CHAPTER 3 Exercises 3.6 What are the differences among short-term, medium term, and long-term scheduling? Answer: The short-term scheduler selects from the ready processes the next process to run and gives it the CPU. The long-term scheduler selects from the pool of processes that are waiting on disk and loads the selected processes into memory. These processes have not yet begun their execution. The medium-term scheduler takes processes that are currently in memory and selects those to be swapped out to disk. These processes will be swapped back in at a later point. This is done to improve process mix or because of memory requirements like overcommitted and needs to free up memory. A primary difference is in the frequency†¦show more content†¦Describe the undesirable circumstances that could arise from not enforcing either the at most once or exactly once semantics. Describe possible uses for a mechanism that had neither of these guarantees. Answer: If an RPC mechanism could not support either the â€Å"at most once† or â€Å"at least once† semantics, then the RPC server cannot guarantee that a remote procedure will not be invoked multiple occurrences. Consider if a remote procedure were withdrawing money from a bank account on a system that did not support these semantics. It is possible that a single invocation of the remote procedure might lead to multiple withdrawals on the server. For a system to support either of these semantics generally requires the server maintain some form of client state such as the timestamp described in the text. If a system were unable to support either of these semantics, then such a system could only safely provide remote procedures that do not alter data or provide time-sensitive results. Using our bank account as an example, we certainly require â€Å"at most once† or â€Å"at least once† semantics for performing a withdrawal or deposit.

Allusions in Brave New World - 1665 Words

Henry Ford served as the inventor for the assembly line. He believed that the idea of independently manufacturing products was too inefficient and cultivated the idea to move the product instead of the people building it. Ford also pioneered technological research in developing products. Ford served as the turning point for technology; introducing and utilizing break-through ideas. Not only did he change how automobiles were manufactured, he changed the way people thought about technology. He made new technologies readily accessible and set the standard for the 20th century. In Aldous Huxley’s Brave New World, Huxley makes Ford the center-point for why the new society was created, the old one was un-happy and inefficient. Replacing God†¦show more content†¦He theorized that the U.S. economy was heavily inefficient and as a result was beginning to slow down. He instituted many new government policies that were built upon this idea. Brave New World demonstrates this eff iciency policy into the society’s main economy. The government controls most enterprises and believes that inefficiencies would slow down the economy. Automation and technology are utilized whenever possible. 8. Leon Trotsky was a Russian communist leader in the early 20th century. His beliefs, called Trotskyism, stated that the working class should have supreme power in government control. Brave New World implements Trotsky’s ideas through social classification with a cast system. Although there is a working class and wealthy class, the majority are working class members. Socialism is also used throughout Brave New World by the distribution of wealth and control. 9. Charles Darwin was the father of evolution and natural selection. Darwin brought about the idea of genetic evolution by theorizing that only the strongest in a population will survive and be able to carry on their genes. Brave New World takes on these ideas by utilizing genetic engineering to ensure that the society members have the best genes and have few DNA imperfections. This ensures that the members of a class will not be able to become stronger than the high class. It also ensures a broad single identity amongst a class’s members.Show MoreRelatedEssay on Brave New World-Allusions1337 Words   |  6 PagesAllusions to the Brave New World 1.

ECONOMIC SYSTEMS ASSIGNMENT Essay Canada:The Government of Canada is a Federal Parliamentary Democracy and a member of the Common Wealth. The Prime Minister of Canada is the Honorable Jean Chretien. The Deputy Prime Minister is Sheila Copps and the Governor General is Romeo LeBlanc. There are five major political parties in Canada they are; the Progressive Conservatives, the Liberal Party, New Democratic Party, the Reform Party, and the Bloc Quebecois. The GNP per capita (1991) was $19,934 (in millions). The annual GNP growth was 3.4%. The amount of GNP for defence was 2.2%. The majority of workers in Canada are in the Service field (73%), Industry has 23% of the workers, and Agriculture has the remaining 4% of the labour workforce. Canada has an unemployment rate of 9.5% and an inflation rate of 2.3%. Canadas top three natural resources are Nickel, Zinc and Copper. Canadas top three agricultural products include Wheat, Barley, and Corn. The three major Canadian industries are automobile manufacturing, lumber industry, and petroleum products. Canada has a healthy trading market with major partners such as the United States, Mexico, and Japan. The top three imported products are vehicles, foodstuffs, and animal feed, while the three major exports include vehicles, petroleum products and natural gas. Canadas exports vastly outweigh their imports.The balance of trade is $9,823,000,000 (more exports than imports). Canadas economy is a market economy based on free enterprise and the ideology of capitalism. As a Canadian citizen you are free to buy and sell as you please on the open market, so long as you are within the law. Since Canada is a democratic state we are guaranteed these rights and freedoms. Canada has a very efficient economy. We have an unemployment rate of only 9.5% and a reasonably small inflation rate. Canada has been rated as one of the best countries in the world Coincidence?Niger:The Government in Niger is a republic in which there is a President and a Prime Minister. The President of the Republic of Niger is Mahamane Ousmane. The Prime Minister is Hama Amadou. There are five major political parties. They are; The National Movement for the Developing Society, The Democratic and Social Convention, Nigerian Party for Democracy and Socialism, The Nigerian Alliance for Democracy and Progress, and The Union of Progressive Patriots and Democrats. Niger has a Gross National Product per capita of $550 (in millions). There is an annual GNP growth of 1.4%, 0.1% more then the allotted funds for defence. The majority of the labour force works in agriculture (45%), the service field represents 39% of the workers, and the remaining 16% are employed in the industrial field, which is declining at a rate of 2.7% per year. Niger relies on its three top natural resources, which are; Uranium, Coal, and Iron/Ore. The three main agricultural products are; Millet, Sorgum, and Pulses. Nigers major industries are based in the fields of Cement, Beverages, and Beer. Niger is a country in which there are many more imports than exports. The three main imports are; foodstuffs, cereal, and sugar, while the three major exports are; Uranium, Foodstuffs, and Livestock. Niger is one of the worlds poorest countries. Their economy is centered on subsistence farming. Uranium, their major export through the 1970s and 1980s, revenue has dropped by 50% between 1983 and 1990 (end of cold war). Nigers balance of trade is $-58,000,000 and they carry a debt of $1.2 billion. One U.S. dollar is equal to $529 of their currency the Communaute Financiere Africane Francs. Niger has a traditional economy similar to many other 3rd World Nations. Recent studies would suggest that 4/5 of their major exports relate to livestock and agriculture (hides and skins, vegetables). Their economy is very inefficient because of the fact that they import more than they export, although that is not always negative, a third world nation which remains in debt will never prosper. .u741697f1b95ba843d9415252f879463d , .u741697f1b95ba843d9415252f879463d .postImageUrl , .u741697f1b95ba843d9415252f879463d .centered-text-area { min-height: 80px; position: relative; } .u741697f1b95ba843d9415252f879463d , .u741697f1b95ba843d9415252f879463d:hover , .u741697f1b95ba843d9415252f879463d:visited , .u741697f1b95ba843d9415252f879463d:active { border:0!important; } .u741697f1b95ba843d9415252f879463d .clearfix:after { content: ""; display: table; clear: both; } .u741697f1b95ba843d9415252f879463d { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u741697f1b95ba843d9415252f879463d:active , .u741697f1b95ba843d9415252f879463d:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u741697f1b95ba843d9415252f879463d .centered-text-area { width: 100%; position: relative ; } .u741697f1b95ba843d9415252f879463d .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u741697f1b95ba843d9415252f879463d .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u741697f1b95ba843d9415252f879463d .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u741697f1b95ba843d9415252f879463d:hover .ctaButton { background-color: #34495E!important; } .u741697f1b95ba843d9415252f879463d .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u741697f1b95ba843d9415252f879463d .u741697f1b95ba843d9415252f879463d-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u741697f1b95ba843d9415252f879463d:after { content: ""; display: block; clear: both; } READ: Lebanon: A Globe-trotters Guide EssayJapan:Japan is a Constitutional Monarchy with a figure head of Emperor Akihito (son of Hirohito).
