THE TERM HARDWARE REFERS TO ALL PHYSICAL
PARTS OF A COMPUTER SYSTEM; ITS COMPONENTS
ARE: ELECTRICAL, ELECTRONIC ,
ELECTROMECHANICAL AND MECHANICA
The monitor is an output device for the computer on your
screen showing the results of operations performed on it.
The monitor is commonly known as computer screen and is a
peripheral that connects to the computer to display the
actions and processes running . In that sense, it is key for use
both as a keyboard or mouse.
a keyboard is a peripheral input or device , 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. After the punch cards and paper tape , interaction
via teleprinter -style keyboards to became the primary means of
input for computers. The keyboard has keys 99 to about 147 , and is
divided into four blocks
It is the utilization pointer device to facilitate handling of a graphical
environment on a computer. Usually it made of plastic , and use with a
hand . Relative motion is detected in two dimensions on the flat surface
on which it rests , usually a through a pointer or arrow on the monitor it
reflects . The mouse can be connected cable PS / 2, USB or wireless
The central processing unit , is the hardware inside a
computer or other programmable devices, which interprets
instructions of a computer program by performing basic
arithmetic, logical, and input / output system
La RAM es la memoria utilizada en una computadora para el
almacenamiento transitorio y de trabajo (no masivo). En la RAM se
almacena temporalmente la información, datos y programas que
la Unidad de Procesamiento (CPU) lee, procesa y ejecuta. La
memoria RAM es conocida como Memoria principal de la
computadora, también como "Central o de Trabajo"
In computing, the hard disk or hard drive is the data storage device
that uses 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 situated . It is nonvolatile memory
A motherboard is the main or primary circuit board of a
computer system or other complex electronic system . A typical
computer With the microprocessor , main memory , and other
essential components on the motherboard . Other computer
components
The processor is the brain of the system , responsible
for processing all the information . Basically , it is the
"brain" of the computer. Virtually everything goes
through him, since he is responsible for executing all
existing instructions . The faster your processor , the
faster will be executed instructions
when you are speaking of power supply ( or sometimes , power
supply and power supply ) , referring to the system that provides
the necessary electricity to power equipment like computers or
computers. Generally, desktop PCs , the aforementioned source
of power is located in the rear of the cabinet and is
complemented by a fan that prevents the device from
overheating
A CD- ROM is an optical disc technology that is used
to store and use information on computer media
It is known as the logical equipment or software computer
software system of the United Nations , comprising all the
necessary software components that enable specific tasks
, as opposed to the physical components that hardware
son Called
Mechanism that controls access from programs or users to the
system resources . The OS is responsible for: Distinguish between
authorized and unauthorized use. Specify security checks
performed. Force the use of these protective mechanisms .
To maintain communications with other systems needed to
control the sending and receiving information through the
network interfaces . We must also create and maintain
communication points to serve applications to send and receive
information, and create and maintain virtual connections
between applications that are running locally and others that do
remotely.
They are useful applications that ship with the OS but not part
of it. They provide a useful environment for developing and
implementing programs , and some of the tasks they perform :
Manipulation and modification of files.
System status information .
Support programming languages.
Communications
