Communication Technology

We all know that communication technology  as information refers to all equipment and programs that are used to process and  communicate information.

    What is Communication Technology?

    

     Communication is the transfer of information and some means of ensuring that what is sent is also received. Technology increases the ways in which information can be communicated, the speed of transmission, and the total volume that can be handled at any one time. Students need to experience firsthand how technology helps people communicate more information to more people in less time, with greater accuracy and fewer misunderstandings. In this brief lesson, students will try out a few innovative examples of communications technologies and explain how they transform patterns of sound or light into patterns of electricity.

    Types of Communication Technology: Radio, Television, Telephone, Internet

• Radio - In 1906, Reginald Fessenden, creator of the first sophisticated radio transmitter, expanding on the ideas of Guglielmo Marconi, sent music and speech across the airwaves. This invention of the radio allowed sound and information to be broadcast to an extremely wide audience. Radio reached its golden age during the 1920s, and companies advertised their products to consumers around the world. During the 1930s radio expanded further into news, politics, vaudeville routines and sporting events, broadcasting into millions of homes every day.
• Television - was introduced to the public in 1946, even though it had been experimented with since the late 1920s. Television exploded in homes around the world, going from 940,000 households in the beginning to 20 million by 1953. Corporations suddenly had the opportunity to show their products, not just describe them. Over the following decades, television became the predominant source of communication to a wide audience, and it changed the political and cultural landscape forever. People were suddenly able to witness iconic events, such as the first moon landing and the progression of the civil rights movement.
• Telephone - Alexander Graham Bell revolutionized the way people communicate with his patent on the telephone in 1876. Over the past century, advances in technology have replaced the heavy hardware and metal wiring of the original design with lightweight micro circuitry. These advancements have also allowed for the transition from landlines to wireless, freeing people to communicate from remote locations. All over the world, millions of people can talk to each other, expanding businesses and improving relationships that might not otherwise have survived across long distances.
• Internet - The creation of the Internet allowed computer networks from around the globe to network with each other, giving individuals access to an incredible wealth of information. In 2010, about half of the world's population has access to the Internet, growing from only 6 percent of the population in 2000. Email, social networks, newsgroups and video transmission have connected the world like never before. Privacy concerns have arisen with the proliferation of the Internet, especially with government monitoring and certain social networking sites, but the Internet has woven itself into the fabric of society and business. High-speed connections allow for an immense amount of information to be transferred in seconds.

    Four types of communication:

     Human to Machine is a communication formed where humans interact variety of devices like sensors and actuators. It can improve quality of life through the accessibility to smart devices which has sensory inputs and assists with everyday tasks.

     Human to Human is said that we communicate to request help, to inform others and to share attitudes as a way of bonding.

    Machine to Human is a form of communication in which humans co-work with (AI) Artificial Intelligence and other machines as opposed to utilizing them as tools or devices.

    Machine to Machine can be used to describe any technology that enables network devices to exchange information and performs action without the help of humans.
