Our personal computers or PCs are tools for work and leisure use with fairly comprehensive.
PCs are powerful creations that sometimes seem to have a life.
Usually respond to a command
typed on the command line or a mouse vaulting, performing tasks that we believed to be unable to perform
without some kind of help.
But even obeying our commands, sometimes it becomes difficult to suppress
feeling that something magical happens on your computer.
And there are times when our PC rebels and arrives at the gates of chaos cluttering our beautiful
column of numbers, our sentences clearly drawn and charts carefully handled.
When this happens, we
pretty sure that even though we are playing with power, we can not control it completely.
We become
learners, where each attempt hit leads to improvement
No matter if our computers are faithful servants or not, what matters is that we begin to realize that there is more
things happening within those colored boxes than we can comprehend.
PCs have secrets.
Open these boxes well
protected and you will see components never imagined.
Some of them seem to give clues of what they do.
Most are
microchips enigmatic whose only information we provide is the secret code printed on their surfaces impenetrable.
The maze of circuitry that runs the plates is fascinating but obscure, like hieroglyphics.
Some parts
important as the hard drive and power supply are sealed with recommendations printed on the dangers of
violation.
This site is not a do-it-yourself.
Do not see the illustrations as looking unscrew this part
or that.
But as a way to better understand what is going on inside all of these components, which are
to be less formidable when something really goes wrong.
This site is dedicated to the knowledge of how a computer works and a bit of computer history and evolution of computers.
In our opinion the knowledge in itself is worth it and is a very worthwhile objective, enjoyable.
This content was written to try
answer several questions about what actually happens inside the computer case which you spend hours on end
sitting in front.
If you can solve your doubts or awaken others, the effort was worth it.
At the same time, however, I believe that know the secrets behind this trick will not spoil the show.
That
is the danger.
The mystery is so much knowledge booster.
I'd hate to think that something you have read on this content
can get that happy feeling you get when running our PC can do a new trick, something
really fascinating.
Instead, I hope the contents make it into a mage even more confident.
This content
was written with a certain type of computer in mind, a computer is a bit
old, but it illustrates the principles of operation of modern computers
in general.
We use the IBM PC, equipped with microprocessor
Intel and the operating system running on MS-DOS.
Many of the explanations contained in the content refers only
this type of computer and its
components, but understand that computer helps a lot to understand the
more modern computers and appreciate the evolution of computers.
In more general terms, the explanations may apply to Macintosh computers, to Unix workstations and even mini-computers
and mainframes.
But do not intend here to discuss universal explanations of how computers work.
To
reach that level, we would necessarily untangle and inspect very specific components.
Even so, there is so much variety in the world of PCs IBM / Intel / MS-DOS that sometimes had to limit my explanations
specific settings or limit the boundaries of a particular situation to make the explanation more general
possible.
If you find something that does not seem to be correct in this content, hopefully the only question is my
limitations regarding the generalization of explanations.
