Summary The main aim of this report is to highlight differences between two languages based on the program developed for both the languages. A reader-writer program was created in two languages, i.e. JAVA and PYTHON. The program creates 4 threads each of which performs 5 read/write operations to the shared location. These threads simulate a coin flip. If the coin flip results in Heads (H) - Reading from the shared location is performed and if the coin flip results in Tails (T) – Writing to the shared memory location is performed. To achieve this concurrency and parallel programming, Semaphores and Monitor is used. Based on the output of the programs, two languages are then differentiate based on certain given comparison and evaluation criteria and concluded which of the two chosen languages is better for concurrency and simultaneously programming. Keywords: Semaphore, Monitor, Reader-Writer, Concurrency, Thread. 1. Introduction Concurrency and Parallel programming in Computer Science, refers to act of performing several computations simultaneously by interacting with each other and using the same memory location to perform various operations. Reader-Writer is a common example of concurrency and parallel programming. In this problem, multiple threads access the same memory location at any given time. Two or more threads can read from the shared location at the same time, but same cannot be said for the writer. When a writer thread is writing, no other thread, whether it’s a
Q2. Discuss the advantages and disadvantages for the idea of single language for all programming do- mains?
Of the more than 6,700 languages spoken in the world today, half are at risk of disappearing by the end of this century. Every two weeks, the last living speaker of a language dies, taking the language with him. The lingua franca that Global English has become, has a lot of disadvantages for our society and for our personal development. Approximately two billion people from different countries speak this language nowadays and as a result other languages become extinct. Not only do entire languages become extinct when everybody uses the same language to communicate, also languages harbour all kinds of human knowledge, which will be lost forever if the language will be forgotten. Furthermore, learning a new language helps the brain to perform more efficiently. Moreover, a whole culture with its unique traditions and celebrations will be lost forever.
Language is a crucial element in our life. Without language, we will not be able to communicate with others efficiently. Unlike music or any other types of sound, speech sounds are well-organized. It contains a lot of information when they are produced. By the time we were born, we got the potential to speak, read, learn and understand language. The environment starts our journey to the world of language. Even though there are many languages around us, we can always distinguish our own type of language. Surprisingly, infants also do the same. How can they possibly do that? There are several reasons can explain this phenomenon.
The issue of language difference may play a role in understanding between the child and the teachers, and other children. The issue extends beyond the spoken language to include approaches in a school setting. Perhaps the aggressive behavior, as well as withdrawal from group participation, is a result of inadequacies in the ability to understand between the native and non-native child. Alex has a completely different cultural background from that of other children. The methods of command and even the language tool used in the school is quite different from how he was brought up.
This article points out the outstanding similarities and differences between English and Kihaavu languages. First, it looks at those areas of similarities and differences so as to predict errors a Kihaavu native speaker learning English is likely to encounter. Second, it suggests some techniques in learning as a remedy to difficulties.
There are many differences that we can find between the COBOL programming language and PHP language. Both had different upbringing, different purpose to serve, different features, and different strengths and weaknesses. Also, it is interesting to note that one is a legacy language while one is much more modern, which we will explore these influences on how time and expectation of modern society could have affected the latter language.
The programming language used to develop an application not only affects the performance of the application.
Dervin (1993) takes a purely theoretical view of difference. She views difference as fundamental and postulates that language as symbolic product produced by humans whose lives are at least in part symbolic confounds the differences between humans. Symbolic language also confounds the differences seen in the intuitions produced by humans. It is her contention that language is the key to understanding difference. She utilizes Nouns, Verbs and language structure as metaphors for understanding difference. She posits that when we search for patterns with research tools deviations from the a pattern constitute difference and that we must then locate that difference into a conceptual frameworks the most common being culture or agency.
The tremendous increase of system concurrency from hundreds of thousands to hundreds of millions will be a big challenge for system software to manage and for applications to get good performance at this level of parallelism. As we all know that almost all of today’s large-scale applications use the message-passing programming model (MPI) together with traditional sequential languages (C, Fortran, C++), but the new architectures with many cores per chip and parallelism in the millions will make this programming model more problematic and less productive in the future. Thus a new approach is needed. Like
Ever since programming languages was introduced there have been some issues or problems with each and every programming language from low lever programming language BASIC to high level language C and C++. As there should be so many enhancements to be made in each of those programming languages, engineers from Sun Microsystems wanted to develop a new environment and to implement new art of programming language with should be simple, efficient, durable, portable, powerful, well secure and easy to understand. When java was designed it was a programming language later-on due to its easy, simple and flexible nature it was designed for web applications as well.
Parallel transmission are packets of data sent at the same time, usually over more than one transmission line. This results in faster transmission of data. Many times, this data is sent sporadically, and start and stop
The above statement explains that to understand language, one must learn to view language objectively, without any meaning or context added to the language. This would present the reader or audience with nothing but pure language and with no other meaning or slang that would cause some language to mean something else in a different context. For example, if you were to view language as an object without any social context, then the word ‘book’ is simply a book, a collection of pages that tell a story or provide information. With social context however, a person may say they want to ‘book’ a table at a restaurant, which then means that they want to reserve a table and are not talking about an actual book. This difference between language
The project clearly introduces us to the concepts of distributed memories, remote procedure calls, shared memory, concurrency, etc. thereby leveraging our knowledge and
In this section, I am all for the effects of the mother language on the second language. ELLs are influenced by their backgrounds and their experiences shape their knowledge in the new language they learn. The research findings revealed the effects of native language on the new language. There are many examples of those learners who successfully they do in the target language and that because of the level of their knowledge in their native language.
Dabrowska’s findings (2008a) with respect to Polish genitives are consistent with the claim that there is variation in people’s linguistic knowledge who speak the same language, since the grammatical rules they use in producing genitives are different from one to another. These findings rebut Roeper’s opinion (2012:293) that the accuracy of the results might only be in the case of “another grammar is produced”. More than that, Roeper suggests that requires to present “consistent alternative behaviour”. A competing view is championed by Dabrowska (2012b:329), where she argues that the interpretation of the speakers’ disparity in knowing a rule is as result of those speakers’ have disparate syntactic competence. Additionally,
