What's inside your PC?
First there is the main
processing unit or CPU, it usually includes the keyboard, mouse, memory or
RAM, hard disk, dvd drive, monitor to make a functional unit.
A PC can
be purchased as a complete system with the Central Processing Unit,
keyboard, mouse, memory, hard disk, dvd drive, monitor and other
components, or each component can be bought separately.
Online
or walk-in stores are great places to purchase a personal computer for
home or business use.
A look at some of the basic PC components:
The keyboard is an important component for a
computer system. Users need a device such as a keyboard to enter your
words and commands for the computer. It is a input device that is used use
to answer questions from a website while ordering an item, creating an
article or essay, to enter registration information to a new website.
Each key represents an alphabet, number, function, spacebar, alt,
ctrl, and action keys like Insert, Delete, Home, Page Up, Page Down, Home,
End, arrows and other keys. Each time you type a key on the keyboard, it
sends a signal through the circuit underneath called Key Matrix Circuit to
the computer.
The connection from a keyboard to the computer is
accomplished with a cable to a PS/2 or Unversal Serial Bus connection.
Another major component is the mouse, which is mostly used for
clicking a button, checkbox, option box, or to navigate around the screen
on the monitor. It is very useful if you are drawing on the screen, like
painting a picture or drawing a flowchart.
There are several types of
mice. Included are the ball mouse, optical mouse, and laser mouse types. A
ball mouse is a mouse with a round ball under the casing, moving the mouse
on a mouse pad will rotate the ball and then send the signal to the
computer for the navigation. An optical or laser mouse both use optical to
send signal to the computer, the difference is an optical mouse uses
light-emitting diode or photo diode to detect the movement, while laser
mouse uses infrared laser diode to sense the motions.
Diodes are an
electronics component that generally emits light. The connection from a
keyboard to the computer is achieved with a cable to the RS-232C, PS/2 or
USB connection on the computer. Memory components such as Random-Access
memory or RAM or hard disk are essential for the computer storages. RAM is
basically used for temporary storage of data, and the data will be erased
after exiting a software, rebooting or turning off the computer. The
larger size the RAM, the higher performance and faster the computer will
work, because the computer can do most of the work on it without copy data
back and forth from the hard disk.
Hard disk is a
permanent storage device for the computer, saved data will stay there
until they are erased. Again, the higher the access and rotation speed of
the hard disk will improve the overall performance for the computer
system. DVD or Digital Video Disc drive is another component that is
important for you to install software or store data to a cd or dvd disk.
