Macintosh vs. IBM essays

Macintosh vs. IBM essays The IBM and Macintosh computers have been in competition with each other for years, and each of them have their strong points. They both had their own ideas about where they should go in the personal computer market. They also had many developments, which propelled themselves over the other. It all started when Thomas John Watson became president of Computing Tabulating Recording in 1914, and in 1924 he renamed it to International Business Machines Corporation. He eventually widened the company lines to include electronic computers, which was extremely new in those days. In 1975 IBM introduced their first personal computer (PC) which was called the Model 5100. It carried a price tag of about $9,000 which caused it to be out of the main stream of personal computers, even though their first computer did not get off to as big as a start they had hoped it did not stop them from continuing on. Later on IBM teamed up with Microsoft to create an operating system to run their new computers, because their software division was not able to meet a deadline. They also teamed up with Intel to supply its chips for the first IBM personal computer. When the personal computer hit the market it was a major hit and IBM became a strong power in electronic computers. Phoenix Technologies went through published documentation to figure out the internal operating system (BIOS) in the IBM. In turn, they designed a BIOS of their own which could be used with IBM computers. It stood up in courts and now with a non IBM BIOS, the clone was created. Many manufacturers jumped in and started making their own IBM Compatible computers, and IBM eventually lost a big share in the desktop While IBM was just getting started in the personal computer market, Apple was also just getting on its feet. It was founded by Steve Jobs and Steve Wozniak in 1976. They were both college drop outs, Steve Jobs out of Reed Col...

Stegoceras - Facts and Figures

Stegoceras - Facts and Figures Name: Stegoceras (Greek for roof horn); pronounced STEG-oh-SEH-rass Habitat: Forests of western North America Historical Period: Late Cretaceous (75 million years ago) Size and Weight: Up to six feet long and 100 pounds Diet: Plants Distinguishing Characteristics: Light build; bipedal posture; extremely thick skull in males About Stegoceras Stegoceras was the prime example of a pachycephalosaur (thick-headed lizard)a family of ornithischian, plant-eating, two-legged dinosaurs of the late Cretaceous period, characterized by their extremely thick skulls. This otherwise sleekly built herbivore had a noticeable dome on its head made of almost-solid bone; paleontologists speculate that Stegoceras males held their heads and necks parallel to the ground, build up a head of speed, and rammed each other on the noggins as hard as they could. (They may also, secondarily, have used their heads to butt away the flanks of encroaching tyrannosaurs, though we have no objective proof of this behavior.) The sensible question is: What was the point of this Three Stooges routine? Extrapolating from the behavior of present-day animals, its likely that Stegoceras males head-butted each other for the right to mate with females. This theory is supported by the fact that researchers have discovered two distinct varieties of Stegoceras skulls, one of which is thicker than the other and presumably belonged to the males of the species. (However, some paleontologists dispute this theory, noting that such high-speed collisions would tend to be disadvantageous from an evolutionary perspectivefor example, a dizzy, concussed Stegoceras could easily be picked off by a hungry raptor!) The type specimen of Stegoceras was named by the famous Canadian paleontologist Lawrence Lambe in 1902, following its discovery in the Dinosaur Provincial Park formation of Alberta, Canada. For a few decades, this unusual dinosaur was believed to be a close relative of Troodon (which was actually a saurischian rather than an ornithischian dinosaur, and thus resided on an entirely different branch of the dinosaur family tree), until the discovery of further pachycephalosaur genera made its provenance clear. For better or for worse, Stegoceras is the standard by which all subsequent pachycephalosaurs have been judgedwhich is not necessarily a good thing, considering how much confusion still exists about the behavior and growth stages of these dinosaurs. For example, the presumed pachycephalosaurs Dracorex and Stygimoloch may have been either juvenile, or unusually aged adults, of the well-known genus Pachycephalosaurus and at least two fossil specimens that were initially assigned to Stegoceras have since been promoted to their own genera, Colepiocephale (Greek for knucklehead) and Hanssuesia (named after the Austrian scientist Hans Suess).
