Dell Inc.

Descrpition:
The name Dell may be synonymous with "direct," but the computer giant has a more diverse approach to the market these days. The world's #1 direct-sales computer vendor provides a broad range of computer products for the consumer and enterprise markets. In addition to a full line of desktop and notebook PCs, Dell offers network servers, workstations, storage systems, printers, projectors, and Ethernet switches. It also markets third-party software and peripherals. Dell's growing services unit provides systems integration, support, and training. The company began selling through retail stores in 2007.

Microsoft Corporation

Description:
Microsoft's ambitions are anything but small. The world's #1 software company provides a variety of products and services, including its Windows operating systems and Office software suite. The company has expanded into markets such as video game consoles, server and storage software, and digital music players. Microsoft has reached settlements to end a slew of antitrust investigations and lawsuits, including agreeing to uniformly license its operating systems and allowing manufacturers to include competing software with Windows. In 2008 Microsoft made repeated efforts to acquire Yahoo! but was rebuffed by that company's board of directors.
