Hardware

Applies to all natural 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. 

FEATURES

Mostly the PCs, are characterized by such physical elements:

1. Monitor
2. Motherboard
3. CPU
4. RAM
5. Expansion Card
6. Power Supply
7. Optical disc
8. Hard disc
9. Keyboard
10. Mouse
11. Printer

Monitor: The monitor on personal computers (PCs) as output device used to display the data entered into the computer, such as documents and their characters, videos, photos and more. These have evolved from the monitor CRT (cathode ray tube), LCD (Liquid Crystal Display), LED and touch.

Motherboard: It is an electronic board where all the components of a PC are connected, when assembling a computer such as RAM, Optical Drive, keyboard, mouse, sound, screen and others.

CPU: It is the central unit responsible for command of the entire system of the computer, functions as the brain of the computer, and controls the operation of the main components such as memory and the ability to perform mathematical operations.

RAM: Called Random Access Memory, is so called because by giving instruction the system searches the data you need regardless of the information.







                                                      

Hard disc: It is the permanent storage drive on computers, they handle great capacity to collect data necessary for the operation of the PC, as well as files, photos and videos etc.  Over time hard drives have increased the speed of 5Mb to portable disks Terabytes. A PC can have multiple drives with different capacities.

Keyboard: Allows typing letters, numbers, symbols and characters that are displayed in the place where the cursor appears, the system normally used for all keypads is the QWERTY, which has been used since typewriters.

Mouse: The shape of these devices allows you to move a pointer around the screen and point to specific objects or characters. This element like keyboard allows user interaction with the data, and these have evolved from the Trackball, optical and lately are being replaced by touch screens.

Printer: It is one of the peripheral printer that produces text and graphics stored in the PC, issuing them on paper using ink or laser technology.







The hardware is divided into input devices and output devices, then the distribution of computer components, according to the above criteria is shown.
