Dell Inc. is an American multinational computer technology company based in Round Rock, Texas, which manufactures, sells, repairs, and supports personal computers (PCs), servers, data storage devices, network switches, computer software, computer peripherals, high-definition televisions, cameras, printers, and electronics built by other manufacturers. The company is known for its innovations in supply chain management and e-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.

Founded in 1984 as PC's Limited by Michael Dell, in which the company was later eponymously renamed, they sold IBM PC compatible computers in his dormitory room at the University of Texas at Austin. As the company grew, it began its operations in North Austin, Texas in 1986, going public in 1988 and transforming the company from a fast-growing medium-sized firm into a billion-dollar enterprise. Throughout the late 1980s, Dell had a market share of 1%, compared to 30% for IBM, 8.2% for Apple Computer, 5.2% for Compaq, 5% for Olivetti, and 4.4% for Zenith Electronics. During the 1990s, the company experienced steady growth and it gained market share from competitors even during industry slumps and moved their headquarters from North Austin to Round Rock, Texas. Beginning in the 2000s, Dell sales grew slowly and was heavily dependent on U.S. corporate PC market, losing ground to Hewlett-Packard. This led to downsizing of the company and expanding retail operations internationally while declining its operations in the United States.
