Problem: Dell has been attempting to offset its declining PC business, which still accounted for half of its revenue and generates steady cash flow, by expanding into the enterprise market with servers, networking, software, and services. It avoided many of the acquisition writedowns and management turnover that plagued its chief rival Hewlett Packard. Dell also managed some success in taking advantage of its high-touch direct sales heritage to establish close relationships and design solutions for clients. Despite spending $13 billion on acquisitions to diversify its portfolio beyond hardware, the company was unable to convince the market that it could thrive or made the transformation in the post-PC world, as it suffered continued declines in revenue and share price. Dell's market share in the corporate segment was previously a "moat" against rivals but this has no longer been the case as sales and profits have fallen precipitously.
Who was Dell's main business rival?
The answer is the following: Hewlett Packard

Problem: In 1911 arsphenamine, the first synthetic anti-infective drug, was developed by Paul Ehrlich and chemist Alfred Bertheim of the Institute of Experimental Therapy in Berlin. The drug was given the commercial name Salvarsan. Ehrlich, noting both the general toxicity of arsenic and the selective absorption of certain dyes by bacteria, hypothesized that an arsenic-containing dye with similar selective absorption properties could be used to treat bacterial infections. Arsphenamine was prepared as part of a campaign to synthesize a series of such compounds, and found to exhibit partially selective toxicity. Arsphenamine proved to be the first effective treatment for syphilis, a disease which prior to that time was incurable and led inexorably to severe skin ulceration, neurological damage, and death.[citation needed]
What complications are associated with Syphilis?
The answer is the following: severe skin ulceration, neurological damage, and death

Problem: The band have released a total of eighteen number one albums, eighteen number one singles, and ten number one DVDs worldwide, making them one of the world's best-selling music artists. Queen have sold over 150 million records, with some estimates in excess of 300 million records worldwide, including 34.5 million albums in the US as of 2004. Inducted into the Rock and Roll Hall of Fame in 2001, the band is the only group in which every member has composed more than one chart-topping single, and all four members were inducted into the Songwriters Hall of Fame in 2003. In 2009, "We Will Rock You" and "We Are the Champions" were inducted into the Grammy Hall of Fame, and the latter was voted the world's favourite song in a global music poll.
How many albums has Queen sold worldwide?
The answer is the following: over 150 million

Problem: Firstly conceived and still used today for optical storage devices (CD-RW drives, DVD drives, etc.), several manufacturers offer external portable USB hard disk drives, or empty enclosures for disk drives. These offer performance comparable to internal drives, limited by the current number and types of attached USB devices, and by the upper limit of the USB interface (in practice about 30 MB/s for USB 2.0 and potentially 400 MB/s or more for USB 3.0). These external drives typically include a "translating device" that bridges between a drive's interface to a USB interface port. Functionally, the drive appears to the user much like an internal drive. Other competing standards for external drive connectivity include eSATA, ExpressCard, FireWire (IEEE 1394), and most recently Thunderbolt.
What do external portable USB hard drive disks offer?
The answer is the following:
performance comparable to internal drives
