Dell Inc. is an American privately owned multinational computer technology company based in Round Rock, Texas, United States, that develops, sells, repairs, 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 103,300 people worldwide.[3]

Dell sells personal computers (PCs), servers, data storage devices, network switches, software, computer peripherals, HDTVs, cameras, printers, MP3 players, and electronics built by other manufacturers. The company is well known for its innovations in supply chain management and electronic commerce, particularly its direct-sales model and its "build-to-order" or "configure to order" approach to manufacturing—delivering individual PCs configured to customer specifications.[4][5] Dell was a pure hardware vendor for much of its existence, but with the acquisition in 2009 of Perot Systems, Dell entered the market for IT services. The company has since made additional acquisitions in storage and networking systems, with the aim of expanding their portfolio from offering computers only to delivering complete solutions for enterprise customers.[6][7]

Dell was listed at number 51 in the Fortune 500 list, until 2014.[8] After going private in 2013, the newly confidential nature of its financial information prevents the company from being ranked by Fortune. In 2014 it was the third largest PC vendor in the world after Lenovo and HP.[9] Dell is currently the #1 shipper of PC monitors in the world.[10] Dell is the sixth largest company in Texas by total revenue, according to Fortune magazine.[11] It is the second largest non-oil company in Texas – behind AT&T – and the largest company in the Greater Austin area.[12] It was a publicly traded company (NASDAQ: DELL), as well as a component of the NASDAQ-100 and S&P 500, until it was taken private in a leveraged buyout which closed on October 30, 2013.
