A new theory that could yield more-reliable communication protocols for digital devices has been developed by researchers led by an Indian-origin scientist.Communication protocols for digital devices are very efficient but also very brittle: They require information to be specified in a precise order with a precise number of bits. If sender and receiver - say, a computer and a printer - are off by even a single bit relative to each other, communi cation between them breaks do.

Similarly, the first topic Sudan and his colleagues began investigating is compression, or the minimum number of bits that one device would need to send another in order to convey all the information in a data file.Existing data compression schemes do exploit statistical regularities in data.

Another Chinese smartphone brand, Vivo has launched its product in India Vivo has bought their slimmest smart phone called Vivo X5 Max to the market for a high price tag of Rs 32,980. The Vivo X5 Max measures just 4.75mm thick which makes it slimmer than the Gionee S5.1 which is 5.1mm thick as well as the Oppo R5 which is 4.85mm thick.
