India To Send World's Last Telegram
New submitter afarhan writes "India will pull the plug on its 160-year-old telegram service on 14 July, this year. This will probably be the last telegram ever sent in the world. However, telegrams are still relevant in this vast country. More than 500 million people are still without access to a phone or Internet. For these people, telegram still remains the only digital communication available. 'At their peak in 1985, 60 million telegrams were being sent and received a year in India from 45,000 offices. Today, only 75 offices exist, though they are located in each of India's 671 districts through franchises. And an industry that once employed 12,500 people, today has only 998 workers.' In India, telegram is also considered a legal correspondence."
Well sorry for the Article but it's actually false :) Telegram is still alive and kicking in Europe ... for instance in Belgium where you can still send Telegrams right now !
Here is the national telecommunication operator page about it :

> binary, by itself, doesn't (I'm pretty sure but may be mistaken) confer "digital" status.
The defining distinction between digital and analog is that analog can represent a continuous range, whereas digital can only represent specific values. A phonograph, for example, can represent an infinite range of values between silence and full volume. A CD, on the other hand, can only encode certain volumes, not any in between. That's what makes a phonograph analog and a CD digital. Therefore, binary is BY DEFINITION digital - it uses just two values, not an infinite range
That's good and bad for both. With digital, you get back EXACTLY what you debt, with no degradation. With analog, you can receive a signal even if it can't be received perfectly, because it can receive 0.46 when its not possible to distinguish between 0 and 1.
Since traditional telegraphs consist of only dots and dashes, they are digital, and binary.
Actually no. Silences are meaningful in morse, so it's ternary, not binary.
You even have short and long silences, thus we are talking base 4.
