The world's richest man and Microsoft co-founder Bill Gates tops the list of "100 Richest People In Tech", released by Forbes earlier this month.
The net worth of Gates stood at $79.6 billion. He has been selling his shares in Microsoft since he left the company board in 2014.
"Less than 13% of his estimated fortune now comes from Microsoft stock," Forbes said.
Almost all the 100 top billionaires in the world of technology are "self-made", with only a few of them inheriting fortunes from their family members. The net worth of these 100 tech billionaires stood at $842.9 billion.
"The average age of the group is 53, which is a decade younger than the average age of all billionaires; 15 of the 100 are under age 40," it says.
Wipro chairman Azim Premji (net worth of $ 17.4 billion) and HCL founder Shiv Nadar ($ 14.4 billion) are the only Indian businessmen who featured among the top 20 in the list. Premji stood at 13th spot in the list followed by Nadar.
Premji, who was the "most generous Indian' of 2014", has allocated an additional 18 percent of the stake he holds in the company for philanthropy, taking his total contribution for charity to more than 50 percent.
