Name that company

I trace my roots back to 1984, when a University of Texas student (my namesake) founded me with $1,000, aiming to make personal computers. I went public in 1988, started selling PCS online in 1996 and by 2001 was the world’s No. 1 computer systems provider. In 2013, I was taken private in a leveraged buyout — only to go public again in 2018. (In 2016, with partners, I bought the IT giant EMC for a whopping $67 billion.) I recently sported a market value of almost $40 billion and rake in more than $100 billion annually. Who am I?
