Step 1: Understanding the Concept:
Communication systems are the backbone of modern society, enabling the transfer of information across distances. They are categorized into personal communication (letters, phones) and mass communication (radio, TV, internet). Modern communication relies heavily on advanced infrastructure like satellites and high-speed fiber optics.
Step 2: Detailed Explanation:
Let's evaluate each statement one by one:
Statement i: Radio and Television are designed to reach a vast audience simultaneously, which is the definition of "mass communication." They provide entertainment, education, and news to millions. This is correct.
Statement ii: Satellites in orbit around the Earth are crucial for capturing data about the Earth's surface (Remote Sensing) and monitoring atmospheric changes (Weather Forecasting). India's IRS (Indian Remote Sensing) and INSAT (Indian National Satellite) systems are key examples. This is correct.
Statement iii: The Internet uses digital technology to transmit data almost instantaneously across the globe. Unlike physical mail or even traditional radio, the internet allows for two-way, high-speed, multi-media interaction. This is correct.
Statement iv: Radio broadcasting in India began in 1923. It became the Indian State Broadcasting Service in 1930 and was renamed All India Radio (AIR) in 1936. In 1957, the name "Akashvani" was officially adopted for the domestic service. This is correct.
Since all statements are factually accurate within the context of Indian geography and history, option (D) is the correct choice.
Step 3: Final Answer:
All the provided statements regarding mass media, satellite utility, internet speed, and the history of All India Radio are factually true. Thus, option (D) is the correct choice.
