Condoling the death of Apple founder Steve Jobs, Ratan Tata said the world has lost a great business leader and a great visionary.
"He will be deeply mourned and greatly missed," he said in a statement.
Jobs innovativeness gave the world the personal computer, iPod, iPhone and iPad, which changed the life of many, Tata said.
Apple's products, under his leadership, have had a profound impact on mankind, unequaled by any other company in the information and technology space, he added.
Jobs invented and masterfully marketed ever-sleeker gadgets that transformed everyday technology, from the personal computer to the iPod and iPhone.
Jobs died at the age of 56 after a long battle with cancer yesterday.
Jobs will be a great source of inspiration for generations to come, a top official of IT major Cognizant said on Thursday.
"In the sad demise of Steve Jobs, the world has lost a sterling technology visionary and entrepreneur who thought well ahead of his time, challenged conventions and stereotypes, and pushed the envelope of innovation like few others," Lakshmi Narayanan, Vice-Chairman, Cognizant said.
In his condolence message, Narayanan said that more than the gadgets Jobs pioneered, his legacy will be the "sheer brilliance of the myriad ways in which he helped the world experience and appreciate its digital future with a sense of profound expectation and wonderment."
"As someone who almost single-handedly transformed the world of computing and redefined the concept of pocket devices, Jobs will continue to be a great source of inspiration for generations to come," Narayanan said in the message.
Gaming company IndiaGames CEO Vishal Gondal said Jobs was one of his idols.
He is one of my idols as he runs the biggest fashion company in the world,” he said, alluding to Apple's iconic design heritage.
