2. HARDWARE It corresponds to all physical and tangible parts of a computer: your electrical, electronic, electromechanical and mechanical components; cables, cabinets or boxes, peripherals of all kinds and any other physical element involved

3. MONITOR is the primary output device (interface), showing data or information to the user.

4. MOTHERBOARD It is fundamental to build any PC desktop or laptop part. Has installed a series of integrated circuits, including integrated auxiliary (chipset) circuit, which serves as a hub between the microprocessor (CPU), random access memory (RAM), expansion slots and other devices is.

5. RAM In RAM all instructions running the central processing unit (CPU) and other computer units are loaded. They are called "random access" because you can read or write to a memory location with a timeout same for any position, not necessary to follow an order to access (sequential access) to information as quickly as possible.

6. POWER SOURCE It is the device that converts alternating current (AC), in one or more continuous current (CC), which feed the various circuits of the electronic device to which it is connected (computer, TV, printer, router, etc.).

7. OPTICAL DISK is a disk drive that uses laser light or near electromagnetic waves the spectrum of light as part of the process of reading or writing of data from a file to optical discs through light beams interpret refractions caused on his own issue.

8. HARD DRIVE It is the data storage device employing a magnetic recording system for storing digital data. It consists of one or more plates or hard drives, united by a common shaft rotating at high speed inside a sealed metal box. On each plate, and on each of its faces, a head read / write floating on air foil generated by disc rotation is located.

9. EXPANSIÓN CARD is a device with various integrated circuits and controllers, which inserted in its expansion slot is used to expand the capabilities of the computer. The most common expansion cards used to add memory, disk drive controllers, video controllers, serial and parallel ports or internal modem device.
