Building a Computer - 2328 Words

With increasing popularity of computer games, and multimedia home PC users often need an unexpensive computer system upgrade. By building a custom computer one is able to combine componenets, and operating system to provide maximal gaming performance. Computers are often called number manipulators, because of their ability to run millions of mathematical operations per second (White 43). Computers use binary system of numbers, which allows them to operate system of microscopic switches called transistors found inside of computer chips. Binary system is defined as counting system that uses two digits one and zero (Gookin 49). A transistor is a basic building block of microchips; transistors are combined in formations called logic gates†¦show more content†¦The hard disk is a combination of electronic and mechanical portions, which makes it the one of the slowest parts of the computer (White 87). A graphic card is usually plugged into one of the expansion slots, which are meta llic contacts on the motherboard (White 119). One of the most common expansion slots is PCI Ââ€" peripheral components interconnect. PCI are most commenly white slots used to attach a graphic or sound card, also modem or network card (White 120). Latest expansion slot used for graphic cards only is AGP Ââ€" accelerated graphic port, which is faster than PCI (White 121). Both PCI and AGP based adapters use SVGA Ââ€" super video graphics array as a modern standard, which added new capabilities, such as higher resolution and color depth to the previous VGA interface. Super VGA allows as many as 16 million colors also called 32-bit color, or true color(Stephen 1253). There are three major factors defining the speed of a graphic adapter, overall performance depends on the chipset speed, performance and capacity of graphic random access memory and the expansion slot architecture (Stephen 1258). One of the other factors defining speed of a video adapter is the software driver. Even the finest accelerator board hardware can bog-down when run with careless, loosely written code(Stephen 1259). Graphic cards have their own BIOS software which is firmware, or permanently recorded in a memory device such as ROM Ââ€" read only memory, and usually can not be modified.Show MoreRelatedBuilding A Computer And The Computer1222 Words   |  5 PagesBuilding a computer When people hear that some people build their own computer, they automatically decide that it must be some very challenging task that requires a wizard of all things electronic.

Summary Of Homer s The Sleep - 1507 Words

Nayla Basma Professor Meisel Literature Humanities- Sec. 23 3 October 2015 To Sleep, or Not to Sleep? In Homer’s Iliad, sleep–albeit a seemingly simple verb–is a multifaceted concept that highlights the strengths and weaknesses of humanity within various characters of the epic poem. On one hand, sleep is viewed as something to be avoided, a weakness bound to result in destructive consequences. On the other hand, sleep is a tool that provides restoration and gives one a respite from their reality, whether it be temporarily or permanently. Together, the two features of sleep portray the humanity of a breadth of characters, ranging from the fully mortal Diomedes to the the all-powerful Zeus. In the end, it is clear to the readers that although the central figures within the poem constantly strive to perform at an â€Å"immortal† level, the mortal element of sleep consistently arises, humanizing the Homeric characters of the Iliad and glorifying the human experience. The concept of sleep is critical to our understanding of the leaders and warriors within the story, whose survival is contingent on being prepared for battle at all times. To illustrate, consider the Thracian king and his twelve soldiers, who are all killed in Book X by both Odysseus and Diomedes while sleeping. Sleep thus must be eschewed, since it is proven to be a time when vulnerability surfaces. Contrary to the Thracian king, King Agamemnon fails to sleep due to his trepidations for his people’s future: TheShow MoreRelatedHoarding: Worldwide Issue Essay1189 Words   |  5 Pageswhen the collyers brothers were buried alive thus increase the fascination and anxiety during the 1930s to today (Herring 2011, p. 159).

Lactose Tolerance Free Essays

Lactose is the most important carbohydrate in milk. It cannot be absorbed in the intestine, but needs to be split in two molecules by the enzyme lactase. In newborns the (very rare) absence of the enzyme is lethal unless special food can be provided. We will write a custom essay sample on Lactose Tolerance or any similar topic only for you Order Now Until fairly recently it was considered normal by Western medicine that in older children and adults the activity of lactase was maintained. We now know that this is the rule among west Europeans and their descendants in other countries. In many other populations the continuation of lactase excretion in older children and adults is virtually absent, leading to lactose intolerance (Dobzhansky et al., 1997). Lactose intolerance is manifested by diarrhea, abdominal pain, and flatulence after consumption of, let us say, half a liter of cow’s milk (Braly, 1992). This holds for many East Asian groups, Melanesians, Native Americans and for most Africans. Groups of nomadic pastoralists in Africa, such as the Fulani, form a notable exception with high prevalence of lactose tolerance. In southern Europe and in certain regions of India intermediate values (from 30 percent to 70 percent) are found lactose tolerance, a biological, genetic adaptation that is commonly found in populations with a long history of dairying (www.vegsource.com). Populations with this genetic trait have the ability to digest lactose, a sugar found in milk. The intestinal enzyme lactase breaks down lactose into simpler sugars that can be absorbed and metabolized as a source of energy. Lactose also plays a part in the absorption of the calcium in milk. This is especially important when Vitamin D deficiency is present ( Durham 1991:226-228). Durham (1991) has pointed out that the full story is more complicated than was originally supposed, since it involves calcium as well as lactose absorption. Nevertheless, the result is the same. Today, between 70 and 100 per cent of human adults whose ancestors came from long-term dairy-farming areas are lactose-tolerant, whereas the great majority of those who stem from non-dairy-farming areas remain lactose-intolerant. This differentiation must have occurred within the last 10,000 years, and must have been induced by human phenotypes changing their own environments. When the body is functioning normally, lactase breaks down lactose into two simple sugars, glucose and galactose, which are used by the body. But when there is a lack of sufficient lactase, the unabsorbed lactose migrates to the colon, where it becomes fermented by intestinal bacteria and causes gastrointestinal problems. In most humans, lactase activity disappears after infancy. That is, they become more or less lactose intolerant after they are weaned. Although they may be able to drink a small glass of milk without much trouble, if they drink large amounts the undigested lactose gives them diarrhea, bloating, and gas. Even though they do not absorb the lactose in milk as an energy source, they may be able to make use of the protein, calcium, and fat in milk, if they drink small enough amounts to avoid distress and the nutritional losses incurred with diarrhea. Alternately, cultural adaptations such as making cheese or yogurt reduce the lactose content. Presumably, the reason lactose intolerance occurs early in life has to do with the process of weaning. Some children are genetically programmed to stop being able to handle milk once they pass the age of breastfeeding. Although there is no perfect correlation the relationship between lactose tolerance in adults and animal husbandry is striking. Two explanations have been suggested, one cultural, and the other referring to physical qualities of the environment (Flatz Rotthauwe, 1977). In the cultural explanation it is postulated that the consumption of milk, because of its nutritional value in proteins, should give a selection advantage. Once there were a few individuals who can tolerate milk, this trait could slowly spread through the population over a large number of generations. The fact that there are cattle farming populations with a low frequency of tolerance weakens this hypothesis. In addition, when milk has fermented it is low in lactose content and is digestible in the absence of lactase in the consumer’s intestinal tract. The second hypothesis postulates an advantage of lactose tolerance in areas with relatively little ultraviolet sunlight, such as northern Europe. Sunlight plays a role in the production of vitamin D which is needed for calcium metabolism. A too low level of vitamin D leads to rickets, a bone disease. It has been suggested that lactose is an alternative substance to vitamin D in the metabolism of calcium. Another version of this hypothesis bears on the direct absorption of vitamin D contained in milk and milk products. In practical terms, knowledge of lactose tolerance and intolerance is important when proposing food aid programs. Knowing that milk can cause digestive problems helps us understand why recipients of powdered milk as emergency aid have used the milk to whitewash their buildings and have even accused aid programs of being U.S. plots to poison them ( Lerner and Libby 1976:327). Health educators also need to be cautious about over-promoting milk products to ethnic groups, such as Asian Americans, who do not tolerate them well. In evolutionary terms, farming is quite recent on the human scene, and most of the adaptations to it have been cultural rather than genetic. Lactose tolerance is particularly interesting because it shows the coevolutionary interaction between biological and cultural adaptation to the farming way of life. References Attwood, Charles R.

Glass Menagerie Symbolism of the unicorn Essay Example For Students

Glass Menagerie Symbolism of the unicorn Essay The symbolism of the unicorn has two very different meanings. One of the symbols is happiness and love. The other one symbols sadness and hatred. You first come into contact with the unicorn when Jim sees it. This is where the first symbolism comes into place. Once Laura starts to talk about it you can sense a feeling of happiness once they really get into their conversation. They start to talk about there past, which included Blue Roses. Once Jim called Emily Meisenbach a kraut-head, Laura knew there could definitely be something between them two. Jim had been telling Laura to have more confidence and to dont think of yourself to be crippled because you arent. You are beautiful. Sparks are really flying until Jim hears some music from the Paradise Dance Hall across the ally and asks Laura to dance. This is where the second symbolism comes into place. As they start to dance Jim hits a table where the unicorn was put. The horn of the unicorn broke off. Jim felt so bad that he told her he should be going. Laura asked when will you come back. Thats when it all fell apart. Jim told Laura that he was going steady with another girl called Betty. Laura was shocked, but didnt want to say anything. Anything that was between Jim and Laura was gone. Nothing was left. Jim left after telling Amanda and thats how the play ended. As you can see, the unicorn played an important role in the play even though it didnt seem as though it would. This is a very well put deception by Tennessee Williams showing his greatness in the art of play writing.
