A process in which a person, group of people, or an organization sends a message through a channel of communication to a large group of anonymous and heterogeneous people and organizations is called Mass Communication System. All India Radio broadcasts a variety of programmes related to information, education and entertainment. Television broadcasting has emerged as the most effective audio-visual medium for disseminating information and educating masses. Satellites are mode of communication in themselves as well as they regulate the use of other means of communication.
Human beings have evolved different methods of communication over time. In earlier times, the messages were delivered by beating the drum or hollow tree trunks, giving indications through smoke or fire or with the help of fast runners. Horses, camels, dogs, birds and other animals were also used to send messages. Initially, the means of communication were also the means of transportation. Invention of post office, telegraph, printing press, telephone, satellite, etc has made the communication much faster and easier.
Oil and Gas Pipelines are the most convenient and efficient mode of transporting liquids and gases over long distances. Even solids can also be transported by pipelines after converting them into slurry. Oil India Limited (OIL) under the administrative set up of the Ministry of Petroleum and Natural Gas is engaged in the exploration, production and transportation of crude oil and natural gas. Asia’s first cross country pipeline covering a distance of 1,157 km was constructed by OIL from Naharkatiya oilfield in Assam to Barauni refinery in Bihar.
Air transport is the fastest means of movement from one place to the other. It has reduced distances by minimising the travel time. Air transport in India made a beginning in 1911 when airmail operation commenced over a little distance of 10 km between Allahabad and Naini. But its real development took place in post-Independent period. The Airport Authority of India is responsible for providing safe, efficient air traffic and aeronautical communication services in the Indian Air Space.
Waterways are an important mode of transport for both passenger and cargo traffic in India. It is the cheapest means of transport and is most suitable for carrying heavy and bulky material. It is a fuel-efficient and eco-friendly mode of transport. The water transport is of two types– (a) inland waterways, and (b) oceanic waterways. Inland waterways are s the chief mode of transport before the advent of railways. Oceanic routes play an important role in the transport sector of India’s economy.
Rail Transport network in India is one of the longest in the world. The first railway on Indian sub-continent ran over a stretch of 21 miles from Bombay to Thane. Indian Railways, the premier transport organization of the country is the largest rail network in Asia and the world's second largest under one management. Indian Railway is controlled by the Railway Ministry and the Railway Board and for better services and control, the rail transportation is divided into 16 zones or division with headquarter.
India has one of the largest road networks in the world. For the purpose of construction and maintenance, roads are classified as National Highways (NH), State Highways (SH), Major District Roads and Rural Roads. The National Highways Authority of India (NHAI) is the apex body to improve the quality of the National Highways. State highways are constructed and maintained by state governments. The Border Road Organisation (BRO) was established in May 1960 for accelerating economic development and strengthening defence preparedness.
If the amount of export and import roughly equals or export is more than import, the country is supposed to have a balanced trade or favourable trade. In a way, it indicates towards the good condition of a country’s economy. The use of transport and communication depends upon our need to move things from place of their availability to the place of their use. Human-beings use various methods to move goods, commodities, ideas from one place to another.

The Engineering Industry is the largest among all industrial sectors in India. It incorporates diverse segments of industry which can be broadly divided into two segments, namely, heavy engineering and light engineering. It is relatively less fragmented at the top, as the competencies required are high, while it is highly fragmented at the lower end (e.g. unbranded transformers for the retail segment) and is dominated by smaller players. The engineering industry in India manufactures a wide range of products, with heavy engineering goods accounting for bulk of the production.
Petro-Chemical group of industries have been growing very fast in India. A variety of products come under this category of industries. In 1960s, demand for organic chemicals increased so fast that it became difficult to meet this demand. At that time, petroleum refining industry expanded rapidly. Many items are derived from crude petroleum, which provide raw materials for many new industries; these are collectively known as petrochemical industries. This group of industries is divided into four sub-groups: Polymers, Synthetic fibres, Elastomers and Surfactant intermediate.
Chemical fertilizers played vital role in the success of Green Revolution in India and consequent self-reliance in food-grain production, the Government of India has been consistently pursuing policies conducive to increase the availability and consumption of fertilizers in the country. The country has achieved near self-sufficiency in production capacity of urea with the result that India could substantially manage its requirement of nitrogenous fertilizers through the indigenous industry.
Cement is essential for construction activity such as building houses, factories, bridges, roads, airports, dams and for other commercial establishments. This industry requires bulky and heavy raw materials like limestone, silica, alumina and gypsum. Coal and electric power are needed apart from rail transportation. The industry has strategically located plants in Gujarat that have suitable access to the market in the Gulf countries. The first cement plant was set up in Chennai in 1904.
Aluminium Industry is the second most important metallurgical industry in India. Aluminium has gained popularity as a substitute of steel, copper, zinc and leads in a number of industries because it is light metal, resistant to corrosion, a good conductor of heat, malleable and becomes strong when it is mixed with other metals. There are 8 aluminium smelting plants in the country located in Odisha (formerly Orissa) (Nalco and Balco), West Bengal, Kerala, Uttar Pradesh, Chhattisgarh, Maharashtra and Tamil Nadu.
India has 12 major and 187 non-major ports. The Indian ports and shipping industry plays a vital role in sustaining growth in the country’s trade and commerce.
