3. 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.
4. 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.
5. 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.
6. 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.
7. 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.
8. 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.
9. External Parts of a Computer
Display
Microphone
Scanner
Keyboard
Printer
Speakers
Mause
Cabinet
10. 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.
12. 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.
13. 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.
14. Scanner
es un periférico que se utiliza para convertir, mediante el uso de la luz,
imágenes o cualquier otro impreso a formato digital.
15. Speakers
the speakers are used to listen to sounds from the computer to listen to music
or sounds of errors, etc.
16. 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.
17. 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.
