Hardware? Hardware applies to all tangible parts of a computer:

their electrical, electronic, electromechanical and

mechanical, cable, cabinets or boxes, peripherals ofall kinds and any other physical elements involved,in contrast, software is intangible and is calledsoftware.

Hardware Types Hardware components and devices to any of the

above functions, ARE:

Processing: Central Processing Unit or CPU

Storage Memory Input: Input Devices (E) Departure: Peripheral output (S) Input / output: mixed Peripherals (E / S)


4/16

Central Processing Unit The CPU, English acronym for Central Processing

Unit is the key component of the computerresponsible for interpreting and executinginstructions and processing dates. In moderncomputers, the function of the CPU performs oneor more microprocessors. It is known as a CPUmicroprocessor is manufactured as a singleintegrated circuit.

RAM Memory

Random Access Memory. The term is related to

the presenting feature access times equal to anyof their positions (either for reading or writing).This feature is also known as "direct access" asopposed to sequential access.


6/16

Dynamic RAM Presentation is more common in modern computers (desktops,

servers) are printed circuit boards with memory chips soldiers byone or both sides, plus other elements such as resistors andcapacitors. This card has a series of metal contacts (with a goldcoating) that allows electrical connection to the memory busmemory controller on the motherboard.

Among the latest technologies for embedded DRAM memorymodules used in the RAM are:

SDR SDRAM DDR SDRAM

SDRAM DDR2 SDRAM DDR3 The standards currently used are: DIMM SO-DIMM


7/16

Special RAM There RAM with features that make them individuals,

and not normally used as computer main memory,among them we can mention:

SRAM: Short for Static Random Access Memory. It is atype of memory faster than DRAM (Dynamic RAM).

NVRAM: Abbreviation for Non-Volatile Random Access Memory. Nonvolatile RAM (keeps the

information in the absence of power). VRAM: Abbreviation for Video Random Access

Memory. A type of RAM that is used in computergraphics cards.

Peripherals Means units or peripheral devices that allow the

computer to communicate with the outside, thatis, both income and externalizing dates.Information and peripherals are operations thatallow known as input / output (I / S ) .


9/16

Devices of input (E) In this category are those that allow the entry of

information in general from some external sourceor by the user. Input devices provide the primarymeans to transfer to the computer (more properlyto the processor) information from any source,either locally or remotely.


10/16

Information output devices (S) Are those that allow broadcast or output the

information resulting from the operationsperformed by the CPU (processing).

Output devices provide the primary means toexternalize and communicate information andprocessed data, either the user or to otherexternal, local or remote.


11/16

Mixed Devices (E / S information) They are devices that can operate both ways: both

input and output. Typically it can be mentioned asperipheral or mixed I / O to: hard drives, floppydisks, magnetic tape, reading and CD / DVD , ZIPdisks, etc.


12/16

Graphics Hardware The graphic hardware is basically what the

graphics card. These components have their ownmemory and processing unit, the latter calledgraphic processing unit (or GPU, English acronymfor Graphics Processing Unit). The basic objectiveof the GPU is to perform the calculationsassociated graphics operations, primarily infloating point, 16 thus freeing the main processor(CPU) of this expensive task (in time) so that itcan perform other functions more efficiently.


13/16

Conclusions: All devices that interact in a case have an important role for

us to receive information on a screen. Although most people do not know some computer terms,

they come to understand what the goal of having a PC at

home. We believe that the majority of young people seeking a PC

with special feature, such as having a high resolutiongraphics for games, that is quick and other features. That's why you must know some hardware to not be surprisedwhen buying.

Worldwide, there are many companies using pc andtherefore require professionals who know about it, butmost of all to master the language and mainly handleproducts that language is English.
