Dell Inc: is a multinational information technology corporation based in Round Rock, Texas, United States, that develops, sells and supports computers and related products and services. Bearing the name of its founder, Michael Dell, the company is one of the largest technological corporations in the world, employing more than 96,000 people worldwide. Dell had 46,000 employees as of Jan. 30. About 22,200 of those, or 48.3 percent, were in the United States, while 23,800 people, or 51.7 percent, worked in other countries, according to a filing with the Securities and Exchange Commission. Dell is listed at #38 on the Fortune 500 (2010). Fortune also lists Dell as the #5 most admired company in its industry.

Dell has grown by both organic and inorganic means since its inception—notable mergers and acquisitions including Alienware (2006) and Perot Systems (2009). As of 2009, the company sold personal computers, servers, data storage devices, network switches, software, and computer peripherals. Dell also sells HDTVs, cameras, printers, MP3 players and other electronics built by other manufacturers. The company is well known for its innovations in supply chain management and electronic commerce.

On May 3, 2010, Fortune Magazine listed Dell as the 38th largest company in the United States and the 5th largest company in Texas by total revenue. It is the 2nd largest non-oil company in Texas (behind AT&T) and the largest company in the Austin area.

Dell traces its origins to 1984, when Michael Dell created PCs Limited while a student at the University of Texas at Austin. The dorm-room headquartered company sold IBM PC-compatible computers built from stock components. Michael Dell started trading in the belief that by selling personal computer systems directly to customers, PCs Limited could better understand customers' needs and provide the most effective computing solutions to meet those needs.[4] Michael Dell dropped out of school in order to focus full-time on his fledgling business, after getting about $300,000 in expansion-capital from his family.

In 1985, the company produced the first computer of its own design — the "Turbo PC", sold for US$795. PCs Limited advertised its systems in national computer magazines for sale directly to consumers and custom assembled each ordered unit according to a selection of options. The company grossed more than $73 million in its first year of trading.

The company changed its name to "Dell Computer Corporation" in 1988 and began expanding globally—first in Ireland. In June 1988, Dell's market capitalization grew by $30 million to $80 million from its June 22 initial public offering of 3.5 million shares at $8.50 a share. In 1992, Fortune magazine included Dell Computer Corporation in its list of the world's 500 largest companies, making Michael Dell the youngest CEO of a Fortune 500 company ever.

In 1996, Dell began selling computers via its web site, and in 2002, Dell expanded its product line to include televisions, handhelds, digital audio players, and printers. Dell's first acquisition occurred in 1999 with the purchase of ConvergeNet Technologies. In 2003, the company was rebranded as simply "Dell Inc." to recognize the company's expansion beyond computers. From 2004 to 2007, Michael Dell stepped aside as CEO, while long-time Dell employee Kevin Rollins took the helm. During that time, Dell acquired Alienware, which introduced several new items to Dell products, including AMD microprocessors. To prevent cross-market products, Dell continues to run Alienware as a separate entity but still a wholly-owned subsidiary.

Lackluster performance, however, in its lower-end computer business prompted Michael Dell to take on the role of CEO again. The founder announced a change campaign called "Dell 2.0," reducing headcount and diversifying the company's product offerings. The company acquired EqualLogic on January 28, 2008 to gain a foothold in the iSCSI storage market. Because Dell already had an efficient manufacturing process, integrating EqualLogic's products into the company drove manufacturing prices down.

In 2009, Dell acquired Perot Systems, a technology services and outsourcing company founded by H. Ross Perot.

On September 21, 2009, Dell announced its intent to acquire Perot Systems (based in Plano, Texas) in a reported $3.9 billion deal. Perot Systems brought applications development, systems integration, and strategic consulting services through its operations in the U.S. and 10 other countries. In addition, it provided a variety of business process outsourcing services, including claims processing and call center operations.

On August 16, 2010, Dell announced its intent to acquire the data storage company 3PAR. On September 2, 2010 Hewlett-Packard offered $33 a share, which Dell declined to match.
