Visual Literacy - Essay Example Despite the high level of novelty of newly emerging media like Youtube, which first appeared in 2005, it cannot be denied that its characteristics still follow the pattern of older forms of motion picture technology. Media, indeed was to some extent, merely renewed or reintroduced in familiar forms (Peters as cited in Snelson & Ross, 2009, p. 2). Thus, as the authors assert, online videos found on the Web like those from Youtube, are undeniably part of the ever-changing educational motion picture technologies or in simple terms, Virtual Learning. Virtual learning particularly permeated the education sector mainly through sites and channels such as Youtube â„ ¢ EDU, a central hub for videos featuring the collaboration of leading colleges and universities. Moreover, other sites like SciVee--site containing video and audio for a community of scientists--and Teachertube--designed for K12 students--exist to specially cater academic institutions. In the midst of these arising motion picture technologies in the academe, the authors found it useful to demonstrate how such technologies aid in the learning process of users. Firstly, motion picture technologies provided teachers a ‘dynamic representational format’ that enabled them to bring the world closer to their students. As Thomas Edison (as cited in Snelson & Ross, 2009, p. 4) puts it, it is similar to taking the object before the student or taking the student to the object. Second, it sparks excitement among students in the classroom setting, bridging the gap of abstract ideas to reality (Amsden as cited in Snelson & Ross, 2009, p. 5). Thirdly, since videos have the ability to capture and preserve the past, they become the key archives of significant historical events. Next, as the Association for Educational Communications and Technology (as cited in Snelson & Ross, 2009, p. 6) puts it, film captures what are considered to be too slow or too fast to be caught by the human eye. Fifth, with the

Government Should Regulate Internet Content Essay

Government Should Regulate Internet Content - Essay Example In that same second 372 internet users are typing adult search terms into search engines. Every 39 minutes a new pornographic video is being created in the U.S. (Ropelato). These videos contaminate the thoughts of young children. They gain access to adult material before understanding the gravity of such things. As a result of this, they take extreme steps. In the days when there was no internet, children did not have â€Å"easy access† to porn. They had to purchase adult material from movie shops which not only cost them a lot, but they also were at the risk of being caught by parents, siblings, friends or peers while purchasing such movies. Watching them on the VCR was also no less risky. In those days, it was not possible to shift the TV from one place to another. In every house, there used to be a specific place for TV. Such place usually used to be in the TV lounge where everybody would frequently come, sit and go. Children had had a tough time managing to watch the movie when somebody would get into the room from anywhere anytime. These factors potentially discouraged children from watching porn at home, and many would spare the idea of watching such movies given the enormity of risks associated with this practice. With the evolution of internet, porn is just at a distance of the click on the mouse. Children’s frequent, quick and easy access to porn has retrograded the society on the grounds of morality. Children’s access to porn not only makes them morally weak, but is also very bad for their psychological and physical health. Children become habitual to committing crime in isolation. The negative energies that cultivate in them gradually show up in their daily dealing and interaction with others. In order to regulate the frustration, adolescents tend to build physical relationships with others before marriage. Many do not have access to members of the opposite gender for such relationships, and hence may resort to homosexuality to f ulfill their physical needs. Porn arouses dangerously violent and wild desires in the children even before they become mature enough to handle such feelings. Consequently, many children land themselves in troubles which keep bugging them throughout their life. It is not just porn that is very deleterious to the moral health of the society, internet provides users with access to information that they can use to have a negative influence on the society. There are videos that teach how to make a bomb. Having seen these videos, an individual can make a bomb at home with the materials locally available with least expenses. As a result of this, they are bale to possess bomb illegally, and may use them for their individualistic purposes against any agency, sect or community in the society. â€Å"†¦those who trade in child porn or bombmaking recipes don't do so in the public domain but swap their information on obscure message boards or by way of peer-to-peer file-sharing sites† (Heacock). Firewall is considered to be a strong shield for network security. Firewall essentially functions like a packet filter that studies various IP packets and after thorough examination, lets only this IP packets pass that conform to the particular criteria of destination, support the specific applications and also run particular transport protocols (Messerschmitt 2). There is no best firewall that can provide a network with ultimate security. In fact, absolute access and absolute security are two extremes. A machine can be
