Communication: post, telephone, radio, television, internet and newer technology
Communication carries messages. Personal communication (post, telephone) links individuals; mass communication (radio, television, newspapers) reaches millions at once. The internet does both.
Personal and mass communication
The choice of a means of communication depends on its purpose.
The main means
- Postal service: a very old means, still important. India's network is the largest in the world, carrying letters, money orders and parcels and running savings schemes.
- Telephone: quick and affordable, now one of the most used means of all.
- Radio: began in 1927 from Mumbai and Kolkata to entertain, educate and inform. All India Radio now reaches almost every part of the country.
- Television: the national service began in 1959. Doordarshan and many private channels offer education, news and entertainment.
- Computers (information technology): used in homes, offices, shops, hospitals, banks, schools, railways and airports.
- Older means such as the telegram and the fax machine also carried messages fast.
Newer communication technology
- Internet: links computers across the world, giving information at the click of a button.
- Video conferencing: people far apart can see and talk to each other.
- E-commerce: buying and selling goods through the internet.
- Internet telephony: software that lets a computer work like a telephone, cutting call costs.
- E-mail: sends letters through the internet to anyone in the world in seconds.
- Tele-medicine: doctors advise patients thousands of kilometres away.
- Together they keep people in touch all the time, making the world a global village.
Choosing the right means
| Purpose | Suitable means |
|---|---|
| Send money to family in a village | Money order at the post office |
| Warn the whole coast about a cyclone | Radio and television broadcasts |
| Talk to a doctor in a far city | Tele-medicine or a video call |
| Buy a book from another state | E-commerce |
| Send a written message abroad at once |
A farmer can check crop prices and the weather on a mobile phone, and a village patient can consult a city doctor through tele-medicine. Cyclone warnings on radio and TV give coastal families time to move to safety.
2 marks: “Differentiate between personal and mass communication, with one example of each.” Personal communication is from one person to another, such as a letter or a phone call. Mass communication carries one message to a very large number of people at once, such as radio or television.
3 marks: “Describe any three newer means of communication and their uses.” Internet: information from anywhere at a click. Video conferencing: distant people see and talk to each other. E-commerce: online buying and selling. Tele-medicine: doctors advise distant patients. E-mail: instant, almost free letters. Any three with uses.
1 marks: “In which year did radio broadcasting begin in India?” In 1927, from Mumbai and Kolkata.
Personal is one to one (post, phone); mass is one to many (radio, TV, paper). Radio 1927, TV 1959.
