 The New communication technology: Mention all new media

communication technology

communication technology The new technologies refer to all the new media that, in recent years, have facilitated the flow of information (internet, digital video disc [DVD], portable computers, and all the technological devices used to produce,

 develop and carry out communication). Concerning the media, new technologies have made possible the existence of digital newspapers, Internet advertising, the broadcast of music and videos without the need for radio or sound equipment, as well as communication instantaneous between people of different countries with an economic cost much lower than that implied by conventional telephone services.

History

Talking about new media means referring to the Internet, electronic media, and all forms of communication derived from these media, which have revolutionized information and communication processes while growing by leaps and bounds throughout the world. Although the history of the new media in Colombia is quite short, its enormous influence has already begun to be felt and understood.

Before they had the enormous impact on the social structure that they have had today and for a few decades, both the Internet and electronic communication took time to develop and mature; However, once they succeeded, and despite the great amount of criticism, it has become evident that these media recover certain aspects of oral societies, such as the simultaneity of action,

 perception, and reaction; They have also made the sensory experience once again an essential form of communication, although in a different way from how it was previously understood, since physical contact between people is no longer needed to feel the body and the sensations of the other: communication electronics does not think about the physical limitations of time or space (an example of this is electronic messages,

Internet

communication technologies It is the interconnection of different computer networks at a global level, all computers that are connected to this world network can connect with any other computer that is also connected. This is why we can easily access the computer networks of companies,

educational institutes, officials, etc. The need to interconnect between different computer networks was born in the United States when the Department of Defense decided to have a communications network that could be operated from different sites in a secure way,

this creation was called ARPA, which connected computers located in different places, although they worked under different operating systems. For this communication to be possible, codes called protocols had to be developed, which were in charge of Vinton Cerf and Robert Kahn who presented their creation in 1973, seeing its functionality, 

this connection ceased to be of strict military use and began to link different educational and research centers. A short time later, networks belonging to European organizations joined, giving rise to the connection called World Wide Web or World Cobweb in 1990. At present this type of connection is not only used for educational or research purposes,

 but it is also an important commercial tool where Any company can present its products or services and in some cases, visitors can access them through online purchases.

The Internet arrived in Colombia in 1993 thanks to the need that the Universidad de Los Andes had to remain connected with other universities in other countries that decided that they would only exchange data over the Internet. This entity assumed the necessary costs to start this type of connection in our country, 

some time later other universities joined the project. Telecom was the telecommunications company that commercially led the coverage of the Internet at the national level, launching it to the general public in 1998, the first Internet connections were made through telephone lines, so in 2001 the same rate was regulated to make it easier to access this communication technology network.

In Colombia, not many people have this and other electronic resources (in 2002, only about 2.6% of the population had access to the Internet), mainly due to economic issues, even even though current education seeks to sensitize students to this new multimedia medium that integrates elements of the media such as radio, video, sound,

text, etc. Nowadays, in Colombia, the use that is made the most of the Internet is that of generating e-mails and that of rapid search of specific information (it is evident that there is a lack of education in this regard, and that the vast majority of people are unaware of the enormous capabilities offered by electronic media).

More and more attractive and better-designed portals proliferate online, shopping sites for all kinds of things that promise to change the lifestyle of today's societies and that seek to make life easier for consumers.

In our country, we are still far from these great changes, because according to theorists such as Jesús Martín Barbero, Latin America is still an area where human contact is necessary. communication technology

 

Satellite antenna

The satellite antenna is a device located on the earth, which is used to receive any type of information sent by a satellite located in space by sending radio frequency signals, no matter how much distance there is between the two.

The first satellites were put into orbit in 1960 and from that date, the satellite antennas installed by the United States government began to be used. The triumph of satellite communication was on July 21, 1969, when 600 million people saw astronaut Neil Armstrong set foot on the Moon, under the control of the Houston station. The Home Box Office (HBO) company was the first to use a satellite network for transmission. communication technology

The first satellite signal seen by Colombians, in 1968, was motivated by the visit of Pope Paul VI to the country, for which the installation of an antenna was requested. This process was led by the only telecommunications company that existed at that time, TELECOM, which was in charge of acquiring two more antennas. Sometime later, the national government approved that other telecommunications companies have the opportunity to manage these resources.

Computer

Contributing to modern scientific advances, the computer is a machine or electronic device capable of receiving instructions for storing and ordering data and computing information at high speeds. The first mechanical calculating machine was invented by Blaise Pascal in 1642 and from then on advances were made that provided more complex machines each time, 

in the 19th century Charles Babbage elaborated the principles of the modern computer. Analog computers began to be built at the beginning of the 20th century and during the Second World War what is considered the first fully electronic digital computer was built. Year after year, 

advances have been made in the computer industry until we have the powerful and inexpensive (taking into account what they do) equipment that we have in our homes. At present, computers are a fundamental part of the articles of a house and are used for the presentation of written and graphic works, facilitating their preparation. Its component elements are getting smaller and smaller, this is a trend to continue for the future. communication technology

DVD

The acronym DVD stands for versatile disc or digital video disc, and the player can read CD`s and DVD`s since both are optical discs but a DVD can store up to 25 times the amount of information that a CD, which has done that the systems that used CDs are being changed by those of new technology. They were originally used to playback laser video quality movies, other than CD movies, with pixels, where the images are not as sharp. With a very high sound and image quality, simulating a home theater, DVDs are at the top of the list of products to be purchased as entertainment appliances.

Scanner

Optical scanners are devices that, connected to a computer, allow through a beam of light to capture the colors, shapes, lights, and shadows of an image on a sheet of paper or other surface located on it, similar to a photocopier, converting the image in digital signals and from the computer screen, employing special programs to make changes and adaptations in the image. There are scanners of various sizes and capabilities to convert images of better quality, but in essence, they are very similar.

Printer

It is a device connected to a computer, capable of transferring the images or text observed on the computer screen to a sheet of paper, acetate, cardboard, etc. employing a print of them. With different technologies, methods, and printing capacities (inkjet, laser, thermal, dot, etc.), 

and data transmission, there is a great variety of them, but in the market, they are usually identified by their speed and print quality. They are used in different situations since if a large amount of data is required for review, it is better to use a dot, which appeared in 1974 and cheaper than lasers, appeared around 1984 (in black and white), which provide a print quality high, more for working with images and for the presentation of final documents.

Optical fiber

Optical fiber is a very fine thread, made of high-quality materials, which is responsible for transporting a tiny ray of light, each thread of these can transmit one of the elements that make up an image or sound quickly and completely, surpassing the transmission channels existing until now.

In 1970, fiber optics were introduced to the market after the latest breakthrough made by Donald Keck, Robert Maurer, and Peter Schultz, who manufactured the first batch of fiber optics with the quality and dimension necessary to meet the communication needs of the moment.

This technological development officially arrived in Colombia in 1988, when the International Telecommunications Center was created in Barranquilla, whose function was to connect our country with the fiber optic cable located in Puerto Colombia.
