science in history.

a myriad of applications sometimes a bit oc-

Dreams, fantasies and reality are the precur-
sors of a world that is projected right
through distant dreams, which are increasin-
gly closer thanks to the passion. "Man on the
moon Impossible", "Flying Man Can not",
"The Round Earth're crazy. "
Who would think that we have in our pockets a
cell phone, so the mix of technology, full of
science fiction that in the not too distant inven-
tions were just for super spies, miniature cameras,
recording conversations, calling someone across
the world.
Although the weather is not kind to the scientists, all
achievements are dedicated to our children and a future
that will see spending what for us is impossible today
commonplace. is envy with scientists about the future.
"much to do and not to do so"
It was not always so ... scientists were di-
rected to an "elite" which did not allow a
closer contact to their knowledge and
achievements. so much so that many will
continue in secret achievements of those
who conoscan and know its potential.
So begins the era of "computing. "

us to practically touch the information.
The first computers were managed by
skilled and knowledgeable workers in
the materia.aun that time, any person
became a team and is a carrier of years
of research and development if some-

by this new generational change. that informa-

Today, connoisseurs know they can
not do something better about a com-

We know they departed for years but
the boom of technology and magic to
be able to access it somehow morbid,
is present today more than ever, and
submitting in a thousand directions.
Thanks to brilliant minds who had a
dream at some point now we can all
play a little for the future with our
hands
Competition has been crucial in the de-

of their labor.
We say that "One hand washes the

based technology to manufacture a
rocket, allowed us know tecniologia

we know it. both socially and in every sphere,
political, scientific and the innumerable exist-

How far we get? which is our limit.
that we say it is good or bad if you and
our dreams come true.

Operating Systems
What is an Operating System?
Definition 1: An operating system (OS) is the program or set of programs which provide the ba-
sic management processes of a computer system, and allows the normal execution of other opera-
tions.
Definition 2: Operating System (OS) is the basic software of a computer that provides an interfa-
ce between the other computer programs, hardware devices and the user.
The basic functions of the OS are managing machine resources, coordinate the hardware and
organize files and directories on storage devices.
The most widely used operating systems are DOS, Windows, Linux and Mac OS Some come
with an integrated browser, such as Windows that brings the Internet Explorer browser.
Comparison between Linux graphical interfaces, Window and Mac
What are the advantages of Linux vs. Windows?, How do they differ?
Installation:
In Linux, despite all efforts, the installation is not always easy, but lets you fully customize
the software packages you install.
Windows installation is minimally configured but is very simple.
Compatibility: Neither of the two operating systems are fully compatible with the hardware,
although Windows is closer, the two are close to doing.
Although Linux is not behind any business house with its high popularity offering high com-
patibility also offering frequent updates.
Windows to be part of Microsoft intends to offer a lot of drivers and their great economic
power that makes the same hardware companies to create their own drivers.
Software:
Linux software to be less in some areas suffer from a lower acceptance by businesses, but
thanks to the support of companies like Sun Microsystems or IBM has made much progress.
Windows to be the easiest to use in business, has a lot of software.
Robustness:
Linux has always been characterized by the robustness of their system and that can take
months or even years without shutting down or restarting the computer, even if an application
crashes just does not totally block the team.
In Windows always have to reboot when you change the configuration, lock easily when
you run seemingly simple operations so you must restart the computer.
Conclusion: Both Windows and Linux have their advantages and disadvantages, but from a
technical point of view Linux wins.
Reasons for change:
It is free software, which means you do not have to pay anything for the system itself.
It is a highly reliable operating system that inherits the robustness of UNIX.
Ideal for networks it was designed on the Internet and Internet
It is true that few programs have only in a very specific field.
It is 100% configurable.
This is the most secure because the source code available anyone can see how much of a
fault, we can say that tens of thousands of people look after your safety.
There is a lot of documentation, also in Spanish through projects such as LUCAS.
Has the support of many large companies like IBM, Corel, Lotus, Siemens, Motorola, Sun,
etc.
You can find help in millions of Internet sites such as forums.
It is very portable, if you have a Mac or a Sparc Alpha can use Linux without problems.
Wireless Fidelity. Data transmission technology using radio waves. Is intended to operate in wireless local area
networks (WLAN). The main advantage of this technology is that data travels wirelessly and can be perfectly
encoded by a 128-bit algorithm
Bluetooth is an industrial specification for Wireless Personal Area Networks (WPANs) that allows voice and data betwe-
en devices via a radio link in the ISM band of 2.4 GHz main objectives to be achieved with this standard:
1) Facilitate communications between mobile and fixed.
2) Remove cables and connectors between them.
3) Offer the possibility of creating small wireless networks and facilitate the synchronization of data between personal
computers.
What is a computer virus?
A computer virus is malware that seeks to alter the normal operation of your com-
puter without permission or knowledge of the user. The virus usually replace other
executable files infected with this code. Viruses can destroy, intentionally, the data
stored on a computer, although other more harmless, which is only characterized
by being annoying.
Computer viruses are basically spread function through software, not replicate
themselves because they have that power [citation needed] as the worm, are poiso-
nous and some also contain a payload (payload) with different objectives, from a
simple prank to do serious damage to systems or computer-generated block use-
less traffic.
The operation of a computer virus is conceptually simple. It runs a program that is
infected, in most cases, due to ignorance of the user. The virus code is resident
(stay) in the RAM of the computer, even when the program containing it has finis-
hed running. The virus then takes control of basic operating system, infecting so
later, executable files that are called for execution. Finally, add the code of the vi-
rus infected program is recorded on the disc, which replicated the process is com-
plete.
Viruses and imitations
There are different types of viruses, vary according to function or how it runs on
our computer by altering the activity of the same, the most common are:
Trojan: Consists steal or alter the system's hardware or in extreme cases allows an
external user can control the computer.
Worm: It has the ability to replicate itself. The worm uses the automatic parts of an
operating system that are generally invisible to the user.
Logic or time bombs: These are programs that are activated when a particular
event occurs. The condition is usually a date (time bomb), a key combination, or
certain technical conditions (Logicbombs). If no status remains hidden from the
user.
Hoax: The hoaxes are not viruses or are able to reproduce themselves. Content
messages are false they prompt the user to make copies and send to your contacts.
Often appeal to moral sentiments ("Help a child suffering from cancer ") or the spi-
rit of solidarity ("Notice of a new dangerous virus") and in any case, try to take ad-
vantage of the inexperience of novice Internet users .
Joke: As the hoaxes are not viruses, but are annoying, an example, a porn site that
moves from side to side, and if it falls short of making a mistake is possible to have
