Jio

Jio, also known as Reliance Jio and officially as Reliance Jio Infocomm Limited (RJIL), is an upcoming provider of mobile telephony, broadband services, and digital services in India. Formerly known as Infotel Broadband Services Limited, Jio will provide 4G services on a pan-India level using LTE technology. The telecom leg of Reliance Industries Limited, it was incorporated in 2007 and is based in Mumbai, India.

The services were beta launched to Jio's partners and employees on December 27, 2015 on the eve of 83rd birth anniversary of late Dhirubhai Ambani, founder of Reliance Industries. It will commercially launch its services in March 2016.

History

In June 2010, Reliance Industries (RIL) bought a 95% stake in Infotel Broadband Services Limited (IBSL) for Rs 4,800 crore. Although unlisted, IBBL was the only firm to win broadband spectrum in all 22 zones in India in the 4G auction that took place earlier that year. Later continuing as RIL's telecom subsidiary, Infotel Broadband Services Limited was renamed as Reliance Jio Infocomm Limited (RJIL) in January 2013.

Prime number

A prime number (or a prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself. A natural number greater than 1 that is not a prime number is called a composite number. For example, 5 is prime because 1 and 5 are its only positive integer factors, whereas 6 is composite because it has the divisors 2 and 3 in addition to 1 and 6. The fundamental theorem of arithmetic establishes the central role of primes in number theory: any integer greater than 1 can be expressed as a product of primes that is unique up to ordering. The uniqueness in this theorem requires excluding 1 as a prime because one can include arbitrarily many instances of 1 in any factorization, e.g., 3, 1 · 3, 1 · 1 · 3, etc. are all valid factorizations of 3.

The property of being prime (or not) is called primality. A simple but slow method of verifying the primality of a given number n is known as trial division. It consists of testing whether n is a multiple of any integer between 2 and . Algorithms much more efficient than trial division have been devised to test the primality of large numbers. These include the Miller–Rabin primality test, which is fast but has a small probability of error, and the AKS primality test, which always produces the correct answer in polynomial time but is too slow to be practical. Particularly fast methods are available for numbers of special forms, such as Mersenne numbers. As of January 2016, the largest known prime number has 22,338,618 decimal digits.
