Marketing - Study on Radio and its History
Radio is the technology of signaling and communicating using radio waves. Radio waves are electromagnetic waves of frequency between 30 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves, and received by a radio receiver connected to another antenna. Radio is very widely used in modern technology, in radio communication, radar, radio navigation, remote control, remote sensing and other applications. In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking and satellite communication among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by modulating the radio signal (impressing an information signal on the radio wave by varying some aspect of the wave) in the transmitter.
Marketing - From Eliza to Alexa
Chatbots are all the rage. But the truth is, they’ve been here for most of our lifetimes... ...with the first having been invented in the 60s and now serving as the basis for modern bots. What’s different is that they’re being cast into new platforms like Facebook Messenger, Slack, Outlook, and Skype, and augmented more and more with artificial intelligence and machine learning. Chatbots – or chatterbots – used to be exclusively embedded into smart devices, but can now be expanded across mediums, whether chat or voice based. The emphasis on business use cases that dominated the spotlight in the Spring of 20161 has awakened more and more busi-nesses (and developers, some 10,000 and counting) to the opportunity.

In the freight segment, IR runs more than 9,200 trains daily. The average speed of freight trains is around 24 kilometres per hour (15 mph). Maximum speed of freight trains varies from 60 to 75 km/h (37 to 47 mph) depending upon their axle load with container special running at a peak speed of 100 km/h (62 mph). The first railway proposals for India were made in Madras in 1832.
