Information Technology and Communication (ICT)

Information Technology and Communication (ICT)Currently the Information Technology and Communication ICT are undergoing rapid development, this is affecting virtually all areas of our society, and education is no exception.

This work is of interest that the ICT-Education interaction has aroused worldwide. Education International conference “Education for All for Learning to Live Together (CIE, 2001) held in Geneva in 2001 expressed in relation to Information Technology and Communication (ICT).

These technologies are increasingly a necessity in the context of society where rapid change, increased knowledge and the demands of a high standard of education constantly updated become a permanent requirement.

The relationship between ICTs and education is twofold: On one hand, citizens are forced to meet and learn about ICT. Furthermore, ICT can be applied to the educational process.

This dual aspect is reflected in two different educational expectations: on the one hand, we have computer scientists interested in learning computers, and in the other, teachers interested in using information technology to education.

New Technologies Information and Communication

New Technologies Information and CommunicationSupport information

1 What is information medium?

2 Which means that the media have a way of sequential or random access to information?
3 How we rank them according to the technology used in your configuration?
4) Make a list of at least 8 media find an image of each show its capacity for data storage and gives some general characteristics.
5) Find some images that show how to perform reading and writing data on magnetic media, in an electronic and an optical.

1 – With the constant evolution of computers in recent years, it is necessary that the information already developed by the computer to be memorized or stored in large capacity drives. These units are known as mass storage and are internal or external devices to the computer for storing large volumes of information, both programs and data.
These devices have a fundamental characteristic: the recorded information characters are not volatile, that remains even if power is disconnected.
The stored information will be treated later by another computer with similar characteristics to that was the source of information.

2-Sequential access: sequential access, the reading element of the device must pass through the space occupied by the totality of the data previously occupied space physically stored data comprising the set of information to be accessed.
Random access: the random access mode, the scan element can directly go to the address where the information is stored physically to be located without having to pass through to the stored between the start of the recording surface and the point where stores the information sought.

3-in computer keyboard is an input peripherals or devices, in part inspired by the keyboard of typewriters, which uses an arrangement of buttons or keys, to act as mechanical levers or electronic switches that send information to the computer. After the punch cards and paper tapes, the interaction through the ticker-style keyboards became the primary means for computer input.

4 – The characteristics that must be taken into account on a hard drive are:
* Access Time: Average time it takes the needle on the track and placed in the desired sector, is the sum of average seeks time (on the track), while read / write and the average latency (seen in the sector).
* Average Seek Time: Average time it takes for the needle placed in the desired track is half the time taken for the needle to go from the track more peripheral to more central disk.
* Time read / write: Average time it takes for the disk to read or write new information, the time depends on the amount of information you want to read or write, the block size, the number of heads, lap time and the number of sectors per track.
* Average Latency: Average time it takes for the needle placed in the desired sector, is half the time spent on a full disk rotation.
* Speed: revolutions per minute of the dishes. The higher the speed of rotation, lower average latency.

Information Technology and Communication: Social and Educational Implications

Information Technology and Communication: Social and Educational ImplicationsThe information technology and communication are a part of the emerging technologies that usually tend to identify with the acronym ICT and refer to the use of computerized systems to store, process and disseminate any information or educational training process.
Over the years, ICTs have evolved to meet human needs and highlighting the television and radio.
Societies today are characterized by diverse and abundant flow of information and communication. In a century we have gone from radio equipment that allowed us to hear voices of remote environments, the black and white film, color, special effects and computer-created characters, of the nearly first TV images showed the landing a man on the immediacy of news and images of world events.
ICTs are mainly characterized by their intangibility (possibility of scanning), immediacy and multimedia applications. They have brought great benefits especially in education but in turn if not given proper use, will find disadvantages.

 Educational ImplicationsTherefore, currently the use of information technologies and communication in adolescents is a matter of concern, debate and reflection for many authors, both nationally and internationally. But this concern has not yet been translated into a systematic and organized effort to implement relevant activities for the appropriate use of technology by teens.
For example, one of the major concerns for both educators and the family, about the relationships of adolescents with ICT, is the possibility that appear addictive behaviors that can disrupt personal and social development in the adolescents. The media are the first to emphasize these cases, although there can not be generalized.
You could say that what defines the addictive behavior is the frequency with which this is done; it is the loss of control of the person, and the establishment of a relationship of dependency.
In this regard, seven have been proposed to detect signs of Internet addiction:

* Spending several hours’ online, neglecting important aspects of your life.
* Friends and relatives think you have problems with using the Internet.
* Being young (the younger, more risk must be dependent on the Internet.)
* The use of the Internet creates serious negative consequences.
* You see his reliance on the Internet as a shy, intense activity.
* Keep secret the time you spend online.
* You can not go a day without the computer without connecting to the Internet.

In turn, indicates that this addiction leads to truancy and certain behaviors such as not complying with the schedules chat at all hours and allow interacting with their peers. This addiction is defined as follows: “Cell phone use becomes an addiction when it becomes a repetitive behavior that is pleasurable and creates a loss of control in the subject”

 Educational ImplicationsA related aspect of addiction is isolation. Often, the media reported about this effect, produced the use of ICT, particularly in adolescents. We deliver the image of the young alone, locked in his room and escaping from any social commitment to sit for many hours and connect to your computer. Isolation is a risk that reflects the degree of dependence that has every teenager.

On the other hand, the adolescent population and its environment may be affected because of the potential offered by ICT to get lots of information about its users, without being aware of it. The strategies are many: an apparently inoffensive forms or promotions via SMS to mobile are among the most common. Companies are able to easily pass the barrier between public and private, using the ingenuity of users.
Regarding the second problem, the advertising is not specifically distinct from other information in the contents that we deliver ICT. In this respect it is logical that if we study the composition of such web sites of brands and favorite products of adolescents, and advertising that reaches them through mobile phone, it is difficult to clearly differentiate between information and persuasion.
In addition, through the use of ICTs expand the social relations, but also get new features, which do not exist in the real level of interpersonal communication (face to face). In this regard, the influence of anonymity between the participants has been one of the most studied in relation to the personal identity of adolescents constructed in virtual environments.

Finally, there is talk that the issue of violence has been continually involved in video games. The observed high rate of violence in games has been severely criticized. Much of the publicity of these games is based on the violent aspect, noting that social learning theory posits the hypothesis that aggressive play games encourage aggressive behavior. For example, the children imitate or otherwise learn what they see on the screen.

Increased access to ICTs is a necessary but not sufficient to generate economic development in the region

Increased access to ICTs is a necessary but not sufficient to generate economic development in the regionIn addition to acquiring and expanding access to information and communication technologies (ICTs), countries should assess and strengthen their ability to use these tools, according to a new study by the Inter-American Development Bank (IDB).

Latin America and the Caribbean should improve the skills of its population, physical infrastructure and its institutions and its regulations, so that ICT can have a positive impact on development, the study concluded.

“With appropriate policies, governments can take full advantage of ICT tools to promote development. These technologies can improve the dissemination of information and help solve market failures, “said Alberto Chong, chief economist of the IDB and the study coordinator.”But it is important to note that, by itself, increased access to ICTs will not cause development. Countries should also focus on how to apply these tools. “

The book Connections development: the impact of new information technologies examines how ICTs have contributed to the success of 46 development projects in Latin America and the Caribbean in six areas: finance, health, institutions, education, poverty and environment. This study is the first in the region systematically applying rigorous statistical methods to measure how information and communication technologies had an impact on the results of the projects.

Based on randomized control trials and economic studies, researchers found that 39 percent of the reviewed projects benefited greatly from the adoption of new technologies, while others only partially or minimally benefited from the application of ICT.
