This automation tool for programming codes directly into the processor. Machine instructions are described in the form of mnemonic operations, to achieve a sufficiently high modifiability of code. Since the set of commands on different processors are different, then the compatibility can not speak. Using assembler appropriate in cases where it is necessary to interact directly with hardware, or get more effective for some part of the program due to higher control over code generation. Many writers such as Ray Kurzweil offer more in-depth analysis. C and C + + At the heart of the language C – Requirements System Programmer: full and effective access to all computer resources, facilities high-level programming, portability of programs between different platforms and operating systems. C + +, while maintaining compatibility with C, introduces object-oriented programming, expressing the idea class (object) as a udt. Thanks to these qualities, C / C + + took the position of a universal language for all needs.
But its use may be ineffective where it's needed to get ready for use the result as soon as possible, or where it becomes unprofitable itself a procedural approach. Delphi – is not a continuer of Borland Pascal / Borland C, its niche – that is, rapid creation of applications (Rapid Application Developing, RAD). These funds allow, as soon as possible to create a working program from pre-built components, without wasting a lot of effort on the small stuff. A special place in these systems hold the possibility of working with databases. Lisp – An Algorithmic language developed in 1960 by J.
McCarthy and designed for manipulating lists of data elements. Used mainly in university laboratories in the usa to address the problems associated with artificial intelligence. In Europe, for work on artificial Intellect prefer to use Prolog. Prologue – high level programming language declarative, intended for developing systems and applications of artificial intelligence. Belongs to the category of languages fifth generation. Was developed in 1971 at the University of Marseille (France), is one of the widely used and constantly develops languages. His latest version of Prolog 6.0 logo – high level programming language, developed in languages. The most common versions of the language is fortran iv, fortran 77 and Fortran 90. Used on all classes of computers. The latest version is also used on computers with parallel architecture. Java as a shining example specialization, Java emerged in response to the need for a perfect portable language program which effectively executed on the client side www. In accordance with the specific environment, Java can be a good choice for the system, built on the Internet / Intranet technology. In conclusion, we note that from a professional point of view is not so important what language and in what environment works as a programmer, but as he gets the job done. Changing hardware and operating system. New problems arise from a variety of subject areas. Thing of the past and new languages. But there are people – those who write and those for whom they write new programs, and whose quality requirements are the same regardless Depending on these changes.
To date, relevant to the types of information technologies are developing an avalanche. Including specialists in this field in a state of continuous development of the qualification of knowledge to keep pace with the continuous updates and be informed of developments. But to the layman the rate of development of information industry and in fact very clever. And this at the moment, without doubt, leading the basis of information in the industry need to learn everything. In order to be able to understand the complex situations of information reality, you need timely assistance of experts. Well or walkthrough that was opportunity to suggest how to use specific features of software content. Especially taking into account that different programs occur daily, and with them must not only learn, but also normally interact. Find the resources where it would be possible to acquire data from very different areas of information of new products, starting from the dns setting and ending with step by step instructions associated with certain computer filling in our time is not able to present much difficulty.
However, the claim that many such sources, in fact impossible. Often these resources are either fully terminology assembly of articles that are able to understand only the experts, or overly simplistic and not always universal algorithms work. Yet the real find, including data that will not be available only to professionals, as well as ordinary users, and in this case is correct and detailed. For different users interact with databases and information or e-mail systems is a real pain. However, all about this that they have not received detailed explanations, which would be as soon as you can simply explains to the principles of a particular program. In this case, even for the masters especially the interaction with specific Web server or the individual terminals may not be particularly scrutinized. After all, including the activities of common wasps vindous able to open the other positions. No secret that the windows to create and Many other moments, such as organizing a remote access can, including the experts do not face such issues previously cause certain difficulties. Exceptionally literate detailed explanations allowed to find a dignified way out of difficult situations. In addition, the subject directories have a chance to pick and ready-made scripts and other materials that make it easier to work activities specialist.
With every passing day, the Internet has become a significant part of this life. At the moment, for many people the network – in reality, is, in general, their place of work, bringing a very good form of income. At the same time needed will highlight that fact thanks to the Internet a huge number of businessmen have in real life, whatever kind of business activity came to a noticeable extent to raise their own revenues. It became available as a result of the opening of a global network of a particular representation of private enterprise, or rather the site. Because using the Internet portal is available to bring an impressive population of a global network of information about these or other products and services possible.
At the same time completely independently because, for some problems in practice, there is your own website in a global network of, say, for example, to promote goods or same services and perhaps for a possible profit from being on the pages of portal advertising, make sure every Web site administrator to be in this time of struggle for user. Understandably this can be attributed to the large number of sites and in addition to competition, but also to a great extent with modern principles of indexing pages in general, which produce different robots Internet search engine. In order for a web resource occupied an advantageous position among the issuance of search engines, it must be optimized specifically for those requirements, in fact that clearly presents a robot search system.
For example – the result of perform a certain task should be a 10% reduction in execution time of the application of IT-service; Develop programs to address each objective; concretization of the project implementation – the distribution of human and financial resources, definition of areas of responsibility for the tasks; Implementation of the project; Revision and correction system performance up to the introduction. In this step, possibly as a return to the stage formalization of performance indicators, and on the very first stage – the formalization of the strategic objective method bsc is primarily a tool for creating management strategies and is often used as part of the IT-oriented techniques of process management. However, use of bsc methodology for it projects implies that the balanced scorecard is used in the organization, otherwise the use of bsc could cause some difficulties. The rapid economic justification (Rapid Economic Justification, REJ) – a technique that was developed by Microsoft. tco is a development methodology by establishing a compliance cost it project priorities of the business process. In developing the methodology was tasked with financial justification of it investments. The key idea of a technique – look at it from the perspective of the business priorities of the company, strategic plans for its development, and key financial indicators (ROI, etc.). rej methodology consists of five consecutive stages: Binding targets and key performance indicators of it project to the business goals of the organization (this stage has much in common with technique BSC); making the choice on the list of "required features", largely consistent with the criterion "Benefits" methodology "The total economic effect (TEI); evaluation of profits and costs using the methodology "Total Cost of Ownership (TCO); risk assessment project on the eligibility criteria chosen solution to the original design, implement the chosen solution, its operating and financial risk; Calculation of financial indicators project implementation, involving the calculation methods "Net present value (NPV), Internal rate of return (IRR), Economic value added (EVA), The return on investment (ROI) and others.
