The Quran most likely existed in scattered written form during Muhammad's lifetime. Several sources indicate that during Muhammad's lifetime a large number of his companions had memorized the revelations. Early commentaries and Islamic historical sources support the above-mentioned understanding of the Quran's early development. The Quran in its present form is generally considered by academic scholars to record the words spoken by Muhammad because the search for variants has not yielded any differences of great significance.[page needed] University of Chicago professor Fred Donner states that "...there was a very early attempt to establish a uniform consonantal text of the Quran from what was probably a wider and more varied group of related texts in early transmission. [...] After the creation of this standardized canonical text, earlier authoritative texts were suppressed, and all extant manuscriptsdespite their numerous variantsseem to date to a time after this standard consonantal text was established." Although most variant readings of the text of the Quran have ceased to be transmitted, some still are. There has been no critical text produced on which a scholarly reconstruction of the Quranic text could be based. Historically, controversy over the Quran's content has rarely become an issue, although debates continue on the subject.
What was done to the Quranic text late in its history leaving few markedly different variants?
A: unanswerable

In the mid-1990s, Dell expanded beyond desktop computers and laptops by selling servers, starting with low-end servers. The major three providers of servers at the time were IBM, Hewlett Packard, and Compaq, many of which were based on proprietary technology, such as IBM's Power4 microprocessors or various proprietary versions of the Unix operating system. Dell's new PowerEdge servers did not require a major investment in proprietary technologies, as they ran Microsoft Windows NT on Intel chips, and could be built cheaper than its competitors. Consequently, Dell's enterprise revenues, almost nonexistent in 1994, accounted for 13 percent of the company's total intake by 1998. Three years later, Dell passed Compaq as the top provider of Intel-based servers, with 31 percent of the market. Dell's first acquisition occurred in 1999 with the purchase of ConvergeNet Technologies for $332 million, after Dell had failed to develop an enterprise storage system in-house; ConvergeNet's elegant but complex technology did not fit in with Dell's commodity-producer business model, forcing Dell to write down the entire value of the acquisition.
Which company did Dell exceed as a server provider?
A: Compaq
