Recently in the media and on the Internet we increasingly encounter the phrase “IT”: IT news IT specialists, etc. But not everyone knows what it is. No, of course, among people with technical education that is closely associated with electronics and various computer equipment it is no longer a question. But an ordinary man in the street can be puzzled by this pair of letters. Let’s face it — what is IT and what is it for?
So the abbreviation “IT” is short for Information Technology. If you anywhere meet the Information and Communication Technology, it will be all one and the same. These include the processes and methods of search, collection, storage, processing of information and its provision, distribution. Later, information technology was classified as the methods and techniques of use of computer equipment for collection, storage, processing, transfer and use of data.
Information Technology (IT) is a set of interrelated scientific, technological, engineering sciences, associated with the methods of effective labor organization of people who are involved in processing and storage of information using computer technology, methods of organization and interaction with people and production equipment, their practical application, as well as social, economic and cultural problems that are connected with these methods. This area requires complex training, huge initial costs and must be supported by knowledge-based technique. In simple words IT-technologies include everything associated with creating, storing, perception and transmission of information. It’s their product. But the tools used for this today are computer technologies. The development of information technology leads to the fact that goods and services are more accessible to every Internet user. For example, there is nothing difficult for an ordinary person to order and buy medicines in sg-tabs.com with delivery included, maintaining anonymity and saving time.
Although they often go back and associate IT first with computers, tablets, smartphones and other computing facilities and electronic gadgets, and then with the information. This is not surprising because now most of the time a person receives information from the global web with the help of these devices. But not so long ago this role was played by radio and TV, and earlier it had been a book. The basic principles of modern IT-technologies: — Interactive mode. This is so-called “dialog” mode — impact — response of computer — human impact — response of computer — human impact — response of computer — etc. — Nice graphic display capabilities of illustrations, images, and video content. — Personality. The implication here is affordability, handy size, their ease of use by the user and a mobility move. — The ease and simplicity management of the information devices. — Easy storage, modification and transmission of accumulated information. Requirements for new information technology the cost of the devices are available for an individual customer; — usability and autonomy of operation of the apparatus, its adaptability to a variety of applications: in the management, science, education, life; — familiar interface of the operating system and application programs; — high reliability of the devices; — security processes for obtaining, storing and transmitting information.
Currently IT market provides a wide range of solutions developed by different manufacturers on the same or different principles, architectures, and functional capabilities. The problem of choosing a specific technology for the consumer involves the risks associated with determining the functionality of the technology, its prospects, market position, etc. The error in strategy of choice of IT threatens the consumer to pay a substantial cost for pairing the selected technology with the other popular ones available on the market, for the extension of the performed functions, and often for the acquisition of other, more advanced technology.
Therefore, during selecting a specific technology, a consumer in addition to the traditional technical, economic and organizational factors should take into account the general trends and features of development of the IT market.
We can distinguish the following main stages in the development and application of IT.
At the first stage we had a situation in which there were many manufacturers of a variety of technologies. The implementation of the same functional tasks in these conditions did not ensure compatibility of technology both “bottom up” – with the appearance of new versions, and “horizontally” – made by different manufacturers.
The second logical step was the use of IT-standardization. It began to develop some common approaches to the implementation of specific IT, which helped to ensure the compatibility of solutions implementing the same IT by different manufacturers. A situation arose when there were a lot of technology manufacturers; nevertheless it provided them some (decision of the private task interaction) compatibility.
Well, now you possess the basic terminology and have at least a general idea of what modern IT technologies are, how they work and where they are used.
