard Hoare in a 1974 article.

MOUSE: 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.

KEYBOARD: is a peripheral or device that consists of a set of keys, 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.

CPU: Central Processing Unit, this is the most important part because it is the brain of the computer, inside her commanded all tasks are performed by the user, it consists of specific internal parts which will be explained later.

CABINET: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.

SPEAKERS: The speakers are used to listen to sounds from the computer to listen to music or sounds of errors, etc.

MPRESORAS: es un periférico de computadora que permite producir una copia permanente de textos o gráficos de documentos almacenados en formato electrónico, imprimiendo en papel de lustre los datos en medios físicos, normalmente en papel o transparencias, utilizando cartuchos de tinta o tecnología láser. 

BUG: Electronic Instrument designed to capture sound waves and transform them into electrical oscillations.

SCANNER: is a peripheral that is used to convert, by using light, or any other printed images to digital format.

INTERNAL PARTSPOWER SUPPLY: The power supply is extremely important in any computer equipment accessory because it stores the energy of the team and if the power goes out, allows you to save documents and turn off the computer without loss of information.

MICROPROCESSOR: that also will call processor or CPU (Central Processing Unit - Central Processing Unit) is the brain of a computer. This is responsible for taking the information received from different sources, make the necessary processes this information and send the result to the destination directed.

MEMORIES: is where your computer stores programs and data you are using. There are two types of memory: RAM (Random Access Memory). It is composed of one or more chips and used as working memory where you can save or delete our programs and data. And the ROM (Read Only Memory) Consistand in a chip that has taxed a number of programs and essential data for computer operation: boot system, basic hardware control, diagnosis.

HARD DRIVE: is a device non-volatile storage, ie retains information that has been stored correctly even with the loss of energy, it uses a digital magnetic recording is where it is in most cases stored the operating system of the computer.

VIDEO CARD: is an expansion card for a computer, responsible for processing the data from the CPU and turn them into comprehensible information and representable in an output device such as a monitor or TV.

SOUND CARD: is a computer expansion card that allows audio input and output under the control of a computer program called Driver (English Driver).

MOTHERBOARD: (motherboard) is a card where are located the key components of a computer. Contains the microprocessor, memory and other circuits that are essential to the functioning of the PC.

FANS: is a fan that is in the processor that allows cool the components on the motherboard.
