fort into something physical, palpable in technology,

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. "

Through Intenza codigografia and

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

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

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
