EXTERNAL COMPONENTS

KEYBOARD: a keyboard is an input device or peripheral, partly inspired keyboard typewriters, which uses an arrangement of buttons or keys, to act as mechanical levers or electronic switches that send information to the computer.

MOUSE: It is a pointing device used to facilitate handling of a graphical environment on a computer. It is usually made of plastic, and is used with one hand. Detects relative movement in two dimensions by the flat surface on which it rests, usually reflected by a pointer, or cursor arrow on the monitor.

PRINTER: A printer is a computer peripheral device that enables a continuous range of text or graphics of documents stored in electronic form, printing it on physical media, usually paper, using ink or laser technology

SPEAKER: The speaker is a device used to play audio from an electronic device is also called loud speaker horn, etc. The speakers convert electrical energy into mechanical waves and this becomes acoustic energy

DISPLAY: The monitor is an output device, using an interface that shows the results of a computer prosedimiento. displays the content that is running and the actions taken

INTERNAL COMPONENTS

MOTHERBOARD: The motherboard, also known as a motherboard or motherboard is a printed circuit board to which the components constituting the computer or computer are connected. It is a fundamental part when building a PC desktop or laptop

MICROPROCESSOR: is the center integrated complex circuitry of a computer system; by way of illustration, it is often called by analogy the "brain" of a computer. It is responsible for implementing programs from the operating system to user applications; scheduled runs only in low level language instructions, doing simple things such as add, subtract, multiply, divide, binary logic and memory accesses arithmetic and logical operations.

BIOS: The BIOS is responsible for allowing the operating system boot. For this, analyzes the hardware (for example, checks if the keyboard is connected and Sends an error message otherwise), check memory, among others. This phase is known as POST (Power-On Self-Test).

COOLER: It is a fan that is used in the cabinets of computers and other electronic devices to cool them, usually taking the air are heated from the inside of the device with the colors.

RAM: It is used as working memory computer for the operating system, programs and most of the software. In all instructions RAM running the central processing unit (CPU) and other computer units are loaded.

BUS: For computers, the bus is a series of cables that work loading data in memory to transport them to the Central Processing Unit or CPU. In other words, a data bus is a highway or transmission channel information inside the computer that connects the components of the system with the microprocessor.

POWER SUPPLY: It is referring to the system that provides the necessary electricity to power equipment such as computers or computers. Generally in desktop PCs, the aforementioned source of power is located at the rear of the cabinet and is complemented by a fan that prevents the device from overheating.

MEMORY BANK: formed by one or more "chips" forming the RAM, this is one of the two parts of the main memory. Today's PCs contain a number of sockets where called SIMM (Single Inline Memory Module) modules these in turn formed by several "chips" are inserted; this modular construction allows adding more modules, and therefore more memory when needed in a simple way; that if, respecting placement rules regarding their number and size.

NETWORK CARD: A network card (also called network card or Network Interface Card (NIC)) is a kind of card intended to be introduced into the motherboard of a computer or connected to one of its ports to enable the machine to join a network and can share resources (such as documents, Internet connection or a printer, for example).

SOUND CARD: Among the various hardware devices that are within a team, we highlight the presence of the Sound Card, also known as Sound Board, being not essential for itself, but considered as part of the expansion slots on a team designed, as its name is indicating, to the output or input sounds, or any other information in sound form that is present on the computer.

HARD DRIVE: is a storage device nonvolatile data (because the stored contents are not lost even is not powered) and employing a magnetic recording system for storing digital data.

OPTICAL DRIVES: Optical drives store information by means of microscopic protuberances engraved on its surface and are read by a light beam or laser which is reflected on the disk surface and a sensor determines whether a zero value or recorded .
