Assembler, compiler and interpreter

Assembler, compiler and interpreter Assembler 1. An assembler is not equivalent to an interpreter, or compiler, assembly language is a low level language. 2. An assembler is one form of program translation. This is one relationship between assembler, compiler and interpreter. Each assembly language statement directly corresponds to one machine instruction. 3. The Assembler changes Assembly instructions into machine language, whereas a Compiler runs a higher level programming language instructions into Assembly instructions and then those are converted into executable machine language. 4. Accumulated programming languages normally generate lots of lines of Assembly instructions for each program report. 5. An assembler creates object code by changing symbols or substitute names into machine code.One could conclude that Assembly language is not a programming language at all, just guilty by association. Assembly language is nothing more than a shorthand system of writing, machine language, programs using symbols that friendless personality lacking, knuckle dragging WOW players, otherwise known as programmers, can understand. Compiler 1. A compiler converts an entire program written in source code and translates it into object code. 2. A second relationship is that the compiler and interpreter both process source code. 3. A compiler translates source code from a high-level programming language to assembly language/ machine code. A compiler works with what is called higher-levellanguages3rd generation languages, such as Java and C. Typically a person writes source code using an editor in a language such as C, Pascal or C++. The programmer then selects the appropriate compiler for the source code. Interpreter 1. Another relationship is that the interpreter is the step by step version of a compiler. Obviously this takes a lot of time and resources compared to previously compiled program. 2. An interpreter doesnt have to examine the entire program before it can begin executing code. 3. An interpreter is a computer program that takes source code and processes one line at a time. Interpreters translate code one line at time, executing each line as it is translated, Interpreters do generate binary code, but that code is never compiled into one program. Instead, the binary code is interpreted every time the program executes. Nonprocedural Language or Declarative language 1. Non procedural languages say what conditions the answer should match but not how to satisfy them. 2. With nonprocedural language you are stuck with whatever options the program allows 3. A Nonprocedural language example is Excels style of programming. Considered a 4th generation language also called declarative language. Structured Software 1. Structured software is for the most part fitting for applications that have many independent functions that do not correlate to a great extent. 2. This technique is not very fitting where data is going to change as opposed to the function 3. Structured programming is primarily a way of breaking a problem into routines. It gives emphasis to functionality without stressing the data. The most likely application is for problems where significant functionality is probably going to change rather than the data. At the point at which you have recognized the object boundary and you start writing the code to support them within the sections; it is common to change to a structured design. Structured software may fail on projects with 100,000 lines of source code or more. Object-Oriented Software 1. Object-oriented software makes it easier to develop, debug, reuse, and maintain software than is possible with other programming languages. 2. Object orientation takes the concepts of structured programming and puts it in 4-wheel drive. Object oriented software is equivalent to combining the usability of the fork and the food moving abilities of the spoon and comes up with a Spork. 3. object-oriented software is a computer program using object-oriented programming that revolves around the concept of an object. Object-oriented languages make it easier to reuse, and maintain software than is possible with other languages. Now, instead of data structures and separate program structures, both data and program elements are combined into one structure called an object. The object data essentials are called attributes, while the object program essentials are called methods. Together, attributes and methods are called the objects members. Usually, an objects methods are the only programs able to operate on the objects attributes. The easiest way to understand this is an analogy. Pretend you are building a house. With earlier generation programming, each and every component was written and designed for an exact function or result. This would be the same as making kitchen cabinets out of the lumber at the house piece by piece. Every house you built would require making cabinets at the location, out of the lumber that was supplied for the house. The sanity saving technique of object-oriented programming follows the logic of making a kitchen cabinet as a module. In programming terms, these cabinet modules are objects. This type of programming makes the effort much more efficient by allowing instructions from one program to be integrated into another. If for example a circle needs drawn on the screen you can use a circle object from another program. If the circle needs to be modified then a small amount of programming may be needed, but you no longer have to build it from scratch.

The Transformation of Sydney Carton in A Tale of Two Cities :: Tale Two Cities Essays

The Transformation of Sydney Carton in A Tale of Two Cities         Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   In Charles Dickens' novel A Tale Of Two Cities, Sydney Carton is a man of several distinct characteristics.   Carton is shown originally to be a frustrated alcoholic, but then turns out to be a very noble and genuine man. Sydney Carton is also shown in the novel to be somewhat immature in his actions and thoughts.      Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Throughout the book, Sydney Carton does not always act or seem like he is the age that he is.   He is depicted in the novel to be middle-age, perhaps in his mid-forties, yet several times he shows some very immature actions and feelings.   One example is his feelings for Lucie Manette.   Even after Lucie is married to Charles Darnay, whom she loves, Sydney refuses to give up his love for her.   For someone in his mid-forties, this is somewhat an immature action. Had he been more mature, he might have forgotten about Lucie when she was married and found someone else.   Another perhaps less important but very noticeable example is his appearance.   He didn't seem to care what people really thought about him or the way he was dressed, and remained very calm and relaxed, maybe even carefree, most of the time he was in court.   This also gives Sydney Carton an immature appearance in the novel.      Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   At the beginning of the story and a large part of the novel, Sydney Carton is shown to be a very arrogant, frustrated man with a drinking problem. Several times in the novel he indulged in his drinking to the point of becoming drunk or close to it.   Many times that he is seen, he is drinking wine or has a flask of liquor in his hand.   This may keep him calm or help him to remain composed in the court, but it becomes more to the point of being a necessity or habit.   Also, his drinking causes him to be loose with his tongue when he is with Charles Darnay after the trial, which makes Charles angry with him.   This behavior was very ill-mannered and could have been prevented to give Sydney Carton a better appearance and attitude.      Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Later in the novel, towards the end, Sydney seems to change his

do children owe their parents? :: essays research papers

There is a question that I have been thinking of: â€Å"Do I owe something to my mom and dad†? – Who knows†¦ Sometimes we might think that we owe them a lot, but then other times we might think â€Å"Why should I do something for them? I have my own life. I have lots of to do without taking care of my folks†. But then again, how can I leave them in trouble when they are the same bloods? I look like them and most importantly I love them. It depends on the relationship between parents and kids when deciding if we owe them something or not. Children who felt loved, had lots of attention from a mother and father growing up will try to treat them the same way, instinctively paying back good for good. In families without strong connections, kids will very simply forget about their parent’s existence. They may believe that no one asked their parents to have them. No one asked them if they wanted to be born they had no choice. Two adults wanted to have kids and they had them. It was their choice to be responsible and raise the next generation. Then if look at the nature, you would not find creatures who would do something to support their parents after they grew up. We are just one of many creatures in this universe. Why it should be different for us? Humans are most developed creatures on the earth with feelings, lots of knowledge, procreating their kind, taking care of each other. So isn’t it most important to look after the people who are close to you? And only then look after the others? Why do we forget that sometimes?.. Parents are the first people who deserve your attention. Through the years they put so much effort and passion the way they can, to protect us from bad. We know that mom and dad will be next to us even if we get in trouble or lose everything. They still will be the ones to help us as much as they can. They will find space in their home for us to stay. For this reason we should be so thankful to them and pay for it in advance. However there are big differences between cultures and countries. For example in my country, Lithuania, parents are taking care on their kids until â€Å"babies† can really support themselves.

pauls case Essay example -- essays research papers

Paul’s Case Paul's Case is about a young, Calvinist man who did not feel that he belonged in his life. He lived on Cordelia Street in Pittsburgh, PA. Cordelia Street was littered with cookie cutter houses, suburbanite-like city-dwellers, and a general aura of despair. Paul's room was no different. Paul felt that his abusive father, uncaring teachers, and classmates who misunderstand him aren't worthy of his presence and company. One of the reasons Paul may not have fit in was because there is a chance that he was learning disabled. Paul worked at Carnegie Hall as an usher. It is here that Paul's real love lies. Paul lost himself in the music of the symphonies, the characters of the plays, and in the artful scenery. Paul also enjoyed gallery art, as evidenced by the hours he spends in an art gallery, staring at one painting, before his shift at Carnegie one night. He became lost in seemingly all forms of creative expression, whether it is a floral arrangement in a shop window or an orchestral swell at the beginning of a symphony. It is at Carnegie Hall that Paul became struck by the glitter and the starlight of the stage. He was not star struck in the sense that he wanted to perform in any way, he was simply content to observe others' performances. He is struck in the sense that he wants to live the way the characters in the plays do. He imagines them living to all the extent of their money, glutting on beautiful music, art, and life. Paul, unfortunate for him, was,...

Indonesia Crisis As An Example :: essays research papers

Indonesia’s Crisis: The Lesson for China introductionIndonesia, as we have long predicted, is coming apart. This process has a great deal of relevance to China, whose army, like Indonesia’s, was accustomed to making lots of money and now resents the fact that the good times are over. In both countries, making money became the basis for military loyalty to the regime, which in turn needed the army as guarantor. But in China, as in Indonesia, the military is no longer making money, and China has banned its officers from business. Now Beijing is creating international tension to soak up the military’s energy and resentment. But in the end, the guarantor of the regime can bring its death, leaving warlords poised to take power. ANALYSIS We have long argued that the Asian economic meltdown, as its ultimate legacy, would politically reconfigure Asia. We meant this in both the international and domestic sense: Nations would behave differently after the meltdown than they did during the past generation of extraordinary prosperity. The reconfiguration of Sino-American relations is an obvious manifestation of this. But it is the domestic political changes that are the most profound and will have the most impact on international relations. It should be obvious that an economic transformation of the magnitude we have seen cannot help but have equally dramatic political consequences. Asia is obviously a diverse region. It goes without saying that the economic meltdown will affect Japan’s politics dramatically differently than Malaysia’s. However, events during the last week have drawn our attention to one area of commonality: the effect of the economic crisis on the military in China and in Indonesia. These two countries are not usually lumped together; they differ in profound ways. But they share this: they have both used their military forces for three missions – protection against foreign enemies, enforcement of internal security and development of the economy. During the previous generation, the latter role became more and more important for both the Chinese and Indonesian militaries. But Asia’s recent economic crisis, the states and circumstance have forced both militaries to de-emphasize their economic roles. Not only are the militaries not happy about this, but their unhappiness could destabilize their respective regimes. Quite apart from the truly disturbing prospect of an Asia dealing simultaneously with both Chinese and Indonesian instability, there are important lessons to be learned from the way in which each country used the military and the consequences of that use.

A history denied

History plays a very significant role in the development and stability of any nation. It serves as an indicator and in some ways an explanation of the current state of any nation. Citizens take pride in recalling or reminiscing how their nation has survived and emerged triumphant over the years. Things that had happened in the past, which inspired the current state and will continue shaping the future. The case of tracing the history of Africa seems to be a controversial one. Historians have raised issues over the historical accounts of the African to be deceiving as most of them were developed by Europeans.Some, who found discrepancies with the European documented or written history, suggested a restudy or a rethinking of the real African History as the new generation of Africans has all the right to be fed with appropriate and unbiased information.In revisiting the African history, historians, instead of relying on European references studied other sources like the African culture (oral tradition and language), and the African art which all served as alternative foundation for the African history.What a harsh reality for the Africans to have this tremendous experience – they had more than enough of the discrimination and worse, even their very own history was denied to them.Europeans have, in one way or another altered or edited the reality behind the history of the Africa n people in different aspects of their way of living in the past.   In terms of civilization, they have built early civilizations in Africa but the Europeans made them believe that Africa was not capable of establishing civilization then.The problem with the true African history was the lack of sufficient tangible evidences. Most of the history was passed from one generation to another through verbal story telling.Such method made it difficult to preserve the genuine history, which gave the Europeans the opportunity to transcribe and document the flow of events in a manner that would please them and that would justify the slavery and prejudice Africans experiences with the Whites.The European’s version of the African history gave credit to the former as the beginners of civilization there. And they were successful in spreading a false history that favored them and emphasized that they were indeed the superior race.   But there were evidences found later that Africans had been civilized even before the Europeans arrived.They were already educated on spinning and weaving cloth, twisting and plaiting ropes, and even raising domestic livestock. But these information were all denied from them and were revealed just recently.Another gloomy reality concerning the African history was the denial of the cultural heritage. Native works of arts and masterpieces were illicitly brought and displayed in museums outside of Africa, defying the fact that they were African original creations and possessions. Different artifacts found in Mapungubwe Hill were evident of the wealth and differentiation of the Africans before the Whites took over.he denial of the truth for the Africans on what truly happened in their past had greatly affected how they perceive themselves. The issue on racism, also introduced by the Whites, left the African people unconfident about themselves and their culture. They created a mindset that the better race is that who have originated form the West.To date, Africans have not seized building and developing their own, true history. From all the challenges and struggles they have surpassed, they will continually.It will be imperative that the new generation of Africans and historians as well, learn to view their very own history from the perspective of their ancestors rather than from the European point of view. The future African generation hopefully will not be confused anymore between the real and the invented African history.References:Giblin, J. â€Å"Issues in African History.†   Art and Life in Africa Online. 07 March 1999. 1 May 2007 â€Å"The Crawfurd.dk.† History of Africa. 1 May 2007   

Computer Information Specialist Essay

Computer Information Specialist, Inc. (CIS) filed a protest of the award of a contract to Open Technology Group, Inc. (OTG). CIS responded to a request for proposals (RFP) No. NLM-030101/SAN by the Department of Health and Human Services for telecommunications support services at the agency’s Bethesda, Maryland facility. The solicitation specified a requirements contract with fixed hourly rates for a base year with four 1-year options. The agency intended to award the contract based on â€Å"best value† with several non-price criteria as the most heavily weighted factors. Proposals were to include fully-loaded, fixed hourly rates for labor categories. The agency received numerous proposals and established a competitive range of four firms after initial evaluation. The range included CIS as well as OTG the eventual awardee. Following the contract award to OTG; CIS underwent an agency debrief and subsequently filed a protest asserting that both its proposal and the propos al of OTG were misevaluated. Issues Agencies are required to evaluate proposals based solely on the evaluation factors identified in the solicitation. Furthermore, according to Federal Acquisition Regulations, they must adequately document the reasons for their evaluation conclusions (FAR § 15.308). GAO recommended to the agency was to, at a minimum reevaluate both proposals to ascertain if they were evaluated based on the evaluation factors and to determine if adequate rationale were articulated. Decisions (Holdings) Anthony H. Gamboa, General Counsel wrote the recommendation. The protest was sustained. Reasoning (Rationale)   GAO concluded that the Department of Health and Human Services misevaluated the proposals of both CIS and OTG, contract awardee. In addition, they found that the agency’s misevaluation was prejudicial to CIS, â€Å"since there is a reasonable possibility that, but for the agency’s errors, CIS might have been selected for award notwithstanding its higher price.† Separate Opinions No dissenting opinion was published with GAO’s decision. Analysis GAO analyzed the proposals from both CIS and OTG against the RFP’s stated evaluation criteria. The Department of Health and Human Services’ source selection team consisted of five evaluators. In the case of the proposal by CIS, the initial evaluation criticized the proposal for not offering personnel that met all of the solicitation minimum personnel experience requirements. CIS revised their proposal to cure this deficiency. In further evaluation, four of the five evaluators scored this area higher than the initial proposal. However, the fifth evaluator scored the proposal dramatically differently. In the first evaluation, only cursory notes were provided to support conclusions. In the second evaluation, most evaluators still provided limited support. However, the fifth evaluator provided comments. Many of the comments were either inaccurate or held not relation to evaluation criteria. With regard to the OTG proposal, GAO determined that the solicitation failed to meet two of the evaluation criteria and should not have been accepted in the competitive range. It was also recommended that the agency terminate the contract awarded to OTG for the convenience of the government and make award to the firm found to be in line for award. Furthermore CIS was to be reimbursed all costs associated with the protest to include legal fees.
