Howard Zinn on Democratic Education Essay
Upon reading the book, Howard Zinn on Democratic Education, I felt a lot of questions I had regarding education was answered. I had always regarded education as something liberating, something that would be able to teach students how to become enlightened. That is why I read a lot of books. But regarding my schooling, I questioned why we are loaded with so much homework and tests, we end up not deeply understanding anything at all, because there is no time to process all the information. It is as if our schooling stunts our educational growth. Yet, the irony of it is they teach us so much facts of how, where, when, who, and what, but I had this nagging suspicion that teachers were hiding vital information from us. I did not know what exactly, but I always felt something was missing because I could not connect what I learned in school to what was happening to our country as I watched the news. It was as if there was a missing link, a key that would make everything make sense. Yet, as the years in the academe passed, I encountered no such link. Until now. It was as if my youthful objections found validation. I had always felt that my schooling lacked feeling. All these hard facts were discussed as if they did not involve people. We really never knew, through history, how terror felt when planes during the World War II flew overhead, or triumph when the war was declared over. It is not anybodyââ¬â¢s fault. I think, history cannot be studied; it has to be lived. Although in my opinion, it can be remedied. Instead of sitting in classrooms all day, reciting facts, we should focus on gathering our own information regarding events. This does not mean reading even unassigned readings. I have always thought that people are not foolish. Each individual has a unique story, if we only care to listen. We should experience learning, and this can only be done by going out of the classroom, and learning from living people. After all, the papers our books are made up of were once living things too. The critical question now is, what now? Now that we possess such knowledge, what must we do with it? Knowledge that is not followed by action is a dead thing. We could start through transforming our own classroom, if we are to teach, or even in our own homes. Drop-out rates are not surprising due to the fact that so few kids feel remotely connected to their schooling. If we involve these kids, make them see that it is also their classmatesââ¬â¢ loss if they do not attend classes, they can be pulled back into the academe. To do this, they must be able to feel that they can contribute something to the discussion, whether it be a question or an opinion. We must impress upon our minds that there are no right or wrong questions or opinions. Each comes from a different background (hence a different culture), so we must be patient and understanding. We must also find tangent points; we must connect the academe with their lives. We must do away with the notion that scholars have ivory towers. We must reconnect. Because this is what education does. It reconnects people with other people. It reconnects people with ideas. It reconnects people with opportunities. It reconnects people with hope. If all the attendants in a classroom participate freely and energetically, actively molding their curriculum to suit their individual needs, we will have captured the essence of a democratic education. Through this, we will have a truly democratic country. References Schugurensky, D. (2005). Howard Zinn on Democratic Education. International Journal of Citizenship and Teacher Education , 1, 99-100.

Roles Of Botanical Garden In Plant Conservation Environmental Sciences Essay
The subject for this essay is the functions of botanical garden in works preservation. The essay will be divided into four chief parts. The first portion discuss about the botanical garden. This portion will include the debut, history and development, web and map of botanical garden. Second portion will explicate the importance of works preservation and the planetary scheme for works preservation. The 3rd portion is the function of botanical garden in works preservation. The 4th portion will be the illustration of botanical garden in Malaysia and its functions in works preservation. The last portion will be the decision of the essay. 2.0 Botanic Gardens 2.1 Introduction Botanic gardens or botanic gardens are by and large well-tended Parkss exposing a broad scope of workss labelled with their botanical names. They may incorporate specializer works aggregations such as cacti and succulent workss, herb gardens, workss from peculiar parts of the universe, and so on ; there may be nurseries, once more with particular aggregations such as tropical workss, alpine workss or other alien workss. Botanic gardens are frequently run by universities or other scientific research organisations and frequently have associated herbaria and research programmes in works taxonomy or some other facet of botanical scientific discipline. In rule their function is to keep documented aggregations of life workss for the intents of scientific research, preservation, show and instruction, although this will depend on the resources available and the particular involvements pursued at each peculiar garden.2.2 History and DevelopmentThe beginning of modern botanical gardens can be traced to European mediaeval medicative gardens known as physic gardens, the first of these being founded during the Italian Renaissance in the sixteenth century. This early concern with medicative workss changed in the seventeenth century to an involvement in the new works imports from geographic expeditions outdoors Europe as vegetation bit by bit established its independency from medical specialty. In the eighteenth c entury systems of terminology and categorization were devised by phytologists working in the herbaria and universities associated with the gardens, these systems frequently being displayed in the gardens as educational ââ¬Å" order beds â⬠. With the rapid rise of European imperialism in the late eighteenth century botanic gardens were established in the Torrid Zones and economic vegetation became a focal point with the hub at the Royal Botanic Gardens, Kew, near London. Over the old ages botanical gardens, as cultural and scientific administrations, have responded to the involvements of vegetation and gardening. Nowadays most botanical gardens display a mix of the subjects mentioned and more: holding a strong connexion with the general populace there is the chance to supply visitants with information associating to the environmental issues being faced at the start of the twenty-first century, particularly those associating to works preservation and sustainability.2.3 NetworkWorldwide there are now about 1800 botanical gardens and botanical garden in approximately 150 states ( largely in temperate parts ) of which about 400 are in Europe, 200 in North America, 150 in Russia and an increasing figure in East Asia. These gardens attract about 150 million visitants a twelvemonth so it is barely surprising that many people gained their first exciting debut to the admirations of the works universe in a botanical garden. Historically, botanical gardens exchanged workss through the publication of seed lists. This was a agency of reassigning both workss and information between botanical gardens. This system continues today although the possibility of familial buccaneering and the transmittal of invasive species have received greater attending in recent times. The International Association of Botanic Gardens was formed in 1954 as a world-wide administration affiliated to the International Union of Biological Sciences. More late coordination has besides been provided by Botanic Gardens Conservation International ( BGCI ) which has the mission ââ¬Å" To call up botanic gardens and engage spouses in procuring works diverseness for the wellbeing of people and the planet â⬠. BGCI has over 700 membersA ââ¬â largely botanic gardensA ââ¬â in 118 states and strongly supports the Global scheme for works preservation by bring forthing a scope resources and publications, and by forming international conferences and preservation plans. Communication besides happens regionally. In the United States there is the American Public Gardens Association and in Australasia there is the Botanic Gardens of Australia and New Zealand ( BGANZ ) .2.4 Role and FunctionBotanic gardens have had a altering function throughout history, get downing frequently as medicative gardens for the survey and cultivation of workss with mending belongingss and traveling through many stages including of class as pleasance gardens. But the fact that their aggregations are more or less scientific means they are continually accommodating and functioning the demands of their societies in germinating ways as new challenges face those societies. In current times, they are going cardinal participants in both the preservation of workss and in the instruction of the people who come to see them.A They are besides get downing to play a function in the extenuation of the effects of clime alteration, and could be perfectly critical to the endurance of the planet as they are absolutely placed to assist travel species around and assist ecosystems to accommodate to new climes in different parts.3.0 Plant preservation3.1 ImportancePlants are universally recognized as a critical portion of the universe ââ¬Ës biological diverseness and an indispensable resource for the planet. In add-on to the little figure of harvest workss used for basic nutrient and fibers, many 1000s of wild workss have great economic and cultural importance and potency, supplying nutrient, medical specialty, fuel, vesture and shelter for huge Numberss of people throughout the universe. Plants besides play a cardinal function in keeping the planet ââ¬Ës basic e nvironmental balance and ecosystem stableness, and supply an of import constituent to the home grounds for the universe ââ¬Ës carnal life. At present we do non hold a complete stock list of the workss of the universe, but it is estimated that the entire figure may be in the order of 300,000 species. Many of these species are in danger of extinction, threatened by habitat transmutation, over-exploitation, foreign invasive species, pollution and clime alteration. The disappearing of such critical and big sums of biodiversity poses one of the greatest challenges for the universe community: to hold the devastation of the works diverseness that is so indispensable to run into the present and future demands of world. Plant preservation, long the hapless relation of the preservation universe, has started to come into its ain since the rise of preservation biological science as a recognized subject in the 1980s. Plant preservation, and the heritage value of exceeding historic landscapes, was treated with a turning sense of urgency. Specialist gardens were sometimes given a separate or bordering site, to expose native and autochthonal workss.3.2 Off-site works preservationOff-site preservation is the preservation of workss off from their countries of natural happening. The term ex situ is often used to depict the off-site preservation. Off-site preservation non merely include turning the workss in botanic gardens, the construct extends every bit good to field cistron Bankss, clonal aggregations, and source plasma Bankss where propagating tissues and seeds are preserved for turning in the hereafter. Off-site preservation can affect a scope of works parts-the whole works, seed, other tissues, or famil ial stuff in civilization. Whole, populating workss have peculiar value for preservation and will go on to be a major concern of off-site preservation. But conserving whole workss is non simple. To capture the scope of familial fluctuation, such aggregations require big figure of workss ; these are expensive to set up and keep. If the workss are annuals, they will necessitate seasonal reproduction. Outside their natural habitat some workss may necessitate manus pollenation and particular intervention of fruit and seeds to guarantee sprouting. It is fortunate that bettering engineering is doing storage as seeds, seedlings, rootstocks, tissues in civilization, and even DNA an option for many workss.3.3 Global Strategy for Plant ConservationThe entry point for the scheme is works preservation ; other facets such as sustainable usage, benefit-sharing and capacity edifice are besides included. The Strategy provides an advanced model for actions at planetary, regional, national and local degrees. The scheme is suppo rted by a broad scope of organisations and establishments ââ¬â authoritiess, intergovernmental organisations, preservation and research organisations ( such as protected-area direction boards, botanic gardens, and cistron Bankss ) , universities, research institutes, nongovernmental organisations and their webs, and the private sector. The most advanced component of the Strategy is the inclusion of 16 outcome-orientated marks, aimed at accomplishing a series of mensurable ends by 2010.3.3.1 AimsThe ultimate and long-run aim of the Global Strategy for Plant Conservation is to hold the current and continuing loss of works diverseness. The Strategy will supply model to ease harmoniousness between bing enterprises aimed at works preservation, to place spreads where new enterprises are required, and to advance mobilisation of the necessary resources. The Strategy will be a tool to heighten the ecosystem attack to the preservation and sustainable usage of biodiversity and concentrate on the critical function of workss in the construction and operation of ecological system and assure proviso of the goods and services such systems provide.4.0 Role of Botanical Gardens in Plant ConservationBotanic gardens have jointly accumulated centuries of resources and expertness that now means they play a cardinal function in works preservation. Many of these activities contribute to ex situHYPERLINK ââ¬Å" hypertext transfer protocol: //www.bgci.org/ourwork/ex_situ/ â⬠preservation, but botanic gardens besides play an of import function in in situHYPERLINK ââ¬Å" hypertext transfer protocol: //www.bgci.org/ourwork/Ecosystems/ â⬠preservation Gardening and cultivation accomplishments allow us to turn workss that might be lost in nature, which means their workss ââ¬Ë diverseness can be conserved in the gardens, but besides allows us to see Restoration and rehabilitation of debauched home grounds. Populating aggregations of workss cod species under assorted groupings, to keep a life shop of familial diverseness that can back up many activities in preservation and research. Seed Bankss and aggregations of life workss allow species to be safeguarded. Plants must be carefully collected stored to guarantee maximal familial diverseness is retained, and much research is required to find the best manner of hive awaying each species. This is the preservation of works diverseness in situ, and botanic gardens are cardinal to this scheme ââ¬Ës capacity and success.. Research and development into works taxonomy and genetic sciences, phytochemistry, utile belongingss, informing choice of workss that can defy degraded and altering environments ( particularly of import in face of the menaces posed by clime alteration ) . Education is a strength of botanic gardens that allows them to pass on the importance of conserving workss, making out to diverse audiences, and besides to pass on how this may be achieved. Associating workss with the wellbeing of people, and besides assisting conserve autochthonal and local cognition, to promote the sustainable usage of works resources for the benefit of all, as portion of sustainable development. The preservation of works diverseness is critical for sustainable development and botanic gardens are playing a cardinal function as Centres of preservation action. Gardens maintain a broad scope of species as life workss, in seed Bankss and tissue civilization ; harmonizing to appraisal of BGCI, there are likely over 80,000 species in cultivation in botanic gardens of the current estimation of 270,000 known works species in the universe. Botanic gardens contain aggregations of workss for instruction, scientific intents and show ; they can be: Taxonomically-based ââ¬â aggregations of a peculiar household, genus or group of cultivars ; Collections of native workss ; Plants which portion a common geographical or ecological beginning such as Mediterranean, desert or alpine ; Wild relations or cultivars of utile species such as medicative, aromatic or textile workss ; Shared wont or life signifier such as an grove, botanical garden or lush aggregation. Botanic gardens besides have of import preservation aggregations peculiarly of rare and threatened workss. Harmonizing to the IUCN Red List of threatened workss 34,000 taxa are considered globally threatened with extinction. Presently, over 10,000 threatened species, about a 3rd, are in botanic garden cultivation. These workss contribute to species recovery programmes and supply long-run backup aggregations. Botanic gardens undertake research ââ¬â from works taxonomy, ecology to engendering systems. With their expertness in gardening, botanic gardens develop extension and cultivation methods for workss which have ne'er been in cultivation. All these countries are indispensable for species recovery programmes and reintroduction of workss into the wild, such as developing techniques to re-introduce the Dragon Trees into the natural state. A major cause of biodiversity loss is the over-collection of wild workss for gardening, medical specialty and nutrient. Bringing workss into cultivation can take the force per unit area off the wild populations, and besides back up supports by bring forthing income and promote trade Botanic gardens besides manage protected countries within and outside their garden to advance biodiversity. These ecosystems such as woods, shrub land, catchment countries, and coastal countries provide indispensable services from the coevals of H2O, cycling of foods and refilling of dirt birthrate and bar of eroding which are critical to the supports of all people. One of the major causes of species decline is invasive foreigner species which threaten workss, works communities and ecosystems. Botanic gardens with their accomplishments in designation and gardening proctor invasive species and work locally and nationally to reconstruct home grounds that are of import for diverseness. Botanic gardens work with their local communities and visitants on instruction and environmental preservation programmes which promote environmental consciousness and sustainable life. Globally, botanic gardens receive more than 200 million visitants a twelvemonth. Further, botanic gardens are cardinal establishments working with their authoritiess and other administrations on cardinal policies, national biodiversity schemes and action programs.5.0 Botanic Garden in Malaysia ââ¬â Rimba Ilmu5.1 IntroductionRimba Ilmu is a tropical botanical garden, set up in the University of Malaya campus in Kuala Lumpur, Malaysia. It is modelled after a rain forest garden construct instead than a formal flower garden. It emphasises the vegetation of the Malaysian and Indonesian part. Together with the life aggregations of over 1,600 species, the Rimba Ilmu besides houses the University of Malaya herbarium ( acronym KLU ) and has its ain Environmental Education Programme. The Rimba Ilmu is a member of the Botanic Gardens Conservation International ( BGCI ) and the South East Asia Botanic Gardens Network.A Rimba Ilmu means ââ¬Å" The Forest of Knowledge â⬠in the Malay linguistic communication. The garden, established in 1974, occupies an country of 80 hectares. It is partially buffered by old gum elastic plantings and the life aggregations, largely from Malaysia, are one of the most of import biological conservatories in Malaysia. There are besides works species from other parts of tropical Asia, the Pacific islands, Australia, South America, Africa and Madagascar.A Rimba Ilmu ââ¬Ës mission is to bring forth and advance consciousness and cognition of tropical works life and its environment, ecology and preservation through the development and direction of installations and activities appropriate to its map in a university located within Malaysia ââ¬Ës most developed and populated landscape. The Herbarium ( a mention library of preserved works specimens ) is Malaysia ââ¬Ës largest university aggregation incorporating some 63,000 accessions. In the Garden, there are several chief show aggregations, including medicative workss, thenars, and the citrous fruit and citroid aggregation. The Conservatory of Rare Plants and Orchids, opened in 2000, and the Fernery, with seting constitutions made over several old ages and commissioned in 2003, are accessible merely to particular group visits and research contacts, and a new bambusetum ( populating aggregation of bamboos ) was completed at the terminal of 2003 and by and large accessible to the populace. There is besides a little research aggregation of bananas. A high spot in the development of the Rimba Ilmu is the constitution of a particular botanical garden ( populating aggregation of trees ) get downing in 2001 as the ground tackle for our ââ¬Å" Millenium Forest â⬠undertaking, which seeks to prosecute friends and concerned parties in set uping biologically diverse forest plantings in doing a new wood within the metropolis of Kuala Lumpur.A Besides holding a general aggregation of species from a assortment of works households selected for instruction, Rimba Ilmu is besides developing assorted particular aggregations runing from those of medicative workss, wild orchids, thenars, pandan, tropical fruit trees, gingers, aquatic workss, wild citrous fruit relations to rare and endangered workss in demand of preservation.5.2 Role in Plant ConservationRimba Ilmu is an of import depository for many types of workss, including preservation aggregations of rare and endangered workss, and particular aggregations of the utile workss ( such as citrous fruits and starch thenar ) and their wild relations. In 2001, two other particular aggregations, bamboos ( sponsored by the International Plant Genetic Resources Institute ) and bananas ( anchored by one of the university ââ¬Ës research groups in banana cytology ) , were besides begun. Over 2004-5, with the aid of DHL and affecting their employees, a particular aggregation of Malayan wood trees has besides been established. Outside of the Rimba Ilmu, it may be really hard to detect so many different species of some groups, and the home grounds of some of these workss may hold already been altered or damaged. Conservation besides involves public consciousness, and visitants are foremost treated to a lasting exhibition on Rain Forests when they start to acquire familiar with the Garden.A6.0 DecisionBotanic gardens maintain a broad scope of species as life workss, in seed Bankss and tissue civilization. Therefore, botanic gardens contain aggregations of workss for instruction, scientific intents and show. In decision, the botanical garden drama an of import function as the ex situ preservation for works and besides in situ preservation site. The preservation of works diverseness is critical for sustainable development and botanic gardens are playing a cardinal function as Centres of preservation action.

Cultural assessment - Essay Example However, this has changed over time and tremendous growth of this tribe occurred. Hawaiian language is the forms part of the native language but many have abandoned it for English. Education has a high place in this tribe with Hawaiian children receiving public education like many of US citizens. In addition, there exists special education system where Hawaiian children learn using their native language. This have helped improve the level of literacy in this tribe. Hawaiians belief that health is a holistic issue and thus should be taken seriously. They use the term Lokahi to express their understanding of health. Lokahi means balance or harmony. In this culture, a person is healthy when their physical, mental, and spiritual parts are peaceful. Healing can only occur traditionally after putting things straight in the spiritual realm. They believe that illnesses affect the entire family, which calls for consulting every member of the family on the treatment plans (ââ¬Å"Stanford,â⬠2012). Hawaiians have adopted poor eating habits from the westerners eating food high in fat and low in complex carbohydrates. Therefore, diabetes is a common disease to Hawaiians with a prevalence rate of 69.3%. A return to the old eating habits can help lower this prevalence. Hawaiian islanders grow traditional foodstuffs like taro, and sweet potatoes that are quite nutritious (Roger, 2011). Apart from obesity, other diseases that are catching up on this popu lation include cardiovascular diseases due to change from fishing to canned fish (ââ¬Å"Stanford,â⬠2012). Hawaiians traditional healing practices include massage, tacking some herbs, prayer and conflict resolution. These beliefs have hindered Hawaiians from accessing helpful medical treatments. There are tremendous changes in the way Hawaiians seek medical treatments nowadays. However, Hawaiians

How did race, class and gender intersect in the imperial enterprise Essay
How did race, class and gender intersect in the imperial enterprise - Essay Example The trendy of masculinity based on professionalism, rhetoric of militarism, as well as elitism enhanced a set of attitudes and personalities to fit in the structure of imperial legitimacy in conjunction with racial dominance. Moralists at the fin-de-siecle hitherto supporters of a specific brand of inflexible gender concepts of manliness responsible for the perpetuation of a society that had a hierarchical framework. The spread of rigid gender ideologies worked to maintain power and privilege both abroad for instance in South Africa and at home. The socio-sexual framework during the Victorian Britain regime came of the intersection through race, gender, and class and in the process informed the outlined power structures that acted on behalf of the nexus of the bigger political enterprises. In the end, the rise of masculine culture in an inflated manner happened simultaneously with the exposure of the proverbial Achilles Heel for Britain. These were the vulnerabilities of the colonial mastery resulting from strong and brave claims for the power of the British. The British officers acted as competitive, aggressive, and powerful figures (Perry, 2001, p. 33). This is the reason various forums continue to debate on national identity and the imperial rule associated with two reinforcing ideologies acting in a mutually inclusive way. The concepts in the discourse are the Empire and dominant masculinity. Scholars explain the symbiotic relationship between race, gender, and class born out of fear concerning the decline of the British superior race. A series of movies, a huge quantity of literature, and a wide range of works of art often put into perspective colonization and the entire process of forming empires among them the British Imperial enterprises as male dominated adventure stories. The imperial enterprises entailed maleness (Stoddard, 2012, p. 89). However, according to the historians who studied gender, imperial maleness otherwise referred to as masculinity re quired regular and standardized substantiation and confirmation. Scholars who dwelt on the analysis of the empire found similar characteristics for the colonial rule that also constantly required confirmation and legitimization due to the permanent fear among the British white that subject in the colonial enterprises would undermine the racial as well as colonial privileges and prestige in addition to power and superiority of the colonial master. The forums of colonial discussions on gender appeared among the spaces of manifesting the instability and power structures of the empires were most visible. It is important to identify that competing interests of femininity and masculinity called maleness were significant to the normal order of the colonial master (Kent, 1987, p. 87).Ã However, it is not possible to comprehend them in isolation. Any analysis of the two in addition to race and class requires an overall undertaking of their history put into their contextual perspectives. Th e society constructed gender, race, and class in interplay with other categories as well themselves. They include religion, ethnicity, as well as sexuality. The intersection resulted in creating racial, sexual, and national hierarchies that provided the challenge or stabilized the imperial rule during the nineteenth and twentieth century. They intersection also offers challenge to the scholars of history to think and study
Change and Continuity in Contemporary Business Essay - 1
Change and Continuity in Contemporary Business - Essay Example A smart enterprise would keep a close eye on the changes in competitive advantages of the organization and realign their strategies & policies such that the business revenues and market share can be sustained. Such enterprises grow globally by carefully choosing their countries/regions of expansion after analysis of the external & internal factors that can drive the competitive advantages of the company in those geographies. Ford Motors is one such smart enterprise that has been changing their strategies & policies to sustain the challenges posed by the local factors in a country by not only globalizing rapidly but also changing their strategies pertaining to their regions of operations. This report presents the internal and external factors and the corresponding responses by Ford Motors to sustain as well as grow their business globally. Balanced Score Card System developed by Kaplan and Norton via their book "Balanced Score-Card - Translating Strategy into Action" published in 1996 (Source: http://www.balancedscorecard.org/BSCResources/AbouttheBalancedScorecard/tabid/55/Default.aspx) Ford Motors was incorporated by Henry Ford in 1903 in Dearborn, Michigan, USA. Henry Ford is known to have adapted practices that were not popular in those days - like, doubling per day wages and reducing the shifts from 9 hours to 8 hours. It was the worker friendly policies that boosted productivity of Ford much ahead of their competition. Ford is known for their methods of large scale car manufacturing and management of huge workforces globally. In 1911, Henry Ford established the first production unit outside USA in the UK by converting a tram works at Trafford Park that is in south of Manchester. In 1920, after the Second World War, the famous Dagenham facility was established that formed the base for launch of Ford Motor Company Limited (UK) in 1929 that was the hub of the European Ford organization (till the time Ford Motor Company Europe was established much later in 1967). In 1971 Ford combined the US, Canadian and Mexican operations together and established the North Ameri can Automotive Operations. The Dagenham facility was one of the most productive in assembly plant in entire Europe which, however, was closed in 2001 amidst some local factors that reduced the economy advantages of Ford manufacturing in Britain while the manufacturing in Germany and other parts of Europe was much more economical. The primary reasons for Ford manufacturing closure in Dagenham was the insurgence of shop-floor militants that developed a powerbase disrupting production by launching almost continuous Guerrilla warfare while Germany offered much more peaceful and strike free industrialization proposition. Moreover, Ford Motor Company

Memory Management Essay Example | Topics and Well Written Essays - 1250 words
Memory Management - Essay Example The partitioning that is done in memory for its allocation can be fixed. There are two possible methods whereby which queues may be used to bring processes into the memory for execution. The first method is by using a single queue and the second method I by using multiple queues as shown in the fig. 1. Figure 1 Fixed memory Partitioning. Using multiple queues Using Single Queue Mechanism The first available memory location that is large enough to hold the process is allocated All processes get lined up into a single queue. The partition closest to the process that can hold it is assigned to that process. Advantages Load is balanced. Arrived processes are transferred evenly into all memory partitions. As soon as a memory partition gets free it is assigned to a waiting process. The allocation process is very quick. The allocation process does not waste memory space. Disadvantages Any memory size that may be more than the size of the process gets lost. Moreover the queues of small parti tions are often lined up with several processes while those with larger partitions are often left untouched. The drawback is that even though large sizes of memory are free small processes are not allocated that memory and they stay lined up in the queues of smaller memory sized partitions waiting for their turn to come. A large partition may be wasted on a small job resulting in loss of large amounts of memory. Unbalanced load. Some queues may be empty while others are fully loaded. 2. What is the swapping technique? Why is it needed for multiprogramming environment? Swapping generally means interchanging the contents of two different spaces using a third temporary empty content space. Swapping is used as a memory management technique for multiprogramming environment. For a program to execute it is mandatory to acquire physical memory or main/primary memory. In a uni-processor environment multiple programs can simultaneously be executed by overlapping an I/O of a program with the e xecution of another program. Due to the limited size of physical memory it is very difficult to accommodate all of the required programs in main memory. To accommodate new programs currently running programs are swapped out on the basis of their activity status. For example when a program asks for data from secondary storage, it has to wait for complete input. Meanwhile due to Direct Memory Access the CPU remains available for other programs. The operating system thus swaps out the waiting program with the one that needs to be executed with the CPU. Upon completion of data transfer the earlier program is invoked and swapped into the memory again. This is how swapping works for multiprogramming environment. 3. Discuss the main function(s) of each of the following operating system parts: a) Memory management Unit The Memory Management Unit is said to serve as a buffering agent between the Central Processing Unit and the memory of the system. The functions that are performed by this un it may roughly be categorized into three categories. These are: 1. Operating System Memory Management, 2. Hardware Memory Management and 3. Application Memory Management. Specifically speaking, it translates address from their virtual address format into their physical address format. b) Linker ââ¬Å"Performs the function of linking the libraries to the object code in order to transform the object code into an executable machine.â⬠(cool interview, 2012).
