La sociedad del conocimiento

De unos años a esta parte,  nos “bombardean” constantemente con términos que (creemos) hacen referencia a un conjunto de cambios en el ámbito de la educación, el empleo y la tecnología, en los países más industrializados. El término más nombrado últimamente en el ámbito académico y empresarial es el de  ‘Sociedad del Conocimiento’ pero ¿a qué se refieren realmente? ¿cuándo surgen?.
Tiene su origen en los años 1960 cuando se analizaron los cambios en las sociedades industriales y se acuñó la noción de sociedad post-industrial.Cambios en la estructura económica y social, en la que el conocimiento ha substituido al trabajo, a las materias primas y al capital como fuente más importante de la productividad, crecimiento y desigualdades sociales.

El autor más influyente que ha utilizado el concepto de sociedad post-industrial es sin lugar a dudas, el sociólogo Daniel Bell (1973; 2001). Estos análisis apuntaron, por tanto, a una sociedad cientificada, academizada y centrada en los servicios, a diferencia de la sociedad industrial, caracterizada por el conocimiento experimental, el predominio de los sectores industriales, las actividades manuales y el conflicto entre capital y trabajo.

VIdeoPad

Video editing is a process in which a publisher produces a visual or audiovisual work from conveyances as video files, photographs, graphics, and animations. In most cases audio can be music or dialogue between characters is included, but there are issues where the audio is not used and only used visual aids. Usually the video editing is done by computer, along with a program specialized in video editing where the editor manipulates the media with the help of different tools in order to achieve a desired "composition" and get a final result, commonly called "final video "or" final film. "The basic issue is to play the media, "cut them" and order in real time. Although it happens, as in any other style of editing, you can add effects, transitions, filters or texts to enhance or emphasize the video to be created, it all depends on what you want to accomplish.
There are many different editing styles, ranging from amateur home videos which usually are created, the editing vidding style, and even more complex as vj sessions and professional issues within the field of Cinematography.



Types of editing

Digital edition
 Is to manipulate through a video editing program, the various media files like video, photos, graphics or animations, and where it is possible to manipulate audio although usually very simple. Once created our assembly (also called "project" or "composition") is carried out rendering with which the final video (this action is also called "record", "export", get "save "or" create "video, but it is exactly the same). Already obtained the final video, you will be given the intended use or the specific purpose for which it was created, how to produce a movie, show it to an audience, etc..

Today there are several computer programs used for digital edition focused on the different type of publication, from the most basic and MAGIX Video deluxe, Pinnacle Studio, Nero Vision, Windows Movie Maker or OpenShot, Corel VideoStudio Pro X5 and semiprofessional and professionals such as Final Cut Studio, Cinelerra, Adobe Premiere Pro, Sony Vegas Pro, Avid, Dalet Plus, etc..

Analog edition
This type of issue has nothing to do that recorded the signal is digital. To carried out by two recorders, one that is the reader or player (player) and a recorder (recorder) are required. The editing process is to record in the recorder's signal reproduced by the player. The feature that differentiates the two VTRs is red rec button, then this button is only present in the recorder. In the raw tape player (which contains the recorded images from the camera) is inserted into the recorder and the master tape (first tape mounting) is inserted. This can make successive copies will be called second, third ... generation lost with each new copy of picture and sound quality. Note that there are digital video tapes such as the DVC-PRO used in linear editing with multiple copies that can be made without losing image quality since the signal is recorded on a Digital and Analog not. This type of video editing has been losing dominance in the industry, being displaced by non-linear editing, both for its advantages in comfort and manipulating images as lower costs. If however this method was most often used in his time.

Malware

Malware, also called badware , malicious code , malware, or malicious software , is a type of software that aims to infiltrate or damage a computer system or information without the consent of the owner. The term malware is used by computer professionals to mean a variety of software hostile,  intrusive or annoying.The term computer virus is often applied incorrectly to refer to all types of malware, including true viruses.

Software is considered malware based on the effects, designed by the creator, cause a computer. The term malware includes viruses, worms, trojan horses, most rootkits, scareware, spyware, intrusive adware, crimeware and other malicious and unwanted software.

Malware is not the same as defective software; the latter contains dangerous bugs, but not intentionally.

Interim results from Symantec published in 2008 suggested that "the rate at which are circulated malicious code and other unwanted programs may have surpassed that of legitimate applications. According to a report by F-Secure, much malware was produced in 2007 as in the previous 20 years combined.

Hidden malware
For a malware to complete its objectives, it is essential to remain hidden from the user. For example, if an experienced user detects a malicious program, end the process and erase the malware before it could complete its objectives. Concealment can also help get the malware was first installed on the computer.

Some types of hidden malware

Backdoors 
A backdoor is a method to circumvent the usual procedures of authentication when connecting to a computer. Once the system has been compromised (by one of the above methods or otherwise), you can install a back door to allow easier remote access in the future. The rear doors can also be installed prior to malicious software to allow entry of the attackers.


Drive-by Downloads 
Google has found that one in 10 web pages that have been analyzed in depth may contain so-called drive-by downloads, which are sites that install spyware or codes that give information on computers without the user noticing.


Rootkits 

Techniques known as rootkits modify the operating system of a computer to allow the malware to remain hidden from the user. For example, rootkits prevent a malicious process is visible in the list of system processes or that its files are visible in the file browser. Such modifications get hide any indication that the computer is infected by a malware. Originally, a rootkit was a set of tools installed by an attacker on a Unix system where the attacker had gained administrator access (root access). Currently, the term is used more generally to refer to concealment routines in a malicious program.

Trojans
The term Trojan is usually used to designate a malware that allows remote administration of a computer, surreptitiously and without the consent of the owner, by an unauthorized user . This type of malware is a hybrid between a Trojan and backdoor Trojan not considering the definition .

Broadly, the Trojans are malicious programs that are disguised as something innocuous or attraction that invites the user to run a malicious software hiding . That software can have an immediate effect and can lead many undesirable consequences , for example , delete the user's files or installing more undesirable or malicious programs .

The types of trojans are backdoors, banker , botnets, dialers , droppers , downloaders , keylogger , password stealer , proxy.17 18

The Trojans known as droppers19 20 are used to start a worm propagation injecting within the local network of a user.

One of the most common ways to distribute trojans spyware is attached by a desirable software downloaded from the Internet . When the user installs the software expected , the spyware is put also .

We did three works in GIMP. First we did a work moving the layers. We have to put our photos in a place where we like. At the begining it is very difficult, so for this reason we took so many time, but then when you take fluently it is easy. The second work was the Tenorio´s work that was easy because it was similar to the first work. And finally we did a lemon face that was very funny because you could put the face what were you want. This works were helping me to how to use the GIMP.

NETWORKS

A computer network or data network is a telecommunications network that allows computers to exchange data. In computer networks, networked computing devices pass data to each other along data connections. The connections (network links) between nodes are established using either cable media or wireless media. The best-known computer network is the Internet. Network computer devices that originate, route and terminate the data are called network nodes. Nodes can include hosts such as servers and personal computers, as well as networking hardware. Two devices are said to be networked when a device is able to exchange information with another device. Computer networks support applications such as access to the World Wide Web, shared use of application and storage servers, printers, and fax machines, and use of email and instant messaging applications. Computer networks differ in the physical media used to transmit their signals, the communications protocols to organize network traffic, the network's size, topology and organizational intent. The unit of networks is very extence so I´m only going to talk abaut the different types of networks. Types of networks ● Depending on its size or area of ​​coverage: (PAN) (Personal Area Networks): communicating devices within a few meters, for example, a phone with a computer. (LAN) (Local Area Networks): small area, like a home, a school, college or business. (MAN) (Metropolitan Area Networks): for one city. (WAN) (Wide Area Networks): connect equipment between cities, countries or continents.
● Depending on your level of access or privacy: Internet: A worldwide network of computer networks. Have public access. Intranet: A local network that uses Internet tools (web, mail, ftp, ...). It can be considered as a private Internet operating within the same institution. Extranet: A virtual private network, that is part of the Intranet of an organization that extends beyond users.
● According to their functional relationship: Client-Server Clients use the shared resources and services provided by servers: web, data, printing etc.. Networking peer or P2P (Peer to Peer): All devices can act as clients or servers.

Selfie

A selfie is a type of self-portrait photograph, typically taken with a hand-held digital camera or camera phone. Selfies are often associated with social networking. They are often casual, are typically taken either with a camera held at arm's length or in a mirror, and typically include either only the photographer or the photographer and as many people as can be in focus. Selfies taken that involve multiple people are known as "group selfies". History Robert Cornelius, an American pioneer in photography, produced a daguerreotype of himself in 1839 which is also one of the first photographs of a person. Because the process was slow he was able to uncover the lens, run into shot for a minute or more, and then replace the lens cap. He recorded on the back "The first light Picture ever taken. 1839." The debut of the portable Kodak Brownie box camera in 1900 led to photographic self-portraiture becoming a more widespread technique. The method was usually by mirror and stabilizing the camera either on a nearby object or on a tripod while framing via a viewfinder at the top of the box.[4] Russian Grand Duchess Anastasia Nikolaevna at the age of 13 was one of the first teenagers to take her own picture using a mirror to send to a friend in 1914. In the letter that accompanied the photograph, she wrote, "I took this picture of myself looking at the mirror. It was very hard as my hands were trembling." The earliest usage of the word selfie can be traced as far back as 2002. It first appeared in an Australian internet forum (ABC Online) on 2002 September 13. Goodbye 'selfie', now that takes a 'braggie' On the Internet, no run, fly and fashions last as a cigarette in the house of Big Brother. The Oxford Dictionary just choose 'selfie' as word of the year. But in the universe that 2.0 to torpedo your contacts with pictures of your holy presence smiling and pouting starts charging. And there are already parts: the 'braggie' (to brag, boast that means). The term refers to the hobby so fashionable to upload photos to social networks to brag to all your contacts. It may be because you're in the front row of a concert with tickets agotadísimas, just taking a cocktail in a VIP area, the boarding pass to a heavenly or enjoying beach holidays in the Southern Hemisphere while Europe freezes target average cold.
