Telecommunication, radio, television, computers, and the internet have all evolved significantly over time. Telecommunication evolved from the telegraph to include the telephone, fiber optics, satellites, and the internet. Radio evolved from AM/FM to include satellite radio and internet radio. Television evolved from cable to direct-to-home satellite and internet TV. Computers transformed from first generation mainframes to include graphical user interfaces and the internet which began as ARPANET and allowed for downloading and streaming media.
Terrestrial television in India started with the experimental telecast starting in Delhi on 15 September 1959 with a small transmitter and a makeshift studio. Daily transmission began in 1965 as a part of All India Radio (AIR). Television service was later extended to Bombay and Amritsar in 1972.
Design and development of a web-based data visualization software for politic...Alexandros Britzolakis
Presenting a tool for identifying political popularity over Twitter. AthPPA (which stands for Athena Political Popularity Analysis) is a tool for identifying how popular a political leader is over Twitter. For the purposes of this dissertation the Twitter accounts of the most prominent Greek political leaders have been identified. Structured data such as likes, re-tweets, text-length per tweet as well as the number of subscribers per account have been visualized. Furthermore, sentiment analysis is calculated and visualized using spaCy module and a sentiment lexicon which contains a set of emotion based labeled words.
A new technological paradigm begins to be outlined at the beginning of XXI century. We live in an era that is characterized by an increasing penetration of computers in organizations; the convergence of the media, computers and telecommunications networks; automation of organizations, work processes, greater added value provided by information technology and dissemination and adoption of global technology standards. Thus, information and knowledge become the central resource for people and organizations, allowing them a strategic alignment that creates the conditions necessary to achieve the objectives and fulfill its mission. In this context, we live in a time when there is a transformation of our material culture by the mechanisms of a new technological paradigm that is organized on the basis of information technologies.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

TRENDS IN TECHNOLOGY
(Course: Mass Communication)
(Prepared by Reg no. 10-H-37, 10-H-43, 09-H-16, 09-H-32)
Telecommunication
Telecommunications involves the use of electrical devices such as the telegraph, telephone,
and teleprinter, as well as the use of radio and microwave communications, as well as fiber optics
and their associated electronics, plus the use of the orbiting satellites and the Internet. The non-
electric telegraph was invented by Claude Chappe in 1794.
Evolution of Telecommunication:
Telegraph (1795-1832)
Fax (1843)
Telephone(1849)
Radio
It started with the discovery of "radio waves" - electromagnetic waves that have the capacity
to transmit music, speech, pictures and other data invisibly through the air. Guglielmo Marconi, an
Italian inventor, proved the feasibility of radio communication. He sent and received his first radio
signal in Italy in 1895. By 1899 he flashed the first wireless signal across the English Channel and two
years later received the letter "S", telegraphed from England to Newfoundland. This was the first
successful transatlantic radiotelegraph message in 1902.
Evolution of Radio:
1) AM/FM (1897-1920)
This is the most primitive type of Radio where the signals are received by the Radio set.
There is no subscription required and it’s a free service.
2) Satellite Radio (1992)
Here the Radio is not a free service, it is just like the DTH service of Television, the customer
will need to subscribr to the provider (such as World Space Radio) and the signals can be
received in any part of the country. It has not been widely accepted.
3) Internet Radio (Internet (1994)
Internet Radio is totally computer based and there is no separate device for accessing the
content. For example www.onlineradios.in.
Television

2. Trends in Technology
As a 23-year-old German university student, Paul Nipkow proposed and patented the first
electromechanical television system in 1884. In 1926, just a little after Jenkins, a British inventor
known as John Logie Baird, was the first person to have succeeded in transmitting moving pictures.
1) CABLE (1948)
The channels were received by the use of cables. A satellite receiver would be placed by the
Cable Operator at the TV centre and all the households would be connected by the use of
cables.
2) DTH (Direct To Home) (1977)
It eliminated the need for a Cable Operator and long cables, because people could set up
their own dish and connect it to their Television, via set top box. This has made TV viewing
hassle free. And the digital encoding made the picture quality much more superior.
3) INTERNET TV (1998)
Internet TV is yet to be fully developed in Countries like India. The Television is connected to
broadband Internet and live video streaming is received by the television. Eg. Tvonline
Computer
Computer is any device which aids humans in performing various kinds of computations or
calculations. The simplest form of a computer was an “Abacus”, which helped in doing arithmetic
calculation. Possibly the most significant of those shifts was the invention of the Graphical User
Interface (GUI).
Transformation of Computer:
First Generation (1940s – 1950s) (ENIAC)
Second Generation (1955 – 1960)
Third Generation (1960s)
Fourth Generation (1971 – present)
Internet
The Internet was the result of some visionary thinking by people in the early 1960s who saw
great potential value in allowing computers to share information on research and
development in scientific and military fields. The Internet, then known as ARPANET, was
brought online in 1969 under a contract let by the renamed Advanced Research Projects
Agency (ARPA) which initially connected four major computers at universities in the South
Western US (UCLA, Stanford Research Institute, UCSB, and the University of Utah).
A) Download
• In computer networks, to download means to receive data to a local system
from a remote system, or to initiate such a data transfer.
2|Page
3. Trends in Technology
• Examples of a remote system from which a download might be performed
include a web server, FTP server, email server, or other similar systems.
B) Streaming media (1996)
• Streaming media is multimedia that is constantly received by and presented
to an end-user while being delivered by a provider.
• “To stream", refers to the process of delivering media in this manner; the
term refers to the delivery method of the medium rather than the medium
itself.
